Answer:

x = 8

Step-by-step explanation:

(6x + 7)° + 45° = (13x - 4)° => exterior angle theorem of a triangle

6x + 7 + 45 = 13x - 4

6x + 52 = 13x - 4

Collect like terms

6x - 13x = -52 - 4

-7x = -56

Divide both sides by -7

x = -56/-7

x = 8

Step-by-step explanation:

The slope of a line can be determined by any two points on the line and is defined as

m=(y2-y1)/(x2-x1),

We are given points (-14,3) and (2,-5) so

m=(-5-3)/(2-(-14))

m=(-8)/(16)

m= -1/2. (Answer F)

Answer:

A

Step-by-step explanation:

The design of the survey leads to bias because a nonresponse error was made in this design. This type of sampling only represents those who answered the survey; it does not represent the entire population.

Only 56% of response were received this means the entire population did not participate in the survey only a chuck of them answered the survey. This can lead to a biased result, an assumption.

Answer:

3 ft^2

Step-by-step explanation:

first find the width of the storage box using the given volume

V = L * W * H

9 = 4 * W * 3

9 = 12 * W

9/12 = W

W = 3/4 or .75

then with that to find the are of the base multiply the length and the width

a = l * w

a = 4 * 3/4

a = 3

Answer:

x-int:(-2,0)(-4,0) . y-int:(0,8)

Step-by-step explanation:

y = x2+6x+8 and y = (x+2)(x+4)

x-int:

x+2=0

x= -2

(-2,0)

x-int:

x+4=0

x=-4

(-4,0)

y-int: plug 0 for x

y=(0+2)(0+4)

y=8

(0,8)

The intercepts of a graph are the points where the graph crosses the x or y axes.

Given that:

[tex]y = x^2 + 6x + 8[/tex]

[tex]y = (x + 2)(x + 4)[/tex]

The x-intercepts

This is when [tex]y = 0[/tex]

So, we have:

[tex]y = (x + 2)(x + 4)[/tex]

[tex](x + 2)(x + 4) = 0[/tex]

Split

[tex](x + 2) = 0[/tex] or [tex](x + 4) = 0[/tex]

Solve for x

[tex]x = -2[/tex] or [tex]x = -4[/tex]

Hence, the x-intercepts are: (-2,0) and (-4,0)

The y-intercepts

This is when [tex]x = 0[/tex]

So, we have:

[tex]y = x^2 + 6x + 8[/tex]

Substitute 0 for x

[tex]y = 0^2 + 6 \times 0 + 8[/tex]

[tex]y = 8[/tex]

Hence, the y intercept is (0,8)

Answer:

0.0545 = 5.45% probability that exactly seven are retired people.

Step-by-step explanation:

For each stock investor, there are only two possible outcomes. Either they are retired people, or they are not. Stock investors are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

20% of all stock investors are retired people.

This means that [tex]p = 0.2[/tex]

a. What is the probability that exactly seven are retired people?

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 7) = C_{20,7}.(0.2)^{7}.(0.8)^{13} = 0.0545[/tex]

0.0545 = 5.45% probability that exactly seven are retired people.

Answer:

- $36,120

- $35,945

Step-by-step explanation:

This problem is rather pretty simple when breaking it down. We really just need to ask ourselves what the percent is of our whole and then add that to our total. Work shown below.

Step 1:

Move decimal over on both. You should get...

.032 and .027

(You always move it two to the left in these types of cases.)

Step 2:

Multiply our original price by inflation decimal. You should get...

$35,000 x .032 = $1,120

$35,000 x .027 = $945

Step 3:

Add our previous answer to our original price. You should get...

$35,000 + $1,120 = $36,120

$35,000 + $945 = $35,945

- This is our final answer, as the pricing increased due to inflation.

Note: Inflation means their is an increase in price.

Answer:

  (b)  x = 7, AB = 9, AC = 12

Step-by-step explanation:

ΔAEB ~ ΔCDB so corresponding sides are proportional.

  AB/CB = AE/CD

  (x+2)/(x -4) = 12/4

  x +2 = 3(x -4) . . . . . . multiply by x-4

  x +2 = 3x -12 . . . . . . eliminate parentheses

  14 = 2x . . . . . . . . . . . add 12-x

  7 = x . . . . . . . . . . . . . divide by 2

AB = x +2 = 7 +2 = 9

BC = x -4 = 7 -4 = 3

AC = AB +BC = 9 +3 = 12

__

In summary, ...

  x = 7, AB = 9, AC = 12 . . . . . matches the 2nd choice

Additional comment

Please note the other choices make no sense.

  (a) AB = x +2 = -5 +2 = -3 ≠ -9

  (c) AC = 2x-2 = 2(7) -2 = 12 ≠ 9

Answer:

84 adult tickets and 33 child tickets were sold.

Step-by-step explanation:

Given that a school sold 51 less children's tickets than adult tickets for the school play, and adult tickets cost $ 1.25 and children's tickets cost $ 0.75, and a total of $ 129.75 was taken in, to determine how many of each kind were sold the following calculations must be done:

61 x 1.25 + 10 x 0.75 = 83.75

81 x 1.25 + 30 x 0.75 = 123.75

82 x 1.25 + 31 x 0.75 = 125.75

83 x 1.25 + 32 x 0.75 = 127.75

84 x 1.25 + 33 x 0.75 = 129.75

Thus, 84 adult tickets and 33 child tickets were sold.

Answer:

There were 80 adult tickets sold and 29 children tickets sold.

c + 51 = a

51 = a - c

c = a - 51

a*1.25 + c*0.75 = 129.75

a = 100  c = 49  a + c = 161.75

a = 80  c = 29  a + c = 121.75

Answer:

[tex]Domain = \{7,1,8,d\}[/tex]

Step-by-step explanation:

Given

Required

The domain and the range

A function represented as:

[tex]Function = \{(x_1,y_1),(x_2,y_2)......(x_n,y_n)\}[/tex]

Where:

[tex]Domain=x_1,x_2,....,x_n[/tex]

[tex]Range=y_1,y_2,....,y_n[/tex]

So:

[tex]G=\{(7, d), (1, a), (8,8), (d, 0)\}[/tex]

[tex]Domain = \{7,1,8,d\}[/tex]

[tex]Range = \{d,a,8,0\}[/tex]
