The answer would be 73.(3)
-9.3 is bigger if you put the fraction into a decimal it is smaller then the -9.2
Answer: 140
Step-by-step explanation:
Given t = 5 snd q = 4, tq = 5x4= 20
7tq will be: multiply the value of tq by 7
=7× 5×4
7 × 20 = 140
I hope this is clear.
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
Slope = change in y / change in x
= (15 - 9) / (7 - 5)
= 6 / 2
= 3
