What are the zeros of f(x) = x(x – 8)?

1 answer:

5 0

F(x) will = 0 when either x = 0 or x = 8. Here's how you know.
if x = 0 then 0 * (x - 8) = 0 because anything multiplied by 0 is zero.

if x = 8 then 8 * (8 - 8) = 8 * 0 = 0

One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged pengui

Oksana_A [137]

Answer: 90% confidence interval would be $(-0.2483,-0.0717)$

Step-by-step explanation:

Since we have given that

n₁ = 50

Number of metal tagged penguins survived = 10

So, $p_m=\dfrac{10}{50}=0.2$

n₂ = 50

Number of electronic tagged penguins = 18

So, $p_e=\dfrac{18}{50}=0.36$

So, at 90% confidence interval, z = 1.28

So, interval would be

$(p_m-p_e)\pm z\sqrt{\dfrac{p_m(1-p_m)}{n}+\dfrac{p_e(1-p_e)}{n}}\\\\=(0.2-0.36)\pm 1.28\sqrt{\dfrac{0.2\times 0.8}{50}+\dfrac{0.36\times 0.64}{50}}\\\\=-0.16\pm 0.0883\\\\=(-0.16-0.0883,-0.16+0.0883)\\\\=(-0.2483,-0.0717)$

Hence, 90% confidence interval would be

$(-0.2483,-0.0717)$

lesya692 [45]

Answer: everyone gets 1/4 of the pizza.

Step-by-step explanation: you can convert the 3/4 to .75 and divide that by 3. or you can think about it as the pizza is a dollar and the slices are quarters/ 25 cents. OOOO those are your 4 quarters that make up a dollar/ pizza. OOO those are the 3/4 of the pizza left. if there are 3 people each gets a quarter/ fourth of a pizza. so the answer is 1/4.

Answer:

6 =h

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

12 = 1/2 (4) h

12 =2h

Divide each side by 2

12/2 = 2h/2

6 =h
