Answers:

A) 3/10
B) 7/10

=================================================

Explanation:

15 people said they plan to work out of 50 total.

15/50 = 3/10 of his sample plans to work, which is the experimental probability of picking someone who plans to work.

---------------

50-15 = 35 people do not plan to work

35/50 = 7/10 is the experimental probability of picking someone who doesn't plan on working.

Or you could compute it like this 1 - 3/10 = 7/10 because there are only two options. Either the person plans to work or they don't.

Answer:

JM = 10

Step-by-step explanation:

Because MN║JL,

$\frac{MK}{JM} = \frac{KN}{NL}$

$\frac{5}{2x + 4} = \frac{6}{12}$ = $\frac{1}{2}$

2(5) = 1(2x + 4)

10 = 2x + 4

2x = 6

x = 3

JM = 2x + 4 = 2(3) + 4 = 6 + 4 = 10

What is 3.8 repeating as a fraction in simplest form

Olin [163]

$\bf 3.8888888\overline{8}\\\\
-------------------------------\\\\
x=3.8888888\overline{8}\qquad thus\qquad 
\begin{array}{llcll}
10x&=&38.888888\overline{8}\\
&&\downarrow \\
&&35+3.8888888\overline{8}\\
&&\downarrow \\
&&35+x
\end{array}
\\\\\\
10x=35+x\implies 9x=35\implies x=\cfrac{35}{9}$

the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
