Step-by-step explanation:
A negatively skewed distribution means that the distribution curve doesn't fall evenly on both sides of the median, but stretches out further to the low end. If the values above the median are only slightly above the median, but those below it could be far below it, the average (mean) will be below the median. If the mean (average) is 68, then the median must be above it, or 72.
Answer:
x = 2 and y = 1
Step-by-step explanation:
First, solve for y by substituting the second equation as x into the first equation
-2x - 3y = -7
-2(y + 1) - 3y = -7
Simplify and solve for y
-2y - 2 - 3y = -7
-5y - 2 = -7
-5y = -5
y = 1
Solve for x by plugging in 1 into the second equation
y + 1 = x
1 + 1 = x
2 = x
So, the answer is x = 2 and y = 1
B)
it is 15 more than A so the A has to go first

Answer:
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span>x−3</span>2</span></span>
Explanation:
Follow the steps:
<span><span>f<span>(x)</span></span>=2x+3</span>
1- replace <span><span>f<span>(x)</span></span> with y →y=2x+3</span>
2- simply switch <span>x and</span> so the equation looks like <span>x=2y+3</span>
3- use algebra to solve<span> for y</span>. (isolate y)
<span>x=2y+3</span>
<span>x−3=2y</span>
<span><span><span>x−3</span>2</span>=y</span>
This is the inverse function and is written as
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span><span>x−3</span>2</span></span></span>
