Hillary works at a video store. She earns $8. 50 per hour plus 12% commission on all the weekly sales she makes. If she works 24 hours in a week, which expression best describes her sales (x) if she earns at least $324 during that week

The actual time it took Tory to travel 30 km is 0 hours.

As per the data given in the question,

Speed of the boat of both the person Tory and Emillio are same.

Let's call the time it took Tory to travel 30 km as "t" (in hours).

Emilio travelled for t + 3 hours, and during that time, he covered a total distance of 100 km.

So, we can write the equation:

30 + (t + 3) * 30 = 100

Solving for t:

30 + 30t + 90 = 100

30t = -60

t = -2

Since time cannot be negative, the actual time it took Tory to travel 30 km is 0 hours.

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

Let X be a random variable representing the minimum value among 20 fair six-sided dice rolls. We are interested in finding P(X = 1).

The event {X = 1} occurs if and only if all 20 dice rolls result in a 1. The probability of a single dice rolling a 1 is 1/6, and the rolls are independent, so the probability of all 20 dice rolling a 1 is (1/6)^20. Hence,

P(X = 1) = (1/6)^20 = 1.275 * 10^-9.

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

The histogram doesn't support Alfonso's claim and the correct option is 5: No, the distribution is skewed to the left with a mean age greater than 36.

What is a histogram?

A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.

Consider the given histogram at the photo below. It is an left-skew histogram, since it has a long tail to the left side.

We need to estimate the mean of the given data. To do so, we need to multiply each class midpoint with its probability, and sum them.

For example, for the first one, the midpoint is 32 and the probability is 0.03 (read the value on the y-axis). For, the second one, the midpoint is 33 and the probability is 0.04, for the third the midpoint is 34 and the probability is 0.05, and so on. All needed values are presented below.

1. midpoint = 32, probability= 0.03

2. midpoint = 33, probability = 0.04

3. midpoint = 34, probability = 0.05

4. midpoint = 35, probability = 0.1

5. midpoint = 36, probability =0.11

6. midpoint = 37, probability = 0.13

7. midpoint = 38, probability = 0.2

8. midpoint = 39, probability = 0.09

So, it is obtained that -

μ = 0.03 · 32 + 0.04 · 33 + 0.05 · 34 + 0.10 · 35 + 0.11 · 36 + 0.13 · 37 + 0.25 · 38 + 0.20 · 39 + 0.09 · 40

μ = 37.15

20 feet per minute is equal to 400 yards/hour

What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

For 1 minute 20 feet

For 60 minutes , 60*20=1200 feet

1 hour = 60 minutes

Thus, we have 1200 feet per hour

3 feet = 1 yard

So, 1200 feet = 1200/3 yrads = 400 yards

(a) The probability that an assembly will have exactly one defect is 0.2.

This can be calculated using the Poisson distribution formula, which states that the probability of a given number of events (in this case, defects) occurring in a given interval is equal to the mean number of events (in this case, defects) multiplied by the exponential of the mean number of events (in this case, defects).

And multiplied by the exponential of the mean number of events (in this case, defects) multiplied by the exponential of the mean number of events (in this case, defects) divided by the factorial of the given number of events (in this case, defects). Thus, the probability of an assembly having exactly one defect is 0.2.

(b) The probability of an assembly having one or more defects is 1 - 0.2 = 0.8. This can be calculated using the same formula as in (a).

Step-by-step explanation: 4/1 is going rise/run. your rise would be 4 and your run would be 1. 4/1 is up 4 to the right 1. another point would be (0,-2). you are still gonne do the same thing as rise over run just go negavtive. -4/1 which is down 4 to the left 1.

The answer to this question requires the use of the Poisson distribution and the cumulative distribution function.

(a) We are asked to find the probability that the fourth person weighed is the first person to be overweight. Since 63% of Americans are overweight, this means that the probability of a randomly selected American being overweight is 0.63. The probability of the first overweight person being the fourth person weighed is given by P(X=3) where X is the number of overweight people in the first 4 people weighed. Using the binomial distribution formula, we have:

[tex]P(X=3) = (4 choose 3) * (0.63)^3 * (0.37)^1\\\\ = 4 * (0.63)^3 * (0.37)[/tex]

(b) We are asked to find the probability that it takes more than 4 people to observe the first overweight person. This is equivalent to finding the probability that none of the first 4 people weighed are overweight. Using the complement rule, we have:

[tex]P(X=0) = 1 - P(X > 0)\\\\ = 1 - [P(X=1) + P(X=2) + P(X=3) + P(X=4)]\\\\ = 1 - [ (4 choose 1) * (0.63)^1 * (0.37)^3 + (4 choose 2) * (0.63)^2 * (0.37)^2 + P(X=3) ][/tex]

(c)  The expected value (mean) of a binomial distribution is given by μ = np, where n is the number of trials and p is the probability of success in each trial. In this case, n=4 and p=0.63. Thus, the mean number of overweight people in 4 trials is 4 * 0.63 = 2.52. The variance of a binomial distribution is given by σ^2 = np(1-p), so in this case the variance is 4 * 0.63 * 0.37 = 1.41. The standard deviation is the square root of the variance, so the standard deviation is approximately [tex]\sqrt{(1.41) } = 1.19[/tex]. This means that the number of overweight people in 4 trials is expected to be around 2.52, with a standard deviation of 1.19.

For an nth root, there are n solutions of the equation z^n = ω.

To find these solutions, we use the polar form of z = r * e^(iθ). Substituting into the equation, we get:

r^n * e^(iθn) = s * e^iφ

Comparing the magnitude of both sides, we have:

r^n = s

Comparing the phase of both sides, we have:

nθ = φ + 2πk (where k is an integer)

So, we can set:

r = s^(1/n)

θ = (φ + 2πk) / n

Therefore, the n solutions are:

z = s^(1/n) * e^(i(φ + 2πk) / n)

The average rate of change and the instantaneous rate of change are same for ƒ(x) = 2x + 5. The solution has been obtained by using the concept of rate of change.

What is rate of change?

The pace at which one quantity changes in relation to another is described by the rate of change function. Simply expressed, the amount of change in one item is divided by the same amount of change in another to determine the rate of change. The relationship between how one quantity changes in relation to a change in another quantity is provided by the rate of change formula.

The average rate of change is:

[tex]r_{avg} =\frac{f(b)-f(a)}{b-a}[/tex], on interval [a,b]

Here, we are given  ƒ(x) = 2x + 5

So,

[tex]r_{avg} =\frac{(2b+5)-(2a+5)}{b-a}[/tex]

[tex]r_{avg} =\frac{2b-2a}{b-a}[/tex]

[tex]r_{avg} =2[/tex]

The slope of f assessed at a single point, such as f′(c), where c is a predetermined point, is the definition of the instantaneous rate of change.

So, for ƒ(x) = 2x + 5,

f′(c) = 2

Therefore, instantaneous rate of change is 2.

Hence, the average rate of change and the instantaneous rate of change are same for ƒ(x) = 2x + 5.
