Answer:

Look below:)

Step-by-step explanation:

Area of triangle formula: (bh)/2

Where b=base

And h=height

Lets substitute b as 6x^4 and h as x^2

(6x^4*x^2)=6x^8

6x^8/2=3x^8

The expression : (6x^4*x^2)/2

Name: Quartic

Answer:3x^8

A cash register contains 5 $10 bills and 3 $5 bills. you randomly pick 4 bills.

kobusy [5.1K]

a. The probability of picking exactly two $10 bills is $\frac{3}{7}$

b. The probability of picking at most one $5 bill is $\frac{1}{2}$

Explanation

Number of $10 bills $= 5$

and number of $5 bills $= 3$

Total number of bills= 5+3 = 8. You need to randomly pick 4 bills, so the total possible outcome $= ^8C^4$

a.

For getting exactly two $10 bills, you need to pick two $10 bills and two $5 bills. That means we will pick two $10 bill from 5 bills and two $5 bills from 3 bills.

So, the probability $=\frac{(^5C^2)*(^3C^2)}{^8C^4} =\frac{10*3}{70}=\frac{30}{70}=\frac{3}{7}$

b.

For getting at most one $5 bill, you need to pick either zero or one $5 bill.

If you pick zero $5 bill, that means there are four $10 bills

and if you pick one $5 bill, that means there are three $10 bills.

So, the probability $=\frac{(^3C^0*^5C^4)+(^3C^1*^5C^3)}{^8C^4}=\frac{(1*5)+(3*10)}{70}=\frac{5+30}{70}=\frac{35}{70}=\frac{1}{2}$

Corporate bonds from Hyren Airlines are selling at 106.133, bonds from Xyx Motors are selling at 97.701, and bonds from Ergar Ap

Oksana_A [137]

Given:
Hyren Airlines - 106.133
Xyx Motors - 97.701
Ergar Appliances - 101.294
Par Value - $1,000 a piece

Hyren Airlines: 1,000 * 106.133 = 106,133
Xyx Motors: 1,000 * 97.701 = 97,701
Ergar Appliances: 1,000 * 101.294 = 101,294
Total 305,128

305,128 / 100 = 3,051.28

George will spend $3,051.28 to purchase one bond from each corporation.

What is the probability of rolling a sum of 5 if two regular 6-sided number cubes are rolled?

creativ13 [48]

1/9 because 5 shows up 4 times out of 36 times so that would be 4/36 and you would simplify it to get 1/9
