A null hypothesis is a kind of hypothesis used in statistics. It proposes that, in a set of given observations, no statistical significance exists. The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
So, for this problem, given that three new colors have been proposed for the jeep grand cherokee vehicle. those are silvered-blue, almond, and willow green, the null hypothesis is:
H0: b. that there is no preference between the colors.
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.
Answer:
Step-by-step explanation:
Y= -3x + 4..........(1)
Y= 4x - 10...........(2)
Substituting (1) into (2)
-3x + 4 = 4x - 10
-3x - 4x = -10 - 4
-7x = -14
x = -14/-7
x = 2
Putting x in (2)
y = 4(2) - 10
y = 8 - 10
y = -2
You have the correct answer being (-5,3). Simply add the parentheses around the point
