To find how many students did like the book we must find how many students didn't like the book because that is what we have data for.
We can find an equivalent fraction to 9/25 by multiplying by 4/4
9/25x4/4=36/100
36 of the 100 students did not like the book so now you subtract 100-36=64

64 students liked the book

The diagram shows two nested triangles that share a vertex.Find a center and a scale factor for a dilation that would move the l

nasty-shy [4]

Transformation that changes the size of a shape is referred to as dilation.

The scale factor that moves the large triangle to the small one is 1/5
The center of dilation is: (-1,1)

The center of dilation

From the diagram (see attachment), the triangles share a common vertex at (-1,1)

This means that, the center of dilation is (-1,1)

The scale factor of dilation

To do this, we divide the side length of the small triangle with the corresponding side of the large triangle.

From the attached image:

$\mathbf{Base\ of\ small\ triangle = 1}$

$\mathbf{Base\ of\ large\ triangle = 5}$

So, the scale factor (k) from large to small is:

$\mathbf{k = \frac{Base\ of\ small\ triangle}{Base\ of\ large\ triangle} }$

$\mathbf{k = \frac{1}{5} }$

The value of the 7 in 27,459 is how many times the value of the 7 in 40,735?

alukav5142 [94]

Answer:

Step-by-step explanation:

The 7 in 27,459 is in the thousands place.

The 7 in 40,735 is in the hundreds place.

Any digit in the thousands place has 10 times the value of the same digit in the hundreds place. (The multiplier is 1000, instead of 100.)

_____

In the base-10 number system, each digit location has 10 times the value of the location to its right. The value is determined by the place the digit occupies in the number. That is why it is called a place-value number system.

Which of the following would be a correct interpretation of a 99% confidence interval such as 4.1 less than muless than5.6? Ch

Harrizon [31]

Answer: A. We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.

Step-by-step explanation:

The correct interpretation of a 99% confidence interval is that we are 99% confident that the true population mean falls in it.

Given 99% confidence interval : $4.1$
