Answer:
I think it's the last one! In an experiment, one group is studied over a short period of time---
D.) x = 40
E.) x = 12
F.) x = 32
G.) x = 12.25
H.) x = 9
I.) x = -3
Hello.
In order to solve a proportion, you should cross-multiply:
Multiply 7 times 9 and 5 times x:
5x=63
Divide both sides by 5:
x=
Now let's solve the second proportion.
Multiply 8p times 6 and 12 times 15:
48p=180
Divide both sides by 48:
p=3.75
I hope it helps.
Have an outstanding day.
The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

What is Experimental Probability?</h3>
Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.
Here , Favorable Outcome = 19
Total outcomes = 20
Probability = Favorable Outcome/ Total Outcome
= 19 / 20
= 95%
Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

Answer:
Because a bracket is used, the solution includes 
The solution includes numbers from negative infinity to
Step-by-step explanation:
we know that
If the solution for an inequality is (–∞, 6.5]
then
The solution is all real numbers less than or equal to
so
Because a bracket is used, the solution includes
The solution includes numbers from negative infinity to
