The answer would be
•“The manager should check both relative frequencies by row and by column to look for an association.”

This is because the manager wants to know whether a customer buys more than $30 worth of stuff at their store with coupons taking off a lot or a little bit of the price.

If you want please mark BRAINLIEST.!
Hope this helps! :)

Answer is B.

We see the center lines are 80 and 85 as stated.

A is wrong because the range of class 2 is less.

C is wrong; class 2 has a minimum of 50

D is wrong; class 2 has a smaller interquartile range, which is the width of the boxes.

Rachel has an 80:1 scale drawing of the floor plan of her house. On the floor plan, the dimensions of her rectangular living roo
Allushta [10]

Answer:

208⅓ ft²

Step-by-step explanation:

The dimensions of Rachel's living room are 80 times the measurements on the scale drawing.

Calculate the width:

                                                                                     w = 80 × 1⅞

Convert the mixed number to an improper fraction     = 80 × 15/8

Cancel the 8s                                                                  = 10 × 15

                                                                                        = 150 in

Convert inches to feet                                                   = 150/12  

Convert the improper fraction to a mixed number      = (144 + 6)/12

                                                                                        = 12⁶/₁₂

Reduce the fraction to lowest terms                             = 12½ ft

Calculate the length

l = 80 × 2½  = 80 × 5/2 = 40 × 5 = 200 in = 200/12 = (192 + 8)/12

l = 16⁸/₁₂ = 16⅔ ft

Calculate the area

A = lw

A = 16⅔ × 12½

Convert the mixed numbers to improper fractions

A = 50/3× 25/2

Cancel the 2s

= 25/3 × 25

Multiply numerators and denominators                        

= 625/3

Convert the improper fraction to a mixed number    

= (624 + 1)/3

= 208⅓ ft²

The area of Rachel's living room is 208⅓ ft².

The cost of 4 kilograms of cheese is 50 dollars. which equation shows this in function notation?
Xelga [282]
$50 corresponds to 4 kg That means there must be a number that when you multiply by 4 you get 50. Let that number be k. k is the price of cheese per kg. 1 kg: y = k * 1 2 kg: y = k * 2

Dwayne has $5.00 kendra has 1/10 as much money as dwayne juan has 1/10 as much money as kendra tom has 10 times as much money as
Paha777 [63]
To answer this question you need to interpret the ratio of the money correctly. We only know Dwayne money, so it's better to solve the ratio which was related to Dwayne. In this case, it was Kendra or Tom. 

Dwayne money = $5
Kendra money= 1/10 Dwayne money= 1/10 x $5= $0.5
Juan money= 1/10 Kendra money = 1/10 x $0.5= $0.05
Tom money = 10 x Dwayne money = 10 x $5 = $50
Ruth money = 10 x Tom money = 10 x $50= $500
