A parallelogram has a height of x cm. The length of its base is 4 cm greater than its height. A triangle has the same height as

LuckyWell [14K]

The value of x when the triangle and the parallelogram have the same area is 6 units

<h3>The dimensions</h3>

The dimension of the parallelogram is given as:

Height = x
Base = 4 + x

The dimension of the triangle is given as:

Height = x
Base = 20

<h3>Areas</h3>

The area of a shape is the amount of space it occupies

The area of the parallelogram is calculated as:

$Area = x (4 + x)$

The area of the triangle is calculated as:

$Area = 0.5 \times 20 \times x$

$Area = 10x$

Both areas are equal.

So, we have:

$x(4 + x) = 10x$

Divide both sides by x

$4 + x = 10$

Subtract 4 from both sides

$x =6$

Hence, the value of x is 6 units

To test if x is a good predictor of y in Simple Linear Regression we need to determine whether:

I am Lyosha [343]

Option A is correct.

For testing, if x is a significant predictor of y in simple linear regression, we need to determine if the slope is significantly different from zero.

What is linear regression?

A statistical technique known as linear regression is used to represent the connection between a scalar answer and one or more explanatory factors. When there is just one explanatory variable, simple linear regression is employed; when there are numerous explanatory variables, multiple linear regression is utilized.

Based on the value of another variable, linear regression analysis makes predictions about the value of the first variable. The dependent variable is the one you're trying to forecast. The independent variable is the one you are utilizing to make a prediction about the value of the other variable.

The points shown represent a relation.

Liula [17]

Answer:

B. The relation is a function because each x-value corresponds to only one y-value.

Step-by-step explanation:

In order for a relation to be a function, each x-value must have only one y-value. Decimals and negative numbers are negligible.

PLEASE HELP ME ANY ANSWERS I WILL ACCEPT IT PLEASEEEE!!!!!) Marina wants to purchase a rosebush for d dollars at a garden store.

victus00 [196]

PART A

write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. d-(d-5).10 = 27.5 (if you put d in as 30!)

PART B

write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. d-(d*.10)-5 =22 (if you put d in as 30!)

PART C

which order will save marina more money? explain your reasoning.

d-(d*.10)-5 This equals less! if you put in 30 as an example

So, A) d-(d-5).10 B) d-(d*.10)-5 C) d-(d*.10)-5
