Answer:
The first droplet will hit the ground after about 1.54 seconds.
The second droplet will hit the ground after about 1.6 seconds.
Thus, the first hits the ground first.
Step-by-step explanation:
We are given the function:
[tex]y=-16r^2 + 38[/tex]
Which represents the height y in feet of a water droplet t seconds after falling from an icicle.
Part A)
We want to find the time it took for the water droplet to hit the ground.
When it hit the ground, its height y above ground will be zero. Therefore, we can let y = 0 and solve for r:
[tex]0=-16r^2+38[/tex]
Subtract 38 from both sides:
[tex]-38 = -16 r^2[/tex]
Divide:
[tex]\displaystyle r^2 = \frac{38}{16} = \frac{19}{8}[/tex]
And take the principal square root of both sides:
[tex]\displaystyle r= \sqrt{\frac{19}{8}} = \frac{\sqrt{38}}{4} \approx1.54\text{ seconds}[/tex]
So, the first water droplet hits the ground after about 1.54 seconds.
Part B)
We want to determine how long it will take for a water droplet to hit the ground from a height of 41 feet.
From the original equation, if r = 0, then y = 38. So, the initial height was 38 feet.
Then we can modify the function into:
[tex]y= -16r^2 + 41[/tex]
In this case, when r = 0, the starting height y is 41 feet.
Again, let y = 0 and solve for r:
[tex]0 = -16r^2 + 41[/tex]
Isolate:
[tex]\displaystyle r^2 = \frac{41}{16}[/tex]
And take the principal square root of both sides:
[tex]\displaystyle r = \sqrt{\frac{41}{16}} = \frac{\sqrt{41}}{4} \approx 1.6\text{ seconds}[/tex]
So, the second drop will hit the ground after approximately 1.6 seconds.
And in conclusion, the first drop will hit the ground sooner (as expected).

Solve triangle ABC. (If an answer does not exist, enter DNE. Round your answers to one decimal place. Below, enter your answers so that
∠A1 is smaller than ∠A2.)
b = 129, c = 168, ∠B = 48°
Angle A1 Angle A2
Angle C1 Angle C2
side a1 side a2
Answer:
∠A1 = 27.4°, ∠A2 = 56.6°, ∠C1 =104.6°, ∠C2=75.4°, a1 = 79.9 and a2 = 144.9
Step-by-step explanation:
From Sine rule
[tex]\frac{a}{sinA}=\frac{b}{sinB} = \frac{c}{sinC}[/tex]
∴ b / sinB = c / sinC
From the question,
b = 129, c = 168 and ∠B = 48°
∴ 129 / sin48° = 168 / sinC
Then, sinC = (168×sin48)/129
sinC = 0.9678
C = sin⁻¹(0.9678)
C = 75.42
∠C2=75.4°
and
∴∠C1 = 180° - 75.4°
∠C1 =104.6°
For ∠A
∠A1 = 180° - (104.6°+48°) [sum of angles in a triangle]
∠A1 = 27.4°
and
∠A2 = 180° - (75.4° + 48°)
∠A2 = 180° - (123.4°)
∠A2 = 56.6°
For side a
a1/sinA1 = b/sinB
a1/ sin27.4° = 129/sin48
a1 = (129×sin27.4°)/sin48
a1 = 79.8845
a1 = 79.9
and
a2/sinA2 = b / sinB
a2/ sin56.6° = 129/sin48
a2 = (129×sin56.6°)/sin48
a2 = 144.9184
a2 = 144.9
Hence,
∠A1 = 27.4°, ∠A2 = 56.6°, ∠C1 =104.6°, ∠C2=75.4°, a1 = 79.9 and a2 = 144.9

A) -2
B) 2
C) -8
D) -1.5
E) 11.5
F) 8
Answer:
2, 8
Step-by-step explanation:
-1/2x^2 + 5x = 8
-x^2 + 10x = 16 (Multiplying both sides of the equation by 2)
-x^2 + 10x - 16 = 0
x^2 - 10x + 16 = 0 (changing the signs)
x^2 -2x -8x +16 = 0
x (x-2) -8 (x-2) = 0

