The area of a rectangle is A=lw. Therefore, it can be represented here as: A=(4ab^2)(2ab).
Now, you can distribute.
4*2=8
a*a=a^2
b^2*b=b^3
The simplified expression is 8a^2b^3.
Hope this helps!!
The mean remains the same
The two triangles are congruent through AA (angle-angle proportionality theorem) therefore all the sides are congruent to each other.
In this case:
2y = 5y - 7
2y - 5y = -7
-3y = -7
y = -7/-3
y = 7/3
Answer:
Step-by-step explanation:
Answer: 84.61%
Explanation.
Refer to the diagram shown below.
When the z-score is z = 0, then the area under the distribution curve is 50%, which corresponds to the mean, μ.
The given z-score is greater than zero, so the shaded area is 34.61%. to the right of z=0
The area to the left of z = 1.02 is 50% + 34.61% = 84.61%.
This percentage represents the people with IQs at or lower than Atfif's score.
