Answer:
y = 2x/3 + 2/3
Step-by-step explanation:
1. Find the slope of the given line.
y = mx + b
6x + 7y = 3y -3
4y = -6x - 3
y = (-6x-3)/4 = -3x/2 - 3/4
The slope of y = -3/2
The slope of a line perpendicular to the line of 6x + 7y = 3y -3 would be the negative reciprocal of the slope so the slope of the line perpendicular would be -1/(-3/2) = 2/3
The equation would be:
y = 2x/3 + b
Since b is unknown, but a point is known, we plug in x and y values.
-8 = 2*(-13)/3 + b
Then solve for b:
b = 2/3
from the picture in every cup there are 1/5 of lemon + 4/5 of water.
the cups are 20
so 1/5 * 20 = 4
4 cup of lemon
Answer: statistic.
Step-by-step explanation:
A parameter is a measure of characteristic in a population.
A statistic is a measure of characteristic in a sample.
Given: A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.
Since group of 32 games out of 50 is representing a sample here.
So, 20.5% is the measure of sample, i.e. it is a statistic.
Median means middle, the center line is at 3 indicating median. With box-and-whiskers plots minimum [0] and maximum [6] are marked by the farthest apart values. The other lines are quartile marks. [2.25 & 4.75]
A: 3
B: Q1=2.25, Q2=4.75
C: min=0, max=6
