Answer:
A. y-6=7(x+2)
Step-by-step explanation:
When we use the coordinate point given and plug into our equation choices, A is the only choice that returns a correct result.
y-6=7(x+2)
First we use the x coordinate
y-6=7[(-2)+2]
y=6
Next we use the y coordinate
y-6=7(x+2)
6-6=7(x+2)
-14=7x
x=-2
Answer:
It would only take three hours.
Step-by-step explanation:
1/6+1/x=1/2
x + 6=3x
6=2x
x=3hr
Answer:
see explanation
Step-by-step explanation:
Supplementary angles sum to 180° , then
x + y = 180 , that is
y + y = 180 ( multiply through by 3 to clear the fraction )
y + 3y = 540
4y = 540 ( divide both sides by 4 )
y = 135°
Answer:
i. 18 miles per hour is an outlier
ii. the outlier decreases the mean speed
Step-by-step explanation:
An outlier in a given data is one of the values that is far greater or lesser compared to others. It affect the mean and standard deviation of a given data significantly.
From the given data, 18 is far too small compared to other values. This is certainly an outlier. This would affect the mean speed by decreasing the value.
An interquartile range is a measure of differences among data by dividing a set of given data into quartile. Increasing the value of the outlier would increase the interquartile range.
