Isaiah and Wanda both went bowling last weekend, but not together. Isaiah went during open bowling time, paying $16 for shoe ren

DIA [1.3K]

Answer:

1 hour

Step-by-step explanation:

Let the number of hours bowled by Isaiah and Wanda be X

Isaiah spent 16 dollars on shoe rental and 2X on bowling

Wanda spent 13 dollars on shoe rental and 5X on bowling

Since they spent the same amount, set up an equation

16+2X=13+5X

subtract 2X on either side, then subtract 13 from either side we get

3X=3

divide both sides by 3

X=1

12.what is the probability that a boy and a girl chosen randsomly will be seniors?

zhenek [66]

$\frac{\textbf{1}}{\textbf{20}}$

Step-by-step explanation:

Probability= $\frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$

Probability for a randomly chosen girl to be senior= $\frac{\text{number of senior girls}}{\text{total number of girls}}$

Probability for a randomly chosen girl to be senior= $\frac{7}{8+11+9+7}=\frac{7}{35}=\frac{1}{5}$

Probability for a randomly chosen boy to be senior= $\frac{\text{number of senior boys}}{\text{total number of boys}}$

Probability for a randomly chosen girl to be senior= $\frac{9}{10+7+10+9}=\frac{9}{36}=\frac{1}{4}$

For two independent events,

Probability for both event 1 and event 2 to take place= $\text{probability of event 1} \times \text{probability of event 2}$

Since choosing boys and girls is independent,

Probability for both boy an girl chosen to be senior= $\text{probability for boy to be senior}\times\text{probability for girl to be senior}$

Probability for both boy and girl chosen to be senior= $\frac{1}{5} \times \frac{1}{4} = \frac{1}{20}$

So,required probability is $\frac{1}{20}$

Equivalent fractions for 9/11, 15/17, and 2/3 using the least common denominator.

TiliK225 [7]

The (small) challenge here is to determine what the LCD is. Since 11, 17 and 3 are all prime, we find the LCD by multiplying them together: 561.

Then 9/11= 459/561; 15/17 = 495/561; and 2/3 = 375/561.
