A variable is a characteristic or attribute that can take on different values. It is an observable and measurable property of an object or phenomenon, which can be used to describe and analyze it.

Parameters are used in inferential statistics to make conclusions about a population based on a sample of data.

(a) If you decide to select based on proportion of 10% from each group, the number of patients selected from each group would be: Group A = (10/100) x 100 = 10 patients Group B = (10/100) x 30 = 3 patients Group C = (10/100) x 30 = 3 patients.

(b) The classified groups can be named as follows: Group A = 10 years of education or less Group B = More than 10 years but less than or equal to 20 years of education Group C = More than 20 years of education.

(c) The sampling method employed in the selection process was stratified sampling. Stratified sampling is a type of probability sampling technique where the population is divided into homogeneous subgroups or strata, and the researcher selects a simple random sample from each subgroup or stratum.

The researcher chooses a proportion of participants from each subgroup to represent the population as a whole, which allows for more precise estimates of the population parameters than simple random sampling.

The sample is selected randomly from the stratified sample, which ensures that the sample is representative of the population.

A variable is a characteristic or attribute that can take on different values. It is an observable and measurable property of an object or phenomenon, which can be used to describe and analyze it.

Variables are used in research to test hypotheses, determine relationships between different phenomena, and make predictions about future outcomes.

Answer:

Step-by-step explanation:

Delilah needs to buy 8 reams of paper which cost $5.89 each, $5.89 x 8 = $47.12

Delilah needs to buy 6 cartridges of ink which cost $38.40 each, $38.40 x 6 = $230.4

We then add $230.4 and $47.12

$230.4 + $47.12 = $277.52.

Delilah needs to bring $277.52 to cover the cost of her supplies.

The sky appears blue because of Rayleigh scattering while water appears blue due to selective absorption and scattering of light.

The blue color of the sky is a result of Rayleigh scattering which occurs when the Earth's atmosphere scatters shorter wavelengths of light (blue and violet) more efficiently than longer wavelengths (red and orange).

When sunlight enters the atmosphere, the blue light is scattered in all directions by the molecules and tiny particles present in the air creating the blue appearance of the sky.

Similarly, water appear blue due to selective absorption and scattering of light. Water molecules selectively absorb colors from the visible light spectrum and absorb longer wavelengths (such as red) more effectively than shorter wavelengths (such as blue).

Step-by-step explanation:

The correct answer is (j - k)(x) = 10 + x.

To find the difference in the amount of money between Joel's and Kevin's accounts, we subtract the value of Kevin's account (k(x)) from Joel's account (j(x)).

(j - k)(x) = (25 + 3x) - (15 + 2x)

            = 25 - 15 + 3x - 2x

Answer:

Step-by-step explanation:

Given a game of "rock-paper-scissors" between roommates A and B, you want to know the outcomes and probability associated with A losing, and the outcomes and probability associated with a tie result.

There are 3 choices for each of A and B, so 3×3 = 9 possible outcomes. If event A is roommate A loses, and event C is a tie result, then the 9 possible outcomes will correspond to the events ...

You can see that 3 of the 9 outcomes are associated with event A, 3 are associated with event C, and 3 are neither of events A or C (a wins).

Event A is {(R_A, P_B), (P_A, S_B), (S_A, R_B)}, probability 0.33

Event C is {(R_A, R_B), (P_A, P_B), (S_A, S_B)}, probability 0.33

Answer:

$36,000

Step-by-step explanation:

Given:

Bryce pays $240,000 for a property, then sells it for 15% less of what he bought is for.

To find:

15% of $240,000 to find the total loss.

__

Step 1: Our output value is 240000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,\($240000=100\%$\)

Step 4: Similarly,\($x=15\%$\)

Step 5: This results in a pair of simple equations:

\($240000=100\%(1)$.\)

\($x=15\%(2)$.\)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

\($\frac{240000}{x}=\frac{100\%}{15\%}$\)

Step 7: Again, the reciprocal of both sides gives

\($\frac{x}{240000}=\frac{15}{100}$\)

\($\Rightarrow x=36000$\)

Therefore, \($15\%$ of $240000$ is $36000$\)

So if he lost 15% of $240,000, he lost $36,000.

So now we subtract.

240,000 - 36,000

= $204,000

Hence, the total loss of the property was $36,000

Step-by-step explanation:

To solve the problem we must know about Speed, distance, and Time.

We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,

\(\rm{Speed = \dfrac{Distance}{Time}\)

Given to us

Speed = 60 miles an hour

Don noticed that 3 hours into the trip they were 650 miles from the destination.

We know that Don and Ana are traveling at a constant speed and they are traveling for 3 hours.

\(\rm Distance= \rm speed \times Time\)

\(\rm Distance = 60 \times 3 = 180\rm\ miles\)

Thus, Distance traveled by them in 3 hours is 180 miles.

We know that Don and Ana are traveling on the freeway for the past 3 hours and they are still 650 miles away, therefore,

Total Distance from their destination

= Distance traveled by them in 3 hours + 650 miles

= 180 miles + 650 miles

= 830 miles

Thus, the distance traveled by then is 830 miles.

A.) Distance between them and destination after 3.7 hours since entering the freeway,

Distance traveled by them = speed x 3.7

                                             = 60 x 3.7 = 222 miles

= Total Distance from their destination - Distance traveled by them

= 830 miles - 222 miles

= 608 miles

Thus, they are 608 miles far from their destination.

B.) Distance between them and destination after 2.3 hours since entering the freeway,

Distance traveled by them = speed x 2.3

                                             = 60 x 2.3 = 138 miles

= Total Distance from their destination - Distance traveled by them

= 830 miles - 138 miles

= 692 miles

Thus, they are 692 miles far from their destination.

The amount invested at annual interest of 5% and 8% are $4000 and $10000 respectively.

Simple interest is the cost of borrowing money that does not take compounding into consideration. In other words, just the principal is affected by simple interest. Simple interest is a method of calculating interest that does not take into consideration numerous periods of interest charges or payments. Accrued interest has no bearing on the interest rate; it only applies to the loan or investment's principal amount.

Let us suppose the amount invested in account paying 5% = x.

Let us suppose the amount invested in account paying 8% = y.

The total amount invested is $14000:

x + y = 14000........(1)

The simple interest is given as:

SI = PRT

SI( for 5%) = x(0.05)(1)

SI (for 8%) = y(0.08)(1)

The total interest = SI( for 5%) + SI (for 8%)

Substituting the value:

1000 = 0.05x + 0.08y.......(2)

Equation 1 can be written as:

x = 14000 - y

Substitute the value of x in equation 2:

0.05(14000 - y) + 0.08y = 1000

700 - 0.05y + 0.08y = 1000

700 + 0.03y = 1000

0.03y = 300

y = 10,000

Substitute the value of y in equation 1:

x + y = 14000

x + 10000 = 14000

x = 4000

Hence, the amount invested at 5% and 8% are $4000 and $10000 respectively.
