Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
39 x 5 = (30 x 5) + (9 x 5) = 150 + 45 = 195
He did not change the sign of operation when 28 crossed the equals sign.
Answer:
see explanation
Step-by-step explanation:
6 × 24 ← replace 24 by 4 + 20
= 6(4 + 20) ← multiply each term in the parenthesis by 6
= 24 + 120
= 124
Answer:
Step-by-step explanation:
From the information given:
For Adult Men
Mean
= 69.5
Standard deviation
= 2.4
observed value X = 74
For Adult Women
Mean
= 63.8
Standard deviation
= 2.6
observed value X = 70
Therefore ; the values for their z scores can be obtained in order to determine who is more unusually tall within his or her respective sex
For Adult Men :
![z = \dfrac{X- \mu}{\sigma}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7BX-%20%5Cmu%7D%7B%5Csigma%7D)
![z = \dfrac{74- 69.5}{2.4}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B74-%2069.5%7D%7B2.4%7D)
![z = \dfrac{4.5}{2.4}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B4.5%7D%7B2.4%7D)
z = 1.875
For Adult Women :
![z = \dfrac{X- \mu}{\sigma}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7BX-%20%5Cmu%7D%7B%5Csigma%7D)
![z = \dfrac{70- 63.8}{2.6}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B70-%2063.8%7D%7B2.6%7D)
![z = \dfrac{6.2}{2.6}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B6.2%7D%7B2.6%7D)
z = 2.3846
Thus; we can conclude that , the women is more unusually tall within his or her respective sex
Yes, they are the same slope because the line is straight so it has no edges.
I think
But this is my work and i explained it
HOPE THIS HELP YOU!!!
