Answer: it’s 35 mi/h

Step-by-step explanation:  

The constant speed is 35 miles per hour. Therefore, option C is the correct answer.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

The slope of rate of change of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

From the graph,

Constant speed = 35 miles/1 hour

= 35 miles per hour

Therefore, option C is the correct answer.

Step-by-step explanation:

The probability that all the marbles are red is approximately 0.0010, rounded to four significant digits.

To find the probability that all four marbles drawn are red, we need to determine the number of ways to select four red marbles from the bag and divide that by the total number of ways to select any four marbles from the bag without replacement.

The number of ways to select four red marbles is given by:

C(5, 4) = 5

where C(5, 4) represents the number of combinations of 5 objects taken 4 at a time, which can be calculated as follows:

C(5, 4) = 5! / (4! * (5 - 4)!) = 5

The total number of ways to select any four marbles from the bag without replacement is given by:

C(20, 4) = 20! / (4! * (20 - 4)!) = 4845

where C(20, 4) represents the number of combinations of 20 objects taken 4 at a time.

Therefore, the probability that all four marbles drawn are red is:

5 / 4845 ≈ 0.0010

Therefore, the probability that all the marbles are red is approximately 0.0010, rounded to four significant digits.

Complete question is;

A mechanic sells a brand of automobile tire that has a life expectancy that is normally​ distributed, with a mean life of 34,000 miles and a standard deviation of 2500 miles. He wants to give a guarantee for free replacement of tires that​ don't wear well. How should he word his guarantee if he is willing to replace approximately​ 10% of the​ tires?

Answer:

The mechanics worded guarantee that the tyre will be replaced if it lasts less than or equal to 30796 miles.

Step-by-step explanation:

Let X = Life expectancy of the automobile tire

For the normal distribution, we are given;

μ = 34000

σ = 2700

Let y miles be the minimum miles of the tyres which the mechanic guarantees that he will replace if it's last less than that.

Now, since the mechanic is willing to replace approximately 10% of the tires, y would be such that:

P(X ≤ y) = 0.1

Using the z formula, we have;

P[(X - μ)/σ) ≤ [(y - μ)/σ] = 0.1

Thus;

P(Z ≤ ([y - μ]/σ) = 0.1

From z-distribution table the Z-score at 0.1 is approximately -1.2816

This is P(Z ≤ -1.2816)

Thus;

[y - μ]/σ = -1.2816

(y - 34000)/2500 = -1.2816

y - 34000 = -1.2816 × 2500

y - 34000 = -3204

y = 34000 – 3204

y = 30796

So, we conclude that the mechanic will guarantee that the tyre will be replaced if it lasts less than or equal to 30796 miles.

The volume of the two circular cylinders, each with radius r, whose axes intersect at right angles is  \(2\pi r^{3}\).

A cylinder whose bases are circular in shape and parallel to each other is called the circular cylinder.

To find the volume common to two circular cylinders with radius r, we first need to determine the shape of the intersection. Since the axes of the cylinders intersect at right angles, the intersection will be a rectangular solid with a circular base. The height of the solid will be 2r, since each cylinder has height 2r and they intersect in the middle.

To find the volume of this solid, we need to find the area of the circular base and multiply it by the height. The area of a circle with radius r is given by πr^2, so the area of the circular base is πr^2. Multiplying this by the height 2r gives us the volume of the solid:

Volume = \(\pi r^{2} * 2r\)

             = \(2\pi r^{3}\)

Therefore, the volume common to two circular cylinders with radius r, whose axes intersect at right angles, is  \(2\pi r^{3}\).

The approximate area of the window that is not cleaned by the wiper is:

What is circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.

To solve this problem, we need to find the area of the trapezoid and subtract the area of the semicircle.

The area of a trapezoid is given by the formula:

A = (a + b)h/2

where a and b are the lengths of the parallel sides, and h is the height (the perpendicular distance between the parallel sides).

In this case, we have:

a = 24 inches (the top parallel side)

b = 16 inches (the bottom parallel side)

h = 12 inches (the height)

Using the formula, we get:

A = (24 + 16) x 12/2

A = 240 square inches

The area of a semicircle is given by the formula:

A = πr²/2

where r is the radius of the circle.

In this case, the radius is half of the length of the wiper, so we have:

r = 16/2 = 8 inches

Using the formula, we get:

A = π(8²)/2

A ≈ 100.5 square inches

Therefore, the approximate area of the window that is not cleaned by the wiper is:

240 - 100.5 ≈ 139.5 square inches. Answer: \boxed{139.5}.

the limit of the given expression as x approaches 2 is 1/5.

