What is the probability of tossing a coin and getting a head 4 times in a row?

Answer:

y = 2x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (3, 6) into the partial equation

6 = 6 + c ⇒ c = 6 - 6 = 0

y = 2x ← equation of line

The equation of line that passes through the point (3,6) with slope 2 is;

⇒ y = 2x

Given that;

The point is (3, 6)

The slope of line = 2

We have to find the equation of a line that passes through the point (3,6) with slope 2.

What is equation of line?

The equation of line that passes through the point (x₁, y₁) with slope m is;

y - y₁ = m (x - x₁)

The point is (3, 6)

The slope of line = 2

The equation of line that passes through the point (x₁, y₁) = (3,6)

with slope(m) = 2 is;

y - y₁ = m (x - x₁)

y - 6 = 2 (x - 3)

y - 6 = 2x - 6

Add 6 on both sides;

y = 2x

Hence, The equation of line that passes through the point (3,6) with slope(m) 2 is;

⇒ y = 2x

Answer:

f(x+3) +7

Step-by-step explanation:

We move the green graph 3 units to the left f(x-h)  where h is how many units moved.  We are moving 3 units to the left so h is -3  f(x - -3)

f(x) becomes f(x+3)

Then we move up 7 units

f(x) +k where k is the number of units up or down

f(x+3) +7

=============================================

Explanation:

For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.

L = 3x

W = x+5

The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.

P = 2(L+W)

2(L+W) = P

2(3x+x+5) = 66

2(4x+5) = 66

8x+10 = 66

8x = 66-10

8x = 56

x = 56/8

x = 7

-------------------

Now that we know x, we can find the area of the rectangles.

As you probably can guess, the shaded region is the difference of the two areas.

A = area of larger rectangle

A = (length)*(width)

A = (3x)*(x+5)

A = (3*7)*(7+5)

A = 252

B = area of smaller rectangle

B = (x+3)*(x+2)

B = (7+3)*(7+2)

B = 90

C = area of shaded region

C = A - B

C = 252 - 90

C = 162 square units is the area of the shaded region.

==========================================================

Explanation:

The table says that when x = 1, the output is y = -2.

So the point (1, -2) is on the parabola.

The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.

Find the slope of the line through those two points. The slope here is the same as the average rate of change.

m = (y2 - y1)/(x2 - x1)

m = (-10 - (-2))/(3 - 1)

m = (-10 + 2)/(3 - 1)

m = -8/2

m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.

Answer:

Mean=85.5

Median=82

Mode=82

Range=25

Please would you mind marking me as the brainliest:)

Answer:

Mean: 85

Median: 82

Mode: 82

Range: 25

Step-by-step explanation:

The mean is the average of all of the numbers. You add all of the numbers together and then divide by the total amount of number you have. In this case you have 8 scores. So you add all the scores together, and then divide by 8:

82 + 78 + 82 + 80 + 100 + 96 + 75 + 91 = 684

684/8 = 85.5

So 85 is the mean.

The median is the number that is in the middle of all of the numbers listed. To do this, first list the numbers in order:

75, 78, 80, 82, 82, 91, 96, 100

The two numbers in the middle are both 82. So, 82 is the median.

The mode is the number that appears the most. In this problem, you can see that the number 82 appears twice. So 82 is the mode.

The range is the highest number minus the smallest number. Here, the highest number is 100. The smallest number is 75. So,

100 - 75 = 25

25 is the range.
