The internal angle sum of a quadrilateral is :

C. 360°

The sum of internal angles of a polygon is determined by a formula :

\longmapsto (n - 2) × 180°

where n represents number of sides.

In a quadrilateral there are four sides,

So, plugging 4 in the formula :

  • (4 - 2) \times 180°

  • 2 \times 180°

  • 360°

Seventy homes that were for sale in Tampa, Florida in Spring of 2019 were randomly selected. A regression model to predict house
Art [367]

Answer:

d. The slope of the relationship between firstfloorsquarefootage and price is moresteep for homes near the beach than elsewhere in Tampa.

Step-by-step explanation:

In this regression model, we have a positive slope. This positive slope is indicative of an increase. So to interpret this slope, we would say that the slope of the relationship that exists between the two variables (price and firstfloorsquarefootage) is steeper for the homes that are closer to the beach compared to the ones that are elsewhere. Therefore option D is our answer.

20% of what number is 30? Pick the proportion that could be used to solve.
Colt1911 [192]

30 is 20% of 150

Working out percentage problems of the form "30 is 20 percent of what number?"

We have, 20% × x = 30

or,  

20/100 × x = 30

Multiplying both sides by 100 and dividing both sides by 20,

we have x = 30 ×  100/20

x = 150

If you are using a calculator, simply enter 30×100÷20, which will give you the answer.
