Step-by-step explanation:
Z -2.02
x 10
µ 22.5
σ 6.2
Answer:
14cm
Step-by-step explanation:
To find volume, you need to multiply the height width and length together. So when you have one missing measurement, to find it, you need to do the same steps except for put a variable for the missing measurement. And continue to do the problem as you would. Here is how I solved it.
V=12x18xH
3024=216xH (216 is 12x18)
Then to find the missing side, do 3024/216 which equals 14.
Option D:
The dimensions of the matrices don't align properly to find their sum.
Solution:
Given data:
Dimension of matrix = Number of rows × Number of columns
Dimension of matrix is 2 × 1
Dimension of matrix is 2 × 2
Here, we have to add the two matrices.
<em>The dimension of the matrices must be same to add or subtract matrices.</em>
Here the dimensions are 2 × 1 and 2 × 2.
The dimensions are not same.
Hence we can't find their sum.
Option D is the correct answer.
The dimensions of the matrices don't align properly to find their sum.
-120 ÷ 15 = -8.
Hope this helps.
