Answer:

16.1157

Step-by-step explanation:

The random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.

A spread measure for a random variable distribution quantifies how much the values of a random variable deviate from the value that is predicted.

For a discrete random variable, the variance is determined by adding the square of the difference between the value of the random variable and the anticipated value, together with the chance that the value of the random variable will occur, across all of the values of the random variable.

It is given that 22 percent of people in the community speak a language other than English at home.

The required number of tries should be represented by the random variable Q.

The geometric distribution of the random variable Q has a p-value of 0.22.

The variance of a random variable is

V(Q) = (1-p)/p²

V(Q) = (1-0.22)/(0.22)²

V(Q) =0.78/0.484

V(Q) =16.1157

Thus, the random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.

Answer: x=8

Step-by-step explanation:

Answer:

The equivalent equation is found by distributing the 1/4 to get 4 + 3x = 28

The first step is subtract 4 to both sides.

The second step is divide both sides by 3.

The answer is x = 8

Answer: y=sin(x)-6

Step-by-step explanation: I guessed and got it right lol

Answer:

5) we get a=6

6) we get c=8

Step-by-step explanation:

The triangles given are similar.

When the triangles are similar, the ratio of corresponding sides are also similar.

5) If c = 12, find a

We will use the ratio

[tex]\frac{30}{12}=\frac{15}{a}[/tex]

Now cross multiply to find value of a

[tex]30*a=12*15\\a=\frac{180}{30}\\a=6\\[/tex]

So, we get a=6

6. If b = 6.4, find c

We will use the ratio

[tex]\frac{30}{c}=\frac{24}{6.4}[/tex]

Now cross multiply to find value of b

[tex]30*6.4=24*c\\c=\frac{192}{24}\\c=8\\[/tex]

So, we get c=8

Answer:

[tex]67^\circ[/tex]

Step-by-step explanation:

Given that:

Initially, Taki has her back to a wall and then starts walking straight forward.

Kindly refer to the diagram attached in the answer area.

Initially, Taki was at point A and then moves towards point B.

At point B, Taki turns [tex]157^\circ[/tex] and then starts walking to reach point C at the wall.

To find:

The angle [tex]x[/tex] that her body is making with the wall.

Solution:

As per question statement:

[tex]M\angle B = 157^\circ[/tex]

We know that angle on straight line is always [tex]180^\circ[/tex]

i.e.

[tex]M\angle B + m\angle B= 180^\circ\\\Rightarrow 157^\circ + m\angle B= 180^\circ\\\Rightarrow m\angle B = 180-157\\\Rightarrow m\angle B = 23^\circ[/tex]

Now, using the angle sum property of a triangle in [tex]\triangle ABC[/tex]:

[tex]m\angle A + m\angle B+ m\angle C = 180^\circ\\\Rightarrow 90+23+x = 180^\circ\\\Rightarrow x = 180 - 90 - 23\\\Rightarrow x = \bold{67^\circ}[/tex]

So, our answer is: [tex]67^\circ[/tex]

Step-by-step explanation:

The y-coordinate of the point where both lines intersect will give us the same solution for x.

At y = 4, both equations will have a corresponding x-value of 1.

Therefore, the value of y that that will make both equations have the same solution of x is 4.

Answer:

<1

Step-by-step explanation:

When an observer is at the same level with the submarine, his line of sight above the horizontal upward to the boat would form an angle called the angle of elevation.

Thus, the angle of elevation from the submarine to the boat is marked as <1. <1 is the angle of elevation from the submarine.

Answer:

Step-by-step explanation:

circumference of a circle = 2 π r

where r = 12.25 cm radius

plugin values into the formula:

circumference of a circle = 2 π (12.25)

                                          = 76.9 cm

The measure of angle x is 129 degrees.

Given that the two parallel lines making angles 51° and x°, these are consecutive angles between the parallel we need to find the measure of x,

So, we know that,

If two lines are parallel, the consecutive interior angles formed by a transversal are supplementary, meaning their measures add up to 180 degrees.

In this case, we have one angle measuring 51 degrees. Let's denote the other angle as x degrees.

Since the angles are consecutive, their measures add up to 180 degrees:

51° + x° = 180°

To find the value of x, we can solve this equation by isolating x:

x° = 180° - 51°

x° = 129°

Therefore, the measure of angle x is 129 degrees.
