What is 1 plus 1 minus 2 plus 3

Tim has two spinners , spinnerA and spinner B. Each spinner can only land on red or blue . The probability that spinner A will l

Ganezh [65]

Answer:

52

Step-by-step explanation:

Spinner A

Probability of red = 0.5,
Probability of blue = 0.5

Spinner B

Probability of red = 0.6,
Probability of blue = 0.4

Probability of both A and B land on red:

0.5*0.6= 0.3

Number of attempts to get outcome of 84 red on both spinners is:

84/0.3= 260

Probability of both spinners land on blue:

0.5*0.4= 0.2

Estimated number of both spinners land on blue:

260*0.2= 52

James defines an angle as "a figure consisting of two rays." His statement is not precise enough because he should specify that

riadik2000 [5.3K]

James should define that the rays must be collinear. the two rays coming from the same point will form collinear rays which will form an angle at end point.

The statement of james should be precise in order to clearly explain the angle formation.

The two non collinear rays will form an angle at end point where they meet with each other.

The defined vertex will form the appropriate angle. there should be defined term for the non collinear rays.

An automated teller machine at a local bank is stocked with $10 and $20 bills. When a customer withdraws $40 from the machine, i

cestrela7 [59]

Answer:

There are 4 possibilities

Step-by-step explanation

Each customer has 2 ways to receive the money. For each way, the other customer has 2 option, giving a total of 2*2 = 4. Here are the possibilities, separating in 2 different cases.

Case 1: customer 1 withdraws 2 $20 bills

option 1.1: customer 1 withdraws 2 $20 bills AND customer 2 withdraws 2 $20 bills

option 1.2: customer 1 withdraws 2 $20 bills AND customer 2 withdraws 4 $10 bills

Case 2: customer 1 withdraws 4 $10 bills

option 2.1: customer 1 withdraws 4 $10 bills AND customer 2 withdraws 2 $20 bills

option 2.2: customer 1 withdraws 4 $10 bills AND customer 2 withdraws 4 $10 bills

options 1.1, 1.2, 2.1 and 2.2 give us a total of four ways for the customers to retrieve thier money.

HELP ASAPPP

Sliva [168]

Answer:

Part 1)

The y-intercept is the point (0,-1)

The x-intercept is the point (1/3,0)

The graph in the attached figure N 1

Part 2) The graph in the attached figure N 2 (see the explanation)

Part 3) see the explanation

Step-by-step explanation:

Part 1) Determine the x and y intercepts of the linear equation 3x-y-1=0. Use the intercepts to graph the line

we have

$3x-y-1=0$

step 1

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

$3(0)-y-1=0\\y=-1$

The y-intercept is the point (0,-1)

step 2

Find the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

$3x-(0)-1=0\\x=\frac{1}{3}$

The x-intercept is the point (1/3,0)

step 3

To graph the line, plot the intercepts and join then

The graph in the attached figure N 1

Part 2) Determine the slope and Y intercept of the linear equation 3X minus Y minus one equals zero use the slope and Y intercept to graph the line. On your graph, label the point that represents the Y intercept and one additional point found by applying the slope of the line.

we have

$3x-y-1=0$

isolate the variable y

Adds y both sides

$y=3x-1$

This is the equation of the line in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=3\\b=-1$

so

The y-intercept is the point (0,-1)

Point and a slope to graph the line

the point is (0,-1)

the slope is m=3

Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

rise=3

run=1

so

To graph the line

1. Plot the point (0,-1).

2. From that point, count right 1 unit and up 3 unit and plot a second point.

(0+1,-1+3)

(1,2)

3. Draw a line through the two points

we have

(0,-1) and (1,2)

The graph in the attached figure N 2

Part 3) In the form of a paragraph, compare and contrast the methods used for graphing the linear equation 3x-y-1=0 in Parts 1 and 2

In the first method, we use the intercepts to plot the line (see the explanation part 1)

In the second method, we use the y-intercept and the slope in order to have two points and thus be able to graph the line (see the explanation Part 2)

By comparing and contrasting the two methods, we can see that the graph obtained is the same
