Answer: Which Option do You Drag and Drop into the Box?
Step-by-step explanation:
Let's call the number of rotations of the larger gear "L" and the number of rotations of the smaller gear "S". We know that when the larger gear completes 1 rotation, the smaller gear completes 1 3/4 rotations.
We can set up a proportion to solve for S:
S/1 3/4 = L/1/4
Simplifying the right side of the equation, we get:
S/1 3/4 = 4L
Multiplying both sides by 7/4 to get rid of the fraction on the left side, we get:
S = 28/4 L
Simplifying, we get:
S = 7L
This means that the smaller gear completes 7 rotations every time the larger gear completes 1 rotation.
Therefore, the correct value to drag and drop into the box is 7.

14 The people working for a company work in Team A or in Team B. number of people in Team A: number of people in Team B = 3/4; 4/5 of Team A work full time. 24% of Team B work full time. Work out what fraction of the people working for the company work full time. Give your fraction in its simplest form.
Answer:
Let's denote the number of people in Team A as a, and the number of people in Team B as b. From the problem, we know that:
a/b = 3/4
Now, we also know that 4/5 of Team A and 24% (or 24/100 = 6/25) of Team B work full time. So, the number of people working full time from Team A is 4a/5 and from Team B is 6b/25.
The total number of people working for the company is a + b, and the total number of people working full time is 4a/5 + 6b/25.
We are asked to find the fraction of people working full time, which can be represented as:
(4a/5 + 6b/25) / (a + b)
Firstly, we need to have a common denominator for the fractions, so we can express 4a/5 as 20a/25:
[tex](20a/25 + 6b/25) / (a + b)[/tex]
Simplifying, we can write this as:
[tex](20a + 6b) / (25(a + b))[/tex]
Now, since we know a/b = 3/4, we can substitute a = 3b/4 in the above expression:
[tex](20*(3b/4) + 6b) / (25((3b/4) + b))[/tex]
Simplifying the above, we get:
[tex](15b + 6b) / (25((3b/4) + b)) = 21b / 25b[/tex]
So, the fraction of people working full time is 21/25.

the typical american adult eats an average of 48.5 hamburgers in a year. assume the number of hamburgers eaten is normally distributed with a standard deviation of 8.3 pounds. find the probability that a randomly selected adult eats more than 40.0 hamburgers in a year.
The probability that a randomly selected adult consumes more than 40.0 hamburgers in a year is approximately 0.85.
In order to find the probability that randomly selected adult eats more than 40.0 hamburgers in a year, we use the normal distribution and z-scores.
First, we need to standardize the value of 40.0 using the formula : z = (x - μ)/σ,
Where : x = value we want to standardize (40.0 hamburgers), μ = mean number of hamburgers eaten (48.5 hamburgers), σ = standard-deviation (8.3 hamburgers),
Substituting the values,
We get:
z = (40.0 - 48.5)/8.3,
z = -1.024
Next, we find the area under the normal-curve to the right of z = -1.024. This represents the probability of randomly selecting an adult who eats more than 40.0 hamburgers.
We know that area to left of z = -1.024 is approximately 0.15. We need the area to right, so, we subtract this value from 1,
P(x > 40.0) = 1 - P(x ≤ 40.0)
P(x > 40.0) = 1 - 0.15
P(x > 40.0) ≈ 0.85,
Therefore, the required probability is 0.85.

Which type of compound event is generally associated with​ multiplication? Which is generally associated with​ addition?
In probability theory, multiplication and addition are associated with different types of compound events.
Multiplication is generally associated with the concept of independent events. When two events are independent, the probability of both events occurring is calculated by multiplying their individual probabilities. This is known as the multiplication rule of probability. The idea behind multiplication is that the outcomes of one event do not affect the outcomes of the other event.
On the other hand, addition is generally associated with the concept of mutually exclusive events. Mutually exclusive events are events that cannot occur at the same time. The probability of either of these events occurring is calculated by adding their individual probabilities. This is known as the addition rule of probability. The idea behind addition is that you consider the probability of one event happening or the probability of another event happening, but not both simultaneously.

