Answers
Answer:
1/36
Step-by-step explanation:
the chance of rolling a 2 on a 6-sided die is 1/6 and rolling a 5 on a 6-sided is also 1/6.
So, 1/6 * 1/6 = 1/36

Geometric sequences HELP ASAP!
Answers
Given:
The table for a geometric sequence.
To find:
The formula for the given sequence and the 10th term of the sequence.
Solution:
In the given geometric sequence, the first term is 1120 and the common ratio is:
[tex]r=\dfrac{a_2}{a_1}[/tex]
[tex]r=\dfrac{560}{1120}[/tex]
[tex]r=0.5[/tex]
The nth term of a geometric sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where a is the first term and r is the common ratio.
Putting [tex]a=1120, r=0.5[/tex], we get
[tex]a_n=1120(0.5)^{n-1}[/tex]
Therefore, the required formula for the given sequence is [tex]a_n=1120(0.5)^{n-1}[/tex].
We need to find the 10th term of the given sequence. So, substituting [tex]n=10[/tex] in the above formula.
[tex]a_{10}=1120(0.5)^{10-1}[/tex]
[tex]a_{10}=1120(0.5)^{9}[/tex]
[tex]a_{10}=1120(0.001953125)[/tex]
[tex]a_{10}=2.1875[/tex]
Therefore, the 10th term of the given sequence is 2.1875.

Suppose that the number of gallons of milk sold per day at a local supermarket are normally distributed with mean and standard deviation of 486.9 and 24.01, respectively. What is the probability that on a given day the supermarket will sell between 477 and 525 gallons of milk
Answers
Answer:
0.6032 = 60.32% probability that on a given day the supermarket will sell between 477 and 525 gallons of milk
Step-by-step explanation:
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.
Mean and standard deviation of 486.9 and 24.01, respectively.
This means that [tex]\mu = 486.9, \sigma = 24.01[/tex]
What is the probability that on a given day the supermarket will sell between 477 and 525 gallons of milk?
This is the p-value of Z when X = 525 subtracted by the p-value of Z when X = 477.
X = 525
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{525 - 486.9}{24.01}[/tex]
[tex]Z = 1.59[/tex]
[tex]Z = 1.59[/tex] has a p-value of 0.9441
X = 477
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{477 - 486.9}{24.01}[/tex]
[tex]Z = -0.41[/tex]
[tex]Z = -0.41[/tex] has a p-value of 0.3409
0.9441 - 0.3409 = 0.6032
0.6032 = 60.32% probability that on a given day the supermarket will sell between 477 and 525 gallons of milk

Area = L*W
L = 4
W = 2
Area = 4 * 2 = 8
But there are two of them (2 * 8) 16
Left and right
Area = L * W
L = 3
W = 2
Area = 2 *3 = 6
But there are two of them 12
From back
L*W = 4*3
But there are two of them 24
Total 52
If x varies inversely as y and x = 24 when y = 4, find x when y = 12.
