Step-by-step explanation:

When the graph represents direct variation, it passes through the origin (0, 0) and any points that have the same y/x ratio. Here, that ratio is 10/6 = 5/3, so points like (3, 5) and (9, 15) will be on the graph.

Answer:

<J = 60.26

<L = 28.84

JL = [tex]2\sqrt{65}[/tex]

Step-by-step explanation:

One is given that triangle (JKL) is a right triangle. The measurements for the legs (JK) and (KL) are given; (8) and (14) respectively. One can use the Pythagorean theorem to solve for the unknown side, the hypotenuse. The Pythagorean theorem states the following,

[tex]a^2+b^2=c^2[/tex]

Where (a) and (b) are the legs or sides adjacent to the right angle of the right triangle. (c) is the hypotenuse or the side opposite the right angle of the right triangle. Substitute in the given values and solve for the unknown,

[tex]a^2+b^2=c^2\\\\8^2+14^2=c^2\\\\64+196=c^2\\\\260=c^2\\\\2\sqrt{65}=c[/tex]

Now one has to find the unknown angles. This can be done using the right triangle trigonometric ratios. These ratios are used to describe the relationship between the sides and an angle of a triangle. These ratios are as follows,

[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adajcent}[/tex]

Bear in mind that the sides are named relative to the angle one is describing it from. Thus, the name of the (opposite) and (adjacent) sides change relative to the angle of description. However, the hypotenuse is the side opposite the right angle, this side never changes its name.

Solve for (<J)

Since one has the measures of all of the sides, one can use any ratio. In this case, let's use the ratio of tangent (tan).

[tex]tan(\theta)=\frac{opposite}{adjacent}\\\\\tan(\theta)=\frac{14}{8}\\\\\theta=tan^-1(\frac{14}{8})\\\\\theta=60.256[/tex]

Solve for (<L)

The sum of angles in any triangle is (180) degrees. One can use this property here. Form an equation by adding up all of the angle measures, and solve for (<L)

(<L) + (<J) + (<K) = 180

(<L) + 60.26 + 90 = 180

(<L) + 151.16 = 180

(<L) = 28.84

Answer:

Step 1: 180 (straight line)-156(interior angle)=24(exterior angle)

Step 2: 360÷24= 15 sides

Answer:

p2 = (-9 , -3)

Step-by-step explanation:

let p2 be (a , b)

given :

p1(-1 , 7) = (x1 , y1)

p2(a , b) = (x2 , y2)

using midpoint formula:

midpoint = (x1 + x2/2 , y1 + y2/2)

(-5 , 2) = (-1 + a/2 , 7 + b/2)

Now , compare corresponding elements

-5 = -1 + a/2

-5*2 = -1 + a

-10 = -1 + a

-10 + 1 = a

-9 = a

2 = 7 + b/2

2*2 = 7 + b

4 = 7 + b

4 - 7 = b

-3 = b

therefore p2 = (-9 , -3)

Answer: 0.973

Step-by-step explanation:

The probability mass function of geometric distribution is

[tex]f(x)=(1-p)^{x-1}p,\ \ \ x=1,2,3,...[/tex], p= probability of success on a trial.

As per given, we have

p=0.7

The probability that we'll have at most 3 orders [tex]P(X\leq3)=P(x=1)+P(x=2)+P(x=3)[/tex]

[tex]=(1-0.7)^{1-1}(0.7)+(1-0.7)^{2-1}(0.7)+(1-0.7)^{3-1}(0.7)\\\\=0.7+0.21+0.063\\\\=0.973[/tex]

hence, the required probability = 0.973

The probability that we'll have at most 3 orders will be "0.973".

According to the question,

→ [tex]x \sim Geometric (p)[/tex]

here,

p = 0.7

then,

→ [tex]P(X=x) = (1-p)^{x-1}\times p[/tex]

By putting the given values, we get

                   [tex]= (1-0.7)^{x-1}\times 0.7[/tex]

hence,

The probability that we'll have at most 3 orders will be:

→ [tex]P(X \leq 3)=P(X=1)+P(X=2)+P(X=3)[/tex]

                   [tex]=0.7+0.21+0.063[/tex]

                   [tex]=0.973[/tex]

Thus the above response is correct.

Step-by-step explanation:

The relative frequency for a 15% discount is 52.1%.

The relative frequency is the quotient of a particular frequency divided by the total number of frequencies.

Given:

A store is giving out cards labeled 1 through 10 when customers enter the store.

If the card is an even number, you get a 15% discount on your purchase that day.

The subgroup for even numbers = 2, 4, 6, 8, 10

The subgroup frequency = 56 + 50 + 54 + 49 + 54 = 263

The total frequency = 500

The relative frequency = 263/500 = 0.521 = 52.1%

Therefore, 52.1% is the relative frequency.

The population of interest: Male RCCC students.

Sample size: 31.

The sample mean: 69.68 inches.

Median: 69 inches.

Mode: 70 inches.

Range: 11 inches.

Standard deviation: 3.32 (rounded to 2 decimal places).

Variance: 11.02 (rounded to 2 decimal places).

We have,

Mean:

To find the mean, we sum up all the heights and divide by the total number of data points (31 in this case):

Mean = (70 + 70 + 70 + ... + 75) / 31

Mean ≈ 69.68 inches

Median:

The median represents the middle value in the dataset when arranged in ascending order. Since the dataset has an odd number of values (31), the median will be the value in the middle position when ordered:

Median = 69 inches

Mode:

The mode represents the value(s) that occur most frequently in the dataset. In this case, the mode is the height that appears most often:

Mode = 70 inches

Range:

The range is calculated by subtracting the minimum value from the maximum value in the dataset:

Range = Maximum height - Minimum height

Range = 75 - 64 = 11 inches

Standard Deviation (σ):

To find the standard deviation, we can use the formula that involves finding the difference between each value and the mean, squaring those differences, averaging them, and taking the square root:

Standard Deviation (σ) ≈ 3.32 (rounded to 2 decimal places)

Variance (σ²):

The variance is the square of the standard deviation.

We can square the value of the standard deviation to find the variance:

Variance (σ²) ≈ 11.02 (rounded to 2 decimal places)

The height dataset (in inches) for the 31 male RCCC students is as follows:

1 70

Answer:

[tex]\frac{2}{8} +\frac{2}{3} =\frac{12}{48} +\frac{32}{48} =\frac{44}{48} =\frac{11}{12}[/tex]

Step-by-step explanation:

To have a common denominator of 48, we need to solve for numerator and denominator!

[tex]\frac{2}{8} =\frac{12}{48}[/tex]        If you multiply the denominator by 6 just to get to 48, you must multiply it to the numerator as well.

[tex]\frac{2}{3} =\frac{32}{48}[/tex]        If you multiply the denominator by 16 just to get to 48, you must multiply it to the numerator as well.

Then we have those results in the line: [tex]\frac{12}{48} +\frac{32}{48}[/tex]

Then we added those fractions to get to 44/48 and simplify it by 4
