Answer:

C, A

Step-by-step explanation:

First question:

As you can see the shape we're working with here is a pyramid and we must first understand that the 4 sides of a pyramid are triangles and the base of the pyramid is a square.

As shown in the picture, the cut is going horizontally through the same place the base is, so therefore, the shape the cross section would make would be a square. (c)

Second question:

Same shape; different size.

We're still working with a pyramid here, just that the base is bigger.

We can see how that the cut is going vertically through the middle of the triangle, parallel to it's side, which I mentioned earlier is a triangle

Therefore, the shape of this cross section would be a triangle. (a)

Cos B =<br>tan B =<br>sin B =

Oduvanchick [21]

The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).

Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse

Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse

Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.

The acronym to remember this is SOHCAHTOA

SOH | CAH | TOA

SOH means sin(x) = opposite/hypotenuse

CAH means cos(x) = adjacent/hypotenuse

TOA means tan(x)= opposite/adjacent

cosB = length of adjacent side/length of hypotenuse = 7/25

tanB = length of opposite/length of adjacent = 24/7

sinB = length of opposite/length of hypotenuse = 24/25

The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of

katen-ka-za [31]

Answer: The explanation is correct.

Step-by-step explanation:

The interpretation of 95% confidence interval for population mean is that "A person can be 95% sure that the true population mean lies in it."

Given : The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of all freshmen.

Interpretation: The admissions director can be 95% sure that the true population mean IQ score of all freshmen lies in (107.8, 116.2).

i.e. There is a 95% probability (chance) that the interval from 107.8 to 116.2 contains μ.

Hence, the explanation is absolutely "correct" .

I see that your new product is available for 412.50 on the website. How much is it if I buy it in the store? The website is a 25

OverLord2011 [107]

Answer with explanation:

Price of Product on the Website = $ 412.50

It is given that, product is offered at a discount of 25% on the website.

Let actual price of product on the store = $ x

Writing the above statement in terms of equation

→Price at store - Discount= Price at Website

$x-\frac{25\times x}{100}=412.50\\\\ \frac{75 x}{100}=412.50\\\\x=\frac{41250}{75}\\\\x=550$

Price at store of that Product = $ 550
