Sabrina has gone to work the last 50 days. On 28 of those days, she arrived before 7:30 A.M. On the rest of the days, she arrived after 7:30 A.M. What is the experimental probability that she will arrive at work before 7:30 A.M. On her next day of work? What is the experimental probability that she will arrive after 7:30 A.M.?

Answers

Answer 1

Answer:

Prob (Arrive before 7.30) =  14 / 25 ; Prob (Arrive after 7.30) = 11 / 25

Step-by-step explanation:

Prob (Arrive before 7.30) = No. of days before 7.30 arrival / Total work days

= 28 / 50  = 14 / 25

Prob (Arrive after 7.30) = No. of days after 7.30 arrival / Total work days

= (50 - 28) / 50 = 22 / 50 = 11 / 25

or , 1 - Prob (Arrive before 7.30) = 1 - 14/25 = (25 - 11) / 25 = 11/ 25

Answers

Answer: x =67

Step-by-step explanation:

The equation to solve this is (x - 22) + 135 = 180

1) To solve for x, you must remove the parenthesis

x - 22 + 135 = 180

2) Simplify the equation...

x - 113 = 180

3) Simplify the equation

180-113 = x

3) Subtract to solve

180 - 113 = x

x = 67

Answer :

As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .

( x - 22 ) + 135 = 180°Remove the brackets

x - 22 + 135 = 180Subtract 22 from 135 and as 135 is is greater than 22 the sign will be positive

x + 113 = 180Subtract 113 from both the sides

x = 180 - 113x = 67°

Thus the correct answer is option d that is x = 67

Answer:

R = 20%

Step-by-step explanation:

Given

I have attached an image to depict this question.

We can see that the point at which the radius goes on the unit circle is a coordinate (x, y)

We are told this coordinate is (0.6, 0.8)

Now, in these type of unit circle diagrams;

x = cos θ and y = sin θ.

Thus;

cos θ = 0.6

cos θ = 6/10

f. Do the segments connecting the coordinates (-1,6), (4,2), and (7,6) form a right triangle? Show
work that leads to your answer.

Answers

Answer:

No, these segments do not form a right triangle.

Step-by-step explanation:

We need to calculate the distances between the points, taking 2 at a time:

From (-1, 6) to (4, 2), x increases by 5 and y decreases by 4.  The distance between the two points, by the Pythagorean Theorem, is d = √(5² + 4²), or √41.

From (-1, 6) to (7, 6) x increases by 8 but y stays the same:  6.  The distance between these two points is therefore 8.

Finally, from (4, 2) to (7, 6), x increases by 3 and y by 4, and so d = 5.

So now we have the 3 side lengths:  √41, 8 and 5.

Squaring them, we get 41, 64 and 25.  These do not satisfy the Pythagorean Theorem:  41 + 25 is not equal to 64.

No, these segments do not form a right triangle.

Write the equation of a line parallel to the line y = 4x - 3 and passing through the point (0,10).

Answers

Answer:

y=4x + 10

Step-by-step explanation:

Parallel lines always have the same slope. The point that you have is the y-intercept because the x is 0. So now you have both the slope and y- intercept and just need to sub it into the y=mx+b equation

The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (0, 10).

And, The parallel line is,

⇒ y = 4x - 3

Now,

Since, The equation of line passes through the point (0, 10).

So, We need to find the slope of the line.

Since, The slope of the parallel line is same.

Hence, Slope of the line is,

y = 4x - 3

m = dy/dx = 4

m = 4

Thus, The equation of line with slope 4 is,

⇒ y - 10 = 4 (x - 0)

⇒ y - 10 = 4x

⇒ y = 4x + 10

Therefore, The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10
