The College Board reported that in a recent year, the mean mathematics SAT score was 514 and the standard deviation was 118. A sample of 65 scores was chosen.

a) The probability that the sample mean score is less than 500 can be found by using the mean and standard deviation of the SAT scores population. The formula to calculate this probability can be found in 3.

c) The 80th percentile of the sample scores is also not mentioned in the search results. To find the 80th percentile, a probability distribution of the sample mean scores must be created and then solved for the desired percentile.

The length of the third side should be between 5 and 17.

A triangle is a three-sided polygon because it has three edges and three vertices. The most important attribute of a triangle is the sum of its internal angles to 180 degrees.

Given John is measuring a piece of glass to fit in a triangular frame,

the two sides of the frame are 6 cm and 11 cm,

let the third side be x,

Any two sides of a triangle can be added together to have a length larger than the third side. Similar to this, any two triangle sides have length differences between them that are smaller than the length of the third side.

i.e. 11 - 6 < x < 11 + 6

5 < x < 17

Hence the third side should vary from 5 cm to 17 cm.

Answer:

2.  y = 3x + 6

3.  y = 2x

4.  y = 5x + 60

Step-by-step explanation:

Slope-intercept form: y = mx + b

2.

Pick 2 points (0,6) (1,9)

The y increase by 3, and the x increase by 1, so the slope is

m = 3

the y-intercept is located at (0,6)

Our equation is y = 3x + 6

3.

Pick 2 points (0,0) (1,2)

The y increase by 2, and the x increase by 1, so the slope is

m = 2

the y-intercept is located at (0,0)

Our equation is y = 2x

4.

Pick 2 points (0,60) (2,70)

The y increase by 10, and the x increase by 2, so the slope is

m = 10/2 = 5

the y-intercept is located at (0,60)

The distance traveled by Jasmine and Chelsea is given by the equations of speed and J = 20.4 km and C = 39 km , where T is the time taken and T = 0.6 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of Jasmine be represented as S₁ = 34 km/h

Let the speed of Chelsea be represented as S₂ = 65 km/h

Now , the distance traveled by Jasmine = J

And , the distance traveled by Chelsea = C

The measure of J = measure of C

So , the distances are the same

Let the time taken by both Jasmine and Chelsea be T

Now , Speed = Distance / Time

Substituting the values in the equation , we get

Distance D = 34T

And , distance D = 65T

Now , the total distance D = 59.4 km

So , 34T + 65T = 59.4

On simplifying the equation , we get

99T = 59.4

T = 0.6 hours

Hence ,

The distance traveled by Jasmine and Chelsea are 20.4 km and 39 km respectively

The mean of the repair cost is 2.1 dollars and the variance of the repair cost is 0.

Let's call the number of items with no defects x. Then, we have:

x + y1 + y2 = 10

And we know that:

[tex]y1 = 10 * 0.10 = 1[/tex]

y2 =[tex]10 * 0.07 = 0.7[/tex]

x = 10 - y1 - y2 = 10 - 1 - 0.7 = 8.3

So, the expected number of items with one defect is E(y1) = 1 and the expected number of items with more than one defect is E(y2) = 0.7.

The expected repair cost is [tex]E(cost) = E(y1) * 3 * E(y2) = 1 * 3 * 0.7 = 2.1.[/tex]

The variance of the number of items with one defect is Var(y1) = E(y1^2) - [tex](E(y1))^2 = 1^2 - 1^2 = 0[/tex] and the variance of the number of items with more than one defect is [tex]Var(y2) = E(y2^2) - (E(y2))^2 = 0.7^2 - 0.7^2 = 0.[/tex]

The solution to the given system of linear equations is (x, y) = (-1, 1).

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of equations is given in the question, as follows:

-6y + 2 = 4x

y - 2 = x

Here's how to solve this system of equations using the elimination method:

Multiply the first equation by 2:

-12y + 4 = 8x

Add the two equations:

-12y + 4 + y - 2 = 8x + x

-11y + 2 = 9x

Solve for x:

x = (2 - 11y)/9

Substitute the value of x back into one of the original equations to find y:

-6y + 2 = 4x

-6y + 2 = 4((2 - 11y)/9)

-6y + 2 = (8 - 44y)/9

-54y + 18 = 8 - 44y

26y = 26

y = 1

Use the value of y to find x:

x = (2 - 11y)/9

x = (2 - 11 * 1)/9

x = (2 - 11)/9

x = -9/9

x = -1

Thus, the solution is (x, y) = (-1, 1).

