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?
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.

In your own words, explain the steps you would need to take to find slope from data in a table.
When I say "your own words" PLEASE DON'T GIVE ME THE SAMPLE RESPONSE ON EDGE
Answer:
For me when I am finding the slope I actually use the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex].
Step-by-step explanation:
Step 1 you have to find the x and y
Step 2: Use the slope formula
Step 3: Subtract y2 and y1 to get your answer
Step 4: Subtract x2 and x1 to get your answer
Step 4: If your answer is easy to divide simplify it, if not leave it as it is
That's all I know
I hope this helps :)
Answer:
Choose two sets of data (x and y values). Calculate the difference between the two y values. Calculate the difference between the corresponding two x values. Slope is the difference in y values / difference in x values.
Hope this Helps!

What is the length of NM?
Answer:
See below :)
Step-by-step explanation:
We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3
[tex]\frac{6}{\sqrt3}[/tex]
We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3
[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]
This then makes it 6 times root 3 over 3
[tex]\frac{6\sqrt3}{3}[/tex]
We then get [tex]2\sqrt{3}[/tex]

A grapefruit weighed 0.65 pound. Which fraction is equivalent to the weight of the
grapefruit in pounds?
Answer:
65/100 pounds
Step-by-step explanation:
P.S Can I have brainliest?
Answer:
13/20
Step-by-step explanation:
Write 0.65 as [tex]\frac{0.65}{1}[/tex]
Multiply both numerator and denominator by 10 for every number after the decimal point
0.65 × 100/1 × 100 = [tex]\frac{65}{100}[/tex]
[tex]\frac{65}{100}[/tex] reduced is 13/20
Twice a number added to another number is 15. The sum of the two numbers is 11. Find the numbers. Write the numbers from least to greatest
Answer:
4 and 7
Step-by-step explanation:
There are probably several ways to do this but this is how I did it:
First, I listed all the number combinations, that added together equaled 11.
This is what it looked like:
1, 10
2, 9
3, 8
4, 7
5, 6
6, 5
7, 4
I stopped here since the next step would be to double the first number and 8*2 would already be more than 15.
Then, I doubled the first number and added the second number to it, when I saw that didn't equal 15, I eliminated that possibility and moved on to the next set of numbers. When I reached 4, 7 I saw that 4*2 equaled 8 and 8 plus 7 equals 15 so I had the answer.
There are probably much more efficient ways to do this but this is how I did it.
Hope it helped!
The first number is 4 and second number is 7.
Let us consider that first number is x and second number is y.
[tex]2x+y=15\\\\x+y=11[/tex]
Substitute [tex]y=11 - x[/tex]in equation [tex]2x+y=15[/tex]
[tex]2x+11-x=15\\\\x=15-11=4[/tex]
So, [tex]y=11-x=11-4=7[/tex]

Which point lies on the circle x^2+y^2=100
A (0,-100)
B (10,-10)
C (25,75)
Answer:
NOT a single ordered pair satisfies the equation.
Step-by-step explanation:
Given the equation
[tex]x^2+y^2=100[/tex]
Let us substitute all the given ordered pairs to find which ordered pair satisfies the equation.
For (0, -100)
[tex]x^2+y^2=100[/tex]
substitute x=0 and y=-100
[tex]0^2+\left(-100\right)^2=100[/tex]
[tex]10000=100[/tex]
FALSE
Thus, the ordered pair (0, -100) does NOT satisfy the equation.
For (10, -10)
[tex]x^2+y^2=100[/tex]
substitute x=10 and y=-10
[tex]10^2+\left(-10\right)^2=100[/tex]
[tex]200=100[/tex]
FALSE
Thus, the ordered pair (10, -10) does NOT satisfy the equation.
For (25, 75)
[tex]x^2+y^2=100[/tex]
substitute x=25 and y=75
[tex]25^2+\left(75\right)^2=100[/tex]
[tex]6250=100[/tex]
FALSE
Thus, the ordered pair (25, 75) does NOT satisfy the equation.
Therefore, NOT a single ordered pair satisfies the equation.
Jane is thirteen years younger than twice Ruby’s age. Nora is 5 years older than Ruby. If their ages sum to 52, find each girl’s age.
Answer:
J=17 N=20 R=15
Step-by-step explanation:
J=Jane
R=Ruby
N=Nora
J=2R-13
N=5+R
J+N+R=52
(2R-13)+(5+R)+R=52
Slove for R and plug into each equation
Answer:
Ruby is 15, Jane is 17 and Nora is 20.
Step-by-step explanation:
Let x represent the age of Ruby.
Jane: 2x - 13
Ruby: x
Nora: x + 5
52 = (x) + (2x - 13) + (x + 5)
52 = x + 2x - 13 + x + 5
52 + 13 - 5 = x + 2x + x
60 = 4x
x = 15
Jane:
2(15) -13
= 17
Nora:
(15) + 5
= 20

Answer:
p=3+4+5=12
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.
