choose two additional data values for the given data set so that the given data set is true A. the median is 8 4,12,14,10_,_ B. The median is 11 4,12,14,10,_,_ C. The mean is 10 4,12,14,10,_,_

Answers

first step in finding the median is ordering the numbers 1. 4,10,12,14. Then you find out the number in the middle.
step 1: 4,10,12,14
step 2: now, take out the first number so 10,12,14
Step 3: now take out the last number so 10,12
step 4: since there are two middle numbers, you average them. If you didn't know already, all you have to do to average them is add the two numbers together then divide them by two so 10+12=22 /2=11
now you want to find two numbers that if averaged with 11, make 8. so you could do two . final answer is 4,5,5,10,12,14

1. 4,12,14,10,5,5
2. 4,12,14,10,12,10

now mean is just average so what you would do is just add all your numbers up and divide by the amount of numbers you added.

Maria has five more than twice as many hats as Beth. Together they have 26 hats. How many hats does Maria have?

Answers

Maria has 19 hats.

Calculation of number of hats:

Here we assume

b=beth

m=maria

Now the equation should be

2b+5=m

b+m=26

here we put m equation

So,

b + 2b + 5 = 26

3b = 21

b = 7

So, the hats should be = 26 - 7 = 19

Maria has 19 hats.

b=beth
m=maria
Equations: 2b+5=m
b+m=26

plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats

How do you solve 9-2x=35

Answers

The required solution to the equation 9 - 2x = 35 is x = -13.

To solve the equation 9 - 2x = 35, we can follow these steps:

Start with the given equation: 9 - 2x = 35.

We want to isolate the variable x on one side of the equation, so let's begin by getting rid of the constantterm on the left side by subtracting 9 from both sides:

9 - 2x - 9 = 35 - 9

Simplifying, we have:

-2x = 26

Next, we want to solve for x, so we need to isolate x. Divide both sides of the equation by -2:

-2x / -2 = 26 / -2

This simplifies to:

x = -13

Therefore, the solution to the equation 9 - 2x = 35 is x = -13.

You are trying to solve x. So first, you have to find out what the opposite of adding 9 is. If you said, subtracting 9, you got it. So subtract 9 on both sides. So on the left side, it's now 0. 39 - 9 on the right side equals 26. So now, it should look like this: -2x=26. Now find the opposite of multiplying -2. It would be dividing -2. So divide -2 on both sides. So now, you have x on the left and -13 on the right. So that means, x = -13.
Hope this helps. :-)

The square abcd has side length 10cm. E is the midpoint of BC. Work out the length of DE. Answer to 1 decimal place.

Answers

-- DEC is a right triangle.

-- DC is one side of the square = 10 cm
-- EC is half the side of the square = 5 cm
-- DE is the hypotenuse = square root of (5² + 10²) = √(125 cm²) .

-- Truncated to one decimal place, that's 11.1 cm.

-- Rounded to one decimal place, it's 11.2 cm.

Think of it as a triangle. E is the midpoint of BC, so EC is 5cm. Then CD is 10cm. Pythagoras it, so 5^2 + 10^2 = DE^2. Rt(125) = 11.2 to 1 decimal place. That's the answer
