A large bakery produces cakes in an assembly line. Sergio noticed a potential defect that seems to be showing in
every other cake. He decides that in the next production run, he'll take a random sample of cakes to get a better
idea of how many cakes might have this defect.
Why might Sergio choose a simple random sample instead of a systematic random sample?

Answers

The system random sampling involves the introduction of a sampling interval during the sampling process. Hence, the use of a fixed interval is more likely to miss the potential defect noticed based on the sampling interval selected.

The systematic random sampling simply involves choosing a fixed sampling interval during the sampling process.

A simple random sampling however selects a truly random sample from a population and this techniques provides the best sample which is representative of the population.

Since a sampling interval is required for a systematic random sample, the sample obtained for different values of k, which is the sampling interval will differ leading to a potential risk of missing the target .

Therefore, with simple random sampling, Sergio stands a better chance of capturing the defect better than using systematic random sampling

Answer:

If the defect is in every other cake, a systematic random sample could miss it completely depending on what Sergio chooses for kkk.

Step-by-step explanation:

Answer:

96  inches2 or 352  cm2

Step-by-step explanation:

-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism. The general formula for the lateral surface area of a right prism is  L.S.A.=ph  where p represents the perimeter of the base and h represents the height of the prism.

Use the point-slope formula below to write an equation of a line passing
through (1, -3) that is parallel to the line y = –2x + 5. Make sure your
final answer is in slope-intercept (y=mx+b) form.

Answers

Step-by-step explanation:

x intercepts = (5/2, 0)

y intercepts = (0,5)

slope = -2

the line y = -2x-5 has a slope of -2 and parallel lines have the same slope

y + 3 = -2( x-1)

y + 3 = -2x + 2

answer: y = -2x -1

Answers

Answer:

The slope is $8 per hour

Step-by-step explanation:

Here, we want to get the slope of the relation

Mathematically, that will be;

m = y2-y1/x2-x1

Where ; (no of hours, money) represents each point

Thus, we have it that

m = (42-10)/(5-1) = 32/4 = $8/ hour

Answers

Answer:

We get value of the value of b = 5

Step-by-step explanation:

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?

We have slope m: [tex]m=-\frac{1}{6}[/tex]

We need to find value of b (y-intercept)

Using the point A(-6,6) and slope [tex]m=-\frac{1}{6}[/tex] we can find b.

Using slope-intercept form, putting values of m and x and y we get the value of b:

[tex]y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5[/tex]

So, we get value of the value of b = 5
