formula is pi*r*(r+sqaureroot(h^2+r^2)
plug in the numbers and the calculated area is 1507.96
but since you cant use fraction or decimals
the answer should be 480PI
Answer:
684 mm squared
Step-by-step explanation:
Very simple. It's 18mm multiplied by 38 mm.
18 mm * 38 mm = 684 mm2
Using the normal distribution, there is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
For this problem, these parameters are given as follows:

A sum of 7100 is equivalent to a sample mean of 7100/40 = 177.5, which means that the probability is the <u>p-value of Z when X = 177.5</u>, hence:

By the Central Limit Theorem:


Z = -0.79
Z = -0.79 has a p-value of 0.2148.
There is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.

The first question would be A and Cis the answer for the second question!!
Answer:
The slope is -3/8
Step-by-step explanation:
(6,−6);(−18,3)
(x1,y1)=(6,−6)
(x2,y2)=(−18,3)
Use the slope formula:
m=
y2−y1
/x2−x1
3−−6
/−18−6
