Find the measures of the interior angles of the triangle.

Answers

The value of interior angle is 60.

What is triangle?

A triangle is a simple polygon with 3 sides and 3 interior angles. It is one of the basic shapes in geometry in which the 3 vertices are joined with each other and it is denoted by the symbol.

What is interior angle?

In a triangle, there are three interior angles at each vertex. The sum of those interior angles is always 180°. The bisectors of these angles meet at an point known as incenter. As the sum of interior angles of a triangle is 180°, there is only one possible right angle or obtuse angle possible in each triangle.

The sum of interior angle is 180

Given angles is 30, 90, x.

Therefore, sum is given by

90 + 30 + x = 180

120 + x = 180

x = 180-120

x = 60

Using the normal approximation to the binomial, it is found that there is a 35.57% probability that the number of individuals in Lance's sample is.

What is Normal Probability Distribution?

In a normal distribution with mean and standard deviation, the z-score of a measure X is given by:

z = x - [tex]\mu[/tex]/ [tex]\sigma[/tex]

Normal Probability Distribution measures how many standard deviations the measure is from the mean.  

In this problem:

The proportion of young adults ages 20–39 who regularly skip eating breakfast is given as 0.238, hence p = 0.238

A sample of 500 hence n = 500

The mean and the standard deviation are given by:

[tex]\mu[/tex] = 500 ( 0.238) = 119

[tex]\sigma[/tex] = 9.5225

The probability that the number of individuals in Lance's sample who regularly skip breakfast will be greater than 122, using continuity correction, then the p-value of Z when X = 122.5.

z = x - [tex]\mu[/tex]/ [tex]\sigma[/tex]

z = 122.5 - 119/ 9.5225

z = 0.37

Then p-value of 0.6443.

1 - 0.6443 = 0.3557.

Answers

          An algebraic expression known as a linear expression has terms that are either constants or variables raised to the first power. Alternatively put, none of the exponents can be greater than 1. As an illustration, while x is a variable raised to the first power, x2 is a variable raised to the second power. An illustration of a constant is 5.

Linear expression: what is it?

The number of deposits will change at a 100 percent rate.

Given that, consider the image of the linear function's graph.

Currently, the graph's two points are (3, 350) and (2, 250).

Rate of change is therefore equal to (250 - 350) / (2 - 3)

= -100/-1

 = 100.

The rate of change will therefore be 100 in relation to the number of deposits.

What is the equation of the line that passes through the point (-8,6) and has a slope of 1/4

Answers

The equation of the line is 4y = x + 32 which passes through the point (-8,6) and has a slope of 1/4.

We have been given the required line that passes through the point (-8,6) and has a slope of 1/4.

What is the slope of the line?

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Let the required line would be as

⇒ y - y₁ = m (x - x₁ )

The required line passes through the point (-8,6)

Here x₁ = -8 and y₁ = 6 and m = 1/4

Substituting these inputs into the above equation obtains the line equation.

⇒ y - 6 = 1/4 (x - (-8))

⇒ y - 6 = 1/4 (x + 8)

⇒ 4y - 24 = x + 8

⇒ 4y = x + 8 + 24

⇒ 4y = x + 32

Thus, the equation of the line is 4y = x + 32 which passes through the point (-8,6) and has a slope of 1/4.

The correct option is option D) it has range of 22

What is the range of a dataset?

It the difference between the minimum and maximum value of the dataset.

We are given a dataset with a histogram and we are asked to find out which of the given options does not describe the data

We find the answer by eliminating the correct option

Our given dataset contains 10 points

Hence the median will be the average of 5th and 6th element

Here the 5th and 6th elements are 17

Hence the median of the dataset is 17

Similarly 17 is repeated 4 times in the dataset. i.e highest number of times

Hence 17 is the mode of the dataset

If you look clearly at the histogram from median it is symmetrical that is left side equal to the right side

But if you look at the range the minimum value is 13 and maximum value is 21

Hence the range of the function is 21-13=8

And not 22

Answers

Answer: $31,200 per year

Step-by-step explanation:

The question tells us that they are working 40 hours a week and making 15 dollars an hour. We can find out how much they make a week and then multiply by 52 (number of weeks in a year) to find the amount they make in a year.

Per week:

15 * 40 = $600

Per Year:

600 * 52 = $31,200

Answer:

$31,285.74 per year

Step-by-step explanation:

What we know:

- $15 per hour

- 40 hour weeks

- 52.1429 weeks per year

What we need to find out:

- How much money per year

Step 1: Multiply for how much made per week

We know that we need $15 dollars for 40 hours so we start with multiplying them together to see how much we make a year.

