solve in simplest form

15 3/5 - 3 2/7

Answer:

both of these are ways to kinda categorize numbers.

MEAN- you're finding the average. average and mean are synonymous. meaning they're the exact same. with the mean, all you have to do is add all the numbers up and then divide that by however many numbers you added up

lets say you need to find the mean of a domain and you're given this set of numbers:

{1,2,3,4,5,6,7}

the sum is 28. You divide it by 7 (bc thats how many numbers you added up) and you get your mean to be 4

The MEDIAN is going to be simpler than you may think. put all the numbers in numerical order, greatest to least or least to greatest. it doesn't matter.

Then find the number in the middle. Some people like crossing off the numbers on either end until you get to the center. So like marking off 1 then 7 then 2 then 6 etc.

The median is 4.

Step-by-step explanation:

Of course, I'm glad to help.

Mean is average. So for example, if I had the numbers 2,3,4, and 5 the mean would be 10.25.

The steps to getting mean are adding up all your numbers then dividing by the number of equalities you have.

Median is the middle number in your group. For example, if I had numbers 2, 3, 4, 5, and 6. The median would be 4 because that the number in the middle.

But when you have an even amount of numbers (for example 2,3,4,5) you'd add up the ones in the middle (3 and 4) then divide them by 2 (3+4=7/2). In this case, the median would be 3.5.

I know how hard school has been this year so it's understandable if you need help. You can always reach out to me in messages for more help.

Answer:

IJ=77

Step-by-step explanation:

[tex]\frac{35}{20} =\frac{IJ}{44}[/tex]

[tex]20IJ=1540[/tex]

[tex]IJ=77[/tex]

Answer:

THE ANSWER IS A. They have different y-intercepts but the same end behavior.

I used Desmos to graph the function g(x)=4(1/4)^x+2

They have different y-intercepts because function f(x) is 4, while the y-intercept on graph is 6

But they have the same end behavior at 2.

Step-by-step explanation:

Answer:

d = 34

Step-by-step explanation:

50 minus 16 equals 34, which means d must be equal to 34.

Answer:

D=34

Step-by-step explanation:

In order to find out what the value of d is, you need to subtract the total amount,50, from 16.

Therefore, D=34

Hope this helps :D

Answer:

x = 36º

Step-by-step explanation:

The sum of the angles in a triangle is 180º

x + 2x + 72 = 180

Combine like terms

3x + 72 = 180

Subtract 72 from both sides

3x = 108

Divide both sides by 3

x = 36º

Answer:

43.77°

Step-by-step explanation:

The height, h = first floor to basement = 9.2 feets

Length of staircase = hypotenus = 13.3 feets

Angle stacase makes with basement floor, θ

Using trigonometry :

Sinθ = opposite / hypotenus

Opposite = height = 9.2 feets

Sinθ = 9.2 / 13.3

Sinθ = 0.6917293

θ = sin^-1(0.6917293)

θ = 43.77°

Answer:

1. 0.75 cups or 3/4 cups

2. 0.75 cups or 3/4 cups

3. 10 quarts in 2 1/2 gallons

4. 3 3/4 or 3.75

5.  3/4 gallon

6.  2.5 sticks or 2 1/2 sticks

7. 1 3/5 pounds

8. 12 teaspoons

9.  12.5 or 25/2 I think

Answer:

Following are the solution to the question:

Step-by-step explanation:

[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]

z-score for [tex]\hat{p}=0.2[/tex] will be:

z score for will be:

[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]

[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Answer:

[tex]x = 0[/tex]

Step-by-step explanation:

Write the number in exponential form with the base of 2:

[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]

Since the bases are the same, set the exponents equals.

[tex]x - 3 = - 3[/tex]

Cancel equal terms on both sides of the equation:

[tex]x = 0[/tex]

[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]

To Find value of 'x'

[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]

Hi there!

A function is a set of ordered pairs that do not have same x-values.

In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.

From the question above, you notice that two of the choices have same x-values and others don't have.

The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.

Any questions can be asked through comment.

Furthermore, a function is also a relation but a relation isn't always a function.

Hope this helps, and Happy Learning! :)

Answer:

x=2

Step-by-step explanation:

4x-6=6-2x

(add 2x and 6 to both sides)

6x=12

(divide by six)

x=2

Double Check:

4(2)-6=2

6-2(2)=2

4(2)-6=6-2(2)

Answer:

x=2

Step-by-step explanation:

4x-6=6-2x

move the variables to right and constants to the left

4x+2x=6+6

combine like terms

6x=12

isolate x by dividing by 6 on both sides to find it's value

x=2

Answer:

9h

Step-by-step explanation

If Aaron makes 9 dollars per hour, then we can find out how much money he earned by doing the expression 9h, which means 9 dollars times h (the number of hours.)

Hope this helped!!! :)

Answer:

9h

Step-by-step explanation:

If he makes $9 an hour, and h represents how many hours he worked, the amount of money he made can be represented by 9h.

This will multiply $9 by how many hours he worked, giving us the total amount he made.

For example, if he works 2 hours, he will get $18.

So, the expression that represents how much he made yesterday is 9h.
