A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again on the second flip?

Question 5 options:

1/4 =0.25=20%

1/4 =0.20=25%

1/2 =0.25=25%

1/4 =0.25=25%

Answers

Answer 1

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

hope that helps

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y=-2x+2

Step-by-step explanation:

Answer:

y = -2x +2

Step-by-step explanation:

y = mx + b

m = slope

y2 - y1/x2 - x1 = m

Using two points, plug in the x values and y values into the equation to find slope.

(0, 2) (1, 0)

2 - 0/0 - 1 = 2/-1 = -2

m = -2

y = -2x + b

b = y-intercept

The y-intercept is the number that crosses through the y axis with an x value of 0.

(0, 2)

b = 2

y = -2x + 2

CAN SOMEONE ANSWER THIS WITH THEIR OWN OPINION Should doctors be allowed to dress casually while at work? Why or why not? What is your opinion?

Answers

I say no, doctors should always come looking professional and ready to work, casual looks will make them blend in with the crowd .
i say no. they should wear their proper attire. if they wore casual clothing at work people and possibly coworkers would think they’re just patients or not an actual worker. this could lead to people that actually need help not coming up to them if it was needed. they should wear their proper attire in case of an emergency or in case they do not want to get their casual clothing dirty in some circumstances.

Dilate this by 1/3

Answers

For this shape there are four points. The plotted ordered pairs are:
M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)

All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.

M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)

(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.

Number of red marbles=4

Number of blue marbles=3

P(B)=3/10

P(R)=4/10=2/5

Total number of marbles=10

Answer:

The number of red marbles is 4. The number of blue marbles is 3. The total number of marbles is 10 because 4+3+3 is 10. P(red) is 2/5 because there are 10 total marbles and there are 4 marbles which is equal to 4/10 marbles are red, and you simplify 4/10 to 2/5. P(blue) is 3/10 because there are 3 blue marbles out of 10 marbles.

Mrs Washington has a greater ratio of band students to chorus students.  I know my answer is correct because I compared the ratio of the band to chorus students where the Band was the same. When Band to chorus had 10:15  students for Washington's class, and Band to chorus had 10:14 in Utley's class. This means That Washington had more students.

Step 1: Simplify both sides of the inequality.

−7x+12≤−2

Step 2: Subtract 12 from both sides.

−7x+12−12≤−2−12

−7x≤−14

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = 4x + 4

Step-by-step explanation:

Two points you can see on the graph are (0,4) and (-2,-4)

Now, to find the slope, use delta y/ delta x

(-4-4)/(-2-0)

(-8)/(-2) = 4

Slope is 4.

y = 4x + b

Now, to find b, we need the y-intercept, which is the point where x is 0 and the graph crosses the y-axis.

This value is 4. So, the y-intercept is 4

Substitute into your equation

y = 4x + 4

Y=4x+4 !!!!!!!!!!!!!!!
