PSYCHO15rus [73]

Answer:

A normal distribution or z-test is used to construct a confidence interval.

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = $3120

Sample size, n = 40

Population standard deviation, σ = $677

The distribution of earnings of college is a normal distribution.

Conditions:

anyanavicka [17]
<span>A gardener has 27 pansies and 36 daises. He planted equal parts of each flowers.
Now we need to find the value of flowers did the gardener planted.

If you’re looking for the greatest number of flowers planted in a row.
We can have 27 pansies and 27 daises.

However, if we want to plant all flowers we can have:
3 rows of pansies with 9 flowers = (3 x 9) = 27
4 rows of daises with 9 flowers = (4 x 9) = 36</span>

Answer:

5.25

Step-by-step explanation:

If CD is perpendicular to AB, a right angle is formed by the perpendicular lines at the base of the triangle. If we know that AB is 3 we can divided that by two to use half the triangle and create a right trianle with a base of 1.5 (half of 3) a height of rad 3 now all we have to do is use P-Thags to find AC which is the hypotenuse. After doing 1.5 squared + rad 3 squared = ac squared you will get the answer of AC = 5.25
