What is the slope of the line below? Be sure to scroll down first to see all
answer options.
(-14,3) (2,-5)
Answer:
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)
A school sold 51 less children’s tickets than adult tickets for the school play. Adult tickets cost $1.25 and children’s tickets cost $0.75. A total of $129.75 was taken in. How many of each kind were sold? Show work pls
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:
(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

In a study by Peter D. Hart Research Associates for the Nasdaq Stock Market, it was determined that 20% of all stock investors are retired people. In addition, 40% of all U.S. adults invest in mutual funds. Suppose a random sample of 25 stock investors is taken. a. What is the probability that exactly seven are retired people
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.
The principal of a high school e-mails a survey to all parents asking them to vote on the best time to have the PTA meeting. She only receives responses from 56% of the parents. Describe how the design of the survey leads to bias.
A. 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.
B. A nonresponse error was made in this design. This type of sampling only represents the parents at this school and not the entire population.
C. A convenience sample error was made in this design. This type of sampling only represents the parents with e-mail addresses and not the entire population.
D. An undercoverage error was made in this design. This type of sampling only represents the parents in the city and not the entire population.
E. There are no potential areas of bias.
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.

A storage box in the garage is 3 feet tall, 4 feet long and has a volume of 9 cubic feet. How many square feet is the area of the base of the box?
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
A block of land was available for sale last year at $35,000.
a) if the inflation rate during the year was 3.2%, what would be the value of the land in this year?
b)if the inflation rate this year is reduced 2.7%, what price would the land attract next year??
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.

Triangle Theorems, Help!!!
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
y = x2+6x+8 and y = (x+2)(x+4) both define the same quadratic function. Without graphing, identify the x- and y-intercepts of the graph.
Put each of the intercepts in the form of an ordered pair ( . ) ( . ).
You should have three ordered pairs in your answer. Two x-intercepts and one y-intercept.
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.
The x-intercepts are: (-2,0) and (-4,0)The y intercept is (0,8)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)
