Answer:
A
Step-by-step explanation:
If you simplify the equation you are left with 5 = -1, which is an untrue statement. Therefore, no matter what value you use for x you will always be left with 5 = -1.
Complete Question:
Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.
Part A= 12 x ? = ? ft²
Part B= 0.5 x ? x 9 = ?ft²
Part C= 0.5 x 7 x ? = ?ft²
Total Area= ?ft²
Answer:




Step-by-step explanation:
Given
See attachment
From the attachment;
Part A is a rectangle with dimension 9ft by 12ft
So,


Part B is a triangle with dimension: height = 6 and base = 9
The height is calculated as:

And the base is:

So, the area is:


Part C is a triangle with dimension: height = 7 and base = 7
So, the area is:


Total Area is:

Answer:
41.92%
Step-by-step explanation:
In table attached standard normal distribution curve is shown.
Data
mean, µ = 4.3 minutes
standard deviation, σ = 0.5 minutes
desired point, x = 5 minutes
x-axis, Z = (x - µ)/σ
The probability that calls last between 4.3 and 5.0 minutes is equivalent to find the area below the curve between Z = 0 and Z = (5 - 4.3)/0.5 = 1.4, which is 0.4192, or 41.92%
Answer:
66 I am pretty sure
Step-by-step explanation:
6 x 2 divided by 2 = 6
