<u>Step-by-step explanation:</u>

1st hour: 350 people bought tickets --> 350 × $17.50 = $6,125

2nd hour: 350(1.2) people bought tickets --> 350(1.2) × 17.50 = $7350

On Friday night, Alex ate a large pizza for dinner and had LaTeX: \frac{3}{5}3 5 of the pizza left over when he was done. On Sat

ludmilkaskok [199]

Answer:

Alex ate $\frac{3}{10}$ of the large pizza on Saturday.

Step-by-step explanation:

Given:

Amount of Pizza which was left over on Friday = $\frac{3}{5}$

Amount of Pizza ate on Saturday = $\frac{1}{2}$ of the Amount of Pizza was left over on Friday

We need to find how much did Alex eat on Saturday.

Solution;

Since we know that Alex ate on Saturday $\frac{1}{2}$ of the Amount of Pizza which was left over on Friday.

So to find the amount he ate n Saturday we will Multiply $\frac{1}{2}$ with the Amount of Pizza which was left over on Friday.

framing in equation form we get;

Alex ate on Saturday = $\frac{1}{2}\times \frac{3}{5}= \frac{3}{10}$

Hence Alex ate $\frac{3}{10}$ of the large pizza on Saturday.

A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that a red gumball is drawn if there

fgiga [73]

Answer:

0.99

Step-by-step explanation:

Given,

Pink gumballs = 3,

Red gumballs = 4,

Green gumballs = 2,

So, total gumballs = 3 + 4 + 2 = 9,

Thus, total ways of selecting 5 gumball = $^9C_5$

$=\frac{9!}{5!4!}$

$=\frac{9\times 8\times 7\times 6}{24}$

$=9\times 2\times 7$

$=126$

Also, the total ways of selecting no red gumballs = $^4C_0\times ^5C_5$

= 1 × 1

= 1

So, the probability of no red gumballs in 5 drawn

$=\frac{1}{126}$

Hence, the probability that a red gumball is drawn if there are 5 drawings

= 1 - probability of no red gumballs

$=1-\frac{1}{126}$

$=\frac{125}{126}$

≈ 0.99
