The answer is 12. This is because 4+8=12, and 12 divided by 2 is 6. Therefore a=6. 10+8=18, and 18/3 equals 6. Therefore, b=6. 6+6 is 12.

2a-8=4
Add eight to both sides of equal sign.
2a=12
Divide both sides by 2
A =6

3b-8=10
Add eight to both sides of the equal sign.
3b=18
Divide by 3 on both sides
B= 6

A + b=
6 +6= 12

Your answer is 12.

Step-by-step explanation:

It is given that a company claims the average cereal in boxes of breakfast cereal = 15 ounces

And we know that the mean amount is nothing but the average amount of any data.

Mean is synonym word of average .

The statistical mean is the mean or average that is used to find the central tendency of the data in any question.

kaheart [24]

Answer:

The center/ mean will almost be equal, and the variability of simulation B will be higher than the variability of simulation A.

Step-by-step explanation:

Solution

Normally, a distribution sample is mostly affected by sample size.

As a rule, sampling error decreases by half by increasing the  sample size four times.

In this case, B sample is 2 times higher the A sample size.

Now, the Mean sampling error is affected and is not higher for A.

But it's sample is huge for this, Thus, they are almost equal

Variability of simulation decreases with increase in number of trials. A has less variability.

With increase number of trials, variability of simulation decreases, so A has less variability.

If the foreign exchange rate between the japanese yen and the euro is 190:1, how many yen will equal 10 euros?
alexgriva [62]

Alright, lets get started.

The foreign exchange rate between the japanese yen and the euro is 190:1 given.

It means 1 euro = 190 yen

We are asked to find how many yen will be equal to 10 euros.

Means we need to multiply given euros with 190 because 1 euro = 190 yen

Hence 10 euros = 190 * 10 yen

10 euros = 1900 yen : Answer

Hope it will help :)