40 x 15 = $600 per week

Step 2: Now multiply the amount of weeks a year by the amount made per week

So now we know that we make $600 per week now we have to multiply the amount of weeks in a year by the money made per week so.

52.1429 x 600 = $31,285.74 per year. So the house keeper makes $31,285.74 per year.

A solution needs to contain between 46% glucose and 50% glucose. Find the least and greatest amount of a 60% glucose solution that should be mixed with a 40% glucose solution in order to
end up with 30 kilograms of a solution containing the allowable percentage of glucose.

Answers

Answer:

least: 9 kggreatest: 15 kg

Step-by-step explanation:

You want the range of amounts of 60% solution that can be added to a 40% solution to achieve 30 kg of a solution that lies in the range of 46% to 50%.

Setup

Let x represent the mass in kg of 60% solution added. The fraction of the total solution that is glucose will be ...

  0.46 ≤ (0.60x +0.40(30 -x))/30 ≤ 0.50

Solution

Multiplying by 30 and simplifying the inequality, we have ...

  13.8 ≤ 0.20x +12 ≤ 15

  1.8 ≤ 0.2x ≤ 3 . . . . . . . . subtract 12

  9 ≤ x ≤ 15 . . . . . . . . . . divide by 0.2

The least amount of 60% solution that should be added is 9 kg. The greatest amount is 15 kg.

__

Check

  9 kg of 60% +21 kg of 40% has 5.4 +8.4 = 13.8 kg of glucose, the minimum.

  15 kg of 60% +15 kg of 40% has 9 +6 = 15 kg of glucose, the maximum.

(The minimum and maximum values are seen in the solutions steps after the initial multiplication by 30.)

The graph shows the printing rate of Printer A. Printer B can print at a rate of 25 pages per minute.
How does the rate for Printer B compare to the rate for Printer A? Use the drop-down menus to explain your answer.

Answers

The unit rate of Printer B = 25 pages per minute, which is greater than the unit rate of Printer A that is 15 pages per minute.

How to Find the Unit Rate of a Linear Graph?

The unit rate of a graph can b determined by using any point, (x, y), on the graph and solve by finding, m, which is the ratio of y to x, if x and y represents the variables of the relationship that is graphed.

Thus, unit rate (m) = y/x.

The printing rate for Printer A is represented by the graph. To find the unit rate for Printer A, use a point on the graph, (2, 30) to find the unit rate, m.

Printer A's Unit rate (m) = y/x = 30/2

Printer A's unit rate (m) = 15 pages per minute.

The printing rate for Printer B is given as 25 pages per minute. 25 pages per minute is a greater unit rate compared to 15 pages per minute.

Therefore, we can conclude that Printer B has a greater printing rate than Printer A, because the unit rate of 25 pages per minute is greater than 15 pages per minute.

[tex]\begin{gathered} 3x+2y=12 \\ x=\frac{2}{3}y \end{gathered}[/tex]

To solve the system of equation using substitution method only, here are the steps.

1. Since the 2nd equation has been equated already into x = or y = , we can use this value to substitute the "x" value in the first equation.

[tex]\begin{gathered} 3x+2y=12 \\ 3(\frac{2}{3}y)+2y=12 \end{gathered}[/tex]

2. Then, solve for y.

a. Eliminate first the parenthesis by multiplying the number outside it to the number inside it. (3 x 2/3y = 2y)

[tex]\begin{gathered} 2y+2y=12 \\ \text{Add similar terms.} \\ 4y=12 \\ \text{Divide both sides of the equation by 4.} \\ \frac{4y}{4}=\frac{12}{4} \\ y=3 \end{gathered}[/tex]

Therefore, the value of y is 3.

3. Plug in the value of "y" to either of the equation to solve for x. For this solution, we will plug it in to the second equation.

[tex]\begin{gathered} x=\frac{2}{3}y \\ x=\frac{2}{3}(3) \\ x=2 \end{gathered}[/tex]

The value of x = 2.

To check whether these values are true for both equations, we can plug them in.

