F(x)=-3|x-4| Vertical shrink by a factor of 1/2
sweet [91]

to vertically shrink a function by a factor of c, multiply the whole function by c

f(x) vertically shrunk by a factor of c would be cf(x)

so f(x)=-3|x-4| vertically shrunk by a factor of 1/2 would be f(x)=(\frac{-3}{2})|x-4|

The perimeter of a rectangle is 54 cm. Find its length and width if the length is represented
Anna71 [15]

Answer:

length = 20

width = 7

Step-by-step explanation:

Perimeter of a rectangle is

P = 2(l+w)

54 = 2( 3x+2 + 2x-5)

Combine like terms

54 = 2( 5x -3)

Divide each side by 2

54/2 = 5x-3

27 = 5x-3

Add 3 to each side

27+3 = 5x-3+3

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

3x+2 = 3(6)+2 = 18+2 = 20

2x-5 = 2(6)-2 =12-5 =7

Suppose that a company claims that its air fresheners last 19 days, on average. You take many large samples, and find, each time
spayn [35]
My answer would be B 19

19 days is what they claimed but the sample is outside of the 95% confidence interval so

19 x 95% = 19.95  

Below this value, 19.95 is the probable mean number of days that the company's air fresheners last. 15,17, and 19 can be the mean number of days.
