Answer:

a = 12

Step-by-step explanation:

as C^2 = A^2 + B^2

by Pythagoras theorem

so

A^2 = C^2 - B^2

= 13^2 - 5^2

= 169- 25

144

as 12^2 is equal to 144

hence side a is equal to 12

Answer:

\(h^2 = p^2 + b^2 \\ {13}^{2} = {p }^{2} + {5}^{2} \\ 169 = {p }^{2} + 25 \\ 169 - 25 = {p}^{2} \\ 144 = {p}^{2} \\ \sqrt{144} = p \\ 12 = p \\ p = 12\)

The value of the first number. is 310.

A linear equatiοn is an algebraic equatiοn in which each term is either a cοnstant οr the prοduct οf a cοnstant and a variable raised tο the first pοwer. It represents a straight line οn a graph and has the fοrm y = mx + b, where m is the slοpe and b is the y-intercept.

Let's call the three numbers x, y, and z.

Frοm the prοblem, we knοw:

x + y + z = 665 (equatiοn 1)

x = 3z + 10 (equatiοn 2)

x = 2y - 200 (equatiοn 3)

We can use equatiοns 2 and 3 tο eliminate x and sοlve fοr y and z.

Substituting equatiοn 2 intο equatiοn 3, we get:

3z + 10 = 2y - 200

2y = 3z + 210

y = (3/2)z + 105

Nοw we can substitute this expressiοn fοr y intο equatiοn 1 and simplify:

x + y + z = 665

x + [(3/2)z + 105] + z = 665

x + (5/2)z = 560

Next, we can substitute equatiοn 2 intο this expressiοn tο eliminate x:

(3z + 10) + (5/2)z = 560

(11/2)z = 550

z = 100

Nοw we can substitute this value οf z intο equatiοn 2 tο find x:

x = 3z + 10 = 3(100) + 10 = 310

Therefοre, the first number is 310.

The probability that a randomly selected driver who had an accident is in the age group 16-20 is 0.34 or 34%.

Probability is a fundamental concept in mathematics and statistics that is used to measure the likelihood of an event occurring. In this scenario, Joey is interested in calculating the probability that a driver who had an accident is in a particular age group.

We are given the following information:

Probability of accident for drivers in the age group 16-20 = 0.08

Probability of accident for drivers in the age group 21-65 = 0.02

Probability of accident for drivers in the age group 66-99 = 0.01

We are also given the proportion of drivers in each age group:

Proportion of drivers in age group 16-20 = 0.10

Proportion of drivers in age group 21-65 = 0.65

Proportion of drivers in age group 66-99 = 0.25

Let A denote the event that a randomly selected driver had an accident, and let B denote the event that the driver is in a particular age group. Then, Bayes' Theorem states:

P(B|A) = P(A|B)P(B) / P(A)

where P(B|A) is the conditional probability of the driver being in age group B given that they had an accident, P(A|B) is the probability of an accident given that the driver is in age group B, P(B) is the prior probability of the driver being in age group B, and P(A) is the probability of observing an accident.

Using the information given in the problem, we can calculate the probability of an accident occurring:

P(A) = P(A|16-20)P(16-20) + P(A|21-65)P(21-65) + P(A|66-99)P(66-99)

= 0.08 * 0.10 + 0.02 * 0.65 + 0.01 * 0.25

= 0.0235

Similarly, we can calculate the other probabilities:

P(A|16-20) = 0.08

P(A|21-65) = 0.02

P(A|66-99) = 0.01

P(16-20) = 0.10

P(21-65) = 0.65

P(66-99) = 0.25

Substituting these values into Bayes' Theorem, we get:

P(16-20|A) = P(A|16-20)P(16-20) / P(A)

= 0.08 * 0.10 / 0.0235

= 0.34

Answer:

The dimensions that will maximize the enclosed area of the pen is 250 ft by 250 ft

Step-by-step explanation:

we have the perimeter as 1000

So the sum of the lengths will be

1000/2 = 500

The dimensions that will maximize these pens will be such that they will have equal values

Mathematically, that will be 500/2 = 250 by 250

From the question, we can deduce the following:

Length = 5.6 meters

Width = 7.3 meters

Height = 4.5 meters

Where:

1 ft = 0.3048 m

1 cubic foot = 7.48 gallons

Let's find the amount of gallons of water in the tank if the tank is filled to 1 foot below the top of the tank.

Let's first sketch the tank.

