Could you please help me with this problem?
NeTakaya

First Question:

Number of trapezoids - 6

Perimeter - 72

3 + 3 + 3 + 6 = <u>15</u>

3 + 3 + 3 + 3 + 6 + 6 = <u>24</u>

3 + 3 + 6 + 3 + 3 + 6 + 3 + 6 = <u>33</u>

15 + 24 + 33 = <u>72</u>

Second Question:

Number of cubes - 6

Surface area - 24 (probably 480 since it said <em>area</em>)

first cube - 6 ones

second cube - 8 ones

Third cube - 10 ones

you could do 6 + 8 + 10 = 24 or add up all the ones (1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1) and you will still get 24

(It said <em>area</em>, and area means to multiply so maybe its 6 x 8 x 10 = 480 and not 6 + 8 + 10)

Anyways have a good day/night :) I might be wrong, but I hope I helped at least a little

Answer:

D. d = 5

Step-by-step explanation:

d = d² - d¹

= 5 - 0

If a baseball player get a hit in 31% of his at-bats, what is the probability that he will
solong [7]

Given:

A baseball player get a hit in 31% of his at-bats.

To find:

The probability that he will  get a hit 5 at-bats in a row.

Solution:

Since, a baseball player get a hit in 31% of his at-bats, therefore

Probability that he get a hit = \dfrac{31}{100}

                                           = 0.31

Now, the probability that he will  get a hit 5 at-bats in a row is

P=0.31\times 0.31\times 0.31\times 0.31\times 0.31

P=(0.31)^5

P=0.0028629151&#10;

Therefore, the required probability is (0.31)^5 and it can be written as 0.0028629151 .
