Solve for y (change the equation to slope-intercept form.
2y = 2x + 8. Divide each term by 2
y = x + 4.
So slope is 1
Answer:

Step-by-step explanation:
Let x be the cost of a coat and y be the cost of the shoes.
We have been given that Taka bought a new coat and new shoes, so the cost of new coat and shoes will be x+y.
We are also told that Taka spent $122 on both items. As Taka had spend $122, so the cost of coat and shoes will be greater than or equal to 122.
We can represent this information in an inequality as:

Therefore, the inequality
represents our desired solution.
Answer:
28495.5 ft
Step-by-step explanation:
V=(4
/3)π(r^2)
r=radius=diameter/2
165/2=82.5
(4/3)3.14(82.5^2)
(4/3) x3.14x6806.25=28495.5ft
Answer:

Step-by-step explanation:
A set of normally distributed data has a mean of 3.2 and a standard deviation of 0.7. Find the probability of randomly selecting 30 values and obtaining an average greater than 3.6.
We can denote the population mean with the symbol 
According to the information given, the data have a population mean:
.
The standard deviation of the data is:
.
Then, from the data, a sample of size
is taken.
We want to obtain the probability that the sample mean is greater than 3.6
If we call
to the sample mean then, we seek to find:

To find this probability we find the Z statistic.

Where:
Where
is the standard deviation of the sample



Then:

The probability sought is: 
When looking in the standard normal probability tables for right tail we obtain:
