What is the value of x?

You are reducing a map of dimensions 2 ft by 3 ft to fit to a piece of paper 8 in. by 10 in. What are the dimensions of the larg

Alchen [17]

Answer:

$6\frac{2}{3}$ in. by 10 in.

Step-by-step explanation:

2 ft by 3 ft, inches is:

2 * 12 = 24 inch

3 * 12 = 36 inch

24 * 36

Thus, to make 36 into 10, we divide 36 by 3.6 to get 10:

36/3.6 = 10

To keep ratio equal, we need to divide 24 by 3.6 to get:

24/3.6 = $6\frac{2}{3}$

Thus, Third answer choice is right.

2x(5+3x)-x find the coefficient of x

s344n2d4d5 [400]

To start, we need to distribute

multiply 2x by everything in the parenthesis

2x (5 + 3x) - x

2x × 5 = 10x

2x × 3x = 6x²

now we have...

10x + 6x² - x

simplify

6x² + 9x

the coefficient of x is 9!

Suppose a horticulturist measures the aboveground height growth rate of four different ornamental shrub species grown in a green

torisob [31]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The decision is to reject the null hypothesis at a significant level of significance $\alpha = 0.05$ There is sufficient evidence to conclude that at least one of the population mean is different from at least of the population

Step-by-step explanation:

From the question we are told that the claim is

The mean growth rates of all four species are equal.

The null hypothesis is

$H_o : \mu _1 = \mu_2 = \mu_3 = \mu_4$

Th alternative hypothesis is

$H_a: at \ least \ one \ of \ the \ means \ is \not\ equal$

From question the p-value is $p-value = 0.015$

And since the $p-value < \alpha$ so the null hypothesis will be rejected

So

The decision is to reject the null hypothesis at a significant level of significance $\alpha = 0.05$ There is sufficient evidence to conclude that at least one of the population mean is different from at least of the population

Solve for a 1/4 (20 - 4a) = 6- a G. No Solution H. All Real Numbers I. -6 J. -6

Margaret [11]

Answer:

THE EQUATION HAS NO SOLUTION!

Step-by-step explanation:

Simplify 1/4 , (1/4 • (20 - 4a)) - (6 - a) = 0 , 3.1 Pull out like factors : 20 - 4a = -4 • (a - 5) , (5 - a) - (6 - a) = 0 , -1 = 0 , 5.1 Solve : -1 = 0, THERES NO SOLUTION MATE TRUST ME!
