Answer:

the answer would be 5.555555 because probability cannot be over one the probability of 0 is 100% never going to happen but the probability of 1 is guaranteed to happen so there for the outcast in this list is 5.55555555

9. Consider the circles with the following equations:

kenny6666 [7]

Answer with Step-by-step explanation:

We are given that

$x^2+y^2=(\sqrt 2)^2$

$(x-3)^2+(y-3)^2=32=(4\sqrt 2)^2$

Compare with the equation of circle

$(x-h)^2+(y-k)^2=r^2$

Where center of circle=(h,k)

r=Radius of circle

a.Center of circle=(0,0)

Radius= $\sqrt 2$ units

Center of second circle=(3,3)

Radius of second circle= $4\sqrt 2$ units

b.Distance formula: $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Using the formula

The distance between the centers of two circle

= $\sqrt{(3-0)^2+(3-0)^2}=3\sqrt 2$

Hence, the distance between the centers of two circle = $3\sqrt 2$ units.

Substitute x=-1 and -1

$1+1=2=$

$(1-3)^2+(1-3)^2=32$

The circle must be tangent because there is just one point (-1,-1) is common in both circles and satisfied the equations of circle.

Andre and Priya are tracking the number of steps they walk. Andre records that he can walk 6000 steps in 50 minutes. Priya write

Bogdan [553]

Let's start by calculating the number of steps Andre walked. He recorded that he can walk 6000 steps in 50 minutes, which means that he can walk 6000/50=120 steps per minute. 5 hours = 5*60 = 300 minutes. So Andre has walked 120 * 300 = 36 000 steps.

Priya writes the equation y=118x in which y is the number of steps and x is the number of minutes. As already stated, 5 hours = 300 minutes. So x = 300. We replace x by its value and we get y = 118x = 118*300 = 35400 steps.

36000>34500 so Andre has walked more steps than Priya.

Hope this helps! :)

The sum of the reciprocals of two consecutive even integers is 3/4 Find the two integers.

Vedmedyk [2.9K]

$\Large{ \underline{ \underline{ \bf{ \orange{Solution:}}}}}$

Let one of those even numbers be x, Then other even number would be x + 2.

According to question,

⇛ Their reciprocal add upto 3/4

So, we can write it as,

⇛ 1/x + 1/x + 2 = 3/4

⇛ x + 2 + x / x(x + 2) = 3/4

⇛ 2x + 2 / x² + 2x = 3/4

Cross multiplying,

⇛ 3(x² + 2x) = 4(2x + 2)

⇛ 3x² + 6x = 8x + 8

⇛ 3x² - 2x - 8 = 0

⇛ 3x² - 6x + 4x - 8 = 0

⇛ 3x(x - 2) + 4(x - 2) = 0

⇛ (3x + 4)(x - 2) = 0

Then, x = -4/3 or 2

☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2

Then, x + 2 = 4

✤ So, The even numbers are 2 and 4.

In the diagram, line I and line m are parallel lines cut by transversal n. b a n m

baherus [9]

The measure of both the interior angles are 70 and 110 degree.

<h3>What are Parallel Lines ?</h3>

Lines they never intersect with each other and the distance between them always remains same are called parallel lines.

It is given that

Line l and m are parallel lines and are intersected by a transversal ,n

Interior angles of the same side are (2x−8) degree and (3x−7) degree

Applying the property of interior angles of parallel lines

2x -8 + 3x - 7 = 180 degree

5x -15 = 180

5x = 195

x = 39 degree

Both the angles have measure of

2 * 39 - 8 = 70 degree

3 * 39 -7 = 110 degree

Therefore the measure of both the angles are 70 and 110 degree.

The complete question is

Two parallel lines l and m are cut by a transversal n . If the interior angles of the same side of n are (2x−8) degree and (3x−7) degree , find the measure of each of these angles.
