Step-by-step explanation:

Sum of interior angles =(n-2)180

Number of sides = 7 - 2 =5

So 5 multiply 180

Answer:

The other two angles are 75° and 125°.

Step-by-step explanation:

Let three angles are 2x, 3x and 5x.

The smallest angle is 50.

It means,

2x = 50

x = 25

So,

3x = 3(25) = 75°

5x = 5(25) = 125°

So, the other two angles are 75° and 125°.

Step-by-step explanation:

since

25⁰= 1 minute

x⁰ = 11 minutes

cross multiply

25 x 11= x

x= 275⁰

temperature after being turned on=275⁰

temperature after 11 minutes= 275⁰ + 75⁰= 350⁰

temperature(x) after being turned on

25tt=x

temperature (x) after minutes

x= 25tt + 75⁰

A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?

Damm [24]

Answer:

Step-by-step explanation:

Find the predicted y value when x=1:

$\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5$

Find the residual:

$\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6$

Because our residual is positive, this is an indicator that our predicted y value is too low.
