On saturday, you bowl at mar vista bowl, where renting shoes costs $2 and each game bowled is $3.50. on sunday, you bowl at pinz
ExtremeBDS [4]

Given, at Mar Vista bowl the cost of renting shoes = $2.

The cost for each game bowled = $3.50

There are g games given. So the cost for g games bowled = $(3.50)(g) = $(3.50g)

The total amount soent at Mar Vista Bowl = $(2+3.50g)

At Pinz, the cost for shoe rental = $5.

The cost for each game bowled = $3.25.

So the cost for g game bowled = $(3.25)(g) = $(3.25g)

Total amount spent at Pinz = $(5+3.25g)

Given, the amount spent ateach of the places is same.

so we can write the equation as,

2+3.50g = 5+3.25g

We will move 3.25 to the left side by subtracting it from both sides. we will get,

2+3.50g-3.25g = 5+3.25g-3.25g

2+0.25g = 5

Now we will move 2 to the right side by subtracting 2 from both sides. We will get,

2+0.25g-2 = 5-2

0.25g = 3

Now to get g we will divide 0.25 to both sides. We will get,

\frac{0.25g}{0.25}= \frac{3}{0.25}

g =\frac{3}{0.25}

g = 12

So we have got the required answer.

The number of games bowled = 12.

Is the distance a baseball travels in the air after being hit a discrete random​ variable, a continuous random​ variable, or not
LuckyWell [14K]

Answer: a continuous random​ variable

Step-by-step explanation:

<u><em>Can you count the distance it traveled?</em></u> You can't, so it couldn't be discrete because you can count discrete variables.

<u><em>Can you measure the distance it traveled? </em></u>You sure can, that makes it a continuous random variable.

<u><em>Do you know the exact distance it's going to travel?</em></u><u> </u>You won't, therefore it's a random variable since you don't know the value beforehand.
