Answer:

Fractions have different applications in the real word. We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie. They can also be interpreted as decimals and percentages.

Step-by-step explanation:

Hope this helps!

All the correct methods to interpret fractions is,

Fractions as parts of wholes or parts of sets;

Fractions as the result of dividing two numbers;

Fractions as the ratio of two quantities;

Fractions as operators; and fractions as measures.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

To find the method for interpret fractions.

Since, Fractions have different applications in the real word.

Hence, We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie.

And, They can also be interpreted as decimals and percentages.

Answer: 21

Step-by-step explanation:

[tex]N-\left(2\cdot \:7\right)=7[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]

[tex]N-2\cdot \:7=7[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:2\cdot \:7=14[/tex]

[tex]N-14=7[/tex]

[tex]\mathrm{Add\:}14\mathrm{\:to\:both\:sides}[/tex]

[tex]N-14+14=7+14[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]N=21[/tex]

Answer:

N = 21

Step-by-step explanation:

N - (2 × 7 ) = 7                                {2 × 7 = 14}

N - 14 = 7

   + 14   +14

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

N = 21

Now we can substitute:

21 - (2 × 7 )

21 - 14 = 7

Hence, the answer is N = 21

Step-by-step explanation:

To find the constant of proportionality between y and x, divide  [tex]\frac{y}{x}[/tex] for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.

Using the method above, you should get:

Chart A = 2/5

Chart B = 1/5 (Correct Answer!)

Answer:

c)12

Step-by-step explanation:

since on the bar graph 12 occurs the most that is the mode so hope this helps!

The mode of the daily data is 12 cups.

A skewed distribution is a distribution having bias on one of the two sides (either left or right).

It is like leaning mountain on one side (left or right).

A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph. This graph usually has mean < median < mode.

A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph. This graph usually has:

Mode < median < mean.

We are given that;

The bar graph show 8cups on monday, 12 cups on tuesday, 10 cups on wednesday, 16 cups on thrusday, 12 cups on friday, 14 cups on saturday and 18 cups on sunday.

Now,

The mode of a set of data is the value that occurs most frequently.

Looking at the bar graph, we can see that the values 8, 10, 12, 14, 16, and 18 all occur once, but only one value occurs more than once, which is 12 cups on Tuesday and Friday.

Therefore, by skewed distribution the answer will be 12.

Step-by-step explanation:

12x - 6 = 10

divide both sides by 2

6x - 3 = 5

Answer:

There are four red marbles and six blue marbles in all, for a total of ten marbles.

Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.

The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.

Since gravity falls at a rate of 16 feet per second, t= number of seconds.

if t=2 seconds, you would have the equation 16*2 = fall amount

16*2 =32. Since it is less than 60 feet, the backpack won't hit the ground in 2 seconds

Answer:

D) None of the above

Step-by-step explanation:

Let's use process of elimination!

A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.

B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.

C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.

D) None of the answers above are correct.

Answer: Lonnie’s Jump

Step-by-step explanation:

         (They just had to give three names that all started with L.)

         Since Lenny's jump is ⅔ times the length of Lainey’s, we can tell that Lenny's jump won't be the longest because it is already smaller than Lainey's.

         Since Lenny is now out of the picture, let us look at Lonnie and Lainey. Lonnie’s jump is 1 ⅓ times the length of Lainey’s. Since Lonnie's jump is longer than Laniey's, Lonnie's jump is the longest jump.

Your answer is 18 ° and 162 °

Step-by-step explanation:

All you need to do is subtract the number you're given from 180.

Answer:

9 and 171 degrees

Step-by-step explanation:

Let the first unknown angle be x.  Then the second is x + 162 degrees.  Then, since supplementary angles sum up to 180 degrees,

x + x + 162 degrees = 180 degrees, or

2x = 18 degrees.  Therefore the first angle is 9 degrees and the second is 171 degrees.

Step-by-step explanation:

To do this you need to simplify (4^3)^5

To do this, simply multiply the powers

So, it would be 3x5

3x5=15

so the answer would be 4^15, which is D

Answer:

4^15

Step-by-step explanation:

( 4^3 )^5

Formula : -

( a^m )^n = a^(mn)

Here,

a = 4

m = 3

n = 5

( 4^3 )^5

= 4^( 3*5 )

= 4^15
