In the above question, we need to from 3 probability questions and then give solutions for them

Example 1 : A coin is tossed three times. What is the probability of getting at least one head?

Solution : A coin is tossed 3 times then

Sample space = [HHH, HHT, HTH, THH, TTH, THT, HTT, TTT]

Total number of ways = 2 × 2 × 2 = 8

Favorable Cases = 7

P (A) = 7/8

OR

Probability (of getting at least one head) = 1 – P (no head)⇒ 1 – (1/8) = 7/8

Example 2 : Three red and four black balls are contained in a bag. Randomly, one ball gets taken out of the bag. Determine the probability that the drawn ball is

(i) black

(ii) not black

Solution :

Total number of balls in the bag are = 3 + 4 = 7 balls

Number of favorable outcomes or number of black balls in the bag = 4

(i) Probability getting black balls = [tex]\frac{number of favorable outcomes}{number of total outcomes}[/tex]

P(black ball) = [tex]\frac{4}{7}[/tex]

(ii)  Probability getting no black balls = 1 - P(black ball)

= 1 - [tex]\frac{4}{7}[/tex]

= [tex]\frac{3}{7}[/tex]

Example 3 : Given two dice, what is the likelihood of receiving the number 7?

Mathematical probability - There are 36 ways in all, or 6 times 6. Favorable scenarios are (1, 6) (6, 1) (2, 5) (5, 2) (3, 4) (4, 3), etc., in six different ways. P (A) = 6/36 = 1/6

Answer:

Inverse Function = 4x -8

Step-by-step explanation:

replace x with y and replace x with y

solve for y (meaning isolate y)

y=(1/4x) +2

x= (1/4y) +2

x-2 = 1/4y

multiply by 4 on each side to remove 1/4 from the right side

4(x-2) = y

y= 4(x-2)

y= 4x -8

Inverse Function = 4x -8

y=-1/3-4

Step-by-step explanation:

point slope form!

y-y=m(x-x)

with the point (-6,-2) and the slope (-1/3) replace the 2nd variables of each variable and replace m with the slope

y-(-2)=-1/3(x-(-6))

then solve that normally

y-(-2)=-1/3(x-(-6))

y+2=-1/3x -2

The unit price per ounce at Price-Club is $0.29 per ounce and the unit price per ounce at Shop Mart is $0.21 per ounce.

The unit price can be determined by dividing the total cost by the total ounce that is purchased.

Division is the process of putting a number into  equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. The result of the division process is known as the quotient. Other mathematical operations include addition, subtraction and multiplication.

Unit price = total cost / total ounce sold

Unit price of Price-Club = $3.44 / 12 = $0.29 per ounce

In order to determine the unit price of Shop Mart, pounds have to be converted to ounces

1 pound = 16 ounces

To convert 2 1/2 pounds to ounces, multiply 2 1/2 by 16. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

16 x 2 1/2

16 x 5/2 = 40 ounces

Unit price of Shop Mart = $8.35 ÷ 40 = $0.21 per ounce

Answer: The value of the house when it was purchased was 120,000

Step-by-step explanation:

1) Set up the equation. Let x be the house.

x-x*35%= 78,000

First, the house decreases 35% of the cost of the original house. It now costs 78,000.

2) Solve the equation.

x-x*0.35 = 78,000

x-0.35x=78,000

0.65x = 78,000

x= 120,000

Answer:

  4.  (d)

  5.  (b)

Step-by-step explanation:

You want to apply the secant and chord rules to the circles given in the diagram.

The secant rule is "the product of distances from the point of intersection of secants to the two points of intersection of the secant with the circle is the same for both secants." A tangent can be considered to be a secant that has both points of intersection with the circle in the same place.

The chord rule is similar to the secant rule: "The product of distances from the point of intersection of the chords to their intersection with the circle is the same for both chords."

The diagram shows a tangent of length 12, so the product of distances to the two points of intersection with the circle is 12(12).

