Answer:

Monday: 4 hours = $36

Tuesday: 6 hours = $54

Wednesday: 5 hours = $45

His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:

36 = k × 4 (k = $9)
54 = k × 6 (k = $9)
45 = k × 5 (k = $9)

Hope this helps!

Hello,

Perimeter is a function of the number of hexagons.

$p_1=6\\
p_2=2*6-1\\
p_3=3*6-2\\
p_4=4*6-3\\\\

\boxed{p_n=n*6-(n-1)}\ =6n-n+1=\boxed{5n+1}\\

Two marbles are drawn without replacement from a box with 3 white, 2 green, 2 red, and 1 blue marble, find the probability that

Sergio039 [100]

The total number of marbles is $3+2+2+1=8$ .

If we draw a red marble, the chance of that occurring is $\frac{2}{8}=\frac{1}{4}=0.25$ .

Now the total number of marbles left is 7. If we then draw a green marble, the chance of that occurring is $\frac{2}{7}\approx 0.29$ .

So the chance of drawing a red, then green, marble is $\frac{1}{4}*\frac{2}{7}=\frac{2}{28}=\frac{1}{14}\approx 0.07$ .
