Answer: B, $1.56

Step-by-step explanation:

The unit price is simply the price of a good per unit. In this case, the price per pound.

Divide the cost by the number of pounds.

18,75/12 = ~1,56

Therefore, Option B is the correct answer.

Two-and-four-fifths is less than three-and-one-half.

The correct option is B.

A fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.

For example, 5/10 is a fraction.

Here, 5 is a numerator and 10 is a denominator.

Comparing two-and-four-fifths and three-and-one-half.

two-and-four-fifths = [tex]2\frac{4}{5}[/tex]

three-and-one-half = [tex]3\frac{1}{2}[/tex]

Changing them from mixed fractions to improper fractions

[tex]2\frac{4}{5} = \frac{14}{5} \\\\3\frac{1}{2} = \frac{7}{2}[/tex]

We can deduce that [tex]\frac{14}{5}[/tex] < [tex]\frac{7}{2}[/tex]

Answer:

Increasing: [tex](-\infty,-\frac{4}{3})\cup(\frac{4}{3},\infty)[/tex]

Decreasing: [tex](-\frac{4}{3},\frac{4}{3})[/tex]

Step-by-step explanation:

A continuous function increases where [tex]f'(x) > 0[/tex] and decreases where [tex]f'(x) < 0[/tex], so let's find our critical points:

[tex]f(x)=3x^3-16x+2\\f'(x)=9x^2-16\\[/tex]

[tex]9x^2-16=0\\\\9x^2=16\\\\x^2=\frac{16}{9}\\\\x=-\frac{4}{3},\frac{4}{3}[/tex]

We'll use [tex]x=-2, x=0, \text{and } x=2[/tex] as test points to see how the derivative's behavior is around the critical points:

[tex]f'(-2)=9(-2)^2-16=9(4)-16=36-16=20 > 0[/tex]

[tex]f'(0)=9(0)^2-16=-16 < 0[/tex]

[tex]f'(2)=9(2)^2-16=9(4)-16=36-16=20 > 0[/tex]

Hence, we can see that f(x) increases on the interval [tex](-\infty,-\frac{4}{3})\cup(\frac{4}{3},\infty)[/tex] and decreases on the interval [tex](-\frac{4}{3},\frac{4}{3})[/tex].

When the ferris wheel rotates once every four minutes, your seat will be above 15 meters for 77.4 seconds of each revolution.

The spikes that go through the middle of a cycle's wheel from one end to the other are an illustration of diameter. Since the diameter is the line segment that begins at one end of a circle and finishes at the other end of the circle, passing through the center, we can compare this to the diameter of a circle. The diameter of a circle cuts through the center, whereas the radius circumscribes the circle from edge to edge. The size of a circle essentially divides it in two. the distance in a straight line going from one edge of a tumor or other item, through the middle, and out the other edge.

Find out your answer below:

"If a coin is tossed 7 times, what is the probability of getting 4 tails?"

Use the binomial distribution directly. Let us assume that the number of tails is represented by x  (where a result of tails is regarded as success) and in this case X = 4

Assuming that the coin is unbiased, you have a probability of success ‘p’(where p is considered as success) is 1/2 and the probability of failure ‘q’ is 1/2(where q is considered as failure). The number of trials is represented by the letter ’n’ and for this question n = 7.

Now just use the probability function for a binomial distribution:

P(X = x) = nCxpxqn-x

Using the information in the problem we get P(X = 4) = (7C5)(1/2)5(1/2)2

= 21 × 1/32 × 1/4

= 21/128

Hence, the probability of flipping a coin 7 times and getting tails 4 times is 21/128.

The area of the shaded regions is 4π - 8

From the question, we have the following parameters that can be used in our computation:

We start by calculating the area of the triangle using

Area of triangle = 1/2absin(C)

Substitute the known values in the above equation, so, we have the following representation

Area of triangle = 1/2 * 4 * 4 * sin(90 degrees)

Evaluate

Area of triangle = 8

Next, we calculate the area of the semicircle using

Area = 0.125πd²

Where

d² = (4² + 4²) = 32

So, we have

Area semicircle = 0.125π * 32 = 4π

The area of the circle is

Area circle = 0.25πd²

This gives

Area circle = 0.25π * 32 = 8π

The area of the shaded regions is

Shaded region = circle - semicircle - triangle

Substitute the known values in the above equation, so, we have the following representation

Shaded region =  8π - 4π - 8

Evaluate

Shaded region =  4π - 8

T(t) = Temperature at time t

T(s) = Temperature of the surroundings

k = Rate of cooling

t = time taken

108 = 65 + (207 - 65)e^-2k

108 - 65 = (207 - 65)e^-2k

43 = 142e^-2k

43/142 = e^-2k

-2k = ln(0.3)

k = ln(0.3)/-2

k = 0.6

Thus;

At t = 4

T(t) = 65 + (207 -65)e^-4 *0.6

T(t) = 78

For T(t) = 75℉

75 = 65 + (207 -65)e^-t *0.6

The true statement about students enrolled in this course from

2018 to 2019 is B The absolute change is -253 students and the relative change indicates a decrease of 7%.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Given that In the year 2018, the students enrolled were 700 and in the year 2019the students enrolled were 475.

Therefore, Initial value = 700 and Final value = 475.

The absolute change is -

Absolute change = Final value - Initial value =447 - 700 =- 253

The relative change is -

Relative change = Final value - Initial valueInitial value×100% =475-700/ 700×100% =-253

700×100% =-7%

Slope-intercept form is a common way of representing linear functions. Slope-intercept is written as y = mx + b, where m is the slope and b is the y-intercept.

Slope

To find the slope-intercept equation we first need to find the m-value. Slope is often defined as rise over run. This means the change in y divided by the change in x. So, we can find the slope by counting how much the y-value and the x-value increases between 2 points.

For example, we can take the points (2,5) and (4,6). The y-value increases by 1 and the x-values increase by 2. This means that the slope is 1/2. We can plug this into slope-intercept form to get part of the equation: [tex]y = \frac{1}{2}x+b[/tex].

Y-Intercept

Next, we need to find the b-value. The y-intercept of a graph is the y-value where the function intersects with the y-axis (the vertical axis). By looking at the graph, we can tell that the function crosses the y-axis at y = 4; this occurs at the point (0,4). The y-intercept always occurs when x = 0.  

Now, we can plug 4 in for b to get the final equation: [tex]y=\frac{1}{2}x +4[/tex].

The rate of speed that a vehicle must travel to cover 132 kilometers in one and a half hours is 88 kilometers per hour.

The rate of speed is the quotient of distance and time.

Similarly, the time taken to cover a distance can be determined as the quotient of distance and speed.

The formula describing the relationship between distance traveled, speed, and time is Distance = Rate of Speed x Time.

The total distance traveled = 132 kilometers

The time taken to travel the distance = 1¹/₂ hours = 1.5 hours

Rate of speed = Distance/Time
