Answer:
78
Step-by-step explanation:
in a quadrilateral that's inscribed in a circle, opposite angles are supplementary.
102+78=180
K = 4pq^2
k/4p = q^2
0.5(k/p)^1/2 = q
A set of data has a normal distribution with a mean of 5.1 and a standard deviation of 0.9. Find the percent of data between 4.2 and 5.1.
Answer: The correct option is B) about 34%
Proof:
We have to find
To find , we need to use z score formula:
When x = 4.2, we have:
When x = 5.1, we have:
Therefore, we have to find
Using the standard normal table, we have:
=
or 34.13%
= 34% approximately
Therefore, the percent of data between 4.2 and 5.1 is about 34%
Answer:
last one
Step-by-step explanation:
x = width
x+6 = length
Area = length times width
x(x + 6) = + 6x
+ 6<em>x = 114 (subtract 114 from both sides) </em>
<em /><em> + 6x -114 = 0</em>
