Answer:

first: Definitions

mean: the average or the most common value in a collection of numbers

(So u add all numbers and then divide the answer by how much numbers there were)

median: Is middle value.

(example: 4, 5, 6) (The median will be the middle which is 5) (But if there are even amount of numbers like this: 4, 5, 6, 7) (Then you will get the two middle numbers which in this case are 5 and 6 you add them and then divide by 2.)

standard deviation: measures the spread of the data about the mean value

Step-by-step explanation:

Now lets get to problem!

we have numbers:

24, 20, 16, 18, 18, 26, 22

the mean will be: 144 (remember now you have to divide by 7 because there are 7 numbers.)

So it would be 20.57

Now the median:

(Since there are 7 numbers you just find the number in the middle and that would be ur median.)

24, 20, 16, 18, 18, 26, 22

median answer: 18

Like we said: The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

So the standard deviation will be: 3.6

I hope this helps :)

What is the value of 2(3x − 6) − 5y if x = −2 and y = 6?

adoni [48]

Answer: 6 Hope this helps, please consider making me Brainliest.

Step-by-step explanation:

Let's plug in the assigned values of x and y:

2(3x - 6) - 5y --> 2(3(-2) - 6) - 5(6) =

2(-6 - 6) - 5(-6) =

2(-12) - (-30) =

-24 + 30 =

6

Answer:

The container can hold 18 gallons

Step-by-step explanation:

Assume the container can hold x gallons

∵ The container is $\frac{2}{3}$ full with water

∵ It can hold x gallons

→ Multiply $\frac{2}{3}$ by x to find the number of gallons in the container

∴ The number of gallons in the container = $\frac{2}{3}$ x

∵ 4 gallons of water pouring out

∵ It is $\frac{4}{9}$ full

→ Multiply $\frac{4}{9}$ by x to find the number of gallons left in it

∴ The number of gallons left in the container = $\frac{4}{9}$ x

→ The difference between the numbers of gallons is 4 gallons

∵ $\frac{2}{3}$ x - $\frac{4}{9}$ x = 4

→ Subtract the terms of the left side

∴ $\frac{2}{9}$ x = 4

→ Multiply both sides by 9

∴ 2x = 36

→ Divide both sides by 18

∴ x = 18

∵ x represents the full of the container

∴ The container can hold 18 gallons

a. What conjecture is being made?

The Conjecture being made is that is it is possible to measure the larger angle of the second fence based on the smaller angle.

b. What key details are given?

That the lines are parallel and the smaller angle is 35 degrees.

c. What is your plan of action?

My plan is to multiply 35 and 2 then subtract 35 times 2 with 360 and the answer is 290 and divide 290 by 2 to get 145 degrees as the larger angle.
