Answer:

20 cubic inches

Step-by-step explanation:

\(1 * 4 * 5 = 20\)

The length of arc WX is (10/3)π, expressed as a fraction times π.

To find the length of the arc WX, we need to determine the measure of the central angle corresponding to arc WX. Since ∠WVX is an inscribed angle, its measure is equal to half the measure of its intercepted arc WX. Therefore, the measure of arc WX is 2 × 50° = 100°.

The length of an arc in a circle is given by the formula:

Arc Length = (θ/360°) × 2πr

Where θ is the measure of the central angle in degrees and r is the radius of the circle.

Given that the radius of the circle is 6, we can substitute the values into the formula:

Arc Length = (100°/360°) × 2π × 6

Simplifying:

Arc Length = (5/18) ×2π × 6

Arc Length = (10/3)π

Therefore, the length of arc WX is (10/3)π, expressed as a fraction times π.

Answer:

F = -22°F

Step-by-step explanation:

Use the9 given equation to convert Celsius to Fahrenheit.

F = 9/5 C + 32

They want to know what -30°C is in Fahrenheit.

Fill in -30 for C in the equation.

F = 9/5 (-30) + 32

Multiply first, before adding. In order to multiply the fraction × the -30, times

-30 ×9 and then divide by 5. (Or for easier mental math, times -30÷5 and then times that answer (-6) times 9.)

F = -54 + 32

F = -22

This means that -30°C is the same as -22°F.

The coordinates of the vertices of its image include the following:

C. A' (-3, 2).

   B' (0, 2).

   C' (0, 4).

In Geometry, the rotation of a point 90° about the center (origin) in a counterclockwise (anticlockwise) direction would produce a point that has these coordinates (-y, x).

By applying a rotation of 90° counterclockwise to the vertices of triangle ABC, the coordinates of the vertices of the image are as follows:

(x, y)               →     (-(y - b) + a, (x - a) + b)

A (2, 5)           →     (-(5 - 1) + 1, (2 - 1) + 1) = (-(4) + 1, (1 + 1) = A' (-3, 2).

B (2, 2)           →     (-(2 - 1) + 1, (2 - 1) + 1) = (-(1) + 1, (1 + 1) = B' (0, 2).

The mean and standard deviation of the number of people with blood type a-positive in 100 randomly selected is μ=85, σ=3.5707

The standard deviation is a statistic that measures the amount of variation or dispersion of a group of values.

Standard deviation is usually abbreviated SD and is most commonly represented in mathematical texts and equations by the lower case Greek letter (sigma) for population standard deviation or the Latin letter s for sample standard deviation.

A low standard deviation indicates that the values are close to the mean of the set (also known as the expected value), whereas a high standard deviation indicates that the values are spread out over a broader range.

Given, The population proportion of success is p=0.85

And also given that the sample size is n=100

b) The population mean is:

μ=np

μ=100(0.85)

μ=85

Therefore, mean=85

And the population standard deviation is:

σ=√np(1-p)

σ=√100(0.85)(1-0.85)

σ=3.5707

Therefore, standard deviation=3.5707

Step-by-step explanation:

The width of the enclosure is 7 feet.

The formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length and W is the width. Since the length of the enclosure is given as 11 feet and the total length of fencing used is 36 feet,

we can set up an equation:

P = 2L + 2W = 36

Substituting the given value of L, we have:

2(11) + 2W = 36

Simplifying the left side, we get:

22 + 2W = 36

Subtracting 22 from both sides, we get:

2W = 14

Dividing both sides by 2, we get:

W = 7

answer: $650

To find how much Kendra paid per foot, we can divide the total cost of the fencing by the length of the fencing.

The length of the fencing is given as 50 feet.

The total cost of the fencing can be found by multiplying the cost per foot by the length of the fencing:

Total cost = Cost per foot x Length of fencing Total cost = $13/ft x 50 ft Total cost = $650

Therefore, Kendra paid a total of $650 for 50 feet of fencing. To find how much she paid per foot, we can divide the total cost by the length of the fencing:

Cost per foot = Total cost / Length of fencing Cost per foot = $650 / 50 ft Cost per foot = $13/ft

So Kendra paid $13 per foot of fencing.

Hooke's Law is a principle in physics that states that the force required to extend or compress a spring by some distance is proportional to that distance. In other words, the more you stretch or compress a spring, the more force it will take, and the proportionality constant between force and distance is called the spring constant.

