Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get
Rounding, we get x = 16.35 as our answer
Answer:
C. 254.34 in^2
Step-by-step explanation:
The formula for area of a circle is πr² (pi x radius x radius).
Here, only the diameter is shown.
To find the radius, divide the diameter by 2.
18 / 2 = 9
9 is the radius.
We use 3.14 as π (pi).
Now we have the final equation.
pi x radius x radius
3.14 x 9 x 9 = 254.34 in^2.
Therefore, the area of the circle is 254.34 in^2.
The answers are the one on the top right, bottom one(middle), and I think the one on the top left.
Answer:
B
Step-by-step explanation:
Answer: Dilation and stretch
Step-by-step explanation:
- Rigid transformations that are also called as isometry are the transformations which preserves the side lengths and the angle measures of a polygon. It does not affect the size of the shape. The shape doesn't shrink or get enlarger.
There are four rigid transformations: <em>reflections, rotations, translations and glide reflection.</em>
- Dilation and stretch are non rigid transformation because they change the size of the figure. They produces similar figures.
