Answer:

The correct option is B) $10,873.22

Step-by-step explanation:

Consider the provided information.

Beaumont made some home improvements for $8,944 using a six-month deferred payment plan with an interest rate of 21.57%.

First calculate the 21.57% of $8944.

This can be written as:

$\frac{21.57}{100}\times 8944=1929.2208$

If no payments are made then he need to pay $8,944 plus 21.57% of $8,944.

Thus, the total amount he needs to pay is:

8944 + 1929.2208 = 10873.2208 ≈ 10873.22

Hence, the correct option is B) $10,873.22

The number x is reduced by 25% and then halved

Maksim231197 [3]

Since it says the number x , this means x represents a number , reduced by 25 means that this is most likely half of 25 so whats half of 25%?

well 5 * 5 = 25 , so here is your answer = 5

To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil

Answer:

The sample has not met the required specification.

Step-by-step explanation:

As the average of the sample suggests that the true average penetration of the sample could be greater than the 50 mils established, we formulate our hypothesis as follow

$H_0$ : The true average penetration is 50 mils

$H_a$ : The true average penetration is > 50 mils

Since we are trying to see if the true average is greater than 50, this is a right-tailed test.

If the level of confidence is α = 0.05 then the $z_\alpha$ score against we are comparing with, is 1.64 (this is because the area under the normal curve N(0;1) to the right of 1.64 is 0.05)

The z-score associated with this test is

$z=\frac{\bar x-\mu}{s/\sqrt{n}}$

where

$\bar x$ = mean of the sample

$\mu$ = average established by the specification

s = standard deviation of the sample

n = size of the sample

Computing this value of z we get z = 3.42

Since z > $z_\alpha$ we can conclude that the sample has not met the required specification.

3y = x - 12 Y= 1/3X -4 parallel, perpendicular or neither

aliina [53]

Answer:

PARALLEL

Step-by-step explanation:

The second equation, y = (1/3)x - 4, has already been solved for y. To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.

We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

Yousef borrowed last term for tuition, books, and student fees. This term he plans to borrow because he knows his classes will b

Len [333]

The estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000

<h3>Estimate the amount of money Yousef will borrow by first rounding to the hundred</h3>

The amount borrowed are given as:

Last term = 1690

This term = 2345

When the amounts are rounded to the nearest hundred, the amounts borrowed become:

Last term = 1700

This term = 2300

The total amount is then calculated as:

Total amount = Last term + This term

Substitute the known values in the above equation

Total amount = 1700 + 2300

Evaluate the sum

Total amount = 4000

Hence, the estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000
