The total number of different possible sequences of heads and tails when a coin is flipped 10 times is 1024.

According to the given question.

A coin is flipped 10 times.

As we know that a sample space or sequence is a collection or a set of possible outcomes of a random experiment.

If a coin is flipped once, then the number of possible sequences or outcomes will be 2 (either head or a tail).

Since, the coin is flipped 10 times in a row.

Thereofore,

The number of different possible sequences of heads and tails

= 2^10

= 1024

Where, 2 is the number of possible sequences when a coin is flipped once and 10 is the number of trials.

⇒ 2 × 2 ×2 × 2 × 2 × 2 × 2 × 2 ×2 × 2 = 1024

Hence, the total number of different possible sequences of heads and tails when a coin is flipped 10 times is 1024.

Answer:

jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct

Step-by-step explanation:

so, all angles of a triangle have to add up to 180;

(15x) + (8x - 11) + (3x + 9) = 180

15x + 8x - 11 + 3x + 9 = 180

add your common numbers

26x - 2 = 180

add 2

26x = 182

divide 26

x = 7

put it back into the equation

15(7) + 8(7) - 11 + 3(7) + 9 = 180

180 = 180

The TV repairman charges $40 to come out to your house and check the TV
sergeinik [125]

Answer:

The equation to find the cost of repairing a TV is:

y = 25x + 40

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope or rate of change and b is the y-intercept

Given that the TV chairman charges $40 to come out to your house and check the TV  plus $25 per hour of labor.

It means $40 is the y-intercept because it represents the starting point/condition of the repairman.

Let 'x' be the number of hours and y be the cost.

The rate of change = 25$ per hour of labor

  • The rate of change can also be termed as the slope.

Thus, m = 25

Hence, the slope-intercept form of the line equation becomes

y = mx+b

substituting m = 25 and b=40

y = 25x + 40

Therefore, the equation to find the cost of repairing a TV is:

y = 25x + 40

Validation:

y = 25x + 40

putting x = 1 to determine the cost if labor works for 1 hour.

y = 25(1) + 40 = $65

putting x = 2 to determine the cost if labor works for 2 hours.

y = 25(2) + 40 = $95

Can someone please help ASAP!
Zolol [24]

Pick’s Theorem is used to find the areas of figures on lattices easily. The formula is:

A = (B)/2 + I - 1, where B is the number of points on the border of the shape, and I is the number of points inside the shape.

Here, there are 8 points on the outside of the shape, and there are 12 points inside the shape. So, we do:

8/2 + 12 - 1 = 4 + 12 - 1 = 15 units squared.

We can check by finding the areas of the non-shaded region and subtracting that area from the whole rectangle area of 4 * 10 = 40:

4 * 1 + (3 * 1)/2 + 1 * 9 + (3 * 1)/2 + (9 * 2)/2 = 25

40 - 25 = 15, so we’re right!

The answer is 15 units squared, or choice (B).

What is the equation of a parabola with vertex (0, 0) and directrix x = -3.
miv72 [106K]

Answer:

{y}^{2}= 12x

Step-by-step explanation:

The standard equation of a parabola with vertex at the origin and and directix x=-p is of the form

{y}^{2} =  4{p}x

Where p is simplify the distance from the origin to the directrix.

That is

p =  3

{y}^{2}  = 4 \times 3x

This simplifies to

{y}^{2}= 12x
