Answer:

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers

Step-by-step explanation: The mean of a data set is equal to the sum

of the set of number divided by how many numbers are in the set.

The mean is often referred to as the <em>average</em>.

The median is the middle number in the data set

when the data set is written from least to greatest.

Jane made a poster that had a length: 1 2/3 of feet and a width: 5/6 of feet. What is the perimeter of her poster?

slamgirl [31]

Answer:

P = 6 2/3 ft

Step-by-step explanation:

The formula for the perimeter of a rectangle of length L and width W is

P = 2(L + W).

Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)

= 2(15/6 + 5/6) = 2(20/6)

= 40/6 = 20/3

P = 6 2/3 ft

If a=22.3 and B=47°18’ find c (picture provided)

igor_vitrenko [27]

Answer:

d. 32.9

Step-by-step explanation:

To find c, we'll use the Law of Sines that says:

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

And we'll isolate a to get:

$c = \frac{sin(C) * a}{sin(A)}$

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:

A = 180 - 90 - 47.3 = 42.7

(converted 47°18' to 47.3)

Then we will plug-in the information we already have

$c = \frac{sin(90) * 22.3}{sin(42.7)} = 32.88$

So, let's round it to 32.9 to match the answer number D.

Answer:

$84.58

You would do 9.95 times 8.5 which gives you 84.575 which in money case you round to two decimal places you keep the 5 but 7 you round to 8 because "5 or more you add one more"