To find the limit of the expression:

lim(x→2) [(ln(x + 3) - ln(5))/(x - 2)]

We can simplify it using logarithmic properties. Recall that the logarithmic property states:

ln(a) - ln(b) = ln(a/b)

Applying this property to our expression, we have:

lim(x→2) [ln((x + 3)/5)/(x - 2)]

Now, let's evaluate the limit:

lim(x→2) [ln((x + 3)/5)/(x - 2)]

By direct substitution, we get an indeterminate form of 0/0. We can use L'Hôpital's Rule to find the limit.

Applying L'Hôpital's Rule, we take the derivative of the numerator and the derivative of the denominator:

lim(x→2) [(1/(x + 3))/1]

Simplifying further, we have:

lim(x→2) [1/(x + 3)]

Now, we can substitute x = 2 into the expression:

lim(x→2) [1/(2 + 3)]

= lim(x→2) [1/5]

The percent yield of the experiment was calculated to determine the efficiency of the process. The answer will be presented in two paragraphs, with the first summarizing the findings and the second providing an explanation.

The percent yield of a chemical reaction is a measure of the efficiency with which a reaction produces the desired product. In this experiment, a student mixed 100 grams of Substance A with 150 grams of Substance B and collected 120 grams of dried product. To calculate the percent yield, we use the formula: (Actual yield / Theoretical yield) × 100%.

In this case, the actual yield is the amount of dried product collected, which is 120 grams. The theoretical yield is the maximum amount of product that could be obtained based on the amounts of the starting substances and the balanced equation for the reaction. Since the question doesn't provide information about the reaction or the balanced equation, we cannot determine the theoretical yield precisely. However, assuming the reaction goes to completion and all the starting substances are converted into product, the theoretical yield can be estimated.

Let's assume that the reaction is 100% efficient and all of Substance A and Substance B react to form the desired product. In that case, the total amount of starting substances is 100 grams + 150 grams = 250 grams. If the reaction goes to completion, the theoretical yield would be 250 grams. Using the formula for percent yield, we can calculate: (120 grams / 250 grams) × 100% = 48%. Therefore, the percent yield of the experiment is estimated to be 48%, with two significant digits to match the precision of the given data.

Step-by-step explanation:

First calculate for the area of the trapezoid (the formula is (base + base / 2) x height):

60 cm + 90 cm = 150 cm

150 cm / 2 = 75 cm

75 cm x 30 cm = 2250 cm²

Now 1 cm² = 1 mL and 1000 mL = 1 L

2250 cm² = 2250 mL

2250 mL = 2.25 L

The volume of the aquarium of height 100 cm and area of 2250 cm sq is 225L.

An aquarium has a trapezoid base. The base is 90 cm long at the front, 60 cm long at the back, and 30 cm wide (from front to back). The height is 100 cm.

The area of the trapezoid is calculated by measuring the sum of the parallel sides divided by 2 and multiplying it with its height.

A = [(a + b)/2] × h

The volume of the trapezoid is the product of the area of the trapezoid and the height between the trapezoid's end.

The volume of trapezoid = area × height between trapezium ends

so, the area of the trapezoid, A = [ 90 + 60 ]/2 × 30

= 150 /2 × 30

= 75 × 30

= 2250 \(\rm cm^{2}\)

The volume of trapezoid = area × height between trapezium ends

The volume of the trapezoid = 2250 × 100

                                                = 225000 \(\rm cm^{3}\)

Now, 1 cm² = 1 mL and 1000 mL = 1 L

225000 cm² = 225000mL

225000 mL = 225 L

Therefore, the volume of the aquarium of height 100cm and area of 2250 cm sq is 225L.

If all six bounds (limits of integration) are constant (numerical values, no variables) in cylindrical coordinates, then we must have a rectangular box-like region.

This is because in cylindrical coordinates, we have three variables: radius, angle, and height. When all six bounds are constants, we are essentially fixing the range of each variable, resulting in a rectangular box-like region.

In spherical coordinates, if all six bounds are constant, then we must have a rectangular pyramid-like region. This is because in spherical coordinates, we have three variables: radius, polar angle, and azimuthal angle. When all six bounds are constants, we are essentially fixing the range of each variable, resulting in a rectangular pyramid-like region.

It is not possible to have the exact same region represented with only constants in both cylindrical and spherical coordinates simultaneously. This is because the two coordinate systems have different geometric shapes and different ways of representing the variables. However, it is possible for the regions to have similar shapes and for the bounds to have similar numerical values in both systems.
