Samantha has 4 1/2 gallons of lemonade for her daughter’s birthday party. Each gallon of lemonade contains 1.5 grams of fat. How many grams of fat are contained in all the lemonade Samantha has for the party?

Answers

Answer:

6.75 grams

Step-by-step explanation:

Total amount of lemonade with Samantha =  4 1/2 gallons

         = (4*2 + 1)/2 gallons = 9/2 gallons = 4.5 gallons

Amount of fat in 1 gallon of lemonade = 1.5 grams

To find amount of fat in 4.5 gallons lemonade

we multiply both side of equation with 4.5

Amount of fat in 1*4.5 gallon of lemonade = 1.5*4.5  grams = 6.75 grams

Thus,

there is  6.75 grams of fat in  all the lemonade Samantha has for the party

10x - 2x in fewer terms is 8x.

What is Subtraction?

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given is an expression 10x - 2x.

We have to find the difference of these two expressions.

We can add or subtract only the like terms.

Like terms are terms which consist of same kind of variables.

Here 10x and 2x have same variable x.

So they can be subtracted.

10x - 2x = x(10 - 2) = 8x

Hence the difference of 10x and 2x is 8x.

Answers

Complete Question

In general,_______ % of the values in a data set lie at or below the 16th percentile.

_________ % of the values in a data set lie at or above the 24th percentile.

If a sample consists of 800 test scores, _______ of them would be at or below the 86th percentile. If a sample consists of 800 test scores,_______ of them would be at or above the 14th percentile.

Answer:

In general, 16 % of the values in a data set lie at or below the 16th percentile.

24 % of the values in a data set lie at or above the 24th percentile.

If a sample consists of 800 test scores,  688 of them would be at or below the 86th percentile. If a sample consists of 800 test scores, 688 of them would be at or above the 14th percentile.

Step-by-step explanation:

Generally percentile defines the percentage of a data set that is below or at a value that is being considered.

Hence the percentage of the values of a data set that lies below or at the 16th percentile is  16%

Also  the values of a data set that lies below or at the 24th percentile is  24%

Given a sample of 800 test scores , the number number of test scores that will be at or below the 86th percentile is 86% of  800 which is mathematically represented as

      [tex]k = \frac{86}{100} * 800[/tex]

        [tex]k = 6 88[/tex] test scores

Given a sample of 800 test scores , the number number of test scores that will be above  the 14th percentile is (100 - 14 = 86 )% of  800 which is mathematically represented as

       [tex]a = \frac{86}{100} * 800[/tex]

        [tex]a = 6 88[/tex] test scores
