Answer:

a) x-intercepts are (0,0) and (5,0)

b) 6.25 yards

Step-by-step explanation:

a) x intercepts are:

-x² + 5x = 0

-x(x - 5) = 0

x = 0, 5

b) -x² + 5x

-(x² - 5x)

-[x² - 2(x)(5/2) + (5/2)² - (5/2)²]

-(x - 5/2)² + 25/4

Max height is:

25/4 yards or 6.25 yards

The cost of 5 gallons of ice cream has a standard deviation of 7 dollars with a mean of 25 dollars during the summer. What is th
victus00 [196]

Answer:

0.000221

Step-by-step explanation:

Using the z score formula when a random number of samples is given =

z = (x-μ)/σ/√n, where

x is the raw score

μ is the population mean

σ is the population standard deviation = 7

n is random number of samples = 83

Note that:2.2 dollars = x-μ

z = 2.2/7/√8.3

z = 3.51402

Probability value from Z-Table:

P(x<27.7) = 0.99978

P(x>27.7) = 1 - P(x<27.7) = 0.00022069

Approximately = 0.000221

Hence, the probability that the sample mean would differ from the true mean by greater than 2.2 dollars if a sample of 83 5-gallon pails is randomly selected is 0.000221

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?
8_murik_8 [283]

The inverse of the given function is y = √5x + 7/2 - 3

<h3>Inverse of a function</h3>

Given the function expressed below;

5y + 4 = (x+3)² +1/2

5y = (x+3)² - 7/2

y = 1/5(x+3)² - 7/10

Replace y as x

x = 1/5(y+3)² - 7/10

Make y the subject of the formula

5x = (y+3)²- 7/2

(y+3)² = 5x + 7/2

y+3 = √5x + 7/2

y = √5x + 7/2 - 3

Hence the inverse of the given function is y = √5x + 7/2 - 3
