Answer: 
Step-by-step explanation:
The pool of rats from which the researcher is drawing participants is composed of the following:
23 male albino rats
21 male spotted rats
35 female albino rats
11 female spotted rats
Total rats = 23+21+35+11 =90
After drawing first rat , total rats remained = 89

The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = 
2:3:1....added = 6
2/6(72) = 144/6 = 24
3/6(72) = 216/6 = 36
1/6(72) = 72/6 = 12
ratio is now 24:36:12
the shorter piece is 8 feet long
the longer piece is 19 feet long

Answer:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.
Answer:
Part A: Histogram :)
Part B: Described below! :)
Step-by-step explanation:
Part A:
A histogram is the best choice because it can show the numbers for multiple categories in a quick and easy manner :)
Part B:
The x axis will have the categories of quiz scores! The y axis will show how many students got that score.
We then put the categories from smallest to largest along the x axis. We will also put the numbers that go with the categories above the category!
Done! you have made your histogram!
Have an amazing day!!
