100 POINTS PLEASE HURRY Brianna solved a two-step equation, but she made a mistake along the way.

0.1x + 3 = 1.7
(-3) + 0.1x + 3 = 1.7 + (-3) Line 1
0.1x = -1.3 Line 2
(-0.1) + 0.1x = -1.3 + (-0.1) Line 3
x = -1.4 Line 4
What mistake did Brianna make?
On Line 1, Brianna should have subtracted 3 instead of adding -3.
On Line 1, Brianna violated the addition property of equality.
On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.
On Line 3, Brianna violated the addition property of equality.

Have a good day.

The order is  Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given, table shows the portion of votes each candidate get,

Nominees             Voting Portion

Mr. Douglas             9/50

Mrs. Maury                26%

Mr. Hill                       7/20

Mrs. Jackson              0.21

converting the votes in equal ratio,

Mr. Douglas  =   9/50 votes

multiply and divide by 2

Mr. Douglas  =   9 x2/50 x 2 = 18/100

Mrs. Maury =  26% = 26/100

Mr. Hill = 7/20

multiply and divide by 5

Mr. Hill = 7 x 5/20 x 5 = 35/100

Mrs. Jackson  = 0.21 = 21/100

Mr. Hill is winner with most number of votes.

Hence the order beginning with winner is Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The given statement "A data set can have more than one median" is False.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median; It represents the middle value of the given data when arranged in a particular order.

Mode; It is that number that appears most frequently in the given set of data.

Given the statement as; A data set can have more than one median.

If the value changed is not the middle value (if number of observations are odd) or is not changing the average of two mid values (if number of observations are even), then the median won't change as it does not care about the value of the data unless its about the mid value of the sorted data or average of mid values.

Since the median and mean can only have one value for a given data set. The mode can have more than one value

The given statement is False.

Answer:

$16.50

Step-by-step explanation:

If we divide $66 by 4 (pizzas), we get 16.5 and we add a zero on the end to make it a value in money

Answer:

I don't know but this might be helpful add and multiply the numbers they give you and divide by 12%

Step-by-step explanation:

The amount of money Kevin earn = $ 232.60

The amount of money Kenneth earn = $ 207.12

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 amount of money Kevin earn = A

Let the amount of money Kenneth earn = B

Salary of Kevin = $ 135

Salary of Kenneth = $ 135

Now , the equation will be

Ratio of Kevin's and Kenneth's commission be = a : b

The value of a : b = 3 : 4

Now , Kevin earns 12 percentage commission

So , the value of a = 12 %

So , the commission earned by Kenneth b = 12 x ( 4 / 3 )

The commission earned by Kenneth b = 16 %

Now , the total amount of products sold by Kevin and Kenneth = $ 610 each

So , the commission of Kevin a = ( 12/100 ) x 610

The commission of Kevin a = $ 73.20

And , the total earning of Kevin = amount of Kevin's salary  + commission of Kevin a

Substituting the values in the equation , we get

The total earning of Kevin A = 135 + 73.2

The total earning of Kevin A = 207.12

Now ,

The commission earned by Kenneth b = ( 16/100 ) x 610

The commission earned by Kenneth b = $ 97.60

The total earning of Kenneth B = amount of Kenneth's salary  + commission of Kenneth b

Substituting the values in the equation , we get

The total earning of Kenneth B = 135 + 97.60

The total earning of Kenneth B = $ 232.60

Therefore , the value of A is $ 207.12 and the value of B is $ 232.60

Hence ,

The amount of money Kevin earn = $ 232.60

The amount of money Kenneth earn = $ 207.12