The secant has length 8 to the near point of intersection, and (x+8) to the far point of intersection. That product is the same as for the tangent:

  8(x +8) = 12(12) . . . . . . matches choice D

One chord has lengths of 14 and x, so the product of those is 14x.

The other chord has lengths of 12 and 21, so the product of those is 12(21).

The product is the same for both chords, meaning ...

  14x = 12(21) . . . . . . matches choice B

__

Additional comment

We have purposely tried to write the rules in "parallel" fashion, because we find them easier to remember that way. Considering a tangent to be a secant with the points of intersection with the circle merged means the same rule can be used for all three cases:

The farmer will purchase five bags of kind A and six bags of type B.

Per bag, Type A includes 9 pounds of oats and 3 pounds of maize.

Per bag, Type B includes 2 pounds of oats and 10 pounds of maize.

The farmer is looking for a blend that comprises at least 57 pounds of oats and 75 pounds of maize.

Allow the farmer to mix type A feed = x pounds.

and feed type B = y pounds

(9x + 2y) pounds of oats when blended

Corn amount when combined: (3x + 10y) pounds

Oats equation: 9x + 2y = 57 ———— (1)

Corn equation: 3x + 10y = 75 ————- (2)

Subtract equation (2) from equation (2) by multiplying it by three (1)

3(3x + 10y) - (9x + 2y) = 75×3 - 57

9x + 30y - 9x - 2y = 225 - 57

28y = 168

y = 6 bags

derived from the equation (1)

9x + 2×6 = 57

9x + 12 = 57

9x = 57 - 12

9x = 45

x = 5 bags

Because the business has 15 bags of each sort, each bag costs $4.

As a result, the cost of 5 bags of type A and 6 bags of type B is = (54) + (64)

= 20 + 24

= $44

The farmer intends to buy five bags of kind A and six bags of type B.

The equation of the scatter plot is y = 5/3x + 2 and the tree will be 18.7 feet in ten years

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The information that completes the question is added as an attachment

From the scatter plot, we have the following points

(x, y) = (0, 2) and (6, 12)

The equation of the line is calculated as

y = (y2 - y1)/(x2 - x1) * (x - x1) + y1

Substitute the known values in the above equation

So, we have

y = (12 - 2)/(6 - 0) * (x - 0) + 2

So, we have

y = 5/3x + 2

In ten years, the value of x is

x = 10

The equation is given as

(ax + 2)(5x + b) = 10x^2 + bx + c

Open the brackets

So, we have

5ax^2 + 10x + abx + 2b = 10x^2 + bx + c

By comparing the above equation.

We have the following set of equations

5a = 10

10 + ab = b

2b = c

By solving the equations, we have

a = 2

Substitute a = 2 in 10 + ab = b

10 + 2b = b

So, we have

b = -10

Substitute b = -10 in 2b = c

2(-10) = c

Triangle LMN is an obtuse angle then, the angle at vertex L is acute, the angle at vertex N is acute.

The triangle LMN is an obtuse angle at the vertex M. So by the definition of obtuse angle triangle LMN is an obtuse angle.

As ∠M is an obtuse angle

So 90° < m∠M < 180°

By the property of a triangle,

m∠L + m∠M + m∠N = 180°

m∠M = 180° - (m∠L + m∠N)

90° < 180° - (m∠L + m∠N) < 180°

90° - 180° < -(m∠L + m∠N) < 0

-90° < -(m∠L + m∠N) < 0

90° >(m∠L + m∠N) > 0

90° > m∠L  and 90° > m∠N

Therefore both angles L and N are acute angles.

The intersection's two opposing corners are 91.40 feet apart.

Since the given data are:

Width of the Hillsboro Street = 73 feet

Width of Manchester Avenue = 55 feet

When Hillsboro Street and Manchester Avenue cross, calculate the distance between the intersection's two opposing corners,

Because the junction of Hillsboro Street and Manchester Avenue created a right-angled triangle:

Using Pythagoras's Theorem,

H² = B² + P²

H² = (55)² + (73)²

H² = 3025 + 5329

H² = 8354

H = √8354

H = 91.40
