Jolly had 12 burgers from the start.

if his five friends ate 2, you'd multiply that and get 10, then you add how many Jolly ate, which is 12.

Answer:

12 burgers

Step-by-step explanation:

Let Jolly had x burgers. If he eats two burgers then remaining burgers = (x-2)

Now he divides these remaining burgers among his five friends. Then each friend gets 2 burgers.

So the equation will be

\frac{(x-2)}{5}=2

We further simplify this equation to get the value of x.

(x-2) = 2 × 5

(x-2) = 10

x = 10 + 2

x = 12

Therefore, there were 12 burgers.

On any given day, mail gets delivered by either Alice or Bob. If Alice delivers it, which happens with probability 1/4 , she doe
Troyanec [42]

Answer:

(a) The value of fₓ (9.5) is 0.125.

(b) The value of fₓ (10.5) is 0.50.

Step-by-step explanation:

Let <em>X</em> denote delivery time of the mail delivered by Alice and <em>Y</em> denote delivery time of the mail delivered by Bob.

It i provided that:

X\sim U(9, 11)\\Y\sim U(10, 12)

The probability that Alice delivers the mail is, <em>p</em> = 1/4.

The probability that Bob delivers the mail is, <em>q</em> = 3/4.

The probability density function of a Uniform distribution with parameters [<em>a</em>, <em>b</em>] is:

f(x)=\left \{ {{\frac{1}{b-a};\ a, b>0} \atop {0;\ otherwise}} \right.

The probability density function of the delivery time of Alice is:

f(X_{A})=\left \{ {{\frac{1}{b-a}=\frac{1}{2};\ [a, b]=[9, 11]} \atop {0;\ otherwise}} \right.

The probability density function of the delivery time of Bob is:

f(X_{B})=\left \{ {{\frac{1}{b-a}=\frac{1}{2};\ [a, b]=[10, 12]} \atop {0;\ otherwise}} \right.

(a)

Compute the value of fₓ (9.5) as follows:

For delivery time 9.5, only Alice can do the delivery because Bob delivers the mail in the time interval 10 to 12.

The value of fₓ (9.5) is:

f_{X}(9.5)=p.f(X_{A})+q.f(X_B})\\=(\frac{1}{4}\times \frac{1}{2})+(\frac{3}{4}\times0)\\=\frac{1}{8}\\=0.125

Thus, the value of fₓ (9.5) is 0.125.

(b)

Compute the value of fₓ (10.5) as follows:

For delivery time 10.5, both Alice and Bob can do the delivery because Alice's delivery time is in the interval 9 to 11 and that of Bob's is in the time interval 10 to 12.

The value of fₓ (10.5) is:

f_{X}(10.5)=p.f(X_{A})+q.f(X_B})\\=(\frac{1}{4}\times \frac{1}{2})+(\frac{3}{4}\times\frac{1}{2})\\=\frac{1}{8}+\frac{3}{8}\\=0.50

Thus, the value of fₓ (10.5) is 0.50.

A flower pot, in the shape of a cylinder,l has a circumference of 66 in. and a height of 30 in.
Vaselesa [24]
The amount of soil that the pot can hold is best approximated by calculating for the volume of the cylinder through the equation,
                                V = πr²h
We first calculate for the radius, r, given the circumference, C
                      C = 2πr;    r = C/2π = 66 in/2(π) = 10.5 in
Then, substituting the known values. 
                             V = π(10.5 in)²(30 in) 
                                 V = 10,390.81 in³
Thus, the volume of the soil is approximately 10,400. The answer is the third set.
