Make a model of probability showing the set of outcome and the probability value of each outcome.

Answer:

Step-by-step explanation:

From the given information:

a) From the word SANTA CLAUS, outcomes are all distinct letters.

This implies that the outcomes are S, A, N, T, C, L, U, S

For  S, N, T, C, L, U, S letters, each of them is repeated once.

Thus, their respective probability = [tex]\dfrac{1}{10}[/tex]

A is repeated thrice, so probability for A = [tex]\dfrac{3}{10 }[/tex]

Using the probability distribution table; we have the following.

outcome      S        A        N        T        C        L        U        S

The difference between .375 and .475 is .1

The given expression is 500=100x, situations A could match this formula.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that,500=100x

If the distance is d, velocity is v and time is t then, The formula for the distance is,

Distance = velocity × time

d=vt

The distance is in miles, v is in miles per hour and t is an hour,

miles = miles/hour × hour

The correct representation of the expression is,

If the time in an hour will be x,

An object travels 500 miles at a rate of 100 miles per hour.

Distance = velocity × time

d=vt

500=100x

Thus, the given expression is 500=100x, situations A could match this formula.

Answer:

33.33%

Step-by-step explanation:

We need to calculate the unit selling price and cost of each cosmetics.

If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;

x = 1 cosmetic

since 360 = 12 cosmetic

cross multiply

12x = 360

x = 360/12

x = 30

Hence the unit cost price of the cosmetics will be Rs. 30

Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)

Selling price per unit = Rs. 40

Cost price per unit = Rs. 30

percent gain = SP-CP/CP * 100%

percent gain = 40-30/30 * 100

percent gain = 10/30 * 100

percent gain = 100/3

percent gain = 33.33%

Hence the percentage gain is 33.33%

Answer:

Area covered by wiper=area of arc(A0D)+area of traingleAOB+area of arc(BOC)

We know AO and OB are wipers,whose lengths are 1.5

In ∆ABC

AB^2+BC^2=AC^2

(1.5√3)^2+(1.5)^2=(AC)^2

2.25×3+2.25=(AC)^2

2.25×4=AC^2

AC=3

Also AO=1.5

similarly using Pythagoras theorem in ∆OBC

we get

OC=1.5

this shows that point O is the bisector of diagonal AC

so,AO=OC

also from property of rectangle we know that, diagonal bisects each other equally

so,O will also be the bisector of diagonal BD

hence OB=OD=1.5

AC=BD (property of triangle)

AC/2=BD/2

OB=OC,hence OB=OC=OD=OA=1.5=AD=BC

Hence OAD will be an equilateral triangle

so

angle OAD=60

similarly angleOBC=60

area of sector=angle of that sector ×area of circle/360

area of arc(AOD)+arc(BOC)=60/360 ×3.14 ×1.5×1.5 +60/360 ×3.14×1.5×1.5

=2×(60/360)×1.5×1.5

area of triangleAOB=area of rectangle/4 (diagonal divides the rectangle in 4 equal parts)

area of triangle=1.5×1.5√3/4

=>1.5×2.6/4=3.90/4

=0.975 or 0.98(approx)

Area covered by wiper=.98+2×60/360 ×3.14×1.5×1.5

=.98+0.75×3.14=2.35+0.97

=2.35+.98

Percentage of area of windshield covered by wiper=3.3×100/3.9=84.61

hence percentage of area of windshield covered by wiper is 85percent(approx)

Answer:

If the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.

Thus, the correct option is 'C'.

Step-by-step explanation:

Given the equation

[tex]-\frac{7}{2}n+5=-16[/tex]

Let me solve this using the correct method

[tex]-\frac{7}{2}n+5=-16[/tex]

Add -5 to both sides

[tex]-\frac{7}{2}n+5+\left(-5\right)=-16+\left(-5\right)[/tex]

simplify

[tex]-\frac{7}{2}n=-21[/tex]

Multiply both sides by -2/7

[tex]-\frac{7}{2}n\times -\frac{2}{7}=-21\times -\frac{2}{7}[/tex]

simplify

[tex]n=6[/tex]

Therefore, if the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.

Thus, the correct option is 'C'.

Answer:

The test statistics is  [tex]z = 2.47[/tex]

Step-by-step explanation:

From the question we are told that

    The  sample size is  n =  191 \  buses

     The sample mean is  [tex]\= x = 96 700 \ miles[/tex]

    The population standard deviation is  [tex]\sigma = 37 500 \ miles[/tex]

The null hypothesis is  [tex]H_o : \mu = 90 000[/tex]

The alternative hypothesis is  [tex]H_a : \mu > 90 000[/tex]

Generally the test statistics is mathematically represented as

         [tex]z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]

=>      [tex]z = \frac{96700 - 90 000 }{ \frac{37500}{\sqrt{191} } }[/tex]

=>      [tex]z = 2.47[/tex]

Answer:

P-value is a parameter to compare with the significance level in order to make decisions about rejecting or not the hypothesis

Step-by-step explanation:

When you are developing a hypothesis test, in order to compare two means  (  μ₁   and  μ₂ )  you have two hypothesis

Null Hypothesis                       H₀            μ₁   =      μ₂

And depending on the problem statement, the alternative  hypothesis could be

Alternative Hypothesis           Hₐ     (1)         μ₁    >     μ₂  

                                                            (2)        μ₁     <    μ₂

                                                             (3)       μ₁     ≠      μ₂

Now if the result of the test determines that H₀ is rejected  you accept in case

(1)   μ₁    >     μ₂

(2)  μ₁    >     μ₂  

(3)  μ₁     ≠      μ₂

In any case, you need a confidence Interval, and as consequence you established a significance level to do your test. These two concept defines the acceptance and the rejection region. Just for instance

CI  =  90% means that the acceptance region is 90 %, and at the same time, the rejection area is 10 %. That 10 % will be used as follows,

Case 1 you are developing a one tail-test to the left ( side of the curve )

Case 2 you are developing  a one tail-test to the right

Case 3 you are developing a two-tail test ( in that case you need to split α into two equal areas one for each tail.

Now P-value is a tool for decision is an area that you can compare with α to accept or reject H₀.

In our particular case suppose we are testing

H₀     μ₁   =      μ₂

Hₐ      μ₁     <    μ₂

Let´s say CI = 95    then  α = 5 %     α = 0,05

And we get  P-value  =  0,16

Then area   0,16 > 0,05   Then we are in the acceptance region

(that condition really implies that z(s) < z(c)  

Answer:

Option C: 11 is the correct answer.

Step-by-step explanation:

Given that:

Length of base of isosceles triangle = b =  x

The length of leg of triangle = a = 3x-7

Perimeter of triangle = 63

Perimeter of an isosceles triangle is given by

Perimeter = 2a + b

Putting values in the formula

63 = 2(3x-7) + x

63 = 6x-14+x

63 = 7x-14

63+14=7x-14+14

77=7x

7x=77

Dividing both sides by 7

[tex]\frac{7x}{7}=\frac{77}{7}\\x=11[/tex]

The value of x is 11.

Hence,

Option C: 11 is the correct answer.