The value of the test statistic is the z-score z = -0.88
What is a z-score?The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.
The Z-score is calculated using the formula:
z = (x - μ)/σ
where z: standard score
x: observed value
μ: mean of the sample
σ: standard deviation of the sample
Given data ,
Let the test statistic value be represented as z
Now , the probability of emergency room visitors are insured is q = 0.54
The total number of patients n = 120
The number of patients that were insured = 60
So , the percentage of people that were insured p = 60/120 = 0.5
Now , test statistic value z = ( p - q ) / [ √ ( q ( 1 - q )/n² ]
The value of z score is
z = [ 0.5 - 0.54 ] / √ 0.54 ( 1 - 0.54 ) / 120²
On simplifying the equation , we get
The value of z score is z = -0.88
Hence , the test statistic is z = -0.88

Suppose that you draw a random sample of 36 cans.
a. Find the probability that the mean weight of the sample is less than 5.97 ounces.
b. Suppose your random sample of 36 cans of salmon produced a mean weight that is less than 5.97 ounces. Comment on the statement made by the manufacturer.
Answer:
a) 0.0038 = 0.38% probability that the mean weight of the sample is less than 5.97 ounces.
b) Given a mean of 6.05 ounces, it is very unlikely that a sample mean of less than 5.97 ounces, which means that the true mean must be recalculated.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 6.05 ounces and a standard deviation of .18 ounces.
This means that [tex]\mu = 6.05, \sigma = 0.18[/tex]
Sample of 36:
This means that [tex]n = 36, s = \frac{0.18}{\sqrt{36}} = 0.03[/tex]
a. Find the probability that the mean weight of the sample is less than 5.97 ounces.
This is the p-value of z when X = 5.97. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{5.97 - 6.05}{0.03}[/tex]
[tex]Z = -2.67[/tex]
[tex]Z = -2.67[/tex] has a p-value of 0.0038.
0.0038 = 0.38% probability that the mean weight of the sample is less than 5.97 ounces.
b. Suppose your random sample of 36 cans of salmon produced a mean weight that is less than 5.97 ounces. Comment on the statement made by the manufacturer.
Given a mean of 6.05 ounces, it is very unlikely that a sample mean of less than 5.97 ounces, which means that the true mean must be recalculated.

Your friend has offered to let you have his ticket if you will give him your ticket plus one dollar.
Required:
Build an influence diagram for this problem.
Solution :
I have a lottery ticket that will pay off $ 10 with a 45% chance and a friend of mine has a chance of 20% by paying off $ 25.
It is based on Double risk dilemma.
Individual --- trade ticket (-1) ----24 (win(25) (0.20))
----- -1 (lose ) (0.80)
----- keep trade -------10 (win 10) (0.45)
----- 0 (lose) (0.55)
Next, solve the decision tree using expected monetary value.
EVM (keep ticket) = 0.45 (10) + 0.55 (0) = $ 4.50
EVM (trade ticket) = 0.20 (24) + 0.80 (-1) = $ 4
Therefore, we keep the ticket and do not trade.
Your small business spent $40 on food and another $60 on materials. Then, you sold an item for $120, but you had to pay a $90 service fee. Finally, you were given a refund from the Internal Revenue Service (IRS) for $70. If the expression describing these transactions is the following, then how does it evaluate?
Answer:
40$+60$=100$ spent
120$sold
90$ payed
70$ refund
120 (sold) -90 (payed) =30+70 (refund) =100$ (profit)
Step-by-step explanation:
You spent 100$
And you sold and got 120 but you payed 90$ from 120$ money left is 30$
Then they refunded you (pay back the money (give you the money ))
So the money that your left with is 30$ and the refund money is 70$
So add the money that your left with is gives you 100$

Use differentials to estimate the amount of paint needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with diameter 50 m. (Round your answer to two decimal places.)
Answer:
2.75 m²
Step-by-step explanation:
From the information given:
the thickness of the paint = 0.07 cm = (0.07/100) m
= 0.0007 m thick
the diameter hemispherical dome = 50 m
∴
radius of the dome = 50m /2 = 25 m
The volume of a hemispherical dome is expressed as:
[tex]V = \dfrac{2}{3}\pi r^3[/tex]
Thus, the change in the volume now is:
[tex]\dfrac{dV}{dr} = \dfrac{2}{3}\pi *3 r^2[/tex]
[tex]{dV} = \dfrac{2}{3}\pi *3 r^2 (dr)[/tex]
[tex]{dV} = 2 \pi r^2 (dr)[/tex]
∴
dV = 2π × (25)² (0.0007)
where;
dr = 0.0007
dV = 2π × (25)² (0.0007)
dV = 2.75 m²

