It would be 5x * 1 = 5x

Because the Identity Property of Multiplication means ::
the result of multiplying any real number by 1 is the number itself. In other words, multiplying any number by 1 doesn’t change the number’s value.

Which critical value is appropriate for a 99% confidence level where nequals17, sigma is unknown, and the population appears

My name is Ann [436]

Answer:

t Subscript alpha divided by 2 = 2.921

Step-by-step explanation:

With sample sizes lower than 30, we use the t-test.

Otherwise, we use the z-test.

Here, n = 17

So we use the t-test.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 17 - 1 = 16

Now, we have to find a value of T, which is found looking at the t table, with 16 degrees of freedom(y-axis) and a confidence level of 0.99( $t_{1 - (\frac{1-0.99}{2}}) = 0.995$ ). So we have T = 2.921

So the correct answer is:

t Subscript alpha divided by 2 = 2.921

Answer:

Step-by-step explanation:

hello :

an equation for the line A is : y-14 = 3(x-2) or y = 3x +8

an equation for the line B is : y-23 = 3(x-5) or y =3x +8

same line

C. The system of equations has an infinite number of real solutions.

note : same slope means parallal or identical

The NPV is positive, therefore, this order can be placed.

<h3>How to calculate the NPV?</h3>

The calculation of probability of default will be:

= 1 / 200 = 0.005

We use NPV formula to find out whether the order should be filled or not

NPV = -Variable cost per unit +[(1-π)(price of equipment/1+percentage of return)]

= -$1.6 million +[(1-0.005)($1.725m/1.018)]

= -$1.6m + $1.6860

= 0.0860 million

As NPV is positive this order can be placed.
