<u>Answer:</u>
1 and 5 are correct.
<u>Step-by-step explanation:</u>
1. The mean is affected by outliers. - TRUE
(the mean is the average so each of its values affect it.)
2. The mean is always a more accurate measure of center than the median. - FALSE
(the mean gives a better idea of the values while the the central values for normal distributions are described using the median value.)
3. Removing an outlier from a data set will cause the standard deviation to increase. - FALSE
(it makes the data set more normal by reducing the standard deviation, not increasing it. )
4. If the data set’s distribution is skewed, then 95%of its values will fall between two standard deviations of the mean. - FALSE
(the 68-95-99.9 rule works for the normal distribution, but the skewed distribution.)
5. If a data set’s distribution to skewed to the right, its mean will be larger than its median. - TRUE
(the mean is always pulled towards the direction of the skewness.)
I believe the answer is 2C-11
Answer:
The cost of the bench is <u>425 dollars</u>.
Step-by-step explanation:
<u>Let x represent the garden table.</u>
<u>Let y represent the bench.</u>
x + y = 804
x = y - 46
<u>Use the substitution method.</u>
y - 46 + y = 804
2y - 46 = 804
<u>Add 46 to both sides.</u>
2y = 850
<u>Divide both sides by 2.</u>
y = 425
Answer:
The cost of the bench is 425 dollars.
Answer:
Step-by-step explanation:
i believe it the answer should be x=3 and y=2
Well, first what is 6-3=3 so now whats 3-2? 3-2=1
6-3=3-2
