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.

Step-by-step explanation:
4 is greater than 3
sqrt15 is greater than sqrt6
So 4+sqrt15 must be greater than 3+sqrt6

Answer:
(x, y) → (-∞, -∞), (+∞, +∞)
Step-by-step explanation:
The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:
x → -∞, f(x) → -∞
x → ∞, f(x) → ∞
Answer:
290
Step-by-step explanation:
First, add two digit number from them.
50 + 30 = 80
Second, add the last two numbers.
6 + 4 = 10
So, add these two results.
80 + 10 = 90
Final, all of theses results are added to three digit number of second number.
So, final result is
200 + 90 = 290
