Answer:

94.2

Step-by-step explanation:

Arc length is basically circumference.

Circumference formula: 2πr

All we need is the radius.

Radius = r

15 x 2 = 30 (diameter)

Then we are going to multiply by pi.

Arc length = 30π OR 94.2

The criterion that is least likely to be used in choosing bins (classes) in a frequency distribution is personal preference or subjective judgment.

When constructing a frequency distribution, it is important to consider objective criteria based on the nature of the data and statistical principles. Common criteria used for choosing bins include the range of the data, the desired number of bins, the shape of the data distribution, and the purpose of the analysis. These criteria help ensure that the bins effectively capture the variation in the data and provide meaningful insights. Personal preference or subjective judgment, on the other hand, may introduce bias and lack objectivity in determining the bin boundaries. It is essential to rely on objective criteria and statistical guidelines to make informed decisions when choosing bins for a frequency distribution.

Answer:

Step-by-step explanation:

we are given opposite and adjacent if the given right angle triangle

we want to make an equation with the given information

notice that adjacent is greater than opposite so we can only take 30° as our angle

hence,

using trigonometric property

our equation is

[tex] \displaystyle \: \tan( {30}^{ \circ} ) = \frac{h + 1}{6} [/tex]

we took tangent function because we know that tangent function is the ratio of opposite and adjacent

now let's solve the equation

recall unit circle:

[tex] \displaystyle \: \frac{ \sqrt[]{3} }{3} = \frac{h + 1}{6} [/tex]

cross multiplication:

[tex]3(h + 1) = 6 \sqrt{3} [/tex]

divide both sides by 3:

[tex]h + 1 = 2 \sqrt{3} [/tex]

cancel 1 from both sides:

[tex] \therefore \: h = 2 \sqrt{3} - 1[/tex]

by using mental math

The angle of elevation at the top of a tower at a point on the ground is 30° at a distance of 6 metre from the foot and the height of the tower is h+1. find h

now this question verifies the equation

because we are given a right angle triangle where the opposite is less than the adjacent so we took 30° as our angle

by solving the equation we'll again get our answer

Answer:

4 hours and 40 minutes

Step-by-step explanation:

450g = kg

450g = 0.45 kg

We will use ratios:

[tex]\frac{20}{0.45} =\frac{x}{6.3} \\\\0.45x=126\\x=280[/tex]

280 mins =

4 hours and 40 minutes

4(60) + 40

240 + 40

Answer:

Step-by-step explanation:

The point-slope form of the equation of the line passing point (x₁, y₁) and with the slope of m is:  y - y₁ = m(x - x₁)

m = -⁶/₅

Y-Intercept = 2  ⇒  point (0, 2)  ⇒  x₁ = 0,  y₁ = 2

Point-Slope Form:    y - 2 = -⁶/₅(x - 0)

Answer:

child = $14

senior = $8

Step-by-step explanation:

3s + c = 38

3s + 2c = 52

52 - 38 = 14

child = $14

3s + 14 = 38

3s = 24

divide by 3

senior = $8

Answer:

Rectangular Prism → h = 2in

                                    B = 143in

                                    P = 48in

Surface Area = 382in²

Lateral Surface Area = 96in²

Triangular Prism → h = 7in

                                B = 20in

                                P = 27in

Surface Area = 229in²

Lateral Surface Area = 189in²

Triangular Prism → h = 10in

                                B = 120in

                                P = 60in

Surface Area = 840in²

Lateral Surface Area = 600in²

Step-by-step explanation:

Formulas: Total Surface Area = 2B = Ph

                  a²+b²=c²

                  Area = [tex]\frac{1}{2}[/tex]bh

                  Lateral Area = Ph

Step-by-step explanation:

Por Geometría sabemos lo siguiente:

Angulo recto - Dos semirrectas con origen común y cuya medida angular es mayor a 0° y menor a 90°.

Angulo obtuso - Dos semirrectas con origen común y cuya medida angular es mayor a 90° y menor a 180°.

Angulo recto - Dos semirrectas con origen común y cuya medida angular es igual a 90°.

Angulo llano - Dos semirrectas con origen común y cuya medida angular es igual a 180°.

Finalmente, presentamos un dibujo representativo de los cuatro tipos de ángulos.

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.

To find probability we can use the properties of the normal distribution.

Given,

Mean (μ) = $958

Standard deviation (σ) = $144

Sample size (n) = 99

We want to find the probability P(934.8 < X < 965.2).  X represents the mean value of a randomly selected policy.

Calculate z-score for the lower value.

z1 = (934.8 - μ) / (σ / sqrt(n))

Calculate z-score for the upper value.

z2 = (965.2 - μ) / (σ / sqrt(n))

Cumulative probability between the z-scores.

P(934.8 < X < 965.2) = P(z1 < Z < z2)

If P(Z < z1) = 0.2658. P(Z < z2) = 0.8477. The probability of interest would be.

P(934.8 < X < 965.2) = P(z1 < Z < z2) = P(Z < z2) - P(Z < z1) = 0.8477 - 0.2658 = 0.5819

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.
