We are given that in a marketing survey, a random sample of 730 women shoppers revealed that 628 remained loyal to their favorite supermarket during the past year (i.e. did not switch stores).

Let p = proportion of all women shoppers who remain loyal to their favorite supermarket

Now, the point estimate for the population proportion (p) is represented by ;

Point estimate for p = $\hat p$ = $\frac{X}{n}$

where, X = Number of women shoppers who remained loyal to their favorite supermarket during the past year = 628

n = sample of women shoppers = 730

So, point estimate for p ( $\hat p$ ) = $\frac{X}{n}$

= $\frac{628}{730}$ = 0.86

Which equation, when graphed, has x-intercepts at (8,0) and (-2, 0) and a y-intercept at (0, -48)?

n200080 [17]

Answer:

f(x)=-3(x-8)(x+2)

Step-by-step explanation:

f(8)=-3(8-8)(8+2)=-3×0×10=0

f(-2)=-3(-2-8)(-2+2)=-3×(-10)×0=0

f(0)=-3×(0+8)×(0+2)=-3×8×2=-48
