Answer:
x = -5
Step-by-step explanation:
x+7=2
-7 | -7 -7 from both sides
x= -5
<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.)
Answer:
we conclude:
Step-by-step explanation:
Given
To determine
In order to determine f(g(7)), the first step we need to do is to determine g(7)
so substitute x = 7 in g(x) = 2x + 2
so now we have
The next step to do is to substitute x = 16 in f(x) = 4x + 21
so we have
Therefore, we conclude:
In this case we can make a proportion.
Now cross multiply.
9600 = 75x
Divide both sides by 75.
X=128
