Answer:

The average of the John scores is 84.75.

Step-by-step explanation:

Formula of average is given as :

A=\frac{\text{Sum of all the terms}}{\text{Number of terms}}

We have:

Test grades of John: 82, 93, 75, and 89

Number of terms - 4

Average of the score of the John;

a=\frac{82 + 93 +75 + 89}{4}=84.75

The average of the John scores is 84.75.

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.

HOPE THIS HELPS!!

Answer:

4) 12 different calzones

5) 15 ways

6) 8 outfits

Step-by-step explanation:

When counting the total number of combinations like these situations, multiply the number of choices of each type together

For 4: 3 sizes, times 4 fillings, is 12 different calzones

For a small calzone, there are 4 diffferent fillings to choose from, making 4 calzones,

For a medium calzone, there are 4 differnt fillings, making 4 more for a total of 8,

For a large calzone, there are 4 different fillings, making 4 more for a total of 12

The same logic applies to the other problems

3x + 4y = 24<br> 6x + 8y = 24 using process of elimination
Lelechka [254]

Answer:

false

Step-by-step explanation:

3x+4y=24 multiplied by 2 equals: 6x+8y=48

if you subtract 6x+8y=24 from 6x+8y=48, you get 0=24, which is not true. Therefore the statement is false.

Admission to the country fair is $4.50 tickets for the rides are $0.50 each
tester [92]
So first, she has $11.00

Then, she has to pay an entry fee of $4.50

$11.00 - $4.50 = $6.50

If the rides are $0.50 each, divide $6.50 by $0.50

$6.50/$0.50=13

She could purchase 13 tickets for the rides.
