what is the slope of the line below? If necessary, enter your answer as a fraction in lowest terms, using the slash as the fraction bar. Do not enter your answer as a decimal number or an equation. (-2, - 3) (-4, - 9)
Answers
Answer:
The slope is 3
Step-by-step explanation:
The slope is 3 because when you set up the equation (-2,-3) is labeled as x1 and y1 and (-4,-9) is labeled as x2 and y2. When you set up the equation you get -9--3 / -4--2, which becomes -6/ -2, which then becomes -3/-3, which is really just 3. :)
The slope of the line given is 3.
What is a slope of a line?Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
Given is a line passing through points (-2, -3) (-4, -9), we need to find its slope,
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:-
y₂-y₁ / x₂-x₁
Here, (x₁, y₁) and (x₂, y₂) are (-2, -3) (-4, -9)
So, the slope is = -9+3 / -4+2 = -6 / -2 = 3
Hence, the slope of the line given is 3.

Sheryl and Jennifer were given the same number of sticker at first.After jennifer used 84 stickers ,sherly had 4 times as many stickers as jennifer. How many stickers were given to sherly at first
Answers
Answer:
112 stickers
Step-by-step explanation:
Let x and y represent the number of stickers Sheryl and Jennifer were given at first.
Sheryl and Jennifer were given the same number of sticker at first.
So;
x = y ......1
After jennifer used 84 stickers ,sherly had 4 times as many stickers as jennifer.
x = 4(y-84)
x = 4y - 336 ......2
Substituting equation 1 into 2
y = 4y - 336
Solving for y;
4y - y = 336
3y = 336
y = 336/3
y = 112
Therefore, sherly was given 112 stickers at first

A local charity organization held an event to celebrate its work for the past five years. A local newspaper reporter who attended the event asked 75 of the attendees about their contributions. The reporter computed the mean amount of money raised by the 75 attendees to be $18,500. In an article published by the local newspaper, the reporter was quoted as stating, "The members of the charity organization were successful in raising money for their cause. Last year, they raised a mean amount of $18,500!"
Part A: What is a statistical advantage of using the median of the reported amounts, rather than the mean, as the estimate of the typical amount raised? (4 points)
Part B: The newspaper editor felt the individuals who attended the event may be different from the organization as a whole. A more detailed survey of the members was planned to determine a better estimate of the amount of money raised. The staff developed two methods based on the available funds to carry out the survey.
Method 1: Send out an e-mail to all 10,530 members of the organization and ask them to complete an online form. The staff estimates at least 2,000 members will respond.
Method 2: Select a simple random sample of members of the organization and contact the selected members directly by phone. Follow up to ensure all responses are obtained. Because method 2 requires more time than method 1, the staff estimates that only 1,000 members of the organization can be contacted using method 2.
Which of the two methods would you select for estimating the average yearly amount raised by all 10,530 members of the charity organization? Explain your reasoning by comparing the two methods and by describing the effect of each method on the estimate.
Answers
Answer:
Part A. The statistical advantage of using the median is that the median is less effected by skewed data and outliers.
Part B. I would select method two because method one has a non-response bias and the sample individuals are not selected at random.
Step-by-step explanation:
Higher values pull averages up where medians just select the middle value and aren't necessarily pulled by outliers.
Non response biases happen when the individuals chosen choose not to answer or can volunteer to answer.
Sending out emails to everyone at the org is not choosing them at random.
A statistical advantage of using the median instead of the mean as the estimate of the typical amount raised is that the median is less sensitive to extreme values or outliers.
Method 1 would be the better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
Part A:
A statistical advantage of using the median instead of the mean as the estimate of the typical amount raised is that the median is less sensitive to extreme values or outliers.
In this case,
If there were a few attendees who contributed a very large amount of money, it would increase the mean and make it an overestimate of the typical amount raised.
However, the median would not be affected by the outliers, and it would give a better estimate of the typical amount raised by the majority of the attendees.
Part B:
Method 1 would be a better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization.
This is because it would have a larger sample size than method 2, which would make the estimate more precise and reduce the sampling error.
Additionally,
Method 1 would include a broader range of members, including those who may not have attended the event or who may have contributed in other ways besides donating money.
Method 2, on the other hand, would have a smaller sample size and would only include a random subset of the organization's members, which could lead to sampling bias if the selected members are not representative of the larger population.
Furthermore, the follow-up required by method 2 would make it more time-consuming and potentially less cost-effective than method 1.
Thus,
Method 1 would be the better choice for estimating the average yearly amount raised by all 10,530 members of the charity organization because it would have a larger sample size, include a broader range of members, and be more cost-effective than method 2.

