Pew Research Center is a nonpartisan polling organization that provides information about issues, attitudes, and trends shaping

jarptica [38.1K]

Answer:

47% of American adult population

Step-by-step explanation:

The reason why polls are carried out is to obtain information that can represent the opinions, status or habits of the population. The polls do not include the total population, then include a small number of participants, but the results are extrapolated to the general population. There are always small margins of error resulting from polls, that is why the confidence levels are usually +/- 3 or 4%.

Evaluate the given equation for the indicated function values. pls help

Xelga [282]

Answer:

The answer in each numeral is:

f(4) = 28
f(10) = -19
f(-5) = -33
f(9) = -9

Step-by-step explanation:

To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:

1. f(n) = 5n + 8
f(4) = ?

As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:

1. f(4) = 5*(4) + 8
f(4) = 20 + 8
f(4) = 28

The first answer is 28, now we'll continue with the next exercises:

2. f(n) = -2n + 1
f(10) = -2*(10) + 1
f(10) = -20 + 1
f(10) = -19

3. f(n) = 6n - 3
f(-5) = 6*(-5) - 3
f(-5) = -30 - 3
f(-5) = -33

4. f(n) = -n
f(9) = -9

In this form, you can prove the answers are: 28, -19, -33, and -9 respectively.

Solve for the missing variable.

yan [13]

Answer:

x ≈ 6.3
y ≈ 7.7
z ≈ 4.9

Step-by-step explanation:

In this geometry, there are three "geometric mean" relations that apply. They can be summarized by the rule ...

a segment touching the hypotenuse is equal to the geometric mean of the segments of the hypotenuse it touches.

For x and y, the two segments will be the short one (4 or 6, respectively) and the entire hypotenuse (4+6=10).

Using this rule, we have ...

x = √(4·10) ≈ 6.3

y = √(6·10) ≈ 7.7

z = √(4·6) ≈ 4.9

__

The geometric mean of two numbers is the square root of their product.

_____

Additional comment

These relations come about because all of the right triangles in this figure are similar. That means corresponding sides are proportional.

x/10 = 4/x ⇒ x² = 40

y/10 = 6/y ⇒ y² = 60

z/6 = 4/z ⇒ z² = 24
