If a 12-sided fair die is rolled twice, find the probability that both rolls have a result of 8.
Answer:
1 in 144
Step-by-step explanation:
There is one 8 on a 12-sided die, so the probability of rolling an 8 once is [tex]\frac{1}{12}[/tex].
We are rolling twice, so [tex](\frac{1}{12})^{2} =\frac{1}{144}[/tex].

Determine the probability of having 2 girls and 3 boys in a 5-child family assuming boys and girls are equally likely.
The probability of having 2 girls and 3 boys in a 5-child family is 5/16
What is Probability ?Probability is the likeliness of an event to happen .
Total Probability of having 5 kids as boy or girl is 2⁵ = 32
The probability that there is 3 boys in the 5 children and remaining two are girls
[tex]\rm ^5C_3[/tex]
= (5*4*3*2*1)/(2*1)(3.2.1)
= 10 ways
probability of having 2 girls and 3 boys in a 5-child family is
=10/32
= 5/16
Therefore , the probability of having 2 girls and 3 boys in a 5-child family is 5/16

Find the volume of the sphere below. Leave your answer in terms of pi.
Answer:
C) 972π
Step-by-step explanation:
Volume of a sphere formula:
V = 4/3πr³
Given:
r = 9
Work:
V = 4/3πr³
V = 4/3π9³
V = 4/3(729)π
V = 972π

Solve the system of equation
Answer:
x = 0
y = 1
z = -4
Step-by-step explanation:
6x + 4y + 1z = 0 => z = -6x -4y
If 12x - 4y - 5z = 16, then
12x - 4y - 5(-6x - 4y) = 16
12x - 4y + 30x + 20y = 16
42x + 16y = 16 => 21x + 8y = 8
then y = (8 - 21x)/8
if -24x - 4y + 5z = -24
-24x - 4y + 5(-6x -4y) = -24
-24x - 4y - 30x - 20y = -24
-54x - 24y = -24 => -9x - 4y = -4
substitute y = (8 - 21x)/8
then -9x - 4(8 -21x)/8 = -4
-9x - 1/2(8 -21x) = -4
times 2 in both side
-18x - (8 - 21x) = -8
-18x - 8 + 21x = -8
3x = -8 + 8
3x = 0
x = 0
then y = (8 - 21x)/8 = (8 - 21(0))/8 = (8 - 0)/8 = 8/8 = 1
then z = -6x -4y = -6(0) - 4(1) = 0 - 4 = -4

Assume that the weight of cereal in a "12.6 ounce box" is N(µ,0.42). The Food and Drug Association (FDA) allows only a small percentage of boxes to contain less than 12.6 ounces. You collect a random sample of n = 35 boxes and find that the sample mean is 12.8. Test the null hypothesis H0: µ = 13 against the alternative hypothesis HA: µ < 13 at level of significance α = 0.01
Answer:
We reject the null hypothesis and accept the alternate hypothesis, that is, that the mean is less than 13 ounces.
Step-by-step explanation:
The null hypothesis is:
[tex]H_{0}: \mu = 13[/tex]
The alternate hypotesis is:
[tex]H_{a}: \mu < 13[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
13 is tested at the null hypothesis:
This means that [tex]\mu = 13[/tex]
N(µ,0.42)
This means that the standard deviation is 0.42, that is, [tex]\sigma = 0.42[/tex]
You collect a random sample of n = 35 boxes and find that the sample mean is 12.8.
This means that [tex]n = 35, X = 12.8[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{12.8 - 13}{\frac{0.42}{\sqrt{35}}}[/tex]
[tex]z = -2.82[/tex]
Pvalue of the test:
The pvalue of the test is the pvalue of z = -2.82.
Looking at the z table, z = -2.82 has a pvalue of 0.0024
0.0024 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis, that is, that the mean is less than 13 ounces.

A cone has the same radius and height as a cylinder which has greater volume the cone or the cylinder
Answer:
The cylinder has the great volume
Step-by-step explanation:
The volume of a cone = (h/3)πr²
The volume of a cylinder = hπr²
The only difference is that h is divided by 3 for the volume of a cone, making the total volume of a cone smaller than the volume of a cylinder with the same radius and height.

Yolanda painted 2/5 of a wall in 40 minutes. If she keeps painting at the same rate, how much longer will it take her to finish painting the wall
Answer:
60 minutes
Step-by-step explanation:
She painted 2/5 of the wall.
She still needs to paint 3/5 of the wall.
3 is 50% more than 2, so 3/5 is 1.5 times 2/5, so it will take her 1.5 times the time it took so far.
1.5 * 40 minutes = 60 minutes.
Answer: 60 minutes
