<u>Answer:</u>

The expected value of construction company is $30500.

<u>Solution:</u>

Given, A construction company is planning to bid on a building contract.  

The bid costs $1,500 and has an 80% chance of being accepted.  

If accepted, the company will receive $40,000 dollars.  

We have to find the expected value.

We know that,  

Expected value = probability \times amount gained by bidding – bid amount

Expected value = 80% x 40000 – 1500

Expected value = 0.8 x 40000 – 1500

Expected value = 32000 – 1500

Expected value = 30500

Hence, the expected value is $30500.

A computer software vendor claims that a new version of its operating system will crash fewer than 10 times per year on average.
Oksana_A [137]

Answer:

Step-by-step explanation:

The hypothesis is written as follows

For the null hypothesis,

µd ≤ 10

For the alternative hypothesis,

µ > 10

This is a right tailed test

Since no population standard deviation is given, the distribution is a student's t.

Since n = 97

Degrees of freedom, df = n - 1 = 97 - 1 = 96

t = (x - µ)/(s/√n)

Where

x = sample mean = 8.9

µ = population mean = 10

s = samples standard deviation = 3.6

t = (8.9 - 10)/(3.6/√97) = - 3

We would determine the p value using the t test calculator. It becomes

p = 0.00172

Since alpha, 0.01 > than the p value, 0.00172, then we would reject the null hypothesis. Therefore, At a 1% level of significance, there is enough evidence that the data do not support the vendor’s claim.

I<br> 8. Classify 8 as a perfect square, a perfect cube, both, or neither.
Murljashka [212]

Answer:

It's a perfect cube, but not a perfect square.

Step-by-step explanation:

2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

I hope this helped.
