Answer:

x = 26.4 y= 17

Step-by-step explanation:

Set up proportions.

To find x:

Set 12 over x is equal to 10 over 22.

12 times 22 = 264

264 / 10 =x

x = 26.4

To find y:

Set y over 37.4 is equal to 10 over 22.

37.4 times 10 = 374

374 / 22

y = 17

2-31 The following grade-point averages apply to a random sample of graduating seniors. 3.812.732.513.093.28 3.512.861.203.133.2

Dmitry_Shevchenko [17]

Answer:

The sample range is 2.61.

Step-by-step explanation:

We are given the following grade-point averages which apply to a random sample of graduating seniors below;

3.81, 2.73, 2.51, 3.09, 3.28, 3.51, 2.86, 1.20, 3.13, and 3.24.

As we know that the range of the data is calculated bu using the following formula;

Range = Highest value in the data - Lowest value in the data

Here, Highest value = 3.81

Lowest value = 1.20

So, the sample data range = 3.81 - 1.20

= 2.61.

Mateo has 72 pounds of apples. He needs 34 pounds of apples for each batch of applesauce. How many batches of applesauce can Mat

mr Goodwill [35]

Answer:

2 batches

Step-by-step explanation:

(72 lb)/(34 lb/bat) = 2 2/17 bat

___

72 ÷ 34 = 2 remainder 4.

Mateo can make 2 full batches, and will have 4 pounds of apples remaining.

The fraction 4/34 can be reduced to 2/17. That is the fraction of a batch that Mateo could make with the extra 4 lbs. of apples.

: Sam is 12 years older than John. For the last four years, Sam and John have been friends. Five years ago, Sam was 5 times as o

Firlakuza [10]

Answer:

The present age of Sam is 20 years .

Step-by-step explanation:

Given as :

Let The age of John = J years

Let The age of Sam = S years

∵ Sam is 12 years older than John

so, The age of Sam = 12 + The age of John

i.e S = 12 + J .....1

<u>Again</u>

Before 5 years ago

The age of Sam = 5 times age of John

So, (S - 5) = 5 × (J - 5)

Or, S - 5 = 5 J - 25

Or, 5 J - S = 25 - 5

Or, 5 J - S = 20 .........2

Solving eq 1 and eq 2

[5 J - (12 + J)] = 20

Or, 5 J - 12 - J = 20

Or, 4 J = 20 + 12

Or, 4 J = 32

∴ J = $\frac{32}{4}$

i.e J = 8 years

So, The age of John = J = 8 years

Put The value of J into eq 1

∵ S = 12 + J

So, S = 12 + 8

i.e S = 20 years

So, The present age of Sam = S = 20 years .

Hence, The present age of Sam is 20 years . Answer