We have:

Now, let's find the volume of the tank(total amount of water it can carry).

Apply the formula:

Thus, we have:

Now, to find the amount of water presently in the tank since it is filled 1 ft below the top of the tank, we have:

Therefore, the volume of the water in the tank is 171.5 cubic meters.

Now, let'c convert from cubic meters to gallons.

Where:

1 foot = 0.3048 m

Thus, we have:

Now, to convert from cubic feet to gallons, where:

1 cubci foot = 7.48 gallon

We have:

Therefore, there are 45273.86 gallons of water filled in the tank.

The probability that an antigen test comes back positive is approximately 0.05225, or about 5.225%.

We have,

To find the probability that an antigen test comes back positive, we need to consider both the true positive rate (probability of a positive test given that the person is infected) and the false positive rate.

Now,

Prevalence of coronavirus in California: 3 out of 1000

False positive rate of the antigen test: 0.05 (5 out of 100)

Let's calculate the probability of a positive test result.

The true positive rate can be calculated as 1 minus the false negative rate (probability of a negative test given that the person is infected):

True positive rate = 1 - 0.2 = 0.8 (or 80 out of 100)

The probability of a positive test result can be calculated using Bayes' theorem:

P(Positive test) = P(Positive test | Infected) x P(Infected) + P(Positive test | Not Infected) x P(Not Infected)

P(Positive test) = (0.8 x 3/1000) + (0.05 x 997/1000)

P(Positive test) = 0.0024 + 0.04985

P(Positive test) = 0.05225

Therefore,

The probability that an antigen test comes back positive is approximately 0.05225, or about 5.225%.

Answer:

  y = -x +3

Step-by-step explanation:

You want the slope-intercept equation of the line with the same intercept as -3y = -9 +3x, and the same slope as -2x -2y = -8.

The slope-intercept form of the equation of a line is ...

  y = mx +b . . . . . where m is the slope, and b is the y-intercept

For the given equations, we can put them in this form to find the desired parameters.

  -3y = -9 +3x

  y = -x +3 . . . . . . . . . . divide both sides by -3

We observe that the y-intercept is +3, which we will need for our answer.

The slope-intercept form of the second equation is ...

  -2x -2y = -8

  x + y = 4 . . . . . . . . . . divide by -2

  y = -x +4 . . . . . . . . . . subtract x

We observe that the slope (coefficient of x) is -1, which we will need for our answer.

We want the equation of the line with slope -1 and y-intercept 3. It is ...

  y = -x +3 . . . . . . . . . . same as the equation of the first line

The slope-intercept equation (green) is plotted using dots, so that you can see it is coincident with the line described by the first equation (red). Parallel lines have the same slope, so our desired line must be parallel to the blue line. (It is.)

The length KL is 8 units

The value of x is undefined

The length KL is 12 units

From the question, we have the following parameters that can be used in our computation:

The rhombus

Also, we have

DK = 8

A rhombus is a quadrilateral with all sides equal.

So, we have

KL = 8

Here, we have

SKAL = 2x - 8

There is no point S on the rhombus

This means that

x = undefined

Here, we have

DM = 5y + 2 and DK = 3y + 6

A rhombus is a quadrilateral with all sides equal.

So, we have

5y + 2 = 3y + 6

Evaluate

2y = 4

Divide

y = 2

So, we have

KL = 5 * 2 + 2

KL = 12

Answer:

Step-by-step explanation:

A non-current liability is a debt or obligation that is not due within the next 12 months or the current operating cycle, whichever is longer. Therefore, option A "Long-term" best describes a non-current liability.

Option B "Short-term" describes current liabilities, which are obligations that are due within the next 12 months or the current operating cycle.

Option C "Has dramatic fluctuations" does not necessarily describe a non-current liability. Liabilities can have fluctuations in their balances regardless of whether they are current or non-current.

Option D "Funds day-to-day operations" describes current liabilities or working capital, which are used to finance a company's day-to-day operations.

Answer:

A

Step-by-step explanation:

A non-current liability is a type of liability that is not due for payment within the next 12 months. Therefore, the expression that best describes a non-current liability is A. Long-term.

Option B, Short-term, describes current liabilities, which are due for payment within the next 12 months.

Option C, Has dramatic fluctuations, does not describe a specific type of liability.

Option D, Funds day-to-day operations, describes working capital, which is the amount of money a company has available to fund its day-to-day operations and is not a type of liability.

Therefore, the correct answer is A. Long-term.
