Answer:
A. 6
Step-by-step explanation:
The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.
AB = 6
_____
Additional comment
"A and B" is also called the "intersection" of the two sets: A ∩ B.
The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A or B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)
Find the equation of the line that is perpendicular to y = 2x + 4 and passes though the point (2,-2).
A)
B)
y=-x-1
y - 2x + 1
D)
y = -2x + 1
Perpendicular lines have slopes that are negative reciprocals of each other, so since the slope of the given line is 2, the slope of the line we want to find is -1/2.
Substituting into point-slope form,
[tex]y+2=-\frac{1}{2}(x-2)\\\\y+2=-\frac{1}{2}x+1\\\\\boxed{y=-\frac{1}{2}x-1}[/tex]

A group of people move a large box that weighs 90 Newtons, 10 meters in 20 seconds, how much power was used?
Answer:
P = 45 W
Step-by-step explanation:
Given that,
The weight of a box, W = 90 N
Distance moved, d = 10 m
Time, t = 20 s
We need to find the amount of power used. The rate of doing work is called power It can be calculated as the formula,
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{90\times 10}{20}\\\\P=45\ W[/tex]
So, 45 W of power was used.
1219 kg of Swiss cheese is packaged in 3 kg bags. Will there be any cheese left over? How do you know?
Answer:
1 cheese is left over.
Step-by-step explanation:
Given that,
1219 kg of Swiss cheese is packaged in 3 kg bags.
i.e. 3 kg bags = 1219 kg of Swiss cheese
Implies, 1 kg bag = [tex]\dfrac{1219}{3}[/tex] kg of swiss cheese
If we divide 1219 by 3, we get [tex]46\dfrac{1}{3}[/tex]. Here, 46 is the quotient and 1 is the remainder.
It means 1 cheese is left over.
Someone please answer this correctly!!
Answer:
1.98 × 10^10
Step-by-step explanation:
First solve for how many text messages were sent out per one month:
22,000,000 × 900
19,800,000,000
Convert into scientific notation:
1.98 × 10^10
In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.

Answer:
b. 255.5 to 499.5
Step-by-step explanation:
The middle 50% is the range between the first and third quartiles. In this group of 9 numbers, the first quartile is the average of numbers 2 and 3 when the numbers are listed from smallest to largest.
first quartile = (230 +281)/2 = 255.5 . . . . . . matches answer choice B
The third quartile is the average of numbers 7 and 8:
third quartile = (468 +531)/2 = 499.5 . . . . . also matches answer choice B
The middle 50% is 255.5 to 499.5.
_____
When I put the numbers in order, I get ...
198 230 ^ 281 246 376 426 468 ^ 531 540

Andre and Molly have a tree fort that consists of two rectangular rooms,
The upper level has a length of 5 feet, a width of 3 feet, and a helght
of 6 feet. The lower level has a length of 6 feet, a width of 5 feet, and a
height of 8 feet.
What is the combined volume of the two levels of the tree fort?
33 cubic feet
150 cubic feet
240 cubic feet
330 cubic feet
Help!
Answer:
330 cubic feet
Step-by-step explanation:
The formula for Volume is L (length) x W (width) x H (Hight)
So all we have to do is multiply the numbers for each floor and then add them together.
5 x 3 = 15 15 x 6 = 90
6 x 5 = 30 30 x 8 = 240
240 + 90 = 330
Now add you cubic feet since volume is cubed.
330 cubed feet
Thus, your answer is 330 cubed feet.