The selling price of the bags of almonds that yields a profit of 45% is $420.5

An equation is an expression that shows the relationship between two or more numbers and variables using mathematical operations. An equation can be linear, quadratic, cubic and so on, depending on the degree of the variable.

The formula for profit is given by:

Profit = [(selling price - cost price) / cost price] * 100%

At the nut farm, the cost price of a bag of almonds is R290. It is sold with a profit of 45%. Hence, substituting:

45% = [(selling price - 290)/290] * 100%

0.45 = (selling price - 290)/290

selling price - 290 = 130.5

The value of the car can be, to the nearest cent, after 6 years is, 108454 cents

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

New car is purchased for 21100 dollars

The value of the car depreciates at 10.5% per year

The value of the car  after 6 years = ?

After 1 year,

Value  = 21100 -  10.5% of 21100

           = 21100 - (10.5x21100)/100

           = 21100 - 0.105x21100

           = 21100(1 - 0.105)

After 2 year,

Value  = 21100(1 - 0.105) -  10.5% of 21100(1 - 0.105)

           = 21100(1 - 0.105) - 0.105x21100(1 - 0.105)

           = 21100(1 - 0.105)(1 - 0.105)

           = 21100(1 - 0.105)²

Similarly, After n years,

Value = 21100(1 - 0.105)ⁿ

So, After 6 years,

Value = 21100(1 - 0.105)⁶

          = 21100x0.895⁶

          = 21100x0.514

          = $10845.4

It is known that,

1 dollar = 100 cents,

So, value in cents after 6 years,

⇒ 10845.4x100

⇒  108454

Hence, the value after 6 year is 108454 cents

Answer:

The unit rate of pages per hour is 39 pages and the unit rate of hour per pages is 1/39 hours

Step-by-step explanation:

We can solve this problem using proportion.

From the question; Leo reads 13 pages in 1/3 hours.

The first part of the question is to find the unit rate for pages per hour.

To find this;

Let x = the number of pages read in 1 hour

13 pages = 1/3 hours

   x         = 1 hour

Cross-multiply

1/3 ×  x = 13 × 1

= 13

Multiply both-side of the equation by 3

 ×  3   =   13× 3

x = 39 pages

Therefore, the  number of pages read in 1 hour is 39 which implies the unit rate for pages per hour is 39

For the second part of the question, we are to find the unit rate for hours per page, that is; how many hours can he use to read a page.

Let x = the number of hour use to read a page

13 pages   =   1/3 hour

1 pages    =  x

Cross-multiply

13x = 1/3

To get the value of x, we will divide both-side of the equation by  1/13

13x ×    =   ×  

x   =   hour

Therefore, the number of hour taken to read 1 page is    , which implies the unit rate of hours per page is

The correct answer is it will stretch far 59.3 lakh miles .

Given that,

If a billion 10-dollar bills were placed side by side, the total value would be $1.

To find :What amount of dollars would you use? How far would the trail stretch?

A dollar bill is 2.61 inches wide.

The dimensions of a billion dollar bill are 2.61 x 1,000,000,000 inches.

Divide this by 12 to convert to feet: 2.61 x 1,000,000,000 / 12.

Divide that by 5280 to convert it to miles: 2.61 x 1,000,000,000 x 12 /5280.

If the average service rate is 6 customers per hour, and assuming the negative exponential distribution is used to describe the randomness of the service time distribution. The probability that the service time will be less than or equal to 6 minutes is 0.549 [B]

The average service rate of 6 customers per hour corresponds to a mean service time of 1/6 = 0.1 hour = 6 minutes. To find the probability that the service time will be less than or equal to 6 minutes, we need to find the cumulative distribution function (CDF) of the exponential distribution evaluated at 6 minutes. The CDF of the exponential distribution is given by:

F(x) = 1 - exp(-λx)

Oldfield mice come in a variety of colors; fawn-colored (medium or dark) individuals are typically found in inland regions, whilst lighter or white individuals are found in coastal regions. As a result, Santa Rosa Island should have more colored mice and the beach should have more light-hued mice.
