Please help urgent <br> only smart people
kykrilka [37]

Answer:

I'll try to help a bit! (I'm also a bit new to this as well)

First, we know that inscribed angle is half of the central angle:( don't know the theorem name)

m<BFD=m<DOB*1/2

So, using substitution:

76=m

Okay, we also know that m<ODC and m<OBC are 90 degrees (Properties of Tangents, and since OD and OB are radii, and the angle formed with the radius and the tangent is 90 degrees).

So we also know that the sum of all angles in a quadrilateral is 360 degrees, thus:

360=180+152+m

So the measure of angle <BCD is 28 degrees.

Hope this helps!

P.S. Stay Safe!

kyle is paying for his new car in 60 equal payments. the total of the car loan is $27,495. to the nearest cent (hundredths) what
nadya68 [22]
I believe all you have to do here is divide. So you would take the amount of the total car loan, and divide it by 60 because that is the amount of payments that will be made. 

So 27,495/60 = 458.25.

They payments would be 458.25.

When determining the sample size n, if the value found for n is 79.2, we would choose to sample 79 observations.
V125BC [204]

Answer:

False.

See explanation below,

Step-by-step explanation:

This statement is FALSE

When we want to calculate a sample size we need to specify thre important things:

1) Confidence level

2) Margin of error desired

3) Parameter of interest

For this case let's assume that our parameter of interest is the population mean \mu and for this case we know that the margin of error is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}  (1)

And on this case we specify a value for the margin of error and we are interested in order to find the value of n, if we solve n from equation (1) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (2)

Let's assume that the calculation for some values gives to us a result of n = 79.2 For this case is not appropiate round the answer to the nearest integer since we can't satisfy the condition of margin of error desired, so it's always better round up the answer to the nearest integer on this case 80 in order to ensure that the margin of error would be the desired.
