Answer:

4.6

Step-by-step explanation:

Allow me to revise your question and hope it will be the same as the original one:

<em>In a certain town 22% of voters favor a given ballot measure for groups of 21 voters find the variance for the number who favor the measure</em>

<em>a. 1.9 </em>

<em>b. 13 </em>

<em>c. 4.6 </em>

<em>d. 3.6</em>

Here is my answer:

Given:

  • 22% of voters favor a given ballot = 0.22
  • Groups of 21 voters

So the variance is: 21*0.22 = 4.6

We choose B

Fourteen less children’s meals were served than adult meals at a barbecue. Children plate were 1.50 each and adult plates were 2
Annette [7]

Answer:

134 children and 120 adult plates were served

Step-by-step explanation:

let the children mean be x

Let the adult meal be y

If fourteen less children’s meals were served than adult meals at a barbecue, then;

y = x - 14 .... 1

IF Children plate were 1.50 each and adult plates were 2.00 each with a total of 441 in amount then;

1.5x + 2y = 441 .... 2

Substitute 1 into 2;

1.5x + 2(x-14) = 441

1.5x+2x-28 = 441

3.5x = 441+28

3.5x = 469

x = 469/3.5

x = 134

Recall that y = x - 14

y = 134-14

y = 120

Hence 134 children and 120 adult plates were served

Insert one term between -13 and -119 to create an arithmetic sequence of three terms.
daser333 [38]

Answer:

-66

Step-by-step explanation:

- 13, ____, -119

first, find the common difference:

-13 - (-119) = 106

next, divide 106 by 2: \frac{106}{2} = 53

so, the common difference is 53.

now, subtract 53 from -13:

-13 - 53 = -66

What are all of the x-intercepts of the continuous function in the table? (0, 8) (–4, 0) (–4, 0), (4, 0) (–4, 0), (0, 8), (4, an
crimeas [40]

Answer:

The  x-intercepts of the continuous function in the table are:

(-4,0) and (4,0).

Step-by-step explanation:

We are given a table of values of the continuous functions as:

(0, 8) (–4, 0) (–4, 0), (4, 0)

The x-intercept of a function is a point on the x-axis i.e. where y=0. (i.e. The x-intercept is where a line crosses the x-axis ).

Here y=f(x).

Hence from the given set of values we have:

f(x)=0 when x= -4 and x=4.

Since we are given the points as (-4,0) and (4,0).

Hence, the x-intercepts of the function f(x) is: (-4,0) and (4,0).
