Hey!

-------------------------------------------------

The range in a data is the value of subtracting the highest value to the lowest value.

-------------------------------------------------

First, we need to the the values in order from least to greatest.

26, 27, 27, 30, 32, 33, 33, 34, 40, 45

Second, we subtract the greatest value to least value.

45 - 26 = 19

-------------------------------------------------

Hence, the range is 19!

Hope This Helped! Good Luck!

If √6x

weeeeeb [17]

Answer:

B) 15

Step-by-step explanation:

sqrt(6x) = 3 sqrt(10)

Square each side

(sqrt(6x))^2 = (3 sqrt(10))^2

Remember (ab)^2 = a^2 b^2

6x = (3^2) sqrt(10))^2

6x = 9 * 10

6x = 90

Divide each side by 6

6x/6 = 90/6

x = 15

Is 9-8x=y proportional

andrew-mc [135]

Answer:

No, proportional relations are of the form,

$y = mx$

Step-by-step explanation:

The given equation is

$9 - 8x = y$

This is an equation in the form:

$y = mx + c$

since we can rewrite to get:

$y = - 8x + 9$

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

$y = mx$

From the diagram below, if AD = 5, and DB = 10, what is the length of CD?

bazaltina [42]

Answer:

Step-by-step explanation:

According to Euclidian theorem:

h^2 = AD*CD (h is the height, DB in this case)

rewrite the equation by using given values

10^2 = 5*CD find the square value of 10

100 = 5*CD divide both sides by 5

20 = CD
