Solve the following equation:<br> 2|3x - 2| -4 = 16
bulgar [2K]

Answer:

x=6 and -14/3

Step-by-step explanation:

Divide 2:

|3x - 2|-4 = 16

Plus 4: |3x - 2| = 16

So 3x - 2=16 and -3x + 2=16

3x - 2=16: x=6

-3x + 2=16: x=-14/3

Tems11 [23]

Answer:

area of circle=pi times radius^2

diameter/2=radius

area of rectangle=length times width

rectanlge-circle=scarf

rectanlge=28 by 15=28*15=420

circle, diameter is 15 so radius is 15/2=7.5

area=pi7.5^2=pi56.25=3.14*56.25=176.625

so

rectangle-circle=420-176.625=243.375 square inches

the area of the scarf is 243.375 square inches

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
dexar [7]

Given

Expenditures at Manager's Store; expenditures at Competitor's Store.

Find

a) average spent at each store

b) which store is better represented by the mean value

c) an explanation for the answer in ≥ 2 sentences

Solution

a) The sum of expenditures divided by the number of expenditures (15) is ...

... average for Manager's Store: $37.60

... average for Competitor's Store: $48.53

b) The expenditures at Manager's Store are well-represented by the mean (average).

c) The range of expenditures at Competitor's Store is significantly higher than at Manager's store, so a single number such as mean or median does not represent the data well. The expenditures at Manager's store are more compactly grouped around the mean and median, which are closer together, so the mean is a good representation of Manager's Store expenditures overall.
