Percentage:
The Latin word "per centum," which meaning "by the hundred," was the source of the English word "percentage." Fractions with a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
What is percentages ?
A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.
Calculation of Percentage:
Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:
By using the unitary method.
By changing the denominator of the fraction to 100.
It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation is not applied. In these situations, we employ the unitary technique.

Zarika earns the same amount each week by walking her neighbor's dogs. When she started this job, she had $300 in her savings account.
The table shows Zarika's savings account balance for her first month of work.
Week 0 1 2 3 4
Balance $300 $550 $800 $1050 $1300
Let x represent the number of weeks Zarika has been working and let y represent Zarika's account balance.
Which equation, expressed in Slope-Intercept Form, represents the amount of money in Zarika's bank account over time?
y=250x+300
y=300x+250
y=300x−250
y=250x−300
Answer:
y=250x+300
Step-by-step explanation:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The amount of money in Zarika's bank account over time after x weeks is represented by the equation.
y = 250x + 300
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
We have,
Amount earned each week = same.
Amount in her account = $300.
Number of weeks = x
Amount in the account = y
The equation represents the account balance after x weeks.
Total amount = $300 + Amount earned per week
This can be written as,
y = 250x + 300
Thus,
The amount of money in Zarika's bank account over time after x weeks is represented by the equation.
y = 250x + 300
Option A is the correct answer.

​(a) The shape of the sampling distribution of the sample mean is approximately normal. Is this true or​ false?
Answer:
Shape of sampling distribution of sample mean being approx normal or not depends upon sample size.
Step-by-step explanation:
'The shape of the sampling distribution of the sample mean is approximately normal' might be true or false, depending on sample size.
If the sample size satisfies the condition of being sufficiently large, the shape of sampling distribution of sample mean becomes more bell shaped normally distributed (even more normally distributed than actual population).
Central Limit theorem also states this - Larger the sample size, shape of sampling distribution of sample mean becomes more normally distributed around population mean.

factor this expression completey -3x - 12
Answer:
-3(x+4)
Step-by-step explanation:
you just factor out -3
Answer: -3(x+4)
Step-by-step explanation:
Hii, do you need to factor -3x-12? No problem!
Note that -3x and -12 have a -3 in common, so we can factor it out by dividing both -3x and -12 by -3.
x+4 (A negative number divided by a negative number gives us a positive result)
Next, we put parentheses around x+4
(x+4)
Now we put -3 outside these parentheses
-3(x+4)
Voila! There's our solution, cheers!

What is proportion?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Now, 3/5 = x/1
⇒ x= 3/5 laps
Here, [tex]1\frac{1}{5} =1.2[/tex]
3/5 = 1.2/y
⇒ 3y=6
⇒ y=2 minutes
3/5 = z/6
⇒ 18=5z
⇒ z=18/5
⇒ z=3.6 laps
Therefore, in 1 minute Victor runs 3/5 laps and in 6 minutes Victor runs 3.6 laps.

Scores on a common final exam are normally distributed with mean 71 and standard deviation 9. Department policy is that the top 10% of students receive an A. The minimum exam score to be awarded an A is about:
Answer:
The minimum exam score to be awarded an A is about 8.52.
Step-by-step explanation:
Let X represent the scores on a common final exam.
It is provided that X follows a normal distribution with mean, μ = 71 and standard deviation, σ = 9.
It is provided that according to the department policy is that the top 10% of students receive an A.
That is, P (X > x) = 0.10.
⇒ P (X < x) = 0.90
⇒ P (Z < z) = 0.90
The corresponding z-score is:
z = 1.28
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\1.28=\frac{x-71}{9}\\\\x=71+(1.28\times 9)\\\\x=82.52[/tex]
Thus, the minimum exam score to be awarded an A is about 8.52.
