Answer:
Step-by-step explanation:
mean diameter = 206
variance = 6.25
standard deviation = √ variance
σ = √ 6.25 = 2.5
sample size n = 90
z = deviation from mean / (σ / √n)
= 0.3 / (2.5/ √90)
= .3 / .2635
= 1.1385
P value from the table = (.87 - .5 ) x 2
= .37 x 2 .
or 74 % .

Answer: b = 1850 - 120w
Step-by-step explanation:
Let w represent the number of weeks for which the books are purchased.
They are being purchased at a steady rate of 120 books per week. This means that the number of books purchased after w weeks would be 120w.
The total number of algebra textbooks that she had initially is 1850
If b represents the number of books left after w-weeks of sales, then the linear function that models the number of books left after w weeks would be
b = 1850 - 120w
What exactly do you mean by *? Like exponent? If so the domain is R= −∞,∞ with its range being [−1,1]. If this wasn’t meant by exponent, please comment and I’ll reply ASAP!
