Answer:
-3y
Step-by-step explanation:
-15(y2)4 ÷5y3y4
Rewrite the division as a fraction
<u>-15(y2)4</u>
5y3y4
Multiply y3 by y4 by adding the exponents
<u>-5(y2)4</u>
5y7
Cancel the common factor of -15 and 5
<u>-3(y2)4</u>
y7
Multiply the exponents in (y2)4
<u>-3y8</u>
y7
Cancel the common factor of y8 and y7
Factor y7 out of -3y8
<u>y7(-3y)</u>
y7
Multiply by 1
<u>y7(-3y)</u>
y7 × 1
Cancel the common factor which is y7 and y7
Rewrite the expression
<u>-3y</u>
1
Divide -3y by 1
-3y
Answer:
b
Step-by-step explanation:
a x (b + c) = (a x b) + (a x c)
Answer:
I can only do mean and median
First, you have to write it in decreasing order
1, 4, 5, 6,7,8,9,9,9,11
Now, we seperate them
1, 4, 5, 6,7,8,9,9,9,11
the two middle numbers are 7 and 8 so the median is 7.5
upper quartile: 8,9,9,9,11
lower quartile: 1, 4, 5, 6, 7
To find the mean, we have to add all the numbers and divide it by the amount of numbers. There are 10 numbers and added togetehr they are 69 so divide 69 by 10 so 6.9 for the mean and 7.5 for median
