C and D because in that image that is what an proportional relationship looks like so anything that looks like the graph in the photo or c and d is proportional
38.2 is the quotient!!!!
Hope this helps
D = 5.5p + 25
D: dollars
P: people attending
Answer:
The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159
Step-by-step explanation:
According to the given data we have the following:
mean = μ= 22
standard deviation = σ = 2
n = 100
μx = 22
σx=σ/√n=2/√100=0.2
Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2
=P(z<-1)
= 0.159
The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159
Answer:
(-2,-11)
Step-by-step explanation:
3x-2(4x-3)=16
3x-8x+6=16
-5x=10
x=-2
Plug back in
y=4(-2)-3
y=-8-3
y=-11
