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 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 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).

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)

Our equation is y = 5x + 60

a) A histogram representing coat color for the initial colony your graph is given below.

b) Due to the fact that beach mice, which often have light coast colors, outnumber Oldfield colonizers by a factor of several, making dark coat colors less prevalent as time passes.

a) It's critical to understand the geographic distribution of Oldfield mice prior to the histogram presentation. Santa Rosa Island is classified into two primary geographic locations: inland and coastal, although having various different geographical settings.

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.

b) Oldfield colonists have predominantly dark coat colors, according to the image. The second histogram shows the coast color of the population following 6000 years of Oldfield and beach mouse hybridization. This is due to the fact that beach mice, which often have light coast colors, outnumber Oldfield colonizers by a factor of several, making dark coat colors less prevalent as time passes.

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

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)

where,

λ = 1/mean = 1/0.1 = 10. Plugging in x = 6, we get:

F(6) = 1 - exp(-10 * 6) = 1 - exp(-60) ≈ 0.549

It is based on the likelihood of something occurring. The reasoning behind probability is the foundation of theoretical probability. The probability of getting one or two in first and second toss is [tex]\frac{1}{9}[/tex].

Probability is a number that represents the likelihood or chance that an event will occur. Probabilities can be expressed as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

The probability of getting one or two in first toss will be:-

[tex]\frac{1}{6} + \frac{1}{6} = \frac{1+1}{6} = \frac{2}{6} = \frac{1}{3}[/tex] ( as the probability of getting one in first toss is [tex]\frac{1}{6}[/tex] and getting two is also [tex]\frac{1}{6}[/tex]).

Similarly the probability of getting one or two in second toss will be:-

[tex]\frac{1}{6} +\frac{1}{6} = \frac{1+1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]

The total probability of getting one or two in first and second toss will be:-

The number of pivot columns in a matrix is equal to the rank of the matrix. Therefore, if A has only the trivial solution, it has rank 0, and so it has 0 pivot columns. To calculate the rank of a matrix, we can use the following formula: rank(A) = min(m, n) - dim(null A), where m and n are the number of rows and columns of A, respectively, and dim(null A) is the dimension of the null space of A.