To find the constant k, we can use the given information that when the mass is 10 kg, the spring stretches 6 cm:

l(10) = k(10) + b

6 = 10k + b

To find the constant b, we can use the given information that when the mass is 0 kg, the spring stretches 50 cm:

l(0) = k(0) + b

50 = 0 + b

Substituting the value of b into the equation for l(10), we get:

6 = 10k + 50

-44 = 10k

k = -4.4

Therefore, the function rule is:

l(w) = (-4.4)w + 50

To find the mass of an object in the pan if the spring is stretched to a length of 65 cm, we can substitute l = 65 into the equation for l(w):

65 = (-4.4)w + 50

15 = (-4.4)w

w = 15/(-4.4)

w = 3.409090909090909

Answer:

  acute scalene triangle

Step-by-step explanation:

The largest angle is acute, and all sides are different lengths. The triangle is an acute scalene triangle.

____

The magnitudes of the coordinate differences are ...

  WX = (7, 5), XY = (2, 7), WY = (9, 2)

The two sides that are closest in length are ...

  WX = √(49+25) = √74

  WY = √(81 +4) = √85

Obviously, these are different lengths.

You can get a clue by comparing the numbers whose squares you are adding:

  7^2 +5^2 > 7^2 +2^2 . . . . . WX > XY

  9^2 +2^2 > 7^2 +2^2 . . . . WY > XY

so, the only question is relation between WX and WY. We note that the length of WX is less than one of the coordinate differences of WY, so we know WY is the longest. (√74 < 9)

We can tell from the graph that angle X (opposite longest side WY) is an acute angle, so the triangle is acute.

The discrete probability distribution of P(X> 5) is 0.62

A discrete probability distribution and a continuous probability distribution are two types of probability distributions that define discrete and continuous random variables respectively. A probability distribution can be defined as a function that describes all possible values of a random variable as well as the associated probabilities.

The find P(X > 5), we need to sum the probabilities of all the values of X that are greater than 5.

To find the missing probabilities, we know that the sum of all probabilities must equal 1. So, we can set up an equation:

0.08 + 0.15 + 0.15 + 0.15 + 0.06 + 0.?? + 0.?? = 1

Solving for the missing probabilities, we get:

0.08 + 0.15 + 0.15 + 0.15 + 0.06 + 0.24 + 0.17 = 1

So, P(X = 8) = 0.24 and P(X = 9) = 0.17

Now, we can sum the probabilities of all values of X that are greater than 5:

P(X > 5) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9)

P(X > 5) =  0.15 + 0.06 + 0.24 + 0.17

P(X > 5) = 0.62

The rate at which the water level is rising when the water level is 6 cm is approximately 2.67 cm/s. if an inverted pyramid is filled with water at a constant rate of 55 cubic centimeters per second, the top of pyramid is in square shape with length of 8 cm and height of 14 cm.

Let's call this rate "r".

Volume of pyramid = (1/3) * base area * height

Since the pyramid has a square base, the base area is given by

Base area = (side length)^2

Substituting the given values

Base area = (8 cm)^2 = 64 cm^2

Height = 14 cm

V = (1/3) * 64 cm^2 * 14 cm = 298.67 cm^3

We know that the water is being added to the pyramid at a constant rate of 55 cm^3/s. Therefore, the rate at which the volume is increasing is

dV/dt = 55 cm^3/s

We also know that the volume of water in the pyramid at any given time is given by

V_water = (1/3) * base area * h_water

where h_water is the height of the water at that time.

To find the rate at which the water level is rising (r), we need to find dh_water/dt. We can do this by taking the derivative of both sides of the equation for V_water with respect to time

dV_water/dt = (1/3) * base area * dh_water/dt

Substituting the known values

dV_water/dt = (1/3) * (8 cm)^2 * dh_water/dt

dV_water/dt = (64/3) cm^2 * dh_water/dt

dh_water/dt = 3 * dV_water/dt / 64

dh_water/dt = 3 * 55 cm^3/s / 64 = 2.67 cm/s

Standard deviation= sqrt [(p * q) / n]

Where p= proportion of success

             = 2/5

           q= proportion of failure

             = 1 - p

             = 1 - 2/5

             = 3/5

n= sample size

 = 50

Standard deviation= sqrt [(2/5 * 3/5) / 50]

                               = sqrt (6/1250)

                               = sqrt (0.0048)

                               = 0.069

Step 5: Write the final answer.

The population mean for the proportion of customers who use Crest toothpaste is 2/5, and the standard deviation is 0.069.
