Lelechka [254]

Answer:

(a) $P(X=10) = 0.2070$

(b) $P(X\geq 10) = 0.3798$

Step-by-step explanation:

Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).

Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.

(a)

Therefore, to answer question (a) we use the following equation presented in the attached image:

Where:

$N = 50\\m = 30\\n = 15\\X = 10$

Then:

$P (X = 10) = \frac{\frac{30!}{10!(30-10)!}\frac{20!}{5!(20-5)!}}{\frac{50!}{15!(50-15)!}}\\\\\\P(X=10) = 0.2070$

(b)

For part (b) we have:

$P(X\geq10) = 1-P(X$

$P(X\geq 10) = 1-0.6202 \\\\P(X\geq 10) = 0.3798$

Kerry has 5 metal and 3 wood

Ray Of Light [21]

Expression

(5+3)+(5x2)=p

Solution

(Step-by-Step)

In this expression we simply have to use basic PEMDAS (Parenthesis Equation Multiplication Division Addition Subtraction) Order.

We start by working out the parenthesis

5 + 3 and 5 x 2

First let's work out our metal and wood paperweights

5+3=8

Simple enough, we have 8 metal AND wood paperweights

Now we have to work out our glass paperweights.

We have twice as many glass as we do metal PW's meaning we need to multiply the 5 metal paperweights by 2

5x2=10

This simplifies and boils our equation down to

8+10

simply solve and add the two and you have your answer

which shows the conversion of 3.04 × 10-4 meters to centimeters? a. 0.000304 m ÷ 1000 cm/m = 0.304 cm b. 0.000304 m ÷ 10 cm/m =

OlgaM077 [116]

1 m = 100 cm

3.04*10^-4 m
3.04 * 10^-4 * 100 cm
3.04 * 10^-2 cm

So the answer c is correct
3.04 m / 1000 cm/m
0.00304 cm
