mr. and mrs. smith plan to roof the cabin on 2 consecutive days. asusming that the chance of rain is independent of the day, what is the progbability it will rain both days

Answers

Answer 1

By using the concept of probability, it can be calculated that

Probability that it will rain on both the days = 0.04

What is probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

Probability of rain on the first day = 0.2

Probability of rain on the second day = 0.2

Assuming that the chance of rain is independent of the day

Probability that it will rain on both the days = 0.2 [tex]\times[/tex] 0.2 = 0.04

would it be unusual for a random sample of 500 adult americans to result in 210 or more who believe marriage is obsolete?

Answers

Yes, it would be unusual for a  500 adult Americans to result in 210 or more who believe marriage is obsolete. The probability value is 0.39 for adult Americans.  

We know very well that probability is defined as the ratio of number of favorable outcomes to the total number of outcomes.

We have given that 39% american adults women believes that marriage is now obsolete.

So,39% of 500 adult American women is =[(39/100)×500]

                                                                     =39×5=195

So,probability of adult women who believes marriage is obsolete is =(195/500)=0.39

Now, we need to check that whether 210 women believes marriage is obsolete or not.

So, number of favorable outcome is 210 and total number of outcomes=500.

Therefore, probability of adult women who believes marriage is obsolete is=(210/500)=0.42

Now,we can see that 195 women probability is lower than 210 women probability. It means that more number of women considered marriage is obsolete.

Hence, yes it is unusual and the  probability value of adult Americans is 0.39

Answers

We want to finish each statement by analyzing the graph provided.

The function's y-intercept is y =2.

y = 3x+2 is the equation.

The line connects (0, 2) and (2, 6).

What is meant by a function?

The earliest known attempt to the concept of function may be traced back to the works of Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Functions were initially the idealization of how a variable quantity depended on another quantity. The position of a planet, for example, is a function of time.

So, first, we need to find the y-intercept. We know that the y-intercept is the y-value at which the function intersects the y-axis, and we can see from the graph that the y-intercept is y = 2.

Then we'd like to see the line's equation.

Remember that y = ax + b is a generic line.

Where a denotes the slope and b the y-intercept, we may deduce:

y = ax + 2

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a=(y₂-y₁)/(x₂-x₁)

Given that the line passes through (0, 2) and (-2/3, 0), the slope is as follows:

a=(-2/3)/(-2)

a=1/3

The equation of the line is:

y =3x+2

And using that equation, we can show that the line does indeed pass through the points (0, 2) and (2, 6)

Answer:

y = 2x - 9

Step-by-step explanation:

The slope is the change in y over the change in x.  From the 2 points, the y's are 7 and 5.  The x's are 8 and 7.

[tex]\frac{7-5}{8-7}[/tex] = [tex]\frac{2}{1}[/tex] = 2

2 is the slope.

Now we need to find the y intercept (b).  Use one of the points on the line.  It does not matter which one.  I am going to use (8,7)

slope (m) = 2

x = 8

y = 7

y=mx + b

7 = 2(8) + b  Plug in what we know and solve for b

7 = 16 + b  Subtract 16 from both sides

-9 = b

The y intercept (b) is -9

y = mx + b

y = 2x -9

We have been given a number, y, is equal to twice the sum of a smaller number and 3

So, we get an equation,

y = 2(x + 3)

y = 2x + 6                        

2x - y = -6

The larger number is also equal to 5 more than 3 times the smaller number.

So, we get an equation,

y = 5 + 3x                        

3x - y = -5

Therefore, the equations represent the situation:

2x - y = -6

3x - y = -5

Suppose that a monopolistically competitive firm must build a production facility in order to produce a product. The fixed cost of this facility is FC = $24. Also, the firm has constant marginal cost, MC = $3. Demand for the product that the firm produces is given by P = 27- 3Q.
Fill in the entire table below. All of the numbers you fill in will be integers (no decimals), some have been added.
Quantity of Output Price Total Cost Average Total Cost Total Revenue Profits
1 2 3 4 5 7.8 6 7 6.4 8 9 5.7 B. How many units of output will the firm produce if it maximizes its profit?
C. What price should this firm charge if it wants to maximize its profit?

Answers

The output firm will get maximum profits when the quantity is 4 units and the company will charge a price of $15 for maximum profit.

The fixed cost of this facility is FC = $24. Also, the firm has constant marginal cost, MC = $3

Demand for the product that the firm produces is given by P = 27- 3Q.

The total cost is calculated by adding fixed cost and variable cost.

TC = FC + VC

Average total cost = total cost / quantity

Quantity  price (37 - 3Q) fixed cost variable cost  total cost average cost

1                27 - 3(1) = 24      24            3 (1)                 27             27

2               27 - 3(2) = 21      24            3(2) = 6           30            15

3                27 - 3(3) = 18      24            3(3) = 9           33            11

4               27 - 3(4) = 15       24           3(4) = 12          36             9

5               27 - 3(5) = 12       24           3(5) = 15          39            7.8

Upon analysing the table we can say that

B) the number of output units is 4

C) Maximum profit is when price is $15

Therefore, the maximum profit is when the output units is 4 and the company will charge a price of $15 for maximum profit.

6 3/ 4 divide by 4 1/2

Answers

The value of the equation A = ( 6 3/4 ) / ( 4 1/2 ) is 3/2 or 1 1/2

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be A = 6 3/4

A = 27/4

Let the second number be B = 4 1/2

B = 9/2

Now , the equation is C = A/B

The value of C = A / B

Substituting the values of A and B in the equation , we get

Value of C = ( 6 3/4 ) /  ( 4 1/2 )

Value of C = ( 27/4 ) / ( 9/2 )

Value of C = ( 27 / 9 ) / 2

Value of C = 3 / 2

Therefore , the value of C is 3/2 or 1 1/2

Hence , The value of the equation A = ( 6 3/4 ) / ( 4 1/2 ) is 3/2 or 1 1/2

nine tiles are numbered 1, 2, 3, . . . , 9, respectively. each of three players randomly selects and keeps three of the tiles, and sums those three values. the probability that all three players obtain an odd sum is m/n, where m and n are relatively prime positive integers. find m n.

Answers

The value of m and n from the obtained probability is equal to 3 and 14 respectively.

As given in the question,

Nine tiles numbered 1, 2, .....9

Number of odd numbered tiles are 1,3,5,7,9 = 5

Number of even numbered tiles are 2,4,6,8 = 4

Number of players =3

Possibility to choose 3 tiles by first player out of 9 tiles = ⁹C₃

                                                                                            = 84 ways

Possibility to choose 3 tiles by second player out of 6 tiles = ⁶C₃

                                                                                                 =20 ways

Possibility to choose 3 tiles by third player out of 3 tiles = ³C₃

                                                                                             = 1 way

Total number of ways = 84× 20 ×1

                                     = 1680

To have a sum of 3 tiles is odd number at least one tile should be odd.

Chances of first player all the 3 tiles are 0dd out of 5 = ⁵C₃

Next two players must 2 even tiles and 1 odd tile.= ²C₁

One player can be selected in ³C₁ way

Remaining 4 even tiles distributed equally = (4!)(2!)/ (2!)² ( 2!)

Number of favourable outcomes =  ⁵C₃ × ²C₁ ׳C₁  × (4!)(2!)/ (2!)² ( 2!)

                                                       = 10 × 2 × 3 × 6

                                                       = 360

Probability (m/n) =  360 /1680

                            = 3/14

m = 3 and n = 14.

Therefore, from the probability that all three players obtain an odd sum is m/n , the value m = 3 and n = 14.