evaluate the line integral where c is the given curve
∫c x sinyds C is line segment from (0 3) to (4 6)
Consider the line integral,
∫c x sin yds; C is the line segment from (0 3) to (4 6)
The value of the line integral is (-16/3)cos(6) + (16/9)sin(6). Evaluating this integral, you will get the value of the line integral for the given curve.
To evaluate the line integral ∫c x sin yds, where C is the line segment from (0,3) to (4,6), we first need to parameterize the curve. We can do this by letting x = t and y = 3 + (3/4)t, where t goes from 0 to 4. This gives us the parametric equations x = t and y = (3/4)t + 3.
Next, we need to find ds, the length of the curve element. We can use the formula ds = sqrt(dx^2 + dy^2) to get ds = sqrt(1 + (3/4)^2)dt = sqrt(25/16)dt = (5/4)dt.
Now we can substitute in our parameterization and ds into the line integral to get ∫c x sin yds = ∫0^4 t sin((3/4)t + 3) (5/4)dt.
We can evaluate this integral using integration by parts. Let u = t and dv = sin((3/4)t + 3) (5/4)dt, then du/dt = 1 and v = (-4/3)cos((3/4)t + 3). The integral becomes:
∫0^4 t sin((3/4)t + 3) (5/4)dt = uv|0^4 - ∫0^4 v du/dt dt
= (-4/3)t cos((3/4)t + 3)|0^4 - ∫0^4 (-4/3)cos((3/4)t + 3) dt
= (-4/3)t cos((3/4)t + 3) + (16/9)sin((3/4)t + 3)|0^4
= (-16/3)cos(6) + (16/9)sin(6)
Therefore, the value of the line integral is (-16/3)cos(6) + (16/9)sin(6).
To evaluate the line integral ∫c x sin y ds, where C is the line segment from (0, 3) to (4, 6), you first need to parameterize the curve C.
A possible parameterization is r(t) = (1-t)(0, 3) + t(4, 6) = (4t, 3+3t), with t ∈ [0, 1]. Then, compute the derivative dr/dt = (4, 3).
Now, find the integrand by replacing x and y with the parameterized curve components: x sin y = (4t) sin(3 + 3t).
Next, find the magnitude of the derivative: |dr/dt| = √(4² + 3²) = 5.
Finally, compute the integral:
∫[0, 1] (4t sin(3 + 3t))(5) dt.
Evaluating this integral, you will get the value of the line integral for the given curve.

Find the total surface area.
The total surface area is 640.56 in².
We have,
The TSA (Total Surface Area) of a cone is given by the formula:
TSA = πr² + πrℓ
Now,
We see that,
There are two cones so we find the TSA for both the cones and add them up to get the TSA.
So,
Cone 1:
r = 6 in
l² = r² + h²
l² = 36 + 64
l² = 100
l = 10
So,
TSA = πr² + πrℓ
= 3.14 x 36 + 3.14 x 6 x 10
= 113.04 + 188.4
= 301.44 in²
Cone 2:
r = 6 in
l = 12 in
TSA = πr² + πrℓ
= 3.14 x 6 x 6 + 3.14 x 6 x 12
= 113.04 + 226.08
= 339.12 in²
Now,

determine whether the mean, median, or mode would be the best choice to describe the center of the following set of data. an elementary school has 92 first graders. depending on when their birthday falls, the first graders might be six, seven, or eight on the last day of the school year. would it be best to use the mean, median, or mode to describe the typical age of the first-graders?
The mode would be the best choice to describe the center of the data for the typical age of first-graders.
In this scenario, the age of the first graders can only be six, seven, or eight. Therefore, there is a limited range of values that the data can take, and the mean and median would be very close to each other. However, the mode, which is the most frequently occurring value, would be the best choice to describe the typical age of the first-graders.
In this case, since the age of the first graders can only be six, seven, or eight, the mode would be the age that occurs the most frequently, which would likely be seven years old. Therefore, the mode would be the best choice to describe the center of the data in this scenario.
