The compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.
We are given the universal set as:
U = {2, 4, 6, 8, 10, 12, 14, 16}
We are also given that set A is:
A = {6, 10, 14}
We need to find A'
For this, we will subtract set A from the universal set, U.
So, we get that:
A' = U - A
A' = {2, 4, 6, 8, 10, 12, 14, 16} - {6, 10, 14}
Solving the expression, we get that:
A' = {2, 4, 8, 12, 16}
Therefore, we get that, the compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

The table shows the items that come in an appetizer sampler at a family restaurant.
Small Sampler
4 chicken wings
2 loaded potato skins
2 mozzarella sticks
8 pretzel bites
The restaurant wants to create a larger appetizer sampler to accommodate larger groups of customers. They also
want to limit the number of pretzel bites to 20. If the ratio remains the same, how many mozzarella sticks will be in
the larger sampler?
The number of mozzarella sticks that will be in the larger sample will be 5.
How many mozzarella sticks will be in the larger sample?Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s). The sign used to express ratios is :.
The first step is to determine the ratio of mozzarella sticks to pretzel bites in the smaller sample. This can be done by dividing the quantity of mozzarella sticks by the number of pretzel bites.
Number of mozzarella sticks / number of pretzel bites = 2 : 8 or 1 : 4.
Now, divide the number of pretzel bites in the larger sample by the ratio of mozzarella sticks and pretzel bites in the smaller sample.
The ratio of mozzarella sticks in the larger sample = 20 / 4 = 5

The table below shows the masses of some pears in a crate. If one of the pears is chosen at random from the crate, what is the probability that it has a mass of more than 120 g? Give your answer as a fraction in its simplest form.
PLS
The probability that it has a mass of more than 120 g is 13/40.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.
Given,
frequency = 5 9 13 7 6
sum of frequency = 40
P(120<m<=180) = 13/40
P(180<m<=240) = 7/40
P(240<m<=300) = 6/40
Probability that it has a mass of more than 120 g = [P(120<m<=180) + P(180<m<=240) + P(240<m<=300) ]
⇒ 13/40 + 7/40 + 6/40

Use z scores to compare the given values.

In a recent awards ceremony, the age of the winner for best actor was 31 and the age of the winner for best actress was 42. For all best actors, the mean age is 42.4 years and the
standard deviation is 8.2 years. For all best actresses, the mean age is 31.6 years and the standard deviation is 10.3 years. (All ages are determined at the time of the
awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain.
Since the z score for the actor is z= and the z score for the actress is z-, the
had the more extreme age.
So the best actor's age deviates from the mean, he receives the award at the most extreme age.
What is defined as the z score?The z-score of a way of measuring X in a set with mean and standard deviation is given by: z = (x - μ)/σ.The Z-score indicates how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value connected with this z-score. This p-value represents the probability also that measure's value is less than X, or the percentile of X. Subtracting 1 from the p-value yields the probability that measure's value is greater than X.In response to this question:
Whichever z-score does have the highest absolute value, such that, the one that deviates the most from the mean, has a most extreme age.
Best actor: 31 years old, so.
The mean age of the best actors is 42.2 years, with a standard deviation of 8.2 years.
z = (x - μ)/σ
Put the values;
z = (31 - 42.2)/ 8.2
z = -1.36
Best actress:
So, at the age of 42,
The mean of the best actresses is 31.6 years, with a standard deviation of 10.3 years.
z = (x - μ)/σ
Put the values;
z = (42 - 31.6)/10.3
z = 1.01
Thus, Because the best actor's age is further from the mean, he has the most extreme age when receiving the award.

Answer:
14
Step-by-step explanation:
You want the greatest common factor of the terms {98ab^3, 84a, 140b, 112ab}.
Common factorsThere are no variables that are common to all terms. 'a' and 'b' are each common to 3 of the 4 terms, but not all.
The greatest common factor of the constants cannot be larger than the smallest difference of the constants. That difference is ...
98 -84 = 112 -98 = 14
Since 14 is a divisor of all of the constants, 14 is the greatest common factor.

You deposit $3500 in an account that
earns 4% simple interest. How long will
you have to leave the money in the acount
to earn $350 interest?
Answer:
2years 6 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
I = P × R × T/100
Solving our equation:
$350 = $3500 × 4 × T /100
Let's solve your equation step-by-step.
350=(3500)(4)t/100
Step 1: Multiply both sides by 100.
350=(3500)(4)t/100
(350)*(100)=((3500)(4)t/100)*(100)
35000=(3500)(4)t
Step 2: Simplify both sides of the equation.
35000=14000t
Step 3: Flip the equation.
14000t=35000
Step 4: Divide both sides by 14000.
14000t/14000=35000/14000
t=5/2
t = 2.5 years
2.5 years = 2years 6 months

Now,
The sum of the expression 1/3 + 6sqrt5/7 is not rational, even though it is a fraction. A rational number is a number that can be written as the ratio of two integers, such as 1/3 or -4/5. An irrational number is a number that cannot be written as the ratio of two integers, such as sqrt2 or pi.

The area of rectangle at left is 30 cm²The area of rectangle at the bottom of the rectangular prism is 10 cm².The total surface area (TSA) of rectangular prism is 230 cm²
Step-by-step explanation:
Given that
Height = 15 cmWidth = 2 cmLength = 5 cmThe area of the rectangle in front = 15x5 = 75cm²To find
The area of the rectangle on the left side of the rectangular prism.The area of the rectangle at the bottom of the rectangular prismThe total surface area (TSA) of the rectangular prism.So, according to the question
Let's assume,
height = h = 15cm
length = l = 2cm
width = w = 5cm
So, from question,
Area of rectangle in front = 15 cm x 5 cm
That's mean
Rectangle in front have h = 15cm and l = 5cm.
We know the width from question w = 2cm.
So,
Area of the rectangle to the left = h x w
= 15 x 2
= 30 cm²
Also,
There is no height to the rectangle at the bottom.
So, l and w make up the bottom rectangle.
Now,
the area of rectangle at the bottom = l x w
= 5 x 2
= 10 cm²
Now,
The total surface area (TSA) of the rectangular prism = 2(lw + wh + lh)
= 2 ( 75 + 10 + 30)
= 2 x (115)
= 230cm²
So,
