Answer:
Check the explanation
Step-by-step explanation:
The average amount of the exercise hours at the same time as I am at my home town is 50 hours a month
Does this diverge from average exercise while I am not in my home town? This is 46 hours
So,
Null: H0: μ = 30
H1: μ ≠ 30
Two tail test
Formula:
z = (46 - 50)/SD
Answer: Option c.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the equation:

Solve for "y" in order to write in Slope-Intercept form:

Now you can identify that that the slope and the y-intercept are:

A posive slope means that the the line moves upward from left to right.
With this information, you can conclude that the the graph that best represents the given equation is the graph shown in the Option c.
f(x) = (3x+5)/7
Step 1:
we write f(x) as y
y=(3x+5)/7
Step 2:
switch y by x and x by y
x=(3y+5)/7
Step 3:
solve for y,
x=(3y+5)/7
multiply both sides by 7
7x=3y+5
subtract 5 from left side
3y=7x-5
divide both sides by 3
y= (7x-5)/3
f⁻¹ (x) =(7x-5)/3
Answer:
-17
Step-by-step explanation:
3 + 4(-5)
= 3-20
= -17
Hope this helps!
Answer:
The answer is x=10
Step-by-step explanation:
5/6x - 10 = 1/3x -5 multiple both sides by 6
5x - 60 = 2x -30 move the terms
5x - 2x = -30 +60
3x = 30 divide by 3
x = 10
