The heights of the students in a class are (in inches) 60, 72, 56, 57, 74, 61, 64, 63, 66, 56, 72, 72, 71, 74, 61

Answer:
There is a 11% chance that someone 5 foot 6 inches would get chosen.
Step-by-step explanation:
5*12=60
60+6=66
there are 19 numbers
66/19=.105263
you would then round up the tenths place due to the value of the thousandths place being above 5.
Eq1) 2r+2s=50
eq2) 2r-s=17
solve for s in equation2 (eq2)
-s=17-2r
s=-17+2r
Substitute s into equation1 (eq1)
2r+2(-17+2r)=50
2r-34+4r=50
6r-34=50
6r=50+34
6r=84
r=14
Substitute into either equation and solve for s
2(14)-s=17
28-s=17
-s=17-28
-s=-11
s=11
Answer:
254.34 miles²
Step-by-step explanation:
How do we find the area of a circle?
- The area of a circle can be found using πr², where r = radius. We have the radius as 9 miles, and pi is shortened to 3.14.
<u>Solving</u>
Therefore, the area is 254.34 miles².

Answer:
0.05
Step-by-step explanation:
P value that is less than 0.05, that is P < 0.05 means that the null hypothesis is false and should be rejected. If the P value is greater than 0.05, that is P > 0.05, it means the null hypothesis is true. The P value is also called the calculated probability value. P value subtracted from 1 is the probability that the alternative hypothesis is true.
The slope should be -1 and the y intercept is 3
