A man has mislaid his wallet. He thinks there is a 0.4 chance that the wallet is somewhere in his bedroom, a 0.1 chance it is in the kitchen, a 0.2 chance it is in the bathroom, and a 0.15 chance it is in the living room. What is the probability that the wallet is a) somewhere else? b) in either the bedroom or the kitchen?

Answer:

P(45<X<81) = P(-3<z<3)=0.9974 or 99.74%

Step-by-step explanation:

Mean = 63

Standard Deviation =6

We need to find probability that X lies between 45 and 81 i.e P(45<X<81)

First we will find z-score for X=45 and X=81

For X=45 the z-score can be found using formula:  [tex]z-score=\frac{X-\mu}{\sigma}[/tex]

Putting values and finding z-score

[tex]z-score=\frac{X-\mu}{\sigma}\\z-score=\frac{45-63}{6}\\z-score=-3[/tex]

For X=45, z-score is -3

For X=81 the z-score can be found using formula:  [tex]z-score=\frac{X-\mu}{\sigma}[/tex]

Putting values and finding z-score

[tex]z-score=\frac{X-\mu}{\sigma}\\z-score=\frac{81-63}{6}\\z-score=3[/tex]

For X=81, z-score is 3

Now finding the probability of P(-3<z<3)

It can be solved as:

P(-3<z<3)=P(z<3)-P(z<-3)

Looking at the z-score table to find

P(z<3)= 0.9987

P(z<-3)=0.0013

So, P(-3<z<3)=P(z<3)-P(z<-3)

P(-3<z<3)=0.9987 - 0.0013

P(-3<z<3)=0.9974

or P(-3<z<3)= 99.74%

So, P(45<X<81) = P(-3<z<3)=0.9974 or 99.74%

Answer:

NO

Step-by-step explanation:

no, 9/31 is not an irrational number. ... So we have shown that the square root of any non-square cannot be rational; hence, it is irrational.

The square root of 9/31 rational is not a rational number.

We have given that  9/31.

We have to determine is the square root of 9/31 rational

A rational number is a number that can be expressed as the quotient of two integers, with the denominator not equal to zero.

9/31 is not an irrational number.

So we have shown that the square root of any non-square cannot be rational.

hence, it is irrational.

Therefore it is not a rational number.

Step-by-step explanation:

average rate of change in steel production over the eight days=-0.15 tons per day

Step-by-step explanation:

The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons.

Production is dropped by 1.2 tons, so its negative

Average rate of change = Change in production / number of days

Average rate of change = -1.2/ 8= -0.15

so sorry -0.15

Answer:

30° and 150°

Step-by-step explanation:

supplementary means that the sum of the measures = 180

let's say 1 angle is labled ∠A and the other ∠B

m∠A + m∠B = 180°

however, m∠A = 5 * m∠B

so, by substituting that:

5*m∠B + m∠B = 180°

6*m∠B = 180°

m∠B = 30°

m∠A = 150°

Answer:

the standard deviation of the critical path is 8

Step-by-step explanation:

The computation of the standard deviation of the critical path is shown below:

As we know that

Variance = Standard deviation^2

Now the variance of the critical path is

= Variance 1 + variance 2 + variance 3 + variance 4

= 4^2 + 4^2 + 4^2 + 4^2

= 64

Now the standard deviation would be

= √64

= 8

hence, the standard deviation of the critical path is 8

Answer:

  (ii) center: (-3, 6)

  (iii) A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

  (iv) (x +3)²/100 +(y -6)²/51 = 1

Step-by-step explanation:

(ii) The center is the midpoint between the foci:

  center = ((-10, 6) +(4, 6))/2 = (-10+4, 6+6)/2

  center = (-3, 6)

__

(iii) The vertices are the center plus or minus the semi-major axis length in the x-direction: (-3±10, 6).

The semi-minor axis length is the root of the difference of squares of the semi-major axis and the center-focus distance:

  semi-minor axis = √(10² -7²)

  semi-minor axis = √51

So, the co-vertices are the center plus or minus this value in the y-direction: (-3, 6±√51)

Using the labeling in the drawing the various points are ...

  A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

__

(iv) For center (h, k) and semi-axis lengths 'a' and 'b' the equation of an ellipse is ...

  (x -h)²/a² +(y -k)²/b² = 1

For the center and axes here, the equation is ...

  (x +3)²/100 +(y -6)²/51 = 1
