choose the correct answer below. a. false. the method for selecting a cluster sample is to order a population in some way and then select members of the population at regular intervals. b. false. the method for selecting a systematic sample is to order a population in some way and then select members of the population at regular intervals. c. true.
The researcher could also use a random number generator to select the members of the sample, instead of selecting them at regular intervals.
The formula for calculating a systematic sample is p = (n/N) x 100, where p is the percentage of the population to be sampled, n is the sample size, and N is the total population size. For example, if a researcher wanted to sample 100 people from a population of 500, the formula would be p = (100/500) x 100 = 20%. This means that the researcher would select every fifth person in the population to be included in the sample. The researcher could also use a random number generator to select the members of the sample, instead of selecting them at regular intervals.

What is the value of x in this triangle?
Answer:
83 degrees
Step-by-step explanation:
Angles inside a triangle is what we called interior angles, which its sum should be equal to 180. Thus, the equation would be like this:
44 + 53 + x = 180
We simply re-arrange the equation to get the value of x.
x = 180 - (44 + 53)
x = 180 - 97
x = 83

What is a combination?In mathematics, a combination or combinations are all the possible groupings that can be made of a given number of elements, without repeating them and regardless of the order in which they are found.
To solve this problem the formula and the combination procedure we must use is:
C(n/r) = n! / [(n-r)! *r!]
Where:
C(n/r) = combination
n = total number of objects
r = number of selected objects
! = factorial of the number
Information about the problem:
n(girl) = 20n(girl) = 1n(boy) = 20n(boy) =1Applying the combination formula we have:
C(n/r) = n! / [(n-r)! *r!]
C(20/1) = 20! / [(20-1)! *1!]
C(20/1) = 20! / [(19)! *1!]
C(20/1) = 20*19! / [(19)! *1!]
C(20/1) = 20/1!
C(20/1) = 20

at Freddy's, three steak burgers zzz and two orders of fries cost $18. Two steak burgers and three orders of fries cost $15.75. What is the cost for one steak burger? What is the cost of one order of feries
The cost of one steak burger is $4.5 and the cost of one order of fries is $2.25.
How to find a cost using equation?To find a cost using an equation, you need to first identify the variables involved in the equation.
Variables are values that can change, such as the price of an item or the quantity of an item. Next, you must determine the value of each variable.
Once you have all the values, plug them into the equation and solve for the cost. For example, if you have an equation where x is the cost, y is the quantity, and z is the price per item, you would plug in the values of y and z and solve for x.
The answer you get would be the cost of the item. Additionally, you can use the equation to find the cost of multiple items by changing the value of the variable y to represent the amount of items you need.
After plugging in the new values into the equation, you can solve for the cost of all the items.
Let x be the fries and y be the steak burgers.
From the following information, the equation are as follows:
2x + 3y = 18 ---------equation 1
3x + 2y = 15.75 -------equation 2
To find cost of one steak burger and cost of one order of fries,
Multiply by 3 in equation 1 and 2 in equation 2,
6x + 9y = 54 -------3
6x + 4y = 31.5 -----4
Subtracting the equation 3 and 4, we get
5y = 22.5
y = 22.5/5
y = 4.5
Substitute y=4.5 in eq 1,
2x + 3(4.5) = 18
2x = 4.5
x = 2.25
∴ The cost of one steak burger is $4.5
∴The cost of one order of fries is $2.25.

Companies A and B provide housekeeping services. The charges are shown in the table. After how many hours will Company A be cheaper than Company B?
After the first 3 hours, Company A will be cheaper than Company B, based on a system of equations.
What is a system of equations?A system of equations or simultaneous equations refers to two or more equations whose solutions are computed concurrently or simultaneously.
Company A Company B
First-hour charge $28 $20
Subsequent half hour $10 $12
Subsequent one-hour $20 $24 ($12 x 2)
Let one hour of housekeeping service after the first-hour charge = x
Company A's total charge for x hours = 28 + 20x ... Equation 1
Company B's total charge for x hours = 20 + 24x ... Equation 2
For the costs to become equal:
28 + 20x = 20 + 24x
-4x = -8
x = 2
For the first 3 hours (2 + 1) of housekeeping service, the costs for both companies are equal.
Thus, after the first 3 hours of service, Company A's charges become cheaper than Company B's.

x = 140 degrees
Step-by-step explanation:
this polygon has 6 sides
to find the number of degrees of the six interior angles you can use this formula:
(n-2)*180 where 'n' equals the number of sides
(6-2)*180 = 4(180) = 720 degrees
starting with the 'x' angle and going clockwise, we have the following:
x + 90 + 104 + 123 + 155 + 108 = 720
x + 580 = 720
x = 720 - 580
x = 140

The interior angles of each regular polygon are 60 degree, 90 degree and 108 degree respectively.
What is interior angle of polygon and how to find?Interior Angle of a polygon = 180° – Exterior angle of a polygon. Method 3: If we know the sum of all the interior angles of a regular polygon, we can obtain the interior angle by dividing the sum by the number of sides. Interior Angle = Sum of the interior angles of a polygon / n.
To solve the given problem, it is necessary to know about the polygon. A polygon is a closed curve that consist a set of line segments connected together, such that there is a no intersection between the segments.
A regular polygon refers to a multi-sided convex figure where all the sides are equal in length and all the angles have equal degree measures.

A placebo is a medication or procedure that is given to a patient for psychological rather than physiological reasons.
The most typical sources of caffeine in nature are the cocoa, tea, and coffee plants. It functions by activating the central nervous system and brain, keeping you alert and delaying the development of fatigue.
Coffee has a maximum of 86 mg of caffeine per serving.
The highest daily dose of caffeine recommended by health authorities, excluding those who are pregnant or breastfeeding, is 400 mg for healthy individuals. Additionally, it is advised to consume no more than 200 mg of caffeine daily from all sources while pregnant or nursing.
Unwanted adverse effects might arise from placebos. Negative placebo effects, often referred to as nocebo effects, have been documented as nausea, drowsiness, and allergic reactions, including skin rashes.

Answer:
the interest rate required in order for Josiah to end up with $5,400, assuming the interest is compounded daily, is 10.3%
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^nt
Where:
A = the amount of money in the account after the interest has been added
P = the initial investment (principal) of $4,800
r = the annual interest rate (expressed as a decimal)
n = the number of times the interest is compounded per year
t = the number of years the money is left in the account
We know that A = $5,400 and t = 6 years, so we can substitute these values into the formula:
5400 = 4800(1 + r/n)^(6n)
To find the interest rate, we need to solve for r.
we know that the interest is compounded daily, so we will use n = 365
5400 = 4800(1 + r/365)^(6*365)
To find the interest rate, we need to solve for r, we can use a calculator to find the value of r.
r ≈ 0.103 or 10.3% to the nearest tenth of a percent
So, the interest rate required in order for Josiah to end up with $5,400, assuming the interest is compounded daily, is 10.3%

In this case, the medical study reported that people who owned pets had lower blood pressure than those who did not own pets. This led some doctors to believe that pet ownership had positive health benefits. However, further analysis of the data revealed that the pet owners in the study also exercised more and smoked less than those who did not own pets.
