Answer:
15.1 to nearest tenth.
Step-by-step explanation:
The 7 is the lowest number so the mean would increase if taken away.
New mean = (8 + 12 + 13 + 15 + 18 + 19+21) / 7
= 106 / 7
= 15.14
Answer:Volume = 108 cm ³
Explanation:For a square pyramid, the volume can be calculated as follows:
Volume =

* area of base * height
Volume =

* side² * height
We have:
side length = 6 cm
height = 9 cm
Therefore:
Volume =

* 36 * 9 = 108 cm ³
Hope this helps :)
2.26 > 2 2/5 > 2.62 > 26.8 > 271
I got 168 because if you multiply 8x12 then you would get 96 and on the sides u need to multiply 3x12
Answer:
(-7, -3)
Step-by-step explanation:
Do it in two steps:
a) First mirror point (7,3) in x-axis gives (7, -3).
Then the next step...
b) ...mirror point (7, -3) in y-axis gives (-7, -3)
Please understand that the outcome is the same, if you first mirror in y-axis and then mirror in the x-axis.
Just to demonstrate this:
a) If you irst mirror point (7,3) in y-axis gives (-7, 3).
Then the next step...
b) ...mirror point (-7, 3) in x-axis gives (-7, -3)
