Answer:

The expected number of nondefective lightbulbs is 980 out of a random sample of 1,000 bulbs.

mylen [45]

Answer:

The amount that has to be deposited today is $6205.63

Explanation:

The given parameters are;

The annual interest rate for the first 5 years = 4 percent

The annual interest rate for the next 4 years = 4.6 percent

The annual interest rate for the final 8 years = 5.3 percent

Let the amount deposited be X, we have;

X × (1 + 0.04)⁵ + X × (1 + 0.04)⁵×(1.046)⁴ + X × (1 + 0.04)⁵×(1.046)⁴ ×(1.053)⁸ = $30,250

X ((1.04)^5 + (1 + 0.04)^5×(1.046)^4 + (1 + 0.04)^5×(1.046)^4 ×(1.053)^8) = $30,250

X × 4.875 = $30,250

X = $30,250/$4.875 = $6205.63

The amount that has to be deposited today = $6205.63.

Vika [28.1K]

Answer:

A. 0.684

Explanation:

A seasonal index refers to an index that is used to compare the value for a particular period with the average value of all periods.

The purpose of using a seasonal index is to show the relationship between the two values, and the degree to which the two values are different.

The seasonal index can be calculated as the latest value for a period divided by the average of all periods.  Therefore, we have:

Seasonal index for July = Latest value for July / Average demand over all months = 130 / 190 =  0.684.

Therefore, he approximate seasonal index for​ July is 0.684.
