Answer:
x = 0, 9
Step-by-step explanation:
To find our roots, set the binomial factors equal to zero:
x = 0
x - 9 = 0
x = 9
Answer:
Step-by-step explanation:
Given: Number of cards a box contains = 10 (numbered 1 through 10).
A random card is picked at first instance and is denoted X and then another card is picked from remaining cards and is denoted as Y
Here E(X) = (1+2+3+4+5+6+7+8+9+10)/10 = 5.5
E(Y)=P(X=1) *E(Y|X=1) +P(X=2) *E(Y|X=2) +. .+P(X=10)*E(Y|X=10)
= (1/10) *(2+3+4+ .+10)/9+(1/10)*(1+3+4+..+10)/9+....+(1/10)*(1+2+3+4+5...+9)/9
= (1/10) *(9/9) *(1+2+3+4+5+6+7+8+9+10) = 5.5
Hence, E(X-Y) = E(X) - E(Y) = 0.000
The total cost to join the website for one year is $34.00
Step-by-step explanation:
Onetime membership fee = $10
Per month newsletter charges = $2.00
One year = 12 months
Newsletter charges for 1 year = ![2.00*12=\$24](https://tex.z-dn.net/?f=2.00%2A12%3D%5C%2424)
Total cost = One time fee + newsletter charges for 1 year
![Total\ cost=10+24.00=\$34.00](https://tex.z-dn.net/?f=Total%5C%20cost%3D10%2B24.00%3D%5C%2434.00)

Answer:
16
Step-by-step explanation:
The sum of the 12 numbers is 12 * 24 = 288 and the sum of the 24 numbers is 24 * 12 = 288 so the sum of the 36 numbers is 288 + 288 = 576 which means the average is 576 / 36 = 16.
