Remember
aln(c)=ln(c^a)
and
ln(a)-ln(b)=ln(a/b)

so

3ln3-ln9=
ln(3^3)-ln9=
ln27-ln9=
ln(27/9)=
ln3

Which statements about experimental probability are true? Check all that apply.

makvit [3.9K]

The last one is always so. "People will elect Trump by a narrow margin based on a sample of 10000 people with a % error of 2%" is a typical statement.

A probability experiment will always count the number of times an event occurs. That's the whole point of an experimental probability. How many people respond favorably to a new Cancer Treatment is a typical question asked by someone conducting an experiment in probability.

C is kind of iffy. Perhaps it is too expensive, or it takes place over too long a period. Ideally repeat trials should take place whenever possible. Bone Marrow Transplants are very expensive because of the strict isolation conditions. You're likely only to get one study done this, especially initially. To check to see if Cancer is a generational thing would be an example of a study that takes too long to repeat many times.

B is simply not true. They are not the same. What theoretical model would you use to mimic a survey? You actually have to go do the survey.

A is wrong. It is the other way around.

Answer C is a maybe but check it. D and E are both true.

Solve the system of equations and choose the correct ordered pair.

frez [133]

What I would do:

5x + 10y = 35

Divide everything by 5.

x + 2y = 7

x = 7 - 2y

Now plug "x" into either one of the equations.

2(7-2y) + 5y = 15

14 - 4y + 5y = 15

14 + y = 15

y = 1

Now, solve for x by plugging in y into either one of the equations.

2x + 5y = 15

2x + 5 =15

2x = 10

x = 5

So x is 5 and y is 1.

Check by plugging in the values into the other equation.

5x + 10y = 35

5(5) + 10(1) = 35

25 + 10 = 35

35 = 35

The values are correct so, the answer for this problem is B (5, 1).

4 1/2 divided by 2 3/8

Yuki888 [10]

First you make them mixed numbers:
9/2 ÷ 19/8
Then you flip the second fraction around
9/2 ÷ 8/19
Then you change ÷ to ×
9/2 × 8/19
And then multiply across!
72/38 = 1 34/38 = 1 17/19 (the final answer)
Hope this helps!
