The solution is Option 2.

The probability of selecting a ball that has an odd number and is divisible by 5 is 2/15

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the probability of selecting a ball that has an odd number and is divisible by 5 be P

Now , the equation will be

The total number of balls in the bag = 15 balls

The numbered balls in the bag A = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 }

The numbers of the balls in the bag that are divisible by 5 B = { 5 , 10 , 15 }

The odd numbers from the set B = { 5 , 15 }

So , the probability of selecting a ball that has an odd number and is divisible by 5 P = odd numbers from the set B / total number of balls in the bag

Substituting the values in the equation , we get

The probability of selecting a ball that has an odd number and is divisible by 5 P = 2/15

Therefore , the value of P is 2/15

Hence , the probability is 2/15

Answer: x= 3.5

Step-by-step explanation: 4(3x) = 12x

4(-8)= -32

12x - 32 = 10

+32 = +32

12x = 42

x = 3.5

Answer:

x=3.5

Step-by-step explanation:

Start off by using distributive property ---> 12x-32=10, then add 32 on both sides---> 12x=42, then divide 12 on both sides--->x=3.5 and that is the final answer!

Answer:

The birch tree needs 12 years

Step-by-step explanation:

Proportional Relationship

Two variables t and d are proportional if they have the relationship described by the equation:

d = kt

Where k is the constant of proportionality.

From the graph on the question, we recognize the proportionality of the age of a birch tree and its diameter because the line passes through the origin (0,0). To find the equation, we need to recognize a clear point on the graph. We select the point (2,7). Substituting in the equation:

7 = 2k

Thus:

[tex]k=\frac{7}{2}[/tex]

The equation is:

[tex]\displaystyle d=\frac{7}{2}t[/tex]

For the birch to have a diameter of d=42 inches, the time needed can be calculated by solving the equation:

[tex]\displaystyle 42=\frac{7}{2}t[/tex]

[tex]\displaystyle t=42*\frac{2}{7}[/tex]

t = 12 years

The birch tree needs 12 years

Answer:

Step-by-step explanation:

Answer:

Let 's' be the length of a side of the polygon.

Then,

perimeter = 15s

or, 120 = 15s

or, s = 8ft.

The area of regular polygon having 'n' number of sides with each of length 's' is given by:

A = [tex][{\frac{s}{2tan(\frac{180}{n}) }} (n)(s)]^{2}[/tex]

According to question,

s=8ft, n = 15

Therefore, Area = [tex][\frac{8}{2tan(\frac{180}{15}) }(15)(8)] = [\frac{480}{2tan(12)}] = (240cot12)[/tex] ≈1129.11sq. ft

Step-by-step explanation:

Let us represent

The cost of a

Packet of tea = x

Packet of coffee = y

Five packets of tea and seven of coffee cost $39.40

5x + 7y = 39.40.....Equation 1

Three packets of tea and five of coffee cost $26.20.

3x + 5y = 26.20.......Equation 2

Combining both Equations

5x + 7y = 39.40.....Equation 1

3x + 5y = 26.20.......Equation 2

Multiply Equation 1 by 5 and Equation 2 by 7 to eliminate y

25x + 35y = 197.... Equation 3

21x + 35y = 183.4......Equation 4

Subtract Equation 4 from 3

3x = 13.6

x = 13.6/3

x = $4.53

Therefore, the cost of a packet of tea is $4.53

Answer:

D is your answer

Step-by-step explanation:

(2y-7) (y+6) that is my answer and it matches with D promise 100%

The possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

The correct answer is (D).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the possible dimensions of the pool, we need to factor the trinomial 2y² + 5y - 42.

We can start by looking for two numbers that multiply to -84 (the product of the first and last coefficients of the trinomial) and add up to 5 (the middle coefficient of the trinomial).

Those numbers are 12 and -7, because 12 x -7 = -84 and 12 + (-7) = 5.

Using these numbers, we can rewrite the trinomial as:

2y² + 12y - 7y - 42

Now we can factor by grouping:

(2y² + 12y) - (7y + 42)

2y(y + 6) - 7(y + 6)

(2y - 7)(y + 6)

So the possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

Therefore,

The possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

The correct answer is (D) 2y - 7 and y + 6.

Answer:

Step-by-step explanation:

Since your slope is 5/2, it means the function will go up five units and to the right two units. Since we know this, we can see that a needs to be 4 spaces to the left of the second point, thus making it -6, and b needs to be 5 above the second point, thus making it -4

Answer: 19 people per sqaure mile

Step-by-step explanation:

Given : Population in 2000 = 103,970,000

The population increased by 13.4% in 2010.

Population in 2010 = 103,970,000 + 13.4% of (103,970,000)

= 103,970,000+ (0.134)(103,970,000)

= 103,970,000(1+0.134)

=103,970,000(1.134)

=117,901,980

In 2000,

Population density= [tex]\dfrac{\text{Population}}{\text{Area}}[/tex]

[tex]=\dfrac{103970000}{761700}\approx 136\text{ people per square mile}[/tex]

In 2010

Population density = [tex]\dfrac{\text{Population}}{\text{Area}}[/tex]

[tex]=\dfrac{117901980}{761700}\approx155\text{ people per square mile}[/tex]

Difference = 155-136 = 19 people per sqaure mile

Hence, the increase in population density in 2010 = 19 people per sqaure mile
