Answer:

a) 0.0879 = 8.79% probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.

b) 0.3672 = 36.72% probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need for money to buy drugs.

Step-by-step explanation:

For each theft, there are only two possible outcomes. Either it was motivated by a need to buy drugs, or it wasnt. Thefts are independent, which means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

In a certain city district, the need for money to buy drugs is stated as the reason for 75% of all thefts.

This means that [tex]p = 0.75[/tex]

Next 5 theft cases

This means that [tex]n = 5[/tex]

(a) exactly 2 resulted from the need for money to buy drugs;

This is P(X = 2).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{5,2}.(0.75)^{2}.(0.25)^{3} = 0.0879[/tex]

0.0879 = 8.79% probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.

(b) at most 3 resulted from the need for money to buy drugs.

This is

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{5,0}.(0.75)^{0}.(0.25)^{5} = 0.0010[/tex]

[tex]P(X = 1) = C_{5,1}.(0.75)^{1}.(0.25)^{4} = 0.0146[/tex]

[tex]P(X = 2) = C_{5,2}.(0.75)^{2}.(0.25)^{3} = 0.0879[/tex]

[tex]P(X = 3) = C_{5,3}.(0.75)^{3}.(0.25)^{2} = 0.2637[/tex]

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0010 + 0.0146 + 0.0879 + 0.2637 = 0.3672[/tex]

0.3672 = 36.72% probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need for money to buy drugs.

Answer:

8.5

Step-by-step explanation:

Convert the percent to a decimal.

20% ÷ 100 = 0.2.

X = 17 ÷ 0.2.

X = 8.5

So 20% of 17 is 8.5.

Step-by-step explanation:

to make a graph, when you have the equations, as you do,  just make up a table of some x coordinates,  you get to choose which ever ones you want so pick some easy ones,   like - 2,-1 , 0, 1, 2  .. then put each of those numbers into your equations as the x ... one at a time, ofc,   and see what you get out for y.  then you have the y coordinate of your table  

when you have your table then you can plot each of the points,  if you use the Demos  web site graphing tool you can make the graph on your computer , or use a graph paper.

Answer: A

Step-by-step explanation:

Box A has a greater value than Box B. Expression of box A on being solved will result in a bigger value than that of box B.

Expression, in mathematics, is a combination of numbers, variables, functions, etc in a meaningful way.

Without multiplying, it is needed to compare both expressions.

As in the operation 'multiplication', numbers can interchange their position around the symbol '×', so, changing places of 4 and 8 in the numerator of the expression of box A,

Box A: [tex]\dfrac{8}{5} \times \dfrac{4}{9}[/tex].

The first fractions in both expressions are the same now in both boxes, so the expression having a bigger second expression will have the greater value.

To compare the second terms of both expressions, make the denominator equal:

Box A: [tex]\dfrac{8}{9} = \dfrac{8}{9} \times\dfrac{2}{2} = \dfrac{16}{18}[/tex]

Box B: [tex]\dfrac{1}{2} =\dfrac{1}{2} \times \dfrac{9}{9} = \dfrac{9}{18}[/tex]

Since, [tex]\dfrac{16}{18}\geq \dfrac{9}{18}[/tex] as [tex]16 \geq 9[/tex],

Therefore, the expression in Box A is greater than that of Box B.

Answer:

The perimeter can not be 26 inches

Step-by-step explanation:

Given

[tex]Side\ 1 =19[/tex]

[tex]Side\ 2 =16[/tex]

Required

Is a perimeter of 26 possible?

First, calculate the possible side 3

[tex]Side\ 3 = Perimeter - Side\ 1 - Side\ 2[/tex]

[tex]Side\ 3 = 26 - 16 - 19[/tex]

[tex]Side\ 3 = -9[/tex]

The side length can not be negative.

So, the perimeter can not 26 inches

Answer:

divide 9,255 divide 1/3 and you will get your answer hope this helps :)))

Step-by-step explanation:

In the town of Summit, 3,085 people have jobs. If there are 9,255 people in the town and 1/3 of them are employed.

To find the number of people in the town of Summit who have jobs, we can multiply the total population by the fraction representing the employed individuals.

Total population = 9,255 people

Fraction employed = 1/3

Number of people employed = Total population * Fraction employed

Number of people employed = 9,255 * (1/3)

To simplify the fraction (1/3), we can divide both the numerator and denominator by their greatest common divisor, which is 1 in this case.

Dividing 1 and 3 by 1, we get:

1/1 = 1

3/1 = 3

So, the simplified fraction is 1/3.

Continuing the calculation:

Number of people employed = 9,255 * (1/3)

Number of people employed = 9,255 / 3

Number of people employed = 3,085

Therefore, in the town of Summit, 3,085 people have jobs.

Answer:

28

Step-by-step explanation:

Here is the complete question used in answering this question :

Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?

We first have to determine the fraction of the boats that are red

1 - ([tex]\frac{3}{4}[/tex] + [tex]\frac{4}{7}[/tex])

1 - [tex]\frac{21 + 16}{28}[/tex]

1 - [tex]\frac{37}{28}[/tex]

1 - 1[tex]\frac{9}{28}[/tex]

= 9/28

so, 9/28 of the boats are red

let b represent the total number of boats

9/28 x b = 9

to find b, divide both sides of the equation by 28/9

b = 28

Step-by-step explanation:

[tex]x - 9 - 3 = y \\ y = x - 12[/tex]

The given equation solved for y as x-12.

The given equation is x-9=3+y.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

x-9=3+y

⇒y=x-9-3

⇒y=x-12

Therefore, the given equation solved for y as x-12.
