I do not know because I am 8 years old sorry
Answer:
D. for the first one, A. for the second (not certain)
Step-by-step explanation:
1. 36/2 (two books every visit) = 18, multiplied by 3 because that's how many often he does to the library (every 3 weeks)
2. 13/2 = w/5 because for every 13 cups of water, there is two cups of cleaner, so for w (unknown amount of water) there would be 5 cups of concontrated cleaner.
Using the binomial distribution, we have that you would expected to draw a face card 8 times.
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For this problem, the parameters are given as follows:
- n = 35, as the experiment will be repeated 35 times.
- p = 0.2308, as of the 52 cards, there are 12 faces, hence 12/52 = 0.2308.
Then the expected value is found as follows:
E(X) = np = 35 x 0.2308 = 8
You would expected to draw a face card 8 times.

A quasi-experiment with one treatment and one control group that measures the dependent variable only nonequivalent control group posttest only design.
The quasi experiment design is defined as the attempt to produce the cause and effect relationship by using different types of criteria except randomization
The dependent variable is the variable that the value of this variable affected by the other variables
The treatment is defined as the any independent variable that affected by the experimenters.
Here the quasi-experiment with one treatment and one control group that measures the dependent variable only once.
Therefore, this is a nonequivalent control group posttest only design
