the answer is 7.4
To find the mean, you add all of the numbers together and divide by the amount of numbers added.
1. 2. 3. 4.
ex: 3+6+7+10=26. there are four numbers before the equal sign.
So the mean is 26÷4 or 6.5
since there are 5 total numbers, and all of the numbers added equal 37, then divide by 5, which will equal 7.4
Bob ust choose a shirt and a pair of pants for today's outfit. He has 2 shirts and 3 pairs of pants to choose from how many different outfits can he make.
Answers
Answer:
6 outfits.
Step-by-step explanation:
Bob has 2 shirts and 3 pairs of pants. That means he can wear one of the two shirts with any of the three pants (which'd make 3 outfits) and then with the other shirt with any of those three pants again (which'd make another three outfits.
Since you want to find out how many outfits Bob can make using the five articles of clothing, therefore 3+3=6 and 6 outfits would be your answer.
If you want to think of this problem another way, in simpler terms you can think of it like this: 2*3=6. Two shirts times three pants, which equals to six that makes our answer Bob can make six different outfits from his options above.

Answers
Answer:
(a) The system of equations that could be used to find the length (in hours) of each type of workout is:
- Equation 1: 3x + 5y = Total hours on Friday
- Equation 2: 5x + 7y = Total hours on Saturday
where x is the length (in hours) of each Plan A workout and y is the length (in hours) of each Plan B workout.
(b) To find the length of each type of workout, we need to know the total hours that Susan trained on Friday and Saturday. Once we have that information, we can solve the system of equations using either the substitution or elimination method.
(c) To find the length of each type of workout, we can either solve the system of equations ourselves or use a calculator or online tool (like Wolfram Alpha) to solve it for us. Once we have the solution, we can plug it back in to the equations to make sure it works.
For example, if the total hours on Friday were 12 and the total hours on Saturday were 18, the solution would be:
- x (Plan A) = 2 hours
- y (Plan B) = 4 hours
And plugging it

Koharu bought a bag of fruits.
The total weight of the fruits was `1` pound.
What could she have bought?
Answers
Koharu could have bought a variety of fruits that add up to 1 pound in weight. Some examples of fruits and their approximate weights per piece are:
- Apples: 1 large apple = 0.5 pounds
- Bananas: 1 medium banana = 0.3 pounds
- Oranges: 1 medium orange = 0.3 pounds
- Grapes: 1 cup of grapes = 0.5 pounds
- Strawberries: 1 cup of strawberries = 0.3 pounds
- Blueberries: 1 cup of blueberries = 0.3 pounds
So Koharu could have bought a combination of these fruits that adds up to 1 pound in weight. For example, she could have bought 2 large apples (1 pound), or 3 medium bananas and 2 medium oranges (1.2 pounds), or 2 cups of grapes and 1 cup of blueberries (1.3 pounds), and so on.
Answer:She could have bought a cantaloupe
Step-by-step explanation: a cantaloupe weighs 16 oz and 16 oz equals 1 pound

Deena works at a customer service call center. She fields an average of 6 calls per hour. Employees are encouraged to field more than 240 calls per week. Deena has already fielded 120 calls this week. How many more hours,x , does Deena need to work this week to reach the weekly goal of fielded calls?
A. x>20
B. x>40
C. x>26
D. x>2
Answers
Step-by-step explanation:
Deena's goal is to take 200 calls this week.
She already answered 85 calls this week, so she's missing 115 (200-85) calls for her goal.
She takes about 5 calls per hour, so how many hours does she need to work more?
h = 115 calls / (5 calls/h) = 23 hours
So, she needs to work at least 23 more hours... so x > 23.

The salaries of three employees are listed below. Each employee was recently given a raise.

John $43,400 4.5%
Jack $39,400 3%
What is the total of all three raises?
A. $4,775
B. $14,237
C. $4,704
D. $10,523
Answers
Step-by-step explanation:
Don't worry we will take care of everything. It's easy. listen carefully
1. we know the salary of each employee, before raise. and also their raise %age.
2. CONCEPT:- FOR EMPLOYEE (JANE) -
AMOUNT RAISED ON HER SALARY= 4% of $41000
= ( 4/100)× 41000
= $1640 (this is the raised amount in jane original salary)
3. similarly , you can also find raised amount for jhon and jack which will be $1953 and $1182 respectively.
4. for final solution, you just have to add all the raised amount in their original salary. hence final solution will be
= $1640 + $1953 + $1182
= $ 4775 (final solution).
