Well if u think about it 8*5= 40ft ²
Answer:
C) 25%
Step-by-step explanation:
let salt be 's'
let water be 'w'
0.25 = 25%
When the number of data points is odd the formula to find the Ranking of the Median is (n+1)/2, When the number of data points is even the ranking of the Median will be the AVERAGE of n/2 + n/2 +1, where n is the number of data points.
In our case the ranking of the Median is the average (20+21)/2 = 20.5.
1- How many points are below the Median =20
Lower half = 20, Upper half = 20 & Median = 20.5 (Don't forget Median is the ranking of data points).
Again the 1st Quartile is at 10.5, so 10 data points are below the 1st Quartile
and 20 points are between Q1 & Q3
Answer for a)
Since the coordinates are arranged as (x, y, z), then 3 would be for x, 0 would be for y, and 1 would be for z. The x is the length, the y is the height, and the z is the width. It is said that the x-axis value is 3 so there are 4 letters on the 3 value which are: P, S, B, and A. Now, let's look at the 0 on the y-axis. Since the y-axis is the height, then there are 2 letters remaining: A and B. Now, the z-axis is 1. So the letter for point (3, 0, 1) is... B.
Answer for b)
For the x-axis, P is at 3. For the y-axis, P is at 2. For the z-axis, P is at 1. So the coordinate of P is: (3, 2, 1).
Finding y intercept and x intercept is easy:
X intercept will be of the form (x,0) and y intercept will be of the form (0,y)
● If you put x=0 in the equation, you will get y-intercept.
● If you put y=0 in the equation, you will get x-intercept.
______________________________
Given equation: 2x - 4y = 10
◆ Put x = 0
2×0 - 4y = 10
=> -4y = 10
=> y = 10/(-4)
=> y = -5/2
Thus y intercept is (0, -5/2)
◆Put y = 0
2x - 4×0 = 10
=> 2x = 10
=> x = 10/2
=> x = 5
Thus the x intercept is (5,0)
