Adrianna uses her credit card to purchase everything! She makes payments on the 15th of each month. Each payment she makes is for the same amount, and it is automatically deducted from her savings account. At the end of the year, Adrianna’s account balance changed by - $4,203.00 due to the payments she made. What is the change in Adrianna’s account balance each month due to the payments she makes on her credit card?
Answer:
$350.25 per month
Step-by-step explanation:
We can assume she pays the same amount every month. We know that there are 12 months in a single year, so we can divide to find the unit rate.
4203 / 12 = 350.25

Alicia watched a drone take off from a bridge. The height of the drone (in meters above the ground) tttt minutes after takeoff is modeled by h(t)=−3t2+12t+96h(t)=-3t^2+12t+96h(t)=−3t2+12t+96h, left parenthesis, t, right parenthesis, equals, minus, 3, t, squared, plus, 12, t, plus, 96 Alicia wants to know when the drone will land on the ground. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. h(t)=h(t)=h(t)=h, left parenthesis, t, right parenthesis, equals 2) How many minutes after takeoff does the drone land on the ground?
Answer:
Step-by-step explanation:
Given the height of the drone modelled by the equation:
h(t)=-3t^2+12t+96
a) Rewriting this in a factored form.
From the equation, we can see that -3 is the greatest common factor. The equation therefore becomes:
h(t)= -3(t^2-4t-32)
Hence the function can also be written as h(t)= -3(t^2-4t-32)
b) The drone landed on the ground at when h(t) = 0. Substitute h(t) = 0 into the expression h(t)= -3(t^2-4t-32)
0 = -3(t^2-4t-32)
Divide through by -3
(t^2-4t-32) = 0
Factorize
t²+8t-4t-32 = 0
t(t+8)-4(t+8) = 0
(t-4)(t+8) = 0
t-4 = 0 and t+8 = 0
t = 4 and t = -8
Time can't be negative:
t = 4minutes
Hence it took the drone 4 minutes take off to land on the ground
Answer: 1) h(t)= -3 (t-8) (t+4)
2) 8 mins.

a boat leaves at noon and has a bearing of S 35 east. The boat travels at 40 miles per hour. (a) many miles south and how many miles east will the boat have traveled at 7 pm
Answer:
South =34.18 miles
East= 49.12miles
Step-by-step explanation:
We begin by calculating the distance covered in 7n hours
that is from 12 pm to 7pm which is 7 hours
so time t= 7 hours
speed= 40 miles per hours
we know that speed= distance/time
let the distance be x
40=x/7
x=40*7
x=28miles
(a) many miles south and how many miles east will the boat have traveled at 7 pm
applying SOH CAH TAO we have
For the south CAH
cos Ф=hyp/adj
hyp= 28 mile
Ф= 35°
cos 35= 28/adj
0.819=28/adj
adj=28/0.819
adj=34.18 miles
For the East SOH
sin Ф=hyp/opp
hyp= 28 mile
Ф= 35°
sin 35= 28/opp
0.57=28/opp
opp=28/0.57
opp=49.12miles

A clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest
employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000. How does this
error affect the measures of center (median and mean)?
A. The median will be the same. The mean will be too small.
B. The median will be the same. The mean will be too large
C. The median will be too small and the mean will be too large,
D. The median and the mean will both be too large.
Answer:
The correct option is B.
Step-by-step explanation:
The median (m) is a measure of central tendency. To obtain the m, we assemble the data in arising order. If the data is odd, the m is the mid-value. If the data is even, the m is the arithmetic-mean of the two mid-values.
The mean is the average value of the data set. It is computed by dividing the sum of all the values in data set by the number of values.
So, the mean considers all the values in the data set. But the median considers only one value.
It is provided that the clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000.
The highest salary will be taken into account while the computation of mean. But it would not be considered while determining the median.
So, the median salary will remain same. But the mean salary will change.
And since the highest salary is increasing from $150,000 to $1,500,000 the mean will also increase.
Thus, the correct option is B.

How many deciliters are equivalent to 9 cups? Use the conversion table to find the answer. Round to the nearest tenth.
21.3 dL
42.7 dL
213.3 dL
426.6 dL
Answer:
Answer: The correct option is (a) 21.3 dL.
Step-by-step explanation: We are given to find the number of deciliters that are equivalent to 9 cups.
Given that,
1 cup = 0.237 liters.
We know that
1 liter = 10 deciliters. So, we get
0.237 liters = 0.237 × 10 deciliters = 2.37 deciliters.
This implies that
1 cup = 2.37 deciliters.
Therefore, we get
9 cups = 2.37 × 9 deciliters = 21.33 deciliters.
Rounding to nearest tenth, we get
Thus, 9 cups are equivalent to 21.3 deciliters.
Option (a) is CORRECT.

How will decreasing the level of confidence without changing the sample size affect the width of a confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal
Answer:
Without changing the sample size the change of CI may affect the results
Step-by-step explanation:
According to Central Limit theorem the sampling distribution is given by
Z= x`- u/ σ/√n
Z has in the limit a standard normal distribution and
x`= u ± zσ/√n
From the above
x`- z∝(σ/√n) ≤ u ≤ x`+ z∝(σ/√n)
This formula is used for the confidence interval with normal population and unknown standard deviation.
But if the different values of Z∝ are used the results will be different.
If the CI of 99% or 95% or 90% is used the values of acceptance and rejection regions change and therefore the results will change.
The value of Z∝ for
∝= 0.1 is ± 1.645
∝= 0.05 is ± 1.96
∝= 0.01 is ± 2.58
Suppose we get the calculated Z value equal 2.59 but we decrease the CI from 0.05 to 0.01 the acceptance region would become rejection region and the level of confidence will change.

Have A Blessed Day!
The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, by what we should divide to the give expression to get 25%, 50% and 10%
Converting the percentage into fractions,
To change the percentage to a fraction, put the percentage number in the numerator and 100 in the denominator.
50% = 50/100 = 1/2, so we will divide it by 2,
25% = 25/100 = 1/4, so we will divide it by 4,
10% = 10/100 = 1/10, so we will divide it by 10.
Hence, The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.

the approximate mass of Mars is 6.42x10^23 kilograms. write this mass in standard notation
Answer:
642000000000000000000000 kg
Step-by-step explanation:
The approximate mass of Mars is 6.42x10^23 kilograms. It is given in scientic notation.
We need to write the mass in standard notation. It is the normal way of writing any number. To write it in standard form, we move the decimal to the right side.
The standard form will be :
6.42x10^23 kg = 642000000000000000000000 kg
Hence, this is the required solution.

Answer: b=10
Step-by-step explanation: ((0 - 8 • (b + 11)) - 4) - (18 - 19b) = 0
Pull out like factors :
11b - 110 = 11 • (b - 10) 11 • (b - 10) = 0
b-10 = 0
Add 10 to both sides of the equation :
b = 10
