Answer:

Central limit theorem

Step-by-step explanation:

The central limit theorem in Statistics states that whenever sample sizes become large, and random samples are drawn, the mean of all sample means will follow a normal distribution irrespective of the original distribution to which it belongs to.

In those cases, especially in hypothesis testing for random samples, inferences about population parameters we apply normal calculations to non normal distributions.

Help please logarithms

DochEvi [55]

Answer:

Simplified: 40

Step-by-step explanation:

To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: $x^{a+b} =x^ax^b$ We can do this same thing to simplify this expression. Next, we can simplify each of these terms. $2^2$ simply becomes 4. In the other term, the $2^{log_2}$ simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40

$2^{2+log_210} \\\\2^2*2^{log_210} \\\\4*10\\\\40$

find the probability of picking two green marbles when 2 marbles are picked from the bag containing 11 green and 8 blue marbles

AlexFokin [52]

Answer:

11/19 chance

roughly 57% chance.

Step-by-step explanation:

If we add our marbles, we have a total of 19 marbles to pick from. 11 of those marbles are green. This means we have a 11/19 chance of picking two green marbles.

If you want to find the percentage then do this:

We know that we have a 11/19 chance. To find the percentage, we would need to turn the fraction into a decimal first.

11÷19≈0.579

To turn a decimal into a percentage, we would need to multiply the decimal by 10 (move the decimal two spaces to the right.)

That would give us 57.9%.

So, you have, approximately, a 57% chance of picking two green marbles.

Hope this helps!! <3

Distribute the -2.5 to 4X and -3
It should look like -2.5 x 4X and -2.5 x -3(the answer for -3 should be positive)
