Answer:

  D)  2030

Step-by-step explanation:

You want to know when the population will double from its value in 1995 if it increases at 2% per year.

The multiplier for t years is given as (1 +r)^t. We want to find t such that this value is 2 when r = 0.02.

  2 = 1.02^t

  log(2) = t·log(1.02)

  t = log(2)/log(1.02) ≈ 35.003

The year the population doubles will be ...

  1995 + 35.003 = 2030.003

The population will double in year 2030, choice D.

Rabia is currently classified as unemployed, option .D since she has no job and has declined a job offer.

She falls into the category of frictionally unemployed, which means she is unemployed due to the time it takes to find a job that meets her qualifications and salary needs.

This is different from someone who is cyclically unemployed, which means they are out of work due to economic conditions, or someone who is structurally unemployed, which means they are out of work due to changes in technology or other factors that eliminated their job.

Rabia is still employed in the sense that she is actively seeking employment, but she is not employed in the sense that she has no job.

In the study conducted by John Darley and Bibb Latané, the number of people present in the room with the participant served as an independent variable, as it was manipulated by the researchers to observe its effects on helping behavior.

Specifically, the researchers examined how the presence of other people in the room would affect whether or not the participant would choose to help in a given situation. By changing the number of people present in the room, the researchers were able to measure the effects of diffusion of responsibility on helping behavior.

Diffusion of responsibility is a phenomenon in which individuals are less likely to help a victim when they are in the presence of other people, as they assume that someone else will take responsibility. Therefore, the number of people present in the room was an important variable in the study, as it allowed the researchers to measure how the presence of others affected helping behavior.

Answer:

If you have 3 bags of fertilizer that cover 150 square feet and 2 bags of fertilizer that cover 175 square feet, the total number of square feet that can be covered is:

3 bags x 150 square feet/bag = 450 square feet

2 bags x 175 square feet/bag = 350 square feet

450 square feet + 350 square feet = 800 square feet

So with these total bags of fertilizer, it can cover 800 square feet.

The patient will receive 4875mg

Some drugs, particularly those for children, may be administered based on the individual’s body weight (kg) or body surface area (m2). Simply multiply the dose by the weight to get the needed dose, which can then be used in other formulas. A single dosage of medication containing 2mg/kg is necessary.

The force of gravity pressing down on an item is measured by its weight. It is determined by the mass of the item and the acceleration due to gravity, which is 9.8 m/s2 on Earth. Weight is calculated using the formula F = m 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms. Assume the active substance’s optimal dose is 2 mg/kg of body weight.

Given:

the weight of the patient is: 65kg

he is asked to receive 75 mg/kg of her medicine

therefore, she will have to consume 65*75mg

Answer:

4.21

Step-by-step explanation:

The hundredths place is the second number after the decimal. when rounding, you want to look at the number after. In this case the number after 1 is 0 which is lower than 5. Since it's lower than 5 we will keep the number the same.

Say the number after 1 was 7. Then we would round up and make the 1 into a 2. Any number above 5 you round up and add one to the number. If the number after is below 5, the number doesn't change.

Hope that made sense! :)

Answer:

4.21

Step-by-step explanation:

In this case, the hundredths place is 1 (4.2101, bold number is the hundredths place.) To round it you need to look at the number to the right of it which is 0, and if the number to the right of it is between 0-4 you keep the hundredths place the same and remove any numbers to the right of the hundredths place. Leaving you with 4.21. I hope this makes sense!

Accordingly, 1 ml (milliliter) is just 1/1,000 of a liter. Consequently, 1 ml is less than 1 l.

Small quantities of liquid are measured in milliliters. Liters can be used to measure bigger amounts of liquid. 1 ml is equal to 0.001 liter, or 1000 milliliters. The symbol for a milliliter is either ml or mL.

The metric prefix "m" stands for "milli," which denotes "1/1,000 of" in English. Accordingly, 1 ml (milliliter) is just 1/1,000 of a liter. Consequently, 1 ml is less than 1 l.