Answer:
Step-by-step explanation:
To find the times that the height is 26 feet, we set the position equation equal to 26 and solve for t:
[tex]26=-16t^2+40t+4[/tex] and
[tex]0=-16t^2+40t-22[/tex] and factor that however you are factoring in class to solve a problem like this. When you do that you get
t = .86 seconds and t = 1.68 seconds. That means that .86 seconds after the ball is thrown into the air, it reaches a height of 26 feet; it goes up to its max height and then gravity takes over and pulls it back down. When this happens, it will pass 26 feet again on its way back down. This second time is after 1.68 seconds.

how would you you find the answer for
-5x + y = -2
-3x+6y=-12 ? having some issues with how to this
9514 1404 393
Answer:
(x, y) = (0, -2)
Step-by-step explanation:
When solving by substitution, you usually want to find an expression for one of the variables in terms of the other. So, the first thing you look for is an equation that has a coefficient of 1 or -1 on one of the variables. Recognizing that the second equation's terms all have a common factor of 3, you basically have two choices.
Substitute for yUsing equation 1, you can write an expression for y:
y = 5x -2 . . . . . . add 5x to both sides
Then substituting this into the original equation 2, you have ...
-3x +6(5x -2) = -12
27x -12 = -12 . . . . . . . simplify
27x = 0 . . . . . . . . . add 12
x = 0 . . . . . . . . . divide by 27
y = 5(0) -2 = -2 . . . . find y using the expression for substitution
The solution is (x, y) = (0, -2).
__
Substitute for xIf you decide you'd rather substitute for x, you can solve the second equation easily for x.
-3x +6y = -12
x -2y = 4 . . . . . . divide by -3
x = 2y +4 . . . . . . add 2y
Substituting for x in the first equation gives ...
-5(2y +4) +y = -2 . . . . substitute for x
-9y -20 = -2 . . . . . . . simplify
-9y = 18 . . . . . . . . . add 20
y = -2 . . . . . . . . . . . divide by -9
x = 2(-2) +4 = 0 . . . . find x using the expression for substitution
The solution is (x, y) = (0, -2).

In some cases, there are no variables that have a coefficient of ±1, so you just need to "bite the bullet" and deal with the resulting fractions.

2y = 5x -2
y = 5/2x -1 . . . . expression used to substitute for y
Of course, you can multiply the equation after substitution by 2 to eliminate fractions, or just work the problem as is. The point of looking for coefficients of ±1 is to avoid having to do arithmetic with fractions. It can help avoid errors to work with integers, but ultimately the method is the same regardless of the form of the numbers.

You don't always have to substitute for the "bare" variable. Sometimes it can save steps to substitute for expressions instead of variables. If our system of equations were ...
-5x +2y = -2-3x +6y = -12You can substitute into the second equation for (2y). In that case, the second equation becomes ...
-3x +3(2y) = -12
-3x +3(5x-2) = -12 . . . . . . where 2y = 5x -2
You measure 40 watermelons' weights, and find they have a mean weight of 67 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, what is the maximal margin of error associated with a 99% confidence interval for the true population mean watermelon weight.
Answer:
[tex]35.36,44.64[/tex]
Step-by-step explanation:
Sample size [tex]n=40[/tex]
Mean weight [tex]\=x =67[/tex]
Standard deviation [tex]\sigma=11.4[/tex]
Confidence Interval [tex]CI=0.99[/tex]
\alpha==0.01
Therefore
[tex]Z_{\frac{\alpha}{2}}=Z_[0.005][/tex]
From table
[tex]Z_{\frac{\alpha}{2}}=2.576[/tex]
Generally, the equation for Margin of error is mathematically given by
[tex]M.E=Z_{\frac{\alpha}{2}}*(\frac{\sigma}{sqrt{n}}[/tex]
[tex]M.E=2.576*(\frac{11.4}{\sqrt{40}}[/tex]
[tex]M.E=4.64[/tex]
Therefore Estimated mean is
[tex]\=x-M.E<\mu <\=x +E[/tex]
[tex]40-4.64<\mu< 40+4.64[/tex]
[tex]35.36<\mu < 44.64[/tex]
[tex]35.36,44.64[/tex]
Suppose that a defendant in a first-degree murder trial has 52% chance of being convicted of murder, a 26% chance of being convicted of a lesser charge, and a 22% chance of being found not-guilty. Find the percent chance that the defendant is convicted on any charge.
Answer:
78%
Step-by-step explanation:
This question is pretty straight forward. Here we are to find the percentage probability of the of the defendants being convicted on any charge.
From the information available to us there's a 52% chance of being convicted of murder and also there's another 26% chance of conviction of something smaller. From this data available, the percentage chance that there will be a conviction is
52% + 26%
= 78%
