Answer:

The value is  [tex]P(X \le 22) = 0.2[/tex]

Step-by-step explanation:

From the question we are told that

   The lower limit of the interval is  [tex]a = 20[/tex]

    The upper limit of the interval is  [tex]b = 30[/tex]

Generally the cumulative distribution function for uniform distribution is mathematically represented as  

   [tex]F(x) = \left \{ {{0 \ \ \ \ \ \ \ \ \ \ \ for x < a } \atop {\frac{x - a}{b-a} \ \ \ \ \ \ for  a \le x \le b }} \atop { 1 \ \ \ \ \ \ \ \ \ \ \  for  x >  b}\right.[/tex]

Generally  the probability that an oil change job is completed in less than or equal to 22 minutes is mathematically represented as

              [tex]P(X \le 22) = \frac{22 - 20}{30 - 20 }[/tex]

=>          [tex]P(X \le 22) = 0.2[/tex]

Answer:

5

Step-by-step explanation:

a+b=30

a=30-b------1

&a-b=20

a=20+b-----2

From eqn 1 and 2, we get

30-b=20+b

or, 10=2b

b=5

Now, a=20+5

a=25

Therefore, a/b=25/5

=5

Using a system of equation, the value of a/b obtained from the values of a and b calculated is 5

The system of equations:

From (1) :

a = 30 - b - - - (3)

Substituting a = 30 - b into (2)

30 - b - b = 20

30 - 2b = 20

30 - 20 = 2b

10 = 2b

b = 5

From (3) :

a = 30 - 5

a = 25

Hence,

a/b = 25 / 5 = 5

Hence, the value of a/b is 5

Answer:

(40,35)

Step-by-step explanation:

Well we can immediacy eliminate 2 options for ow becuase if you add them up they don’t equal 75 and in the equation it asked for x+y=75.

Now we just test out each x and y possibility

We know 5x+3 > 300

So lets try the first one

30 is x

45 is Y

5*30=150

45*3=135

Now if you add them

285

285 is not greater than 300 so thats wrong

SO B is correct

But lets check just in case

5*40=200

3*35= 105

305 IS greater than 300

305 > 300

SO B is correct

Given:

Considering only the factors of the form x - k.

To find:

The relationship between the k values and the zeros?​

Solution:

We know that, if (x-c) is a factor of a function f(x), then x=c is a zero of function f(x), i.e., f(c)=0, where, c is a constant.

It is given that, only the factors of the form x - k. Then by using the above theorem we can say that, k values are the zeros of the function.

The relationship between the k values and the zeros is defined as

​k values = Zeros of the function

Therefore, the k values are to zeros of the function.

What is the L.C.M OF 8,

5 AND 9

Step-by-step explanation:

The table for the function is,

x          -3     -2     1      4       5

g(x)       -14    -9     6     2      26

A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Given a function g(x) =  5x + 1

to find the values of g(x) for given values of x

when x = -3

g(x) =  5x + 1

g(-3) = 5(-3) + 1

g(-3) = -14

when x = -2

g(-2) = 5(-2) + 1

g(-2) = -9

when x = 1

g(1) = 5(1) + 1

g(1) = 6

when x = 4

g(4) = 5(4) + 1

g(4) = 21

when x = 5

g(5) = 5(5) + 1

g(5) = 26

Hence the values for g(x) are -14, -9, 6, 21, and 26 respectively.

Number of sides n = 9

Step 2: Find

Answer/Step-by-step explanation:

1. m<UTV = m<RTS = 85°

Reason: Definition of vertical angles.

Vertical angles are congruent to each other. m<UTV and m<RTS are vertical angles pair.

2. m<R + m<S + m<RTS = 180°

Reason: sum of interior angles of a ∆.

3. 3x + 2x + 85° = 180°

Reason: Substitution

4. x = 19

Reason: Algebra

Solving the equation algebraically, we would have the following:

3x + 2x + 85° = 180°

Add like terms

5x + 85 = 180

5x = 180 - 85 (subtraction property of equality)

5x = 95

Divide both sides by 5

x = 19

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Since, We know that;

The arc length (s) is given by,

⇒ s = r·θ

Here, We have;

r = 1

θ = 7π / 6

Hence, We get;

s = 1 × 7π/6

Standard deviation of the students = 0.408

The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote  

         = 0.408 X 1600

         = 652.8    

Step-by-step explanation:  

Step(i):-

Given sample size 'n' = 1600

95% confidence interval of the margin error is determined by

                      [tex]M.E = \frac{Z_{0.05} S.D}{\sqrt{n} }[/tex]

Level of significance = 0.05

Z₀.₀₅ = 1.96

Given Margin of error = 2% = 0.02

       [tex]M.E = \frac{Z_{0.05} S.D}{\sqrt{n} }[/tex]

       [tex]0.02 = \frac{1.96 X S.D}{\sqrt{1600} }[/tex]

      0.02 X √1600 = 1.96 X S.D

       [tex]S.D = \frac{0.02X\sqrt{1600} }{1.96} = 0.408[/tex]

Standard deviation of the students = 0.408

The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote  

         = 0.408 X 1600

Using the z-distribution, it is found that you would have to poll 2401 students.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].

There is no prior estimate, hence [tex]\pi = 0.5[/tex] is used.

The sample size is n for which M = 0.02, hence:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.02 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.02\sqrt{n} = 1.96(0.5)[/tex]

[tex]\sqrt{n} = \left(\frac{1.96(0.5)}{0.02}\right)[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96(0.5)}{0.02}\right)^2[/tex]

[tex]n = 2401[/tex]

-100 + 10 = -90

-90 + 90 = 0

Thus, adding a 90 in the empty box will make it 0.

Answer:

90

Step-by-step explanation:

This is the answer because:

1) -75 + (-25) = -100

2) -100 + 10 = -90

3) -90 + 90 = 0

Therefore, the answer is 90 because whenever a negative number is added with the same poitive number, it beomes a 0.
