How can you establish credit? A. use one credit card to pay for another B. pay bills using your parents' credit card C. pay bills on time using credit

Answer:

The correct option is B.

Step-by-step explanation:

The area of pyramid is the sum of area of rectangular base and 4 triangular sides. Two triangle have base 18 ft and height 14.1 ft. Other two have base 10 ft and height 16 ft.

The area of rectangle is

Length of the base is 18ft and width is 10ft.

The area of a triangle is

The area of triangle with base 18 ft and height 14.1 ft is

The area of triangle with base 10 ft and height 16 ft is

The total surface area of the rectangular pyramid is

The surface area of the rectangular pyramid is 593.8 ft². Therefore the correct option is B.

Answer:

it is B

Step-by-step explanation:

Answer: B

Step-by-step explanation:

First off, choices A and D can be elimination because you are not subtracting. In choice C, we have 10 divided by 5 as opposed to z divided by 5. The answer is B.

The 90% confidence interval will be "(0.674, 0.748)".

Given:

Sample no. of events,

• x = 293

Sample size,

• n = 412

Now,

The sample proportion will be:

→

The significance level will be:

Form the z-table,

The critical value,

Now,

The standard error will be:

=

=

and,

The margin of error,

→

Now,

The lower limit will be:

=

=

The upper limit will be:

=

=

hence,

The CI is "(0.6744, 0.748)". Thus the response above is right.

Answer:

CI = (0.674, 0.748)

Step-by-step explanation:

The confidence interval of a proportion is:

CI = p ± SE × CV,

where p is the proportion, SE is the standard error, and CV is the critical value (either a t-score or a z-score).

We already know the proportion:

p = 293/412

p = 0.711

But we need to find the standard error and the critical value.

The standard error is:

SE = √(p (1 − p) / n)

SE = √(0.711 × (1 − 0.711) / 412)

SE = 0.0223

To find the critical value, we must first find the alpha level and the degrees of freedom.

The alpha level for a 90% confidence interval is:

α = (1 − 0.90) / 2 = 0.05

The degrees of freedom is one less than the sample size:

df = 412 − 1 = 411

Since df > 30, we can approximate this with a normal distribution.

If we look up the alpha level in a z score table or with a calculator, we find the z-score is 1.645.  That's our critical value.  CV = 1.645.

Now we can find the confidence interval:

CI = 0.711 ± 0.0223 * 1.645

CI = 0.711 ± 0.0367

CI = (0.674, 0.748)

So we are 90% confident that the proportion of adults connected to the internet from home is between 0.674 and 0.748.
