=======================================================
Explanation:
With the outlier, the mean is
m = (10+12+17+18+22+30+101)/7 = 30
I added up the values and divided by 7 since there are 7 values being added up.
Without the outlier 101, the mean is now
n = (10+12+17+18+22+30)/6 = 18.1667 approximately
We're dividing by one less item this time.
Subtract the values of m and n
m-n = 30-18.1667 = 11.8333
This rounds to 11.83
The large outlier 101 increases the mean by roughly 11.83
Any time the outlier is larger than the main cluster of values, the mean is pulled to be larger than it should be if we ignored the outlier. The further the outlier, the stronger the pull and the more skewed the mean will get.
Note how the median of {10,12,17,18,22,30} is 17.5 which is a better measure of center compared to m = 30 found earlier.

Step-by-step explanation:
i believe the way your learning is that you have to add or subtract both numbers and then add the letter next to the answer. number 3 is just x because -1- 4x = 0 and just add the x.
Sarita showed the steps to solving the equation.
5 (x minus 3) + 7 (x + 4) = 73
Steps
Sarita’s Solution
Sarita’s Verification
1
5 x minus 15 + 7 x + 28 = 73
5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73.
2
(5 + 7) x + (negative 15 + 28) = 73
3
12 x + 13 = 73
4
12 x + 60
5
x = 5

A one-year membership to a gym costs $725. The registration fee is $125, and the remaining amount is paid monthly. Define a variable. Then write and solve an equation to find how much new members pay each month NEEDS WORK please help i'm in the middle of a quiz nd i'm so gonna fail
Given :
A one-year membership to a gym costs $725.
The registration fee is $125.
To Find :
How much new members pay each month.
Solution :
Remaining fee = Total fee - Registration fee
R = $( 725 - 125 )
R = $600
Amount of fee paid monthly is :
[tex]C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50[/tex]
Therefore, monthly fee is $50.
Hence, this is the required solution.

The gravity on the surface of the moon is 0.17 of the surface gravity on Earth. If Jack weighs 156 pounds on Earth, what would be his weight on the moon? (Will give brainliest)
Answer:
Jack will weigh 26.52 pounds
Step-by-step explanation:
x = 156 (Your weight on Earth)
y = 0.17 (Surface Gravity)
z = Your weight on the moon
x * y = z
156 * 0.17 = 26.52
Jack will weigh 26.52 pounds.
If Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
It is given that,
Gravity on the surface of the moon = 0.17
Weighs of Jack on Earth = 156 pounds
Mass of Jack,
W=mg
156 pounds = m × 9.81 [ g on earth = 9.81 m/s²]
m = 15.902 kg
The weight of Jack on the moon is,
W= 15.902 kg × 0.17
W=2.565 N
Thus, if Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.

what is the slope of the line?
Answer:
1/2
Step-by-step explanation:
Hope this helps:)
Answer:
1/2 simplified
Step-by-step explanation:
You do rise over run. That means you count up from the (-2, -1) point then get level with the other point (2, 1) And that should give a right triangle. Then count how many boxes are going up put that number on top. Then count how many boxes are going across and that number goes on bottom. You then get 2/4, but I simplified it to 1/2.
Also you can do...
[tex]\frac{y2 - y1}{x2 - x1}[/tex] plug in
[tex]\frac{1 + 1}{2 + 2}[/tex] = [tex]\frac{2}{4}[/tex]
The reason I added because it was 1 - - 1 or one minus negative 1 so two negatives make a positive same thing with the bottom it was 2 - - 2.

What is the distance between the points A(-5, 3) and B(4, -1)? *
Answer:
[tex]\sqrt{97}[/tex] units
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(- 5, 3) and (x₂, y₂ ) = B(4, - 1)
d= [tex]\sqrt{(4+5)^2+(-1-3)^2}[/tex]
= [tex]\sqrt{9^2+(-4)^2}[/tex]
= [tex]\sqrt{81+16}[/tex]
= [tex]\sqrt{97}[/tex] ≈ 9.85 ( to 2 dec. places )

Lets look at this in a more simple way:
[tex](5.9[/tex] × [tex]10^{6} )[/tex] × [tex](3.2[/tex] × [tex]10^{4} )[/tex]
First, let's move [tex]10^{6}[/tex] and switch it's places with 3.2:
(5.9 × 3.2) × ([tex]10^{6}[/tex] × [tex]10^{4}[/tex])
Then, let's simplify:
18.88 × [tex]10^{10}[/tex]

Amber worked 2.2 hours on Monday and 5.9 hours on Tuesday. Her pay rate is $9.50 per hour. How much will Amber be paid for two days?
Answer:
$76.95
Step-by-step explanation:
Amber worked for 2.2 hours on Monday and she makes $9.50 per hour, so that means you multiply 9.50 x 2.2 and it equals 20.9, then it says she works 5.9 hours on Tuesday, so that means you multiply 9.50 x 5.9 and it equals 56.05, so in total you add 20.9 from Monday and 56.05 from Tuesday and it equals 76.95, which means $76.95 is how much Amber will be paid.
