WILL GIVE BRAINLIEST!!!!!!! A boy had 20 cents. He bought x pencils for 3 cents each. If y equals the number of pennies left, wr
s2008m [1.1K]

Answer:

\displaystyle \text{Function: }{y=20-3x,\\\text{Domain: }(-\infty, \infty)\text{ or }\mathbb{R}

Step-by-step explanation:

If the boy initially had 20 cents, then the total number of cents he will have left after purchasing x pencils is equal to the total cost of the pencils subtracted from 20. The total cost of x pencils, in cents, is equal to 3x, since each pencil is 3 cents.

Therefore, the total amount, in cents, that the boy has left, y, is equal to 20-3x:

\displaystyle \text{Equation: }\boxed{y=20-3x}

The domain of this function is (-\infty, \infty) or all real numbers \mathbb{R}.

Let X be a random variable that is equal to the number of times a 5 is rolled in three rolls of a fair 5-sided die with the inte
Svetradugi [14.3K]

Answer:

Step-by-step explanation:

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Firstly we will make PMF

For X=0, P=(4/5)^3=64/125

For X=1, P=C(3,1)*(1/5)*(4/5)^2=3*16/125=48/125

For X=2, P=C(3,2)*(1/5)^2*(4/5)=3*4/125=12/125

For X=3, P=C(3,3)*(1/5)^3=1/125

So,

E[X^2]=1*48/125+2^2*(12/125)+3^2/125=0.84

E[X]=48/125+12/125*2+1/125*3=0.6

So,

E[X]^2=0.36