If y = 8(2. 4)* represents the number of bacteria in a culture at time t, how
many will there be at time t =9 ?
Answer:
21134 bacteria
Step-by-step explanation:
The given parametrs can be interpreted as:
[tex]y = 8(2.4)^t[/tex]
Required
Find y when t = 9
Substitute [tex]t = 9[/tex]
So:
[tex]y = 8(2.4)^9[/tex]
[tex]y = 8 * 2.4^9[/tex]
[tex]y = 8 * 2641.81[/tex]
[tex]y = 21134.48[/tex]
[tex]y = 21134[/tex] --- approximated

A trade school would like to measure the long-term success of their graduates after they leave the school. The school emais a survey requesting information from graduates about their work experience. One question asks graduates to share their annual salary, and the results of the question will be shared in a brochure for incoming
students. Is it likely that the survey results will provide an accurate estimate of mean annual salary for all of the
school's graduates?
The survey will provide a reasonable estimate of mean annual salary because all graduates were sent the email
survey
The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey
The survey will likely underestimate mean annual salary because there may be more graduates with lower
salanes than higher salaries
The survey will likely overestimate the mean annual salary because the email was only sent to graduates with jobs in their chosen feld
Answer: The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey.
Step-by-step explanation:
We should note that this is voluntary response because despite the fact that the email was sent to the students, a graduate can decide to be part of the sample or not.
In this case, those that have higher salaries will be more likely to respond to their emails than those that have lower salaries. Therefore, the survey will likely overestimate mean annual salary.
A new bank customer with $5,000 wants to open a money market account. The bank is offering a
simple interest rate of 1.5%.
a. How much interest will the customer earn in 30 years?
b. What will the account balance be after 30 years?
Answer:
Amount of interest in 30 year = $2,250
Account balance after 30 year = $7,250
Step-by-step explanation:
Given:
Amount deposit P = $5,000
Simple interest rate = 1.5% = 0.015
Find:
Amount of interest in 30 year
Account balance after 30 year
Computation:
Interest = PRT
Amount of interest in 30 year = (5,000)(0.015)(30)
Amount of interest in 30 year = $2,250
Account balance after 30 year = P + I
Account balance after 30 year = $5,000 + $2,250
Account balance after 30 year = $7,250

Answer:
monthly payment $690.25total interest $123,490total repaid $248.490difference from rent $9.75Step-by-step explanation:
Frank's monthly payment will be $690.25.
The total of all payments will be $690.25 × 360 = $248,490.00.
The interest Frank will pay is $248,490 -125,000 = $123,490.00.
The difference between Frank's rent and his loan payment is ...
$700 -690.25 = $9.75
Find P (Horse Female) Hint: P(A and B)

Chicken 2

Piel 5
=========================================================
Explanation:
The vertical bar means "given", so saying "P(Horse | Female)" means "The probability of selecting a horse given the animal is female". Since we know the animal is female, we focus only on the second column.
There are 2 female horses out of 26 female animals total. Therefore, the probability we want is 2/26 = 1/13
Side note: The hint your teacher provides is also another route you can take, but I find it's a bit more complicated in my opinion.
P (Horse | Female) = 1/13
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
What is conditional probability?"It is the probability of an event occurring given that another event has already occurred."
Formula for conditional probability:The probability of event A occurring given that event B has already occurred is,
P(A|B) = P(A ∩ B)/P(B)
where, P(A ∩ B) the joint probability of events A and B
For given example,
We need to find P (Horse | Female)
From given table we can observe that there are 40 animals on farm.
⇒ n(S) = 40
First we find the probability of female animals on farm.
⇒ number of female animals = 26
Using the formula of probability,
⇒ P(Female) = n(Female)/n(S)
⇒ P(Female) = 26/40
First we find the probability of female horse [P(Horse and Female)] animals on farm.
⇒ n(Horse and Female) = 2
Using the formula of probability,
⇒ P(Horse and Female) = n(Horse and Female) / n(S)
⇒ P(Horse and Female) = 2/40
Using the formula of conditional probability,
⇒ P (Horse | Female) = P (Horse and Female) / P(Female)
⇒ P (Horse | Female) = (2/40) / (26/40)
⇒ P (Horse | Female) = 2/26
⇒ P (Horse | Female) = 1/13
Therefore, P (Horse | Female) = 1/13
