Probability sampling procedures are instances where every unit in the population has a non-zero chance of being selected. (Option a)
Probability sampling is a type of sampling method used in statistical analysis, where each member of the population has a known and equal probability of being selected. This means that every possible unit in the population has a non-zero chance of being selected for the sample.
Probability sampling methods include simple random sampling, systematic sampling, stratified sampling, and cluster sampling. These methods are typically used when population parameters are unknown or when the researcher wants to make generalizations about the population based on the sample data.

Carol shares a joke with 3 of her friends. The next day, each of her friends tell the joke to 4 other people. The next day, each people that heard the joke the previous day tells the joke to four different people. The expression 3(4^(x)) models this situation where x represents the number of days after Carol initally told the joke. What do the different parts of the expression represent?
Answer:
Step-by-step explanation:
In this expression, the number 3 represents the initial group of friends to whom Carol told the joke.
The base number 4 represents the number of people each friend told the joke to on the following day.
The exponent x represents the number of days that have passed since Carol first told the joke, and as a result, the number of "generations" of people who have heard the joke.
Therefore, 4 raised to the power of x represents the total number of people who have heard the joke after x days, including Carol's initial group of friends and all subsequent generations of people who have been told the joke by those who heard it before.
Finally, multiplying 3 and 4 raised to the power of x gives the total number of unique people who have heard the joke after x days, since the initial group of friends is not included in the later generations.

The closest value to the standard deviation of the 100 times is (C) 20 seconds.
To determine the closest value to the standard deviation of the 100 times, we would need the actual histogram or the data points themselves.
In general, the standard deviation measures the spread or dispersion of a set of values. A higher standard deviation indicates a greater dispersion, while a lower standard deviation indicates a smaller dispersion.
Looking at the given options, (A) 2.5 seconds and (B) 10 seconds are relatively small values, which suggests a low dispersion among the times. On the other hand, options (D) 50 seconds and (E) 90 seconds are larger values, indicating a higher dispersion.
Option (C) 20 seconds falls in between the smaller and larger values. While it is difficult to determine the exact standard deviation without the data, option (C) of 20 seconds seems like a reasonable choice as it represents a moderate spread among the 100 times.

13.4 square inches of plastic wrap will be needed to completely cover an ice cream cone that has a slant height of 4.25 inches and a diameter of 2 inches.
To completely cover an ice cream cone that has the slant height of 4.25 inches and a diameter of 2 inches, a plastic wrap of about 13.4 square inches will be needed.
How to calculate the amount of plastic wrap required to cover the ice cream cone?
To calculate the amount of plastic wrap required to cover the ice cream cone, we need to find the lateral area of the cone. This can be calculated using the following formula:
Lateral area of cone = πrℓ
where r is the radius of the base of the cone, ℓ is the slant height, and π is the constant pi, which is approximately equal to 3.14.
In this problem, the diameter of the cone is given as 2 inches, which means the radius of the cone will be half of that, i.e., 1 inch. And the slant height is given as 4.25 inches. Therefore, we can calculate the lateral area of the cone as follows: Lateral area of cone = πrℓ = π × 1 × 4.25= 13.4 square inches.

after a (not very successful) trick or treating round, candice has 12 tootsie rolls and 10 twizzlers in her pillow case. her mother asks her to share the loot with her three younger brothers. (a) how many different ways can she do this?
Using the stars and bars technique, Candice can distribute her 24 pieces of candy among her four siblings in 2,925 different ways. If she must give each sibling at least one of each type of candy, there are 67,200 ways to distribute the candy among the four siblings.
(A) To solve this problem, we can use the technique of stars and bars. We have a total of 24 pieces of candy to share among four children. We can represent this using 24 stars, with 3 bars to separate the stars into four groups, one for each child. For example, the following arrangement represents giving 6 pieces of candy to the first child, 10 pieces to the second child, 3 pieces to the third child, and 5 pieces to the fourth child:
*****|**********|***|****
The number of ways to arrange the stars and bars is equal to the number of ways to choose 3 positions out of the 27 possible positions for the stars and bars. Therefore, the number of different ways that Candice can share her candy with her three younger brothers is:
C(27, 3) = 27! / (3! * 24!) = 2925
(B) Now, we need to ensure that each child receives at least one Tootsie roll and one Twizzler. We can give each child one of each candy to start, and then distribute the remaining 13 Tootsie rolls and 7 Twizzlers using the stars and bars technique. We have 13 Tootsie rolls and 7 Twizzlers to distribute among four children, which can be represented using 13 stars and 3 bars for the Tootsie rolls, and 7 stars and 3 bars for the Twizzlers. The number of ways to arrange the stars and bars for each type of candy is:
C(16, 3) = 560 for the Tootsie rolls
C(10, 3) = 120 for the Twizzlers
To find the total number of ways to distribute the candy, we can multiply the number of ways for each type of candy:
560 * 120 = 67200
Therefore, there are 67,200 different ways for Candice to share her candy with her three younger brothers after her mother asks her to give at least one of each type of candies to each of her brothers.

