Answer:

x^3 + x^2 + 4x - 20.

Step-by-step explanation:

I have assumed there is a + between the 3x and the 10.

f(x) * g(x)

= (x^2 + 3x + 10)(x - 2)

=  x^3 + 3x^2 + 10x - 2x^2 - 6x - 20

= x^3 + x^2 + 4x - 20.

When the outliers are removed, how does the mean change? (2 points) dot plot with 1 on 50, 1 on 76, 1 on 78, 2 on 79, 1 on 80, 1
777dan777 [17]

Answer:

Answer: The mean increases by 3

Step-by-step explanation:

The original data set is 

{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}

The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.

The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77

If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80

So in summary so far

old mean = M = 77

new mean = N = 80

The difference in values is N-M = 80-77 = 3

So that's why the mean increases by 3

Jasmine can run 4 5/6 miles in 2/3 of an hour. how many miles can she run in one hour
Jlenok [28]

Jasmine can run in one hour is 7.25 miles.

<h3>What is the formula of unitary method?</h3>

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Jasmine can run 4\frac{5}{6} miles in \frac{2}{3} of an hour.

\frac{2}{3} of an hour = 4\frac{5}{6} miles

                     = \frac{29}{6} miles

By using unitary method we will find the value of an hour.

1 hour = \frac{\frac{29}{6} }{\frac{2}{3} }

          =  \frac{29}{6} × \frac{3}{2}

          = \frac{29}{4}

1 hour  = 7.25 miles

Hence, Jasmine can run in one hour is 7.25 miles.
