The probability is 0.2 that a person shopping at a certain store will spend less than $20. For groups of size 17, find the mean number who spend less than $20.
1 answer:
Steps:
1: p=0.2
2: n = 17
3: n*p= 17*0.2=3.4
Description:
The person will spend less than 20 or o.2 as seen in the question. Meaning p will equal 0.2. P for probability. Now n is for number. n will equal 17. And then we have to times all the number. N times P will equal 17 then times it by 0.2= Answer will come as 3.4.
Answer: 3.4

Answer:
Step-by-step explanation:
<u>We see that:</u>
y- intercept is b = 0.5, point (0, 0.5) Rate of change is m = 1 as each next value of y is greater by 1. <u>The function is:</u>
Correct choice is A
Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25
