\frac{3b}{b + 2} + 12 = \frac{3b}{b + 2} + \frac{12(b + 2)}{1(b + 2)} = \frac{3b}{b + 2} + \frac{12b + 24}{b + 2} = \frac{15b + 24}{b + 2} = \frac{3(5b + 8)}{b + 2}

How to slove this problem?

So, since the polygons are similar, they will share a scale factor. 

The dilation is a reduction.

SF= preimage/image

SF=48/40

SF= 1.2

To find the value of x, multiply 20 by 1.2, so:

20(1.2)=24

Thus, x = 24

Now, to check if the sides are proportional (this will determine if the polygons are, in fact, similar.)

24/20=1.2
48/40=1.2

BTW, the missing side measure for the image is 40 since 48 is its corresponding side, and 48/1.2 (SF) is 40.

Hence, we have 48/40= 1.2

D

Step-by-step explanation:

D is correct because the sqrt of 91 is 9.5 and 9<9.5<10 makes absolute sense

C is not correct because the sqrt of 33 is 5.7 and 6<5.7<7 does not make sense

B is not correct because the sqrt of 13 is 3.6 and 4<3.6<5 does not make sense

A is not correct because the sqrt of 65 is 8.06 and 7<8.06<8 does not make sense

What z score in a normal distribution has 33% of all score above it? ap stats quiz 2.2a answers?
Sladkaya [172]

What z score in a normal distribution has 33% of all score above it?

Answer: A z score which has 33% of all scores above it, will have 67% of all scores  below it.

To find the required z score, we need to find the z value corresponding to probability 0.67.

Using the standard normal table, we have:

z(0.67)=0.44

Therefore, the z score = 0.44 has 33% of all score above it.
