The answer to your question is D.
Answer:
x = -7
Step-by-step explanation:
Our function is
. Notice that our possible roots are when x + 4 = 0 and when x + 7 = 0. So, our roots are -4 and -7.
However, the power above x + 4 is even, meaning the graph will simply <em>touch</em> the x-axis at x = -4, but not pass through. The power above x + 7, though, is odd, which means the graph will <em>cross</em> the x-axis.
Thus, the answer is x = -7.
Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
The answer is c hope it’s right
Answer: 7
Step-by-step explanation:
Given: Triangle UVW map to triangle XYZ where Triangle UVWhas side Lengths 3,4,2, and triangle XYZ has lengths 14,28,21.
We know that the scale factor between two similar figures is the the ratio of the corresponding side of image to the original figure.
Let k be the scale factor.
Then,
![k=\frac{21}{3}=\frac{14}{2}=\frac{28}{4}=7\\\\\Rightarrow\ k=7](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B21%7D%7B3%7D%3D%5Cfrac%7B14%7D%7B2%7D%3D%5Cfrac%7B28%7D%7B4%7D%3D7%5C%5C%5C%5C%5CRightarrow%5C%20k%3D7)
Hence, the scale factor = 7
