we know that for every 3 boys there are 4 girls

therefore it is a division operation

Please help, And Please show work so i can better understand. I replaced the angle symbol with the word angle. "<" I know i l

Gnesinka [82]

angle 2 = 114°

supplementary angles sum to 180° thus

5y + 16 + 10y + 14 = 180

15y + 30 = 180

subtract 30 from both sides

15y = 180 - 30 = 150

divide both sides by 15

y = $\frac{150}{15}$ = 10

angle 1 = (5 × 10) + 16 = 50 + 16 = 66° and

angle 2 = (10 × 10) + 14 = 100 + 14 = 114°

A bag contains 4 white, 3 blue, and 6 red marbles. A marble is drawn from the bag, replaced, and another marble is drawn. Find t

PilotLPTM [1.2K]

First find the probability of each color being drawn.

We need to find the total number of marbles first.

4 + 3 + 6 = 13

So everything will be over 13.

Probability of a white marble being drawn --> $\frac{4}{13}$

Probability of a blue marble being drawn --> $\frac{3}{13}$

Probability of a red marble being drawn --> $\frac{6}{13}$

Now to find the probabilities of more than one being drawn, we can multiply.

Part a :

$\frac{6}{13}*\frac{6}{13}=\frac{36}{169}$

Part b :

$\frac{3}{13}*\frac{3}{13}=\frac{9}{169}$

Part c :

$\frac{6}{13}*\frac{3}{13}=\frac{18}{169}$

Part d :

$\frac{7}{13}*\frac{7}{13}=\frac{49}{169}$
