\The graph for the equation y = negative x + 2 is shown below. On a coordinate plane, a line with positive slope goes through (0, 2) and (2, 0). If another equation is graphed so that the system has an infinite number of solutions, which equation could that be? y = negative 2 (x minus 1) y = negative (x + 2) y = negative one-fourth (4 x minus 8) y = negative one-half (x + 4)

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.

?:27

If 4:12 is a ratio of 1:3 then we can assume that the other unknown numbers also use this same ratio. So the ratio for 1:? would be 1:3 and the ratio for ?:27 would be 9:27 bringing you back to the original ratio of 1:3

hello jump in. ok fine abcd

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)

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.

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.

                          28    

                            8

The equation is x + 28 = 224. Then the amount earned by babysitting will be $196.

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.

0.1 mile per min

Step-by-step explanation:

lol i’m fye

The solution is,  her speed was, A) 0.1 mile per minute.

Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Speed = Distance/ Time.

here, we have,

Explanation:

From physics we know that distance, time and speed are related by the following equation:

Speed = Distance/ Time.

So we can write the distance as:

d = s*t

Here we have a line that passes through the origin and whose independent variable is t and dependent variable is d and the slope is s. From the graph, we can calculate the equation of the line as:

y = mx;

where, slope = m = y2 - y1 / x2 - x1

here, (x1, y1 ) = (0,0)

(x2, y2 ) = (10, 1 )

we get, m = 1/ 10

So:

y = x/10

or, y = 0.1 x

As you can see from the graph:

y is related to distance (d)

x is related to time (t)

Therefore, we can rewrite our equation as:

d = 0.1 t

Finally, the speed (s) is:

s = 0.1 per mile

again, we have,

The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:

 (4.5 mi)/(45 min) = 0.1 mi/min

hence, The solution is,  her speed was, A) 0.1 mile per minute.

Answer:

Step-by-step explanation:

Answer:

The perimeter of a rectangle is P = 2 b + 2 h , where is the base (or width) and is the height (or length). If a rectangle is a square, with sides of length , the formula for perimeter is P s q u a r e = 2 s + 2 s = 4 s and the formula for area is A s q u a r e = s ⋅ s = s 2

Step-by-step explanation:

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.
