If X = 2 centimeters, Y = 6 centimeters, and Z = 6 centimeters, what is the area of the object?

Sedbober [7]

In order to answer the question, it's absolutely essential to have
enough of a description of the object to know which of its parts
'X', 'Y', and 'Z' are, and what other parts it may have.

An ideal way to accomplish this would have been for you to include the
picture that accompanies the question, wherever you copied it from.

Write repeating decimal as a fraction 0.2045454545

Mkey [24]

First, we need to move the decimal point directly in front of the repeating part. To do this, we need to move it two places to the right, which we can do by multiplying by 100.

100 × 0.2045454545 = 20.45454545

Now we need to subtract our original number.

$\ 20.454545...\\\underline{-0.204545...}\\20.25$

Now we put that over 99 (that's one less than our 100 from earlier)

$\frac{20.25}{99}$

Our fraction is shaping up, but we shouldn't have a decimal in there. Let's multiply the top and bottom by 100 to get rid of it.

$\frac{2025}{9900}$

We're going to have to do some simplifying. (the top and bottom are both clearly divisible by 5 and then some)

$\frac{2025}{9900}=\frac{405}{1980}=\frac{81}{396}=\frac{27}{132}=\boxed{\frac{9}{44}}$ <em> done!</em>

The average wind speeds for one year at 44 climatic data centers around the United States are as follows:

fgiga [73]

The stem and leaf diagram is shown below

There are a total of 48 data

Question a:
The frequency in the stem for 9 to 9.9 is 13 data

Question b:
The location of the first quartile is given by $\frac{n+1}{4}$ , where 'n' is the number of data

We have n = 48

Location of the first quartile is at $\frac{48+1}{4}= \frac{49}{4}= 12.25$ rounded down to 12

The value of the lower quartile is on the $12^{th}$ on the diagram which is 8.7
