A random sample of students were chosen from all of 7th grade. There were 3 boys and 5 girls in that sample. If there are a total of 240 students on campus, how many students might be boys?
Answer:
90
Step-by-step explanation:
3 boys
5 girls,
Say that there where "x" number of groups like this, (x will be the total number of groups like this, if one were to divide the population by the number of groups, they would the number of students);
Set up an equation;
x ( 3 + 5 ) = 240
Combine like terms and distribute;
8x = 240
Inverse operations;
8x = 240
/8 /8
x = 30
Substitute back in to find the number of boys;
30 * 3 = 90

You have a standard deck of cards. The deck has 52 total cards and contains 4 suits: hearts, clubs, diamonds, and
spades. Each suit consists of cards numbered 2 - 10, a jack, a queen, a king, and an ace.
You select one card at random from the deck. Let A be the event that the randomly selected card is a club and
let B be the event that the card is a 5. Based on this information, answer the following questions.
What is P(A), the probability that the card is a club?
What is P(B), the probability that the card is a 5?
What is P(A and B), the probability that the card is a club and a 5?
What is P(BA), the conditional probability that the card is a 5 given that it is a club?
Is P(BA) = P(B)? Are the events A and B independent?
Answer:
P(A)=0.25
P(B)=0.077
P(AB)=0.192
P(BA)=0.083
Check below for the full numbers, I rounded it for you.
Step-by-step explanation:
What is P(A), the probability that the card is a club?
So whenever you get a deck of cards you'll have 52 which have 4 suits, think of it like UNO, and club is one of the suit's name! This mean all this question is asking you is the probability of getting a club out of the 52 cards which is
52/4=13
So we know that there is 13 club cards.
Meaning the probability is a 25% since you can only get it 1/4 of the time.
P(A)=0.25
What is P(B), the probability that the card is a 5?
Same as what I stated earlier but this time you only have 4 cards that can be a "5" out of the 52 cards.
4/52=0.076923
P(B)=0.077
What is P(A and B), the probability that the card is a club and a 5?
Keep a eye on the working "and" this means it's referring to the possibility of getting a club and a 5 and since this can only happen once the chances are extremely slim.
1/52=0.1923076
P(AB)=0.192
What is P(BA), the conditional probability that the card is a 5 given that it is a club?
This assumes that you're only drawing from a deck of ONLY clubs so the chances of getting a 5 in that stack.
1/12=0.08333 (3 keeps going)
P(BA)=0.083
(This one might be wrong since I haven't done conditional probability in a long time but I feel somewhat confident, I do feel confident about the rest so no worries.)
Is P(BA) = P(B)? Are the events A and B independent?
No, P(BA) = P(B) is not true since A and B do influence one another since what if I get a 5 without replacement this results in change of chances of A.
Answer:
1.1/4
2.1/13
3.1/52
4.1/13
5. Yes p(B/A)=P(B) and Yes, events A and B are independent events.

Describe how you can tell whether a line’s slope is greater than 1, equal to 1, or less than 1.
Answer:
the slope is determined by rise over run, meaning you first have to see if the line is negative or positive by the direction it is facing,then you have two points that match accordingly to rise over run,to find out you have to see how many boxes(y) you are rising and however many boxes to the right(x) you are running,then you divide rise/run(look in picture attached for more)

Question 3 Evan thinks that the slope of the true line of best fit for Pick Number and Career Length is not zero: that is, there is some correlation/association between Pick Number and Career Length. To test this claim, we can run a hypothesis test! Define the null and alternative hypothesis for this test.
Answer:
Null hypothesis ; H0 : slope = 0
Alternative hypothesis ; H1 : slope ≠ 0
Step-by-step explanation:
Given the claim:
slope of the true line of best fit for Pick Number and Career Length is not zero.
The Null hypothesis H0 : will negate the claim in this scenario ; hence ;
H0 : slope of line of best fit for pick number and career length = 0
The Alternative hypothesis, H1 : is the opposite of the null ;
H1 : slope of line of best fit for pick number and career length ≠ 0

The equation is x + 28 = 224. Then the amount earned by babysitting will be $196.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Nandita earned $224 last month. She earned $28 by selling cards at a craft fair and the rest of the money by babysitting.
Let 'x' be the amount earned by babysitting. Then the equation is given as,
x + $28 = $224
Simplify the equation for 'x', then we have
x + $28 = $224
x = $224 - $28
x = $196
The equation is x + 28 = 224. Then the amount earned by babysitting will be $196.

Answer:
-8
Step-by-step explanation:
Write an equation in slope-intercept form for the line with slope -3 and y-intercept -1. Then graph the line.
Answer:
y=-3x+-1 or y=-3x-1; y intercepts(0,-1); x intercepts(0,1/3)
Step-by-step explanation:
y=mx+b
-1=-3*0+b
-1=0+b
(subtract 0 from both sides)
-1=b
So your equation will be: y=-3x-1
The equation of the line with a slope of -3 and y-intercept of -1 is given as y = -3x - 1. And the graph is shown below.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Write an equation in slope-intercept form for the line with slope -3 and y-intercept -1.
We know that the equation of the line is given as
[tex]\rm y = mx +c[/tex]
Where m is the slope and c is the y-intercept. Then the equation will be
[tex]\rm y = -3x - 1[/tex]
Then the graph of the line is given below.
