Which number line can be used to find the distance between (-1,2) and (-5,2)
Answers
Answer:
The number line is y = 2.
Step-by-step explanation:
We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.
The y coordinate of the two points is
same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.
Distance between the points = |-5+1| = 4
The grades of an exam whose mean is 82 and whose standard deviation is 14 are normally distributed. Anyone who scores below 55 will be retested. What percentage does this represent
Answers
Answer:
This represents 2.6803%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x - mean)/SD
here our x is 55
mean = 82
SD = 14
z-score = (55-82)/14
z-score = -1.93
So the probability that a test taker will be retested will be;
P( x < -1.93)
We use the standard normal distribution table for this
P( x < -1.93) = 0.026803
If we convert this to percentage, we have 2.6803%

Answers
Answer: the answer is choice b
Step-by-step explanation:
The data in the first table represents a linear function that has a slope of zero
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Slope (m) = change in y / change in x
From the first table, using the point (-5, 5) and (-1, 5), hence:
Slope = (5 - 5)/(-1 - (-5)) = 0
The data in the first table represents a linear function that has a slope of zero

Let X1, X1, ..., X64 be a i.i.d. random sample of size 64 from a distribution with probability density function: f(x) = 6x(1 − x), 0 < x < 1 Approximate P(0.45 < X <¯ 0.5). Hint: find µ and σ 2
Answers
Answer:
The approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.
Step-by-step explanation:
The pdf of X is:
[tex]f(x) = 6x(1-x), 0 < x < 1[/tex]
Compute the mean as follows:
[tex]\mu=\int\limits^{1}_{0} {x\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{2}-6x^{3}} \, dx\\\\=[\frac{6x^{3}}{3}]-[\frac{6x^{4}}{4}]|^{1}_{0}\\\\=2-\frac{3}{2}\\\\=0.50[/tex]
Compute the variance as follows:
[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}[/tex]
[tex]E(X^{2})=\int\limits^{1}_{0} {x^{2}\times 6x(1-x)} \, dx \\\\=\int\limits^{1}_{0} {6x^{3}-6x^{4}} \, dx\\\\=[\frac{6x^{4}}{4}]-[\frac{6x^{5}}{5}]|^{1}_{0}\\\\=\frac{3}{2}-\frac{6}{5}\\\\=0.30[/tex]
[tex]\sigma^{2}=E(X^{2})-(\mu)^{2}\\\\\sigma=\sqrt{E(X^{2})-(\mu)^{2}}\\\\=\sqrt{0.30-(0.50)^{2}}\\\\=0.2236[/tex]
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
The sample selected is of size n = 64 > 30. Thus a central limit theorem can be applied to approximate the sampling distribution of sample mean.
Compute the value of [tex]P(0.45<\bar X<0.50)[/tex] as follows:
[tex]P(0.45<\bar X<0.50)=P(\frac{0.45-0.50}{0.2236/\sqrt{64}}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{0.50-0.50}{0.2236/\sqrt{64}})[/tex]
[tex]=P(-1.12<Z<0)\\\\=P(Z<0)-P(Z<-1.12)\\\\=0.50-0.13136\\\\=0.36864\\\\\approx 0.3686[/tex]
Thus, the approximate value of [tex]P(0.45<\bar X<0.50)[/tex] is 0.3686.

Water is being drained from a container which has the shape of an inverted right circular cone. The container has a radius of 5.00 inches at the top and a height of 6.00 inches. At the instant when the water in the container is 4.00 inches deep, the surface level is falling at a rate of 0.7 in./sec. Find the rate at which water is being drained from the container.
Answers
The rate at which water is being drained from the container is;
dV/dt = 24.4 in³/s
I've attached an image showing this inverted cone with the corresponding letters to represent the height and radius.
We are given;
Radius of Cone; R = 5 inches
Height of cone; H = 6 inches
h = 4 inches
Height rate of change; dh/dt = 0.7 in/s
Looking at the image attached, we can use similar triangle property to derive the relationship;
r/R = h/H
Where r is the radius at the instant where dh/dt = 0.7 in/s
Thus;
r/5 = 4/6
r = (5 × 4)/6
r = 3.33 inches
Now, from r/R = h/H
We can write with initial values of cone and differentiate;
r/5 = h/6
6r = 5h
6(dr/dt) = 5(dh/dt)
Since dh/dt = 0.7 in/s
Thus;
dr/dt = (5/6) × 0.7
dr/dt = 0.5833
Volume of cone is given by;
V = ⅓πr²h
We can find the rate at which the rate at which water is being drained from the container using partial differentiation on the volume equation.
Thus;
dV/dt = ⅓π((2rh × dr/dt) + (r² × dh/dt))
Plugging in the relevant values, we have;
dV/dt = ⅓π((2 × 3.33 × 4 × 0.5833) + (3.33² × 0.7))
dV/dt = 24.4 in³/s

5 cm
6 cm
A 34 cm2
B 44 cm
54 cm
D 46 cm
Answers
Answer:
the answer is D 46 cm
Step-by-step explanation:
first you need to find the missing side measurements cutting in two separate figures. if one side is 2 you know the other side is also 2 same with the 4 if the top is 4 the bottom is 4 too so now you have the measurements for the first figure now you finder the area applying the formula
A=bxh
A= 4*2=8
second figure you know that one part of the rectangle top is 5 and if you add the 4 of the first figure give you the measurement of the top
5+4=9 so if the top is 9 the bottom is also 9
finally to find the other side you know the side is 6 and since you know one part of the first figure is 2 you need to subtract 6-2=4
A=bxh
A=9*4=28
once you have both you can add it 28+8=46

Answers
Answer:

Step-by-step explanation:
500*0.01=5, I think this was a question from flocabulary, next time, try to also add the answer choices.
The true statement is that the amount of money which Eddie would be charged for each monthly withdrawal is equal to $5.
What is a paycheck?A paycheck refers to a financial document issued to an employee by an employer, as payment for the work done over a specific period of time.
How to calculate the service charge.Since the interest on Eddie's monthly withdrawal is 1% (0.01), it simply means that the service charge would be calculated by multiplying his wages by the interest rate.
Service charge = 500 × 0.01
Service charge = $5.
