What is the average of -2.5, 5.2, 1.7, and -0.8.
Answer:
0.9
Step-by-step explanation:
-2.5 + 5.2 + 1.7 + -0.8 = 3.6
Divide by the total count of numbers
= 0.9
Hope this helps!
Answer:
0.9
Step-by-step explanation:
To find the average or mean, you have to add up all the given numbers in your data set, then divide by how many numbers there are.
1. Add up -2.5 + 5.2 + 1.7 + (-0.8)=
(negative times positive equals negative)
simplify the signs
simplified answer= -2.5+5.2+1.7-0.8
Which equals
3.62. divide by how many numbers there are
So take 3.6 and divide it by 4.
why the number 4?
well, there are 4 numbers in the data set. so when you calculate the average, the formula would be to add up all the numbers in the data set and divide by how many numbers are in the data set and there are 4 numbers in the data set.
So... 3.6 divided by 4
is...
0.9The average is 0.9

Answer:
[tex]\bold{3 < (y - 2)} \\ \bold{y > 3 + 2} \\\bold{ y > 5}[/tex]
hope helpful~
Answer:
3 is less than y minus 2 => 3 < y - 2
Step-by-step explanation:
If an expression has an equal sign, it is called an equation.
If it has less than or greater than sign, then it is called inequality.
It is also an inequality if it has greater than or equal to or less than or equal to signs. ( ≥, ≤).
Now y minus 2 means
y - 2
Now it says 3 is less than (y-2)
So we get
3 < y - 2

Elisabeth reads 1/5 of her book in 1 1/2 hours. Elisabeth continues to read at this pace. How long does it take Elisabeth to read 3/4 of the book? Enter your answer as a mixed number in simplest form by filling in the boxes.
It will take her 5 5/8 hours to read 3/4 of the book
Ratio and proportions
Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:
0.2 of a book = 1.5 hours
In order to determine the time taken to read 0.75 part of the book, we will have:
0.75 of a book = x
Take the ratios
0.2/0.75 = 1.5/x
0.2x = 1.125
x = 1.125/0.2
x = 5.625
Hence it will take her 5 5/8 hours to read 3/4 of the book

14.) A beverage company packed 228 cans of soda in 12-can cases. How many cartons were filled?
Answer:
Step-by-step explanation:
Round to the nearest ten, hundred, or thousand:
1. 6,471 to need to the nearest thousand is 6,000
Estimate each sum, difference, or product by first rounding to the nearest hundred.
2. 41,348 + 19,749 ==> 41,300 + 19,700 = 61,000
3. 38,652 - 14,549 ==> 38,700 - 14,500 = 24,200
4. 396 • 748 ==> 400 • 700 = 280,000
Solve the equations:
5. t + 28 = 5
- 28 -28
t = 26
6. 28x = 168
/28 /28
x = 6
7. 27 = y + 12
-12 - 12
15 = y or y = 15
Simplify:
8. 10 • 24 - (18 + 2) ÷ 4 - (9 - 7)

12. Natasha has $196 and wants to buy a computer for $698. How much more do you need?
698 - 196 = $502 <== final answer
13. Toni has $406 in her checking account. He is paid $78 for a part-time job and deposits it into his checking account. What is the balance in your account now?
406 + 78 = $484 <== final answer
14. A beverage company packed 228 cans of soda in 12-can cases. How many cartons were filled?
228/12 = 19 cartons filled <== final answer
Hope this helps!
1. 6,471 rounded to the nearest thousand is 6,000.
2. 41,348 rounded to the nearest hundred is 41,300, and 19,749 rounded to the nearest hundred is 19,700. Their sum rounded to the nearest hundred is 61,000.
3. 38,652 rounded to the nearest hundred is 38,600, and 14,549 rounded to the nearest hundred is 14,500. Their difference rounded to the nearest hundred is 24,100.
4. 396 rounded to the nearest hundred is 400, and 748 rounded to the nearest hundred is 700. Their product rounded to the nearest hundred is 280,000.
5. Subtracting 28 from both sides of the equation, we get t = 26.
6. Dividing both sides of the equation by 28, we get x = 6.
7. Subtracting 12 from both sides of the equation, we get y = 15.
8. 10 • 24 = 240. 18 + 2 = 20. 20 ÷ 4 = 5. 9 - 7 = 2. Therefore, the expression simplifies to:
240 - 5 - 2 = 233.
9. First, we need to evaluate the expressions inside the parentheses:
56 ÷ 8 = 7
8 • 8 = 64
5 • 5 = 25
20 - 7 = 13
64 - 25 = 39
Substituting these values into the expression, we get:
80 ÷ 16 x (13 + 39) = 5 x 52 = 260.
10. 5 to the power of 4 is 5 x 5 x 5 x 5, which equals 625.
11. 6 cubed is 6 x 6 x 6, which equals 216.
12. Natasha has $196 and needs $698 for a computer. To find out how much more she needs, we subtract the amount she has from the amount she needs:
698 - 196 = 502.
Natasha needs $502 more to buy the computer.
13. Toni's new balance in his checking account is the sum of his original balance and his new deposit:
406 + 78 = 484.
His new balance is $484.
14. The beverage company packed 228 cans of soda in 12-can cases. To find out how many cartons were filled, we divide the total number of cans by the number of cans in each case:
228 ÷ 12 = 19.
The company filled 19 cartons.
