Not completely sure what graph you are looking for but here is what I got, (-2,-15/4) hope this helps!
Answer:
Part A: a. the point 3 units to the left of 7
Part B: b. -4
Step-by-step explanation:
Part A: The expression can be simplified into 7 - 3, and when you subtract a number, you go left on the number line, so the point 3 left of 7
Part B: 7 - 3 = 4, and to get to 0 from 4, you need to subtract 4 or add -4
C, planes are more likely to take off on time. .72 as a percent is 72%. Hence, a relatively high probability that the planes will take of on time.
Answer:
The answer would be A
Step-by-step explanation:
a. the pumpkins maximum height is 204.06 feet and it hits the ground after 7.01 seconds.
Answer: (D) 16%
Step-by-step explanation:
Binomial probability formula :-
, where n is the sample size , p is population proportion and P(x) is the probability of getting success in x trial.
Given : The proportion of students in College are near-sighted : p= 0.28
Sample size : n= 20
Then, the the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is given by :_
![P(x=4)=^{20}C_4(0.28)^4(1-0.28)^{20-4}\\\\=\dfrac{20!}{4!16!}(0.28)^4(0.72)^{16}\\\\=0.155326604912\approx0.16\%](https://tex.z-dn.net/?f=P%28x%3D4%29%3D%5E%7B20%7DC_4%280.28%29%5E4%281-0.28%29%5E%7B20-4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B20%21%7D%7B4%2116%21%7D%280.28%29%5E4%280.72%29%5E%7B16%7D%5C%5C%5C%5C%3D0.155326604912%5Capprox0.16%5C%25)
Hence, the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is closest to 16%.
