Answer 1

Answer:

The correct answer is:

Sydney should choose the median after dropping one test score.

Step-by-step explanation:

when scores are not dropped:

List of scores = 68%, 84%, 94%, 100%

Mean = (68 + 84 + 94 + 100) ÷ 4 = 86.5%

Median = 68  84  94  100

Median = (84 + 94) ÷ 2 = 89%

Although there are no outliers because Sydney was given the option to drop a test score, dropping the lowest score will increase his overall chances of making a higher score. Therefore, 68% will be dropped.

List of scores when the lowest score is dropped  = 94%, 84%, 100%

Mean: (84 + 94 + 100) ÷ 3 = 92.7%

Median: 84, 94, 100

Median = 94% (middle term)

From  the four possible scores, the highest score is 94%, and it is gotten by finding the median after dropping a score

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is is given as

The fraction of bookshelf Kiki painted on Monday = 1 / 5

The fraction of bookshelf Kiki painted on Tuesday = 5 / 6

Now , the equation will be

Therefore , the total bookshelf Kiki painted is = fraction of bookshelf Kiki painted on Monday + fraction of bookshelf Kiki painted on Tuesday

Substituting the values in the equation , we get

The total bookshelf Kiki painted is = 1/5 + 5/6

The total bookshelf Kiki painted is = 11/30

Therefore , the value of A is 11/30

Hence , The total bookshelf Kiki painted is 11/30
