Pls Mark me branliest....
The equation showing the equal result as 1/4 ÷ 2 = 1/8 is 1/4 = 2 × 1/8
What is an equation?An equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.
For example, 2x - 5 = 13.
Given that, an equation 1/4 ÷ 2 = 1/8, we need to find an equation giving the same result as it,
1/4 ÷ 2 = 1/8
Solving,
1/4 ÷ 2 = 1/8
1/4 = 2 × 1/8
Hence, the equation showing the equal result as 1/4 ÷ 2 = 1/8 is 1/4 = 2 × 1/8

Shawn would like to know the average height of the trees in the back field at school. She measures the heights of each tree in a random sample of 20 trees. The mean height of Shawn's sample is 61 inches, and the MAD (mean absolute deviation) is 2 inches.
Select all that apply
Question options :
The median height of the sample must be between 59 and 63 inches.
Another random sample of 20 trees is likely to have a mean between 57 and 65 inches.
The mean height of these 20 trees is likely to be the same as the mean height of all trees in the back field .
The mean height of these 20 trees is likely to be the same as the mean height of a second random sample of 20 trees.
Shawn would be more likely to get an accurate estimate of the mean height of the population by sampling 40 trees instead of sampling 20 trees.
Answer:
The median height of the sample must be between 59 and 63 inches.
The mean height of these 20 trees is likely to be the same as the mean height of all trees in the back field .
The mean height of these 20 trees is likely to be the same as the mean height of a second random sample of 20 trees.
Shawn would be more likely to get an accurate estimate of the mean height of the population by sampling 40 trees instead of sampling 20 trees
Explanation:
The mean absolute deviation is the summary of absolute deviations from the central point or average of a data set. The central point measurement can be the mean, median or mode of the data set. An average absolute deviation can be used instead of a standard deviation to measure dispersion from central point.
In the above case, a sample is taken of 20 trees and there is a mean absolute deviation of 2, hence, median can be between 59 and 63. Also sample represents population, therefore mean of another sample taken is likely to be same as the previous one taken. Mean invariably gets more accurate as sample size increases too.

In the diagram. PQ is parallel to BC.
APB and AQC are straight lines.
PQ = 8 cm, BC = 10 cm and AB = 9 cm.
Calculate PB
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]
Plug in the values
[tex] \frac{9}{AP} = \frac{10}{8} [/tex]
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8

A jewelry store is having a going out of busniess sale. All merchandise is marked 40% off the reguler price. The regualr price of a watch is $59.95. Find the amount of the discount and the sale price.
Answer:
Amount of the Discount: $23.98
Sale Price: $35.97
Step-by-step explanation:
In order to calculate the discount we first need to turn this percentage into a decimal by dividing it by 100. Once we have it in decimal form we subtract that value from 1. Finally, we multiply this new decimal by the original price in order to obtain the sale price like so...
40 / 100 = 0.40
1 - 0.40 = 0.60
0.60 * 59.95 = 35.97
Now we have the sale price which is $35.97 now we can subtract this value from the original price to calculate the amount of the discount.
59.95 - 35.97 = 23.98

Answer:
1/6 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours.
(1/8 mi)/(3/4 h) = (1/8×4/3) mi/h = 1/6 mi/h
The snail's speed is 1/6 miles per hour.

The determinant of the matrix will be calculated as below:-
D = ( 6 x 6 ) - ( -9 x -4 )
D = ( 36 - 36 )
D = 0
Here the determinant of the matrix is zero. Therefore, the matrix is not invertible.

AB and BC form a right angle at point B. If A= (-3,-1) and B = (4,4), what is the equation of BC?
A. x+3y= 16
B. 2x+y= 12
C. -7x - 5y=-48
D. 7x-5y= 48
Answer: We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48
Answer:
the equation of BC is:
(C) -7x - 5y = -48

The equation modeling the population growth of a small town is P(t)=30000(1.02)^t, where P represents the population, and t represents the years from now. What is the approximate population change that occurs between 2 years from now and 10 years from now.
a.5,358
b.6,570
c.31,212
d.35,150
e.36,570
Answer: I’m not for sure but I got 31,212
Step-by-step explanation: You multiply 30000 to 1.02 and then with the 2 and the 10 you divided and get 31,212
The population change between these years is (a) 5358
The population model is given as:
[tex]\mathbf{P(t) = 30000(1.02)^t}[/tex]
When t = 2, we have:
[tex]\mathbf{P(2) = 30000(1.02)^2}[/tex]
[tex]\mathbf{P(2) = 31212}[/tex]
When t = 10, we have:
[tex]\mathbf{P(10) = 30000(1.02)^{10}}[/tex]
[tex]\mathbf{P(10) = 36570}[/tex]
The population change is then calculated as:
[tex]\mathbf{\Delta P = P(10) - P(2)}[/tex]
So, we have:
[tex]\mathbf{\Delta P = 36570 - 31212}[/tex]
[tex]\mathbf{\Delta P = 5358}[/tex]
Hence, the population change between these years is (a) 5358
