What are the zeros of the polynomial function f(x) =x^2+5x-6

Alborosie

Answer:

The zeros are x=1, x=-6

Step-by-step explanation:

f(x) =x^2+5x-6

Factor: What two numbers multiply to -6 and add to 5

-1 *6 = -6

-1 +6 = 5

f(x) = (x-1) (x+6)

Using the zero product property

0 = (x-1) (x+6)

x-1 =0 x+6=0

x=1 x=-6

The zeros are x=1, x=-6

15.) A market

kumpel [21]

Answer: $p=0.610$

Step-by-step explanation:

Given : A market research worker interviewed a random sample of 18 people about their use of a certain product.

The results, in terms of Yes (Y) or No (N) are as follows:

Y-N-N-Y-Y-Y-N-Y-N-Y-Y-Y-N-Y-N-Y-Y-N.

The number of people said "Yes" for the product= 11

Then, the sample proportion for the users of the product = $\hat{p}=\dfrac{11}{18}0.611111111111\approx0.61$

We know that the sample proportion is the best estimate for the population proportion.

Thus the point estimate for population proportion : $p=\hat{p}=0.610$
