A random sample of 1,175 people in a certain country were asked whether they thought climate change was a problem. The sample pr

il63 [147K]

Answer: c. We are 95 percent confident that the proportion of people in the sample who think climate change is a problem is between 0.146 and 0.214.

Step-by-step explanation:

Interpretation for 95% confidence interval :

A person can be 95% confident that the true population parameter lies in it.

By considering the given information , we have

population parameter→ p (Proportion of people who think climate change )

95 percent confidence interval = (0.146, 0.214)

Interpretation : We can be 95% confident that the true population proportion of people who think climate change lies between 0.146 and 0.214.

So , the correct answer is

c. We are 95 percent confident that the proportion of people in the sample who think climate change is a problem is between 0.146 and 0.214.

Given x² - 16x + 4 = 0:

arsen [322]

PART A
General formula of quadratic equation
ax² + bx + c = 0
To find the discriminant of the quadratic equation shown above, use this following formula.
d = $\sqrt{b^{2}-4ac}$

There is a quadratic equation below
x² - 16x + 4 = 0
therefore
a = 1
b = -16
c = 4

Plug in the numbers to the formula
d = $\sqrt{b^{2}-4ac}$
d = $\sqrt{(-16)^{2}-4(1)(4)}$
d = $\sqrt{(256-16}$
d = $\sqrt{240}$

Simplify
d = $\sqrt{16*15}$
d = $4 \sqrt{15}$
The value of the discriminant is 4√15

PART B
If the discriminant is less than zero (negative), the quadratic equation has imaginary solution.
If the discriminant is equal to zero, the quadratic equation has only one solution.
If the discriminant is more than zero (positive), the quadratic equation has two real solutions.

Because the discriminant of the quadratic equation is 4√15 and it's positive, <u>the quadratic equation has two real solutions.</u>