The area of a garden is 30 square feet. The perimeter is 26 feet. What are the measurements of each side?
Please help this question is fustrating
Answers
Answer: 3 feet by 10 feet rectangle
===========================================================
Explanation:
Assuming this garden is a rectangle, it has dimensions L and W which are the length and width respectively.
perimeter of rectangle = 2*(length+width)
P = 2*(L+W)
26 = 2(L+W) ... plug in given perimeter
26/2 = L+W .... divide both sides by 2
13 = L+W
13-W = L .... isolate L by subtracting W from both sides
L = 13-W
------
Area of rectangle = Length*Width
A = L*W
A = (13-W)W .... replace L with 13-W
A = W(13-W)
A = 13W - W^2 ..... distribution
30 = 13W - W^2 .... plug in given area A = 30
W^2 - 13W + 30 = 0 ... get everything to one side
(W - 10)(W - 3) = 0 ...... factor
W-10 = 0 or W-3 = 0 ...... zero product property
W = 10 or W = 3
----------
If the width is W = 10, then
L = 13-W
L = 13-10
L = 3 is the length
Or if the width is W = 3, then
L = 13-W
L = 13-3
L = 10 is the length
Either way, this is a 3 ft by 10 ft rectangle
--------
Check:
Area = length*width = 10*3 = 30 square feet
perimeter = 2(length+width) = 2*(10+3) = 2*13 = 26 feet
or you could say
perimeter = L+W+L+W = 10+3+10+3 = 13+13 = 26 feet
we get the correct area and perimeter, so this confirms our answer.

Please answer me<br />bis two fifths of c.<br />4a = 30<br />Work out the ratio a:b:c<br />Give your answer in its simplest form where a, b and c are integers.
Answers
b is two fifths of c, so we make this a ratio with c = 1.
The ratio of b:c is 2/5 : 1
We also have 4a = 3c, rewrite this ratio so c is 1 by dividing both sides by 4,
so we get the ratio of a to c as 3/4 : 1
Now we get the a:b:c ratio of 3/4 : 2/5 : 1 now we can change the fractions to whole numbers, first by multiplying the 3 numbers by 4 to get get rid of the denominator of 4 in a:
3 : 8/5 : 4
Now multiply the 3 numbers by 5 to remove the denominator of 5 in b:
15 : 8 : 20
Now we can check using the equations:
b is 2/5 of c: 20 x 2/5 = 40/5 = 8 This is true.
4a = 3c: 4(15) = 3(20) = 60 = 60, this is also true.
The ratios is 15 : 8: 20

Express the system in standard form:
{3 x + y = 12 | (equation 1)
-(7 x) + 4 y = 10 | (equation 2)
Swap equation 1 with equation 2:
{-(7 x) + 4 y = 10 | (equation 1)

D. 1, 1/3, 1/9
Answers
Answer:
B. 6/5, 12/25, 24/125Step-by-step explanation:
Let the geometric means to be inserted be x, y and z. The geometric series will contain 5 terms as shown:
3, x, y, z, 48/625
Using the nth term of a geometric sequence to find the missing term.
[tex]Tn = ar^{n-1}[/tex] where:
a is the first term
n is the number of terms and
r is the common ratio
From the sequence, a = 3
[tex]T5 = 3r^{5-1} \\T5 = 3r^{4}[/tex]
Since the fifth term is 48/625 then:
[tex]3r^{4}=\frac{48}{625} \\r^{4}= \frac{48}{625*3} \\r^{4} = \frac{16}{625} \\r=\sqrt[4]{\frac{16}{625} } \\r = \frac{2}{5}[/tex]
To get the 2nd, 3rd and 4th term, we will substitute the value of the first term and the common ratio in the equation given.
[tex]T2 = 3(\frac{2}{5} )^{2-1}\\ T2 = 3*2/5\\T2 = 6/5[/tex]
when n = 3;
[tex]T3 = 3(\frac{2}{5} )^{3-1}\\ T3 = 3*(\frac{2}{5} )^{2} \\T3= 3*4/25\\T3 = 12/25[/tex]
when n = 4;
[tex]T4 = 3(\frac{2}{5} )^{4-1}\\ T4 = 3*(\frac{2}{5} )^{3} \\T4= 3*8/125\\T4 = 24/125[/tex]

Rectangular pizza,
[tex]area = length \times width[/tex]
Let length = 8 inches,
Let width = 16 inches,
[tex]area = 8 \times 16[/tex]
[tex]area = 128 \: \: {inches}^{2} [/tex]
Circular pizza,
[tex]area = \pi \times {r}^{2} [/tex]
Let r = 5 inches,
