[Problem 2]

-> Girls = 226

-> Boys = 295

-> Girls with glasses = 104

-> Boys with glasses = 210

-> Difference of total boys and girls = 69

-> Difference of boys with glasses vs without glasses = 85

-> Difference of girls with glasses vs without glasses = 122

-> It is hard to create a table over Brainly

[Problem 4] Answer is 4.3

-> To find the mean absolute deviation, we will find the mean of the data and then see how far away each point is, and then find the mean of those values

-> Finding mean: $\frac{38+46+52+44+47+55}{6}$ = 47

-> All the values (all of the values will be absolute values, why the word absolute is there, so ignore all negative signs!)

38 - 47 = 9

46 - 47 = 1

52 - 47 = 5

44 - 47 = 3

47 - 47 = 0

55 - 47 = 8

-> Then, we will find the mean of these values: $\frac{8+0+3+5+1+9}{6}$ = 4 $\frac{1}{3}$

-> 4 $\frac{1}{3}$ = 4.33333 and when rounded to the nearest tenth is 4.3

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Jesper can run 6 miles in 45 minutes. He is thinking about running in two different races, a 9-mile race and a 15-mile race. At

marin [14]

Find minutes per mile by dividing time by distance:

45 minutes / 6 miles = 7.5 minutes per mile

Now multiply his speed by each distance:

7.5 x 9 = 67.5 minutes

7.5 x 15 = 112.5 minutes

Now subtract the two:

112.5 - 67.5 = 45 minutes more

A bag contains 5 red marbles, 10 blue marbles, and 14 yellow marbles. If Jen selects a marble from the bag without looking, what

Darina [25.2K]

Answer:

The answer to your question is 0.83 or 83%

Step-by-step explanation:

Data

5 red marbles

10 blue marbles

14 yellow marbles

Process

1.- Calculate the total amount of marbles

Total amount = 5 red + 10 blue + 14 yellow

Total amount = 29 marbles

2.- Calculate the amount of marbles that are not red

No red marbles = 10 + 14

= 24 marbles

3.- Calculate the probability

Probability of not pulling a red marble = $\frac{no red marble}{total amount of marbles}$

Probability of not pulling a red marble = $\frac{24}{29} = 0.83 or 83%$

Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack.

sattari [20]

Answer:

Solutions: (2,10), (4,5)

Not solutions: (1,12), (6,10), (12,8), (18,6)

Step-by-step explanation:

Let x be the number of packages of pasta and y be the number of jars of pasta sauce. If pasta costs $1 for a 1-pound package, then x packages of pasta cost $x and weigh x pounds. If pasta sauce costs $3 for a 1.5 pound jar, then y jars cost $3y and weigh 1.5y pounds.

1. Tyler has $36, then

$x+3y\le 36.$
