Answer:
c) skewed to the right.
Step-by-step explanation:
We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:
And if is skewed to the left then we have:
If the distribution is symmetric we need to satisfy:
For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.
So for this special case we can say that the 
. And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:
c) skewed to the right.
Answer:
52.40

Discussion
Suppose the meal starts out as x.
She pays 5% of x as a sales tax
So that brings the total up to 100% + 5% = 105%
Before paying, she pays 20% on x as her tip. The tax does not touch the tip.
So that brings the total up to 100% + 5% + 20% = 125% of this is based on x, the cost of the meal.
So 125% of x = 65.50 change the % to a fraction
125/100 * x = 65.50 Multiply both sides by 100/125
125/100 * 100/125x = 100/125 * 65.50
x = 100/125 * 65.50 Multiply by 100
x = 6550 / 125 Divide by 125
Check
Tax = 5% * 52.40 = 5/100 * 52.40 = 2.62
Tip = 20%*52.40 = 20/100 * 52.40=10.48
Meal = 52.40
Total 65.50 Just as it should
Answer:
Step-by-step explanation:
1. Given that the local ice cream shop is deciding whether or not to hire a new worker. The shop must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y=10x+30 where x=hours.
We find that this is of the form y = mx + B where
m = 10 and B = 30
Hence slope = m = 10
Answer is 10,
and it represents the rate of change of y for a unit change in x.
2. The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.
3. The answer is "Correlation, because time of day doesn't cause a person to run faster or slower ".
That's the correct answer because causation would mean there is a cause and effect and in the question, there is no cause. It can't be the last one because there is enough information. It also can't be the third one because there is a relationship since he shown he runs faster in the evening. Also I took the test and it was right!
Answer:
The fourth option is the correct answer
Step-by-step explanation:
The given expression is
-2n(5+n-8-3n)
Given that n=3,We substitute the value of n into the expression and simplify.
This implies that,
-2n(5+n-8-3n)=-2(3)[5+3-8-3(3)]
=-6(5+3-8-9)
=-6(-9)
=54
Hence the answer is 54
10% = 5
80% = 40
2% = 1
82% = 41
41
