Answer:
The Average Temperature for the week is -1°C
Step-by-step explanation:
First to find the average, you have to combine all the numbers
-3-4+0-2+0+3-1 = -7
Then you have to divide the total, with the number of numbers used to combine to make the total
-7 ÷ 7 = -1
The average temperature is -1°C
Answer: Red is 0.18 And Blue is 0.68
Step-by-step explanation:
Look at sizes and comparisons between the sizes and all together should add to 1
Given u/7 - 1 = 7 and plugging in values for u,
For u = 28; 28/7 - 1 = 4 - 1 = 3; No
For u = -49; -49/7 - 1 = -7 - 1 = -8; No
For u = 42; 42/7 - 1 = 6 - 1 = 5; No
For u = 0; 0/7 - 1 = -1; No
Another way to find out which value would be a solution to u/7 - 1 = 7 is to solve for u.
u/7 - 1 = 7
u/7 = 7 + 1
u/7 = 8
u = 8*7
u = 56
The only solution to this equation is when u = 56.
