Answer:

Well. Depending on Sam's age, she could've been kissed many times. Not just boy her bf or bestie, anyone could kiss her throughout her life time. Your question is very vague and can have many answers. But I'll take a guess and say she was kissed more than 122 times.

Step-by-step explanation:

Answer:

The answer is "1.448 miles".

Step-by-step explanation:

X= The distance to both the nozzle clogged from of the starting point.

X $\sim$ Uniform(0,2) miles.

They are simulating the random number Y=0.724, and the Y has both a distribution uniform(0,1). Therefore 2Y is distributed evenly (0.2). And They model the clogging of its nozzle at 2Y=1.448 miles

A company is considering a new manufacturing process. It knows that the rate of savings (in dollars per year) from the process w

Ainat [17]

Answer:

i). $\$ 7500$

ii). $\$ 67500$

Step-by-step explanation:

Given in the question-

Saving rate is s(t)= 3000(t+2)

We know that savings in the 1st year can be calculated as

$\int_{0}^{1}3000(t+2).dt$

$3000\left [ \frac{t^{2}}{2}+2t \right ]_0^1$

$3000\left [ \frac{1}{2}+2 \right ]$

= $\$ 7500$

So savings in the first 5 years can be calculated as

$\int_{0}^{5}3000(t+2).dt$

$3000\left [ \frac{t^{2}}{2}+2t \right ]_0^5$

$3000\left [ \frac{25}{2}+5 \right ]$

= $\$ 67500$

Astronomers treat the number of stars X in a given volume of space as Poisson random variable. The density of stars in the Milky

cupoosta [38]

Answer:

Explained below.

Step-by-step explanation:

The random variable X is defined as the number of stars in a given volume of space.

$X\sim \text{Poisson}\ (\lambda=1)$

The probability mass function of X is:

$p_{X}(x)=\frac{e^{-\lambda}\lambda^{x}}{x!}$

Compute the probability of exactly two stars in 16 cubic light-years as follows:

$P(X=2)=\frac{e^{-1}\times 1^{2}}{2!}=\frac{e^{-1}}{2}=\frac{0.36788}{2}=0.18394\approx 0.184$

(8)

Compute the probability of three or more stars in 16 cubic light-years as follows:

$P(X\geq 3)=1-P(X$

(9)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in 4 cubic light years there will be, 4 × (1/16) = (1/4) stars.

(10)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in t cubic light years there will be, [t × (1/16)] stars.

What number can 13 and 7 go into?

Drupady [299]

You're looking for the number 13 and 7 can go into.

You can use the listing method.
13: 13, 26, 39... and so on, and so on.
7: 7, 14, 21, 28, 35, 42, 49.... and so on.

An easier way to do it is to simply multiply 13 by 7.

$13*7= 91$

13 and 7 can go into 91, evenly.

Hope this helped!