you work as a cashier in a supermarket. on saturday, you had 135 customers. on sunday, you had 90 customers. what is the approximate percent decrease
The approximate percent decrease in the number of customers from Saturday to Sunday is 33%. Therefore, the answer is option A: 33%
To find the approximate percent decrease in the number of customers from Saturday to Sunday, we first need to calculate the decrease in the number of customers:
Decrease = Saturday customers - Sunday customers
Decrease = 135 - 90
Decrease = 45
The percent decrease can be found by taking the decrease as a percentage of the original value (Saturday customers):
Percent decrease = (Decrease / Saturday customers) x 100%
Percent decrease = (45 / 135) x 100%
Percent decrease = 33.33%
Rounding to the nearest percent, we get that the approximate percent decrease in the number of customers from Saturday to Sunday is 33%. Therefore, the answer is option A: 33%.

What is the recursive formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
For instance: An arithmetic series has the recursive formula a = an-1 + d.
An = An-1r is the recursive formula for a geometric sequence.
Because each phrase, an, goes back to the preceding term, an1, the formula an=2an1+3 is recursive.
According to this equation, any term we want is equal to two times the previous term plus three.
This sequence's first three terms are 4, 11, and 25.
So, we have the sequence:
-44, -46,-48, ...
Now, we have d that is:
= -48 - (-46)

(be sure to round up; you can't survey part of a person)
Jennifer needs to sample at least 151 vets to achieve a standard error of the mean of 3.42 years or less.
The variability or uncertainty of a sample statistic, like the mean or proportion, is measured by standard error. It represents the sample distribution's standard deviation for that statistic. In other words, it calculates the amount by which chance is likely to cause the sample statistic to deviate from the actual population parameter.
The calculation of the standard error is based on the particular statistic being produced as well as the characteristics of the sampled population. For instance, the population's standard deviation is divided by the square root of the sample size to determine the standard error of the mean. If p is the estimated proportion based on the sample, then the standard error of a proportion is determined as (p * (1 - p)) divided by the square root of the sample size.
A population parameter estimate that has a lower standard error is more accurate. Inferential statistics frequently employ the standard error to compute confidence intervals and test population parameter-related hypotheses.
The formula for the standard error of the mean can be used to get the approximate number of veterans Jennifer needs to sample:

where n: sample size, delta: age standard deviation, and SE: standard error of the mean.
In this instance, we are aware that = 22 years and SE = 3.42 years. As we solve for n, we obtain:
[tex]n = (delta / SE)^2 n = (22 / 3.42)^2 \sn = 150.39[/tex]

How much more expensive is it, per pound, to buy chicken thighs at Store B than at Store A?
Answer:
To find out how much more expensive it is, per pound, to buy chicken thighs at Store B than at Store A, we need to compare the cost per pound at each store.
At SuperGrocery B, we know that 3 pounds of chicken thighs cost $34.80, so the cost per pound is:
$34.80 / 3 pounds = $11.60 per pound
At SuperGrocery A, we can use the information in the table to find the cost per pound for each amount of chicken thighs:
For 1.5 pounds of chicken thighs:
$13.52 / 1.5 pounds = $9.01 per pound
For 3 pounds of chicken thighs:
$27.03 / 3 pounds = $9.01 per pound
For 3.5 pounds of chicken thighs:
$31.54 / 3.5 pounds = $9.01 per pound
For 4.5 pounds of chicken thighs:
$40.55 / 4.5 pounds = $9.01 per pound
So the cost per pound of chicken thighs at SuperGrocery A is $9.01 per pound, which is less expensive than the cost per pound at SuperGrocery B, which is $11.60 per pound.
To find the difference between the two prices, we can subtract the cost per pound at SuperGrocery A from the cost per pound at SuperGrocery B:
$11.60 per pound - $9.01 per pound = $2.59 per pound
Therefore, it is $2.59 more expensive, per pound, to buy chicken thighs at SuperGrocery B than at SuperGrocery A.
Write the slope-intercept form of the equation of the line described.
through: (-4, -1), parallel to y =
-1/2x-2
Answer:
y = - [tex]\frac{1}{2}[/tex] x - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{2}[/tex] x - 2 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
• Parallel lines have equal slopes , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
to find c substitute (- 4, - 1 ) into the partial equation
- 1 = - [tex]\frac{1}{2}[/tex] (- 4) + c = 2 + c ( subtract 2 from both sides )
- 3 = c
y = - [tex]\frac{1}{2}[/tex] x - 3 ← equation of parallel line
Which equation has the same solution as x ^2 −12x−16=−2?