The smallest metric unit, the milliliter, measures the tiniest amount of liquid and is a thousandth of a litre. So, 1 liter is equal to 1000 milliliters.

Therefore, the correct answer is option b. 4 liters 300 milliliters < 4,000 milliliters.

The size of a Simple Random Sample (SRS) for estimating the mean score of medical college admissions test takers on your campus depends on the desired level of precision and the variability of the population.

The sample size required to estimate the mean score of a population depends on the desired level of precision, the variability of the population, and the level of confidence desired. In general, a larger sample size is needed to estimate the mean of a population with high variability or when a high level of precision is desired.

On the other hand, a smaller sample size is sufficient if the population is relatively homogeneous or if a lower level of precision is acceptable. It's important to note that a sample size that is too small may result in an imprecise estimate, while a sample size that is too large may be unnecessarily wasteful. A statistician can help determine the appropriate sample size for a given situation.

Answer:

[tex](-1, -2)[/tex]

Step-by-step explanation:

In this problem, we are asked to solve a system of equations given two equations each containing two variables: x and y. We can solve it using the substitution method.

First, we need to solve for a variable in terms of the other using one of the equations. I will solve for x in the first equation.

[tex]4x-7y=10[/tex]

↓ add [tex]7y[/tex] to both sides

[tex]4x=7y+10[/tex]

↓ divide both sides by 4

[tex]x=\dfrac{7y+10}{4}[/tex]

Now that we have solved for x in terms of y, we can substitute the solved x-value into the bottom equation.

[tex]3x + 2y = -7[/tex]

↓ substitute in solved x-value

[tex]3\left(\dfrac{7y+10}{4}\right) + 2y = -7[/tex]

↓ distribute 3

[tex]\dfrac{21y+30}{4}\right) + 2y\left(\dfrac{4}{4}\right) = -7\left(\dfrac{4}{4}\right)[/tex]

↓ rewrite all terms as fractions over 4

[tex]\dfrac{21y+30 + 8y}{4}\right)= -\dfrac{28}{4}[/tex]

↓ cancel denominators

[tex]29y+30= -28[/tex]

↓ isolate y's

[tex]29y = -28 - 30[/tex]

↓ simplify

[tex]29y= -58[/tex]

↓ divide both sides by 29

[tex]y = -2[/tex]

Now that we have solved exactly for y, we can solve for x using the substitution value we solved for earlier.

[tex]x=\dfrac{7y+10}{4}[/tex]

↓ substitute in y-value

[tex]x=\dfrac{7(-2)+10}{4}[/tex]

↓ simplify numerator

[tex]x=\dfrac{-14+10}{4}[/tex]

[tex]x=\dfrac{-4}{4}[/tex]

[tex]x = -1[/tex]

Finally, we can put the solved x and y values into a Cartesian coordinate in the form (x, y).

There are the newspaper has 750 readers.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

If the number of letters to the editor is 60, and it represents 8% of all of the newspaper's readers, we can find the total number of readers by dividing the number of letters by the percentage as a decimal:

60 / 0.08 = 750

Given a quadratic function y = 36 - x² , the intervals over which the function is increasing is: (-∞ , 0) and the intervals over which the function is decreasing is:  (0, ∞).

The standard form of a quadratic function is given by:

f(x) = ax² + bx + c

If a > 0, the graph of the function opens upward and the extreme point is the minimum one.

If a < 0, the graph of the function opens downward and the extreme point is the maximum one.

In this case, the function is: y = 36 - x²

Since the coefficient of the quadratic term is negative, or a < 0, then the graph opens downward and has a maximum point.

y = 36 - x²  is already in the form of perfect square, hence, we can immediately compute:

x-intercepts : (-6,0) and (6,0)

y-(intercept = maximum point = (0, 36)

Before the maximum point, the function is increasing, while after the maximum point, the function is decreasing.

Hence,

increasing interval = (-∞ , 0)

decreasing interval = (0, ∞)