P(k = 10) = (1[tex]0^{10[/tex] ×  [tex]e^{-10[/tex])/10! = 0.12511

P(k = 11) = (1[tex]0^{11[/tex] ×  [tex]e^{-10[/tex])/11! = 0.113736

The probability that more than 11 loads occur during a 4-year period is then given by the following Express

1 - [P(k = 0) + P(k = 1) + P(k = 2) + . . . + P(k = 11)]

substitute the values in the above equation, we get

= 1 - [0.000045 + 0.000454 + 0.00227 + 0.007567 + 0.018917 + 0.037833 + 0.063055 + 0.090079 + 0.112599 + 0.12511+ 0.12511 + 0.113736]

simplifying the equation, we get

= 1 - 0.571665 = 0.428335

C. How long must a time period be so that the probability of no loads occurring during that period is at most 0.3

(λ^0 * e^-λ)/0! = 0.3

⇒ e^-λ/1 = 0.3

simplifying the above equation, we get

⇒ e^-λ = 0.3

⇒ -λ = ln 0.3

⇒ -λ = -1.204

⇒ λ = 1.204

The time period = 4 years / 1.204

Time period = 3.2 years

millicoulombs.

Answers

The amount of charge on the capacitor after 0.06 seconds = 0.042 millicoulombs

What is an electric circuit?

An electric circuit is defined as the device that aids in transmission of electricity generated by a battery or a generator.

A capacitor is defined as the device that has the ability to store energy in an electric circuit.

The amount of charge in a capacitor decreases in one second by = 30%

The original charge on the capacitor = 1 millicoulombs

30 % of 1millicoulombs = 30/100 * 1 = 0.3

1millicoulombs - 0.3 millicoulombs = 0.7 millicoulombs .

If 0.7 millicoulombs = 1 second

X millicoulombs = 0.06 second

Make X millicoulombs the subject of formula;

X millicoulombs = 0.06 × 0.7 = 0.042 millicoulombs.

Under his cell phone plan, Rahul pays a flat cost of $36 per month and $4 per
gigabyte. He wants to keep his bill under $95 per month. Which inequality
can be used to determine g, the maximum number of gigabytes Rahul can use
while staying within his budget?

Answers

The inequality of the function is 36 + 4x < 95 and Rahul can use 14 gigabyte while staying within his budget

How to determine the inequality of the function?

The given parameters are:

Flat cost = $36 per monthRate per gigabyte = $4 per gigabyteRahul's bill = Under $95

The above means that;

The total charges per month is

C(x) = Flat cost + Rate per gigabyte x Number of gigabyte

So, we have

C(x) = 36 + 4x

For the bill to be under $95, we have

36 + 4x < 95

Solving further, we have

4x > 59

Divide by 4

x < 14.75

Hence, the inequality is 36 + 4x < 95

Find the measure of angle L. Round youranswer to the nearest degree.

Answers

Given the triangle KLM, you can find the measure of angle L by using the Law of Sines. This states that:

[tex]\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}[/tex]

Where "a", "b" and "c" are sides of the triangle, and "A", "B", and "C" are the angles.

In this case, you can set up this equation:

[tex]\frac{sinK}{k}=\frac{sinL}{l}[/tex]

Knowing that:

[tex]\begin{gathered} m\angle K=22\text{\degree} \\ k=56 \\ l=26 \end{gathered}[/tex]

You can substitute values into the equation and solve for "L". Remember the use the Inverse Trigonometric Function Arcsine, in order to solve for the angle:

[tex]\frac{sin(22°)}{56}=\frac{sinL}{26}[/tex][tex]\frac{26\cdot sin(22°)}{56}=sinL[/tex][tex]sin^{-1}(\frac{26\cdot sin(22°)}{56})=L[/tex][tex]m\angle L\approx10°[/tex]

Hence, the answer is:

[tex]m\angle L\approx10°[/tex]

When creating a graph, it is important to _____ the x and y axis?

Answers

"When creating a graph, it is important to assign the x and y axis."

Assigning the x and y axes is crucial when making a graph because the x-axis is referred to as the line on a Cartesian coordinate system that runs horizontally. A point or line's separation from the y-axis can be determined using the x-axis. The y-axis displays a point's location on a Cartesian plane in the y (vertical) direction. Additionally, it serves as the origin (zero) point for calculating how far a point is from the x-axis.

What is Graph?

A graph is a structure that resembles a set of objects in mathematics, more specifically in graph theory, in which some pairs of the objects are conceptually "related." The objects are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

What is x and y axis?

Two parallel lines, known as axes (pronounced AX-eez), that are perpendicular to each other make up a coordinate grid. Typically, the term "x-axis" refers to the horizontal axis. The y-axis is the common name for the vertical axis. The origin is the location where the x- and y-axes intersect.

"When creating a graph, it is important to assign the x and y axis."

Because the x-axis is referred to as the line on a Cartesian coordinate system that runs horizontally, determining the x and y axes is essential when creating a graph. The x-axis can be used to calculate a point or line's distance from the y-axis. A point's position on a Cartesian plane is shown on the y-axis in the y (vertical) direction. It also acts as the origin (zero) point for determining a point's distance from the x-axis.
