Answer:

Step-by-step explanation:

Where to start?

It isn't 2 and it isn't 3. You tell it's not 2 because it is an odd number.

It isn't 3 because the digits (26411 = 2 + 6 + 4 + 1 + 1) add up to 14 which is not divisible by 3, so the whole number is not divisible by 3.

It is not divisible by 5 because numbers divisible by 5 end either in 0 (which would make it even and divisible by 2) or 5. This one doesn't end in 5.

The very first number you can try is 7. That works. 3773 is the result.

The next prime to try is 11. I have a feeling that will work as well. Let's try it. It works as well. It's the symmetry of 3773 that made me look at eleven. There is a very complicated rule having to do with the odd and even places subtracted that tells you whether a number is divisible by 11 or not.

343 is the resulting number. I think that is 7^3 which is correct. So here's your answer

7 * 7 *7 * 7 * 11 is the answer. It's worthwhile to know how to do this. Factoring large numbers is one of the cornerstones of mathematics. Computers love this kind of thing.

A salesperson is paid an 8.25% commission on sales when the invoice is

son4ous [18]

Answer:

The salesperson's commission for this month is $3,803

Step-by-step explanation:

Percentages

Let's call x to the sales volume, not including commission.

The salesperson is paid an 8.25% commission on sales, thus the total invoice is x + 8.25%x = x + 0.0825x = 1.0825x

We are given this total invoice, thus:

1.0825x = $49,900

Dividing by 1.0825:

x = $46,097

The salesperson's commission is

0.0825*$46,097=$3,803

The salesperson's commission for this month is $3,803

Michela says that the modes of the two data are the same so the median and mean must also be the same. what is michela’s error?

aev [14]

Answer: median and mean are the same

Step-by-step explanation:

The error committed by Michela is by saying

The median and mean are the same.

Because in statistics, we can't use mode to predict the median and the mean.

Someone please help me!!!!!

1. Answer (D). By the law of sines, we have $\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$ in any $\triangle ABC.$

2. Answer (C). The law of cosines, $c^2=a^2+b^2-2ab\cos C,$ accepts up to three sides and an angle as an input.

3. Answer (D). Although this triangle is right, we are not given enough information to uniquely determine its sides and angles - here, we need either one more side or one more angle.

4. Answer (D). Don't get tripped up by answer choice (C) - this is just a rearrangement of the statement of the law of cosines. In choice (D), the signs of $a^2$ and $2ab\cos C$ are reversed.

5. Answer (B). By the law of sines, we have $\frac{5}{\sin 40^\circ}=\frac{3}{\sin\theta}.$ Solving gives $\theta\approx \boxed{23^\circ},157^\circ.$ Note that this is the ambiguous (SSA) case of the law of sines, where the given measures could specify one triangle, two triangles, or none at all!

6. Answer (A). Since we know all three sides and none of the angles, starting with the law of sines will not help, so we begin with the law of cosines to find one angle; from there, we can use the law of sines to find the remaining angles.
