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:
5y(2y-3)^2
Step-by-step explanation:
Part A:
Yes this is a function of x. Specifically the function is f(x) = x^2
The inputs (x) are squared to get the outputs (y).
For example,
f(x) = x^2
f(-3) = (-3)^2 <<--- input is x = -3
f(-3) = 9 <<--- output is 9
The pair of values -3 and 9 are shown in the table (column on the very right side)
The fact that each input leads to exactly one output is what makes this a function. If we had an input lead to multiple outputs, then it wouldn't be a function.
=============================================================
Part B
Replace every x with 150 and then use the order of operations PEMDAS to simplify
f(x) = 20+3x
f(x) = 20+3*x
f(150) = 20+3*150 <<--- x has been replaced with 150
f(150) = 20+300
f(150) = 320
So the value of f(150) is 320
The input is 20
The output is 320
x is the number of hours
y or f(x) is the total cost
So this means f(150) = 320 represents the idea that 150 hours of renting the rowboat leads to a total cost of $320
(x•19)4=752
x would be multiplied by 19 then after it’s getting multiplied by 4.
