Answer:

Step-by-step explanation:

We can use the two given data points to find the slope of the line that represents the population growth over time.

The population at time t=3 is 1285, which means that the population has increased by P1 = 1285 - P0, where P0 is the initial population at time t=0 (which is not given). Similarly, the population at time t=8 is 2460, which means that the population has increased by P2 = 2460 - P0.

The time elapsed between t=3 and t=8 is 8-3 = 5 years.

The slope of the line that represents the population growth over time is given by:

slope = (P2 - P1) / (t2 - t1)

where t1 and t2 are the corresponding times.

Substituting the given values, we get:

slope = (2460 - 1285) / (8 - 3)

slope = 235

This means that the population is increasing by 235 people per year.

To find the initial population at time t=0, we can use either of the two given data points. Let's use the population at time t=3:

P1 = 1285 - P0

235 * 3 = 705

1285 - 705 = 580

Therefore, the initial population at time t=0 (i.e., in the year 1990) was 580 people.

We can now use the slope to find the population at any given time t after 1990.

Let P(t) be the population at time t after 1990.

Then, P(t) = P0 + slope * (t - 0)

P(t) = 580 + 235t

For example, the population in the year 2000 (i.e., when t=10) would be:

P(10) = 580 + 235(10) = 3330

Therefore, the population in the year 2000 would be 3330 people.

The measure of arc KL can be found using the fact that angles in the same segment are equal. The angles m arc KL = m arc KLI = 247 degrees.

In geοmetry, a circle is a twο-dimensiοnal shape cοnsisting οf all pοints that are a fixed distance (called the radius) frοm a given pοint (called the center). A circle is a set οf pοints that are equidistant frοm the center. The distance between any pοint οn the circle and the center is called the radius, and the distance acrοss the circle passing thrοugh the center is called the diameter.

The measure of angle JLI can be found using the fact that angles on a straight line add up to 180 degrees. Therefore,

m angle JLI = 180 - m angle LKJ = 180 - 124 = 56 degrees.

The measure of arc JKI can be found using the fact that the measure of an inscribed angle is half the measure of the arc it intercepts. Therefore,

m arc JKI = 2 * m angle JLI = 2 * 56 = 112 degrees.

Therefore, The measure of arc KL can be found using the fact that angles in the same segment are equal. The angles m arc KL = m arc KLI = 247 degrees.

Answer:

Answer: (a) The probability of being male or being a nursing major is the sum of the probabilities of being male and being a nursing major, minus the probability of being both male and a nursing major (since this intersection is counted twice):

P(being male or being nursing major) = P(male) + P(nursing major) - P(male and nursing major)

From the table, we have:

P(male) = 1110/3538 ≈ 0.314

P(nursing major) = 1016/3538 ≈ 0.287

P(male and nursing major) = 94/3538 ≈ 0.027

Therefore:

P(being male or being nursing major) ≈ 0.314 + 0.287 - 0.027 ≈ 0.574

Rounded to the nearest thousandth as needed, the probability of being male or being a nursing major is approximately 0.574.

(b) The probability of being female or not a nursing major is the sum of the probabilities of being female and not a nursing major:

P(being female or not being a nursing major) = P(female) + P(not nursing major)

From the table, we have:

P(female) = 2428/3538 ≈ 0.686

P(not nursing major) = 1728/3538 ≈ 0.489

Therefore:

P(being female or not being a nursing major) ≈ 0.686 + 0.489 ≈ 1.175

This probability is greater than 1, which is not possible. Therefore, we need to subtract the probability of being both female and a nursing major (which was counted twice):

P(being female or not being a nursing major) = P(female) + P(not nursing major) - P(female and nursing major)

From the table, we have:

P(female and nursing major) = 700/3538 ≈ 0.198

Therefore:

P(being female or not being a nursing major) ≈ 0.686 + 0.489 - 0.198 ≈ 0.977

Rounded to the nearest thousandth as needed, the probability of being female or not a nursing major is approximately 0.977.

(c) The probability of not being female or a nursing major is the complement of the probability of being female or a nursing major:

P(not being female or being a nursing major) = 1 - P(being female or being nursing major)

From part (a), we have:

P(being male or being nursing major) ≈ 0.574

Therefore:

P(not being female or being a nursing major) ≈ 1 - 0.574 ≈ 0.426

Rounded to the nearest thousandth as needed, the probability of not being female or a nursing major is approximately 0.426.

(d) The events "being male" and "being a nursing major" are not mutually exclusive, because there are 94 males majoring in nursing (as shown in the table). Mutually exclusive events cannot occur at the same time, but being male and a nursing major is a possible combination. Therefore, the correct answer is OB. Yes, because there are 94 males majoring in nursing.

This is the explicit fοrmula fοr this sequence.

An arithmetic series is a set οf integers that are οrdered and have a cοmmοn difference between each fοllοwing wοrd. The cοmmοn difference, fοr instance, between the mathematical series 3, 9, 15, 21, and 27 is 6. An alternative term fοr an arithmetic sequence is an arithmetic prοgressiοn.

The first term is 21 and the cοmmοn difference is -4 (the amοunt added οr subtracted tο get frοm οne term tο the next).

The explicit fοrmula fοr an arithmetic sequence is a n = a + (n - 1)d2, where a is the first term, d is the cοmmοn difference, and n is the term number.

Substituting 21 fοr a and -4 fοr d, we get:

a n = 21 + (n - 1)(-4)

Simplifying, we get:

a n = 21 - 4n + 4

a n = 25 - 4n

1. In the calculation, only one pound of fish food is shared equally among one aquarium.

2. Each of the aquarium gets one pound of fish food

To solve the first part of the problem, we need to find the value of P when 1/2 ÷ 8 = P. By doing the calculation by hand, we get:

1/2 ÷ 8 = 0.0625. So, the  P = 0.0625.

In the second part of the problem, we know that 1 pound of fish is shared equally among a certain number of aquariums, and we need to find that number.

Since each aquarium gets 1 pound of fish food, and the total amount of fish food is 1 pound, we can set up an equation to solve for the number of aquariums:

1 pound of fish food / X number of aquariums = 1 pound of fish food per aquarium

Simplifying the equation, we get:

X = 1 pound of fish food / 1 pound of fish food per aquarium

X = 1 aquarium

Therefore, the pound of fish food is shared equally among 1 aquarium, and each aquarium gets 1 pound of fish food.

Based on the information given in the histogram, option B. The distribution of the data is asymmetrical, so the mean and the median are likely outside the "1,000-1,099 photocopies" category is the correct statement.

What is histogram?

The histogram shows that the distribution of the data is asymmetrical, with a longer tail towards the right. This means that there are more schools that made a higher number of photocopies than those that made a lower number of photocopies. Therefore, the mean and median are likely to be higher than the midpoint of the "1,000-1,099 photocopies" category, which has the highest frequency.

In a skewed distribution, the mean is typically affected by the outliers, while the median is a better measure of central tendency. Therefore, the median is more likely to be within the "1,000-1,099 photocopies" category, while the mean is likely to be higher.

The two given points are (8, 0) and (8, -8).

Using the distance formula, the distance between the two points can be calculated as:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where x1 = 8, y1 = 0, x2 = 8, and y2 = -8

d = sqrt((8 - 8)^2 + (-8 - 0)^2)

d = sqrt(0 + 64)

d = sqrt(64)
