A fitted multiple regression equation is Y = 28 + 5X1 - 4X2 + 7X3 + 2X4. When X1 increases 2 units and X2 increases 2 units as w
ad-work [718]

Answer:

A. Increase by 2

Step-by-step explanation:

Given that a  fitted multiple regression equation is

Y = 28 + 5X_1 -4X_2 + 7X_3 + 2X_4

This is a multiple regression line with dependent variable y and independent variables x1, x2, x3 and x4

The coefficients of independent variables represent the slope.

In other words the coefficients represent the rate of change of y when xi is changed by 1 unit.

Given that x3 and x4 remain unchanged and x1 increases by 2 and x2 by 2 units

Since slope of x1 is 5, we find for one unit change in x1 we can have 5 units change in y

i.e. for 2 units change in x1, we expect 10 units change in Y

Similarly for 2 units change in x2, we expect -2(4) units change in Y

Put together we have

10-8 =2 change in y

Since positive 2, there is an increase by 2

A. Increase by 2

Find the probability of this event. Enter the answer as a fraction in simplest form, as a decimal to the nearest hundredth, and
Lapatulllka [165]

Answer:

2/3, or 0.66, 66%

Step-by-step explanation:

The spinner lands on Blue or Green. That's two thirds of the spinner.

The fraction is simple enough. The decimal is also simple enough.

To get a percent from a decimal, you need to multiply whatever decimal it is by 100.

Hope this helped.

elena-14-01-66 [18.8K]

Step-by-step explanation:

The formula is given by :

s=\dfrac{m}{360}\times 2\pi r

We have,

m = 19° and d = 9 cm

So,

s=\dfrac{19}{360}\times 2\pi \times \dfrac{9}{2}\\\\s=1.49

Hence, this is the required soltion.
