Answer: If P(x<a) = 0.6, then the value of a will be 0.25.

In this type of problem, it is safe to assume the normal distribution unless you are told something different.

In this probability, we have to find the z-score for a that gives a probability of 0.6. You will need a normal distribution chart to do this problem. Just find the probability that is closest to 0.6 and use that z-score.

(HELP PLEASE I BEG)The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning

maks197457 [2]

Step-by-step explanation:

First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)

Increase% = Increase ÷ Original Number ×100

451÷2750×100=16.4%

The sum of the interior angle measures of a convex polygon is 1620° . how many sides does it have?the sum of the interior angle

lesya692 [45]

If you are given a convex polygon with $n$ sides and $S$ is the sum of the measures of the interior angles then $S = 180(n - 2)$ .

So, $1,620 = 180(n-2)$ .
$n-2=9$
$n=11$

The polygon has 11 sides.
