Answer:
The ratios are not equivalent
Step-by-step explanation:
First, in order to find the ratios, we have to change the month to the amount of days.
There are 30 days in April, so we will use this for the ratio.
The ratio for the 3 day weekend is 5:3
The ratio for the month of April is 60:30, which can be simplified to 2:1
So, the ratios are not equivalent, because 5:3 is not equal to 2:1
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.

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)

The side of a square is Two raised to the seven halves power inches. Using the area formula A = s2, determine the area of the square.
Answer:
Step-by-step explanation:
Area of a square = s²
s is the side length of the square
Given
s = 2^{7 1/2}
s = 2^15/2
Area = ( 2^15/2)²
Area = 2^15
Hence two area of the square is 2^15 inches
Answer:
A = 128 square inches
Step-by-step explanation:
A square is a figure with equal length of sides.
Given a square of side, s, [tex]2^{\frac{7}{2} }[/tex] inches.
Area of a square, A = length of side x length of side
= s x s
= [tex]s^{2}[/tex]
Thus,
A = [tex]s^{2}[/tex]
= [tex](2^{\frac{7}{2} } )^{2}[/tex]
= [tex]2^{\frac{14}{2} }[/tex]
= [tex]2^{7}[/tex]
= 128
A = 128 square inches
The are of the square is 128 square inches.

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
