Question 1)
Answer:
The slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Step-by-step Explanation
Given the points
(-5, -20)(9, 9)Finding the slope between (-5, -20) and (9, 9)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-20\right),\:\left(x_2,\:y_2\right)=\left(9,\:9\right)[/tex]
[tex]m=\frac{9-\left(-20\right)}{9-\left(-5\right)}[/tex]
Refine
[tex]m=\frac{29}{14}[/tex]
Therefore, the slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Question 2
Answer:
the slope between (18, -5) and (18, 20) is undefined.
Step-by-step Explanation
Given the points
(18, -5)(18, 20)As the x-values of the points are the same. It indicates that the given line is vertical.
Finding the slope between (18, -5) and (18, 20)
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - (-5)] / [18 - 18]
= [20+5] / [0]
= 25/0
= ∞ or undefined
Thus, the slope between (18, -5) and (18, 20) is undefined. It indicates that the line is vertical.
Hence, the slope between (18, -5) and (18, 20) is undefined.

Q base and height of a parallelogram 12 cm and 8 cm respectively find its area....
please give me fast answer.
Answer:
The area of a parallelogram is: 96 cm²
Step-by-step explanation:
Given
The base of a parallelogram b = 12 cmThe height of a parallelogram h = 8 cmTo determine
The area of a parallelogram A = ?
Using the formula to calculate the area of a parallelogram
A = bh
here
b is the base of a parallelogram h is the height of a parallelogramso substituting b = 12 and h = 8 in the equation
A = bh
A = 12×8
A = 96 cm²
Therefore, the area of a parallelogram is: 96 cm²

Pencils are sold in boxes of 10. Erasers are sold in boxes of 14. A teacher wants to buy the same number of pencils and erasers. Work out the smallest number of boxes of each item she should buy.
Answer:
We have;
7 pencil boxes and 5 eraser boxes
Step-by-step explanation:
To find the smallest number of boxes that can be bought, what we simply do is to find the lowest common multiple of the content of each of the boxes
hence, we are going to find the lowest common multiple of 10 and 14
The lowest common multiple of 10 and 14 is 70
So the smallest number of pencil boxes that can be bought is 70/10 = 7
The smallest number of eraser boxes would be 70/14 = 5
At the dance, the ratio of the number of girls to boys is 7:5. If there are 36 more girls than boys, how many girls were at the dance? How many boys were at the dance?
9514 1404 393
Answer:
126 girls90 boysStep-by-step explanation:
The difference is 7-5 = 2 "ratio units", corresponding to a difference of 36 dancers. Then each "ratio unit" stands for 36/2 = 18 dancers.
There are 7×18 = 126 girls.
There are 5×18 = 90 boys.
_____
You could solve this by writing some equations:
g/b = 7/5
g -b = 36
Then you could substitute for g:
(36+b)/b = 7/5
36/b +1 = 2/5 +1 . . . . expand the fractions
36/b = 2/5 . . . . . . . . . subtract 1
b = (5/2)(36) = 90 . . . multiply by 5/2b
g = 36+90 = 126
Compute the standardized test statistic, χ 2, to test the claim σ 2 = 25.8 if n = 12, s 2 = 21.6, and α = 0.05.
Answer:
[tex]t^2=9.2[/tex]
Step-by-step explanation:
From the question we are told that
Standard Deviation [tex]\sigma=28.8[/tex]
Sample space [tex]n=12[/tex]
[tex]s^2= 21.6[/tex]
Generally the equation for test statistics is mathematically given by
[tex]t^2=frac{(n-1)*s^2}{\sigma^2}}[/tex]
[tex]t^2=\frac{(12-1)*21.6}{25.8}[/tex]
Therefore the standardized test statistics
[tex]t^2=9.2[/tex]

Answer:
when x = -1, y = -3
when x = -1, y = -1
when x = -1, y = 1
when x = -1, y = 3
Step-by-step explanation:
x = -1; plug in y = 2(-1) - 1 = -2 - 1 = -3
x = 0; plug in y = 2(0) - 1 = 0 - 1 = -1
x = 1; plug in y = 2(1) - 1 = 2 - 1 = 1
x = 2; plug in y = 2(2) - 1 = 4 - 1 = 3

Trey deposits $700 into an account that pays simple interest at a rate of 6% per year. How much interest will he be paid in the first 3 years?
Answer:
$1.26
Step-by-step explanation:
$700 times 0.06 times 3 = 126
126 divided 100 = 1.26
the formula of simple interest is
Amount times Rate times Time divided by 100
Trey deposits $700 into an account that pays simple interest at a rate of 6% per year. $1.26 interest he will be paid in the first 3 years.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.
Simple Interest = (Principal × Rate × Time) / 100
Trey deposits $700 into an account that pays simple interest at a rate of 6% per year.
Simple Interest = (Principal × Rate × Time) / 100
= $700 x 0.06 x 3
= 126 / 100
= 1.26

the average distance of the moon from earth is 386,242,560 m. Represent 386,242,560 in scientific notation
Answer:
3.86242560*10^8
Step-by-step explanation:
Scientific notation is in the form a*10^b
where b is an integer. And 1 <= a < 10
The average distance of the moon from earth represent as; 3.86242560 x 10^8 scientific notation.
How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have[tex]1 \leq a < 10[/tex]
where b is an integer which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. For an instant, we can ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
We have been given that the average distance of the moon from earth is 386,242,560 m.
We know that the scientific notation is in the form [tex]a \times 10^b[/tex]
It can be written as;
38624256 × 10
Or
3.86242560 x 10^8
