Answer:
a) A simple random sample of 340 employees
b) a) Cluster sample
Step-by-step explanation:
a) Remember, the sample size of most research work is a factor to consider in other to determine if the data collected represents the true percentage of the entire population.
Hence, a small random sample of 34 employees will not give more precise information than a larger sample of 340 employees because the larger sample contains more representation of the population.
b) A cluster sample is best used in this case because it involves dividing the population into several clusters or groups, then the researcher randomly selects a particular cluster or group in other collect research data for analysis.
Whereas in this case, the randomly selected clusters are the different (individual restaurant) franchise locations.
What is the measure of angle x?

Enter your answer in the box
82
m3 =
Answer:
61
Step-by-step explanation:
we kno that a triangle is 180 degrees so we just add the first two angles
37 + 82 = 119
then subtract that from 180
180 - 119 = 61
so x = 61 degrees

Mauricio scored a total of 34.42 points in five gymnastic
events. Which number sentence shows the best way to
estimate Mauricio's score for each event?
(a) 35 = 5 = 7
(b) 35 - 7 = 5
(C) 30 = 10 = 3
(d) 40 = 10 = 4
Answer choice:
Explain how you chose your answer.
Answer:
Mauricio's score for each event is 7.
Step-by-step explanation:
Mauricio scored a total of 34.42 points in five gymnastic events.
We can round off his score as 35.
To find Mauricio's score for each event, divide total score and no of events as follows :
[tex]n=\dfrac{35}{5}\\\\=7[/tex]
Hence, Mauricio's score for each event is 7.
6 x (12 - 7)
Thanks for answering!
Answer:
30
Step-by-step explanation:
since 12 - 7 is in the- um- whatever these- ( )- things are called (I forgot), you do it first. 12 - 7 is 5.
Next you do 6 x 5 which gives you your final answer of 30.

Answer:
2x² + 9x - 5
Step-by-step explanation:
Given
(2x - 1)(x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 5) - 1(x + 5) ← distribute both parenthesis
= 2x² + 10x - x - 5 ← collect like terms

A line passes through the points (-4, 0) and (1, 10). What is its
equation in slope-intercept form?
Answer:
The answer is y=2x+8
Step-by-step explanation:
(-4,0)&(1,10)
m=y²-y¹/x²-x¹
m=10-0/1-(-4)
m=10÷5
m=2
y-y=m(x-x¹)
y-10=2(x-1)
y-10=2x-2

Compare the scores: a score of 75 on a test with a mean of 65 and a standard deviation of 8 and a score of 75 on a test with a mean of 70 and a standard deviation of 4.
Answer:
The Zscore for both test is the same
Step-by-step explanation:
Given that :
TEST 1:
score (x) = 75
Mean (m) = 65
Standard deviation (s) = 8
TEST 2:
score (x) = 75
Mean (m) = 70
Standard deviation (s) = 4
USING the relation to obtain the standardized score :
Zscore = (x - m) / s
TEST 1:
Zscore = (75 - 65) / 8
Zscore = 10/8
Zscore = 1.25
TEST 2:
Zscore = (75 - 70) / 4
Zscore = 5/4
Zscore = 1.25
The standardized score for both test is the same.

find the measure of the line segment RQ
===========================================
Work Shown:
RS*QS = (TS)^2
RS*(QR+RS) = (TS)^2
27*(5x-12+27) = (45)^2
27*(5x+15) = 2025
135x+405 = 2025
135x = 2025-405
135x = 1620
x = 1620/135
x = 12
Use this to find the length of QR, which is the same as RQ
QR = 5x-12
QR = 5*12-12
QR = 60-12
QR = 48

Group of answer choices
potential to kinetic
kinetic potential
thermal to kinetic
kinetic to thermal
Answer: potential to kinetic
Step-by-step explanation:
Answer:
Kinetic Energy is defined as energy that a body possesses by virtue of being in motion.
Kinetic Energy is defined as energy that a body possesses by virtue of being in motion.As you walk down stairs, as water boils, and as the planets orbit the sun, kinetic energy is being utilized.GRAVITATIONALApple falls from tree and rolls behind the trunk.
GRAVITATIONALApple falls from tree and rolls behind the trunk.An object’s relative location to a gravitational field is the gravitational potential an object has to do work.

NUCLEARElectrons circle a nucleus at the atomic level.The mass of an atom’s nucleus is almost entirely comprised of its protons and neutrons. The force binding them together is considered potential energy because it causes them to weigh less than the sum of their parts.ELASTICSpring animation expands and compresses.
ELASTICSpring animation expands and compresses.Elastic potential energy is present when the object, such as a spring, is in a deformed state but can return to a static state. This means the spring has elastic potential energy when it is either stretched or compressed.CHEMICALBattery animation motions towards a full charge.
CHEMICALBattery animation motions towards a full charge.Every animate and inanimate object is the result of chemical reactions. Chemicals in a battery have the potential to be converted into motion, therefore they have chemical potential energy.Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.When you (or a rock) are standing at the top of a hill, you possess more potential energy than when standing at the bottom. This is because your position relative to the Earth’s center of gravity can exert potential energy upon you to bring you closer to that center.Energy can neither be created nor destroyed, this is the conservation of energy law. However, energy can be altered from one form to another.

Mathematically:
3 to 6 and 4 to x
Represent as a ratio:

Convert to fraction
[tex]\frac{3}{6} = \frac{4}{x}[/tex]
Cross Multiply:
[tex]3 * x = 6 * 4[/tex]

Meryl needs to cut down 10.5 trees for every 555 cabins she builds.
Answer:
6.3 trees.
Step-by-step explanation:
We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.
Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.
Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.

Represent the division expression using unit form.
Answer:
I think the question you are trying to say is . . . A baker bought some flower. He used 2/5 of the flour to make bread and used the rest to make batches of muffins. If he used 16lb of flour making bread and 2/3 lb for each batch of muffins, how many batches of muffins did he make?
So I have provided the answer and explanation below.
Step-by-step explanation:
He make 36 batches of muffins.
Consider the provided information.
It is given that he used 2/5 of the flour for bread, and he used 16lbs for bread.
Let total amount of flour is x lbs, now convert above statement into mathematical form.
2/5 x = 16
2x/5 = 16
x = 5 • 16/2 = 80/2
x = 40
Therefore, he bought 40 lbs of flour.
He used 16 lb out of 40.
So for muffins he left with 40-16=24 lbs of flour.
It is given that he used 2/3 lb. For each batch of muffins.
Divide 24 with 2/3 lb.
24/2/3 = 24 • 3/2
72/2 = 36
Hence, he make 36 batches of muffins.

Answer:
k = 5
Step-by-step explanation:
First, add 3 to both sides;

Divide by 7:
[tex]\frac{7}{7}k = \frac{35}{7}\\k = 5[/tex]
Now, let's check our answer:
[tex]7(5) - 3 = 32\\35 - 3 = 32\\32 = 32[/tex]
