WILL GIVE BRAINLIEST!!! Write each of the following expressions without using absolute value.


|z-7|-|z-9| if Z is less than 7

Answers

Answer 1

Answer:

If z<7, then z-7 is negative, and |z-7| is positive.  So, with the understanding that z-7 is positive, the first part of this expression becomes:

7-z for z<7

Similarly:  if z<7, then z-9 is negative and |z-9| is positive.  Thus, -|z-9| is equivalent to (9-z).

|z−7|−|z−9|, if z<7 becomes (7-z) - (9-z) for z<7.  Simplifying this, we get:

7 - z - 9 + z = -2

Answer 2

Answer:

7 - z - 9 + z = -2

What do you think of when you hear the word statistics?

Answers

Answer:

Whenever I hear Statistics I think of numbers and the different probabilities

and I also sometimes think of numbers but overall, it depends on the sense of how it is being talked about I hear it about/the subject when people talk about statistics.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins the spinner 180 times. Kevin determines about how many times the spinner will land on red or green, and his work is shown below.

P (red or green) = Number of red or green sections
-------------------------------------------------- x number of spins =
Total number of sections
2
------- (180) = 36
10

What mistake did Kevin make, if any?

A. Kevin has the formula reversed; it should be the total number of sections over
the number of red or green sections.

B. Kevin should have used a 4 in the numerator because there are 2 red sections
and 2 green sections.

C. Kevin should multiply by the number of sections in the spinner rather than the
total number of spins.

D. Kevin calculated the prediction correctly and did not make any mistakes.

How do i write mixed numbers as an improper fraction?
Explain with examples.

Answers

Answer:

A mixed fraction can be written as an improper fraction by multiplying the whole number with the fraction's denominator and adding that to the numerator, and finally writing that result on top of the denominator.

Step-by-step explanation:

Answer:

You have to multiply the whole number by the denominator and then add the answer you get with the numerator.

Step-by-step explanation:

For example, the fraction 10 [tex]\frac{1}{3}[/tex] is a mixed number right? So then you multiply 10x3=30. Then you add 30+1=31. So then the answer would be [tex]\frac{31}{3}[/tex].

K + 1/4 = 5 1/8
It’s not 51 btw there’s a space

Answers

4.875because 5 1/8 = 41/8 - 1/4 = 4.875
K=4.875 or 4 7/8. First you use the inverse property and do 5 1/8 -1/4= 4.875.
The inverse property is just using the opposite sign like addition with subtraction and multiplication with division. You would use the opposite sign in this case the total.

Answer: 155in2

Step-By-Step explanation:

To find the area we had to split up the shape into parts. We also know that the formula for Area is Length x With . We split of the shape into 3 parts we will call them 1, 2, and 3
1: Area= L x W
1: Area = 7 x 6
1: Area = 42

2: Area= L x W
2: Area = 5 x (13+4)
2: Area = 85


3: Area= L x W
3: Area = 4 x ( 12-5)
3: Area = 28

now that we know all the areas for each shape we need to add them together.

42+85+28= 155in2

12. If four coins are flipped, find the probability of obtaining two heads and two tails.

Answers

Answer: 1/16 or 0.0625

Step-by-step explanation:

The probability of getting a heads is 1/2, and the probability of getting a tails is 1/2. To find the probability of getting 2 heads and 2 tails, multiply the probabilities of each event together. 1/2 * 1/2 * 1/2 * 1/2 = 1/16.

Carmen made punch with 34 gallon of orange juice, 2 quarts of strawberries, and 2 pints of lime sherbet. How many pints of punch did Carmen make? Use the diagram to help you solve. Explain.

Answers

Your answer will be 278 pints
1 GALLON = 8 PINTS
So, 3/4 gallon = 3/4 x 8 = 6 PINTS of ORANGE JUICE.

1 QUART = 2 PINTS
So, 2 QUARTS = 2 x 2 = 4 PINTS of STRAWBERRIES.

Given 2 PINTS of LIME SHERBET

Adding 6 PINTS + 4 PINTS + 2 PINTS = 12 PINTS

ANSWER: 12 PINTS

IF 2x3x4=24 then what is 6x4

Answers

if 2 x 3 x 4 = 24

Then 6 x 4 = 24 too

Answer:

24

Step-by-step explanation:

This can be explained very simply.

Case 1 : 2 x 3 x 4 = 24

Case 2 : 6 x 4 = ?

We know that the product of 2 x 3 is 6. Therefore, in Case 1 and Case 2, when both 2 x 3 and 6 are multiplied by 4, they should give the same result. Hence, 6 x 4 is 24.

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answers

Answer:

The point closest to the number 40

Step-by-step explanation:

To find volume of cone:

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

(but in this case we will be substituting [tex]\pi[/tex] for it approximation: 3.14)

So our new equation is [tex]V= 3.14r^{2} \frac{h}{3}[/tex]

All right, let's get to work now.

Following the order of operations our first step would be: [tex]3^{2}[/tex] or 3x3 wich is 9Next step would be 3.14x9, which is 28.26After that we would solve [tex]\frac{4}{3}[/tex], which is 1.3 repeating but we can round to the nearest tenth and get 1.3Next we would multiply 28.26 by 1.3 which is 36.73800

We would next round to the nearest whole and our final answer is: 37
