Which is the best example of selecting a systematic random sample?
Two distinct groups are formed from members of a population based on some characteristic, and a random
sample of 50 people is selected from each group.
Members of a population are divided into representative groups, and then every 3rd group is selected until a
sample of 100 people is formed.
Members of a population are listed in order of birthday, and every 5th person is selected until a sample of 100

Using it's concept, it is found that the best example of a systematic random sampling is given by:
Members of a population are listed in order of birthday, and every 5th person is selected until a sample of 100 people is formed.
How are samples classified?Samples may be classified as:
Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.In this problem, we want a systematic sample, that is, every kth person(not group), hence the correct option is:
Members of a population are listed in order of birthday, and every 5th person is selected until a sample of 100 people is formed.

Paige only needs to sell to 17 more customers to receive a bonus. She works part time, so she only talks to 50 customers per day. With a sales ratio of 1:9, on which day will Paige qualify for a bonus?
Answers
Answer:
Paige will qualify for a bonus on her 4th day of work.
Step-by-step explanation:
50 customers per day
needs to sell to 17
Ratio = 1:9
1:9
×17 ×17
17:153
Paige needs to see 153 customers.
153 ÷ 50 = 3.06 ≈ 4 (As the answer is not asking for the exact number of the day you round up to make a whole day without underestimating)
So, Paige will qualify for a bonus on her 4th day of work.

shape f !
step-by-step explanation:
hi there!
the question is asking us which shape matches shape a right, now if we look closely we already know that shapes d and b look like they match each other rather then shape a
shape a - 2, 2, 4
so they are out of the equation ( checking how long the sides are )
shape d - 3, 3, 3
shape b - 3, 3, 3
shapes e and c look like they match each other but just to make sure, i counted how long the each side was for both of them
( going by blocks )
shape c - 2, 3, 4,
shape e - 2, 3, almost 5
which does leave us left with shape f, but just to make sure.. lets count it!
shape f - 2, 2, 4,
which is the same numbers that shape a has!
shape f = shape a

If the point (-9,2) is a solution to a linear equation, the point (2,-9) will be a solution to it's inverse. True False
Answers
If the point (-9,2) is a solution to a linear equation, the point (2,-9) will be a solution to it's inverse is false.
If the point (-9,2) is a solution to a linear equation, it means that when you substitute x = -9 and y = 2 into the equation, it satisfies the equation and makes it true.
However, the point (2,-9) will not necessarily be a solution to the inverse of that equation.
To find the inverse of a linear equation, you need to switch the x and y variables and solve for the new y.
So if the original equation is in the form y = mx + b, the inverse will be in the form x = my + b.
Therefore, the point (2,-9) will only be a solution to the inverse equation if substituting x = 2 and y = -9 into the inverse equation makes it true.
It cannot be determined just based on the fact that (-9,2) is a solution to the original equation.

y=x^2 parent functiony=x^2vertex (minimum) at (0, 0); end behavior (-∞, ∞) and (∞, ∞)Step-by-step explanation:
1. You can call the graph whatever you like. Since you're graphing the parent function y=x², you might want that in the title.
__
2. The problem statement tells us we're graphing y = x².
__
3. The quadratic function has one turning point on the axis of symmetry. The turning point for the parent function is its vertex at (0, 0). This point is a minimum, because the parent function has a positive coefficient.
The function is even degree with a positive leading coefficient, so the end behavior tends to +∞ for x going to either -∞ or +∞.
_____
Additional comment
If we're to "refer to the previous slide", it would be nice to be able to see that slide. As is, we're guessing at what the question is really after. The basic y=x^2 function will have been studied first thing when nonlinear polynomials are introduced. This should all be very elementary stuff.

Caroline has a unique pet chimpanzee that is relatively likely to have twins. Each pregnancy is independent, and
Caroline's chimpanzee has a 60% chance of having 1 baby and a 40% chance of having 2 babies each
pregnancy
If X is a random variable that represents the total number of chimpanzee babies if Caroline's chimpanzee gets
pregnant twice, drag the bars to graph the probability distribution for all possible values of X.
Answers
Answer: 2=.36, 3=.48, 4=.16
Step-by-step explanation:
If we let "S" represent 1 baby and "D" represent 2 babies, the sample space for the chimpanzee's 2 pregnancies is {SS, SD, DS, DD}.
We can find the probability of each possible outcome by multiplying the probability of the independent events leading to that outcome.
Outcomes:. Probability:
SS. .60 x .60 = .36
SD. .60 x .40 = .24
DS. .40 x .60 = .24
DD. .40x .40 =.16
Total. 1.00
Lastly group the similar outcomes. SD+DS= .48

The name of the relationship when a function of the form y = abˣ is used to fit the data is, ''Exponential regression''.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
The function is,
⇒ y = abˣ
Now, We know that;
Exponential regression of the equation is of the form,
⇒ y = abˣ
Hence, The name of the relationship when a function of the form y = abˣ is used to fit the data is, ''Exponential regression''.
