Solve the problem using Bayes' Theorem. Round the answer to the nearest hundredth, if necessary. For two events M and N, P(M)=0.6, P(N|M)=0.9, and P(N|M′)=0.2. Find P(M′|N.)

Answers

Answer 1

For two events M and N, P(M)=0.6, P(N|M)=0.9, and P(N|M′)=0.2. Then P(M′|N.) is 0.7

This can be easily solved if we know the formula:

P(A or B) = P(A) + P(B) - P(A and B)

So, for this problem, we can modify the formula to be:

P(M or N) = P(M) + P(N) - P(M and N)

Using given information, we can solve:

P(M or N) = P(M) + P(N) - P(M and N)

P(M or N) = 0.6 + 0.2 - 0.1

P(M or N) = 0.7

21. The two triangles below are similar. What is the perimeter of triangle XYZ? Y M 20 cm L 25 cm 15 cm X N 2 6 cm Z​

Answers

Answer:

175.5 cm.

Step-by-step explanation:

Since the triangles XYZ and LNM are similar, we know that their corresponding sides are proportional. Specifically, we have:

XY / LN = XZ / LM = YZ / NM

Substituting in the given lengths, we have:

XY / 25 = XZ / 20 = YZ / 15

Multiplying by the lowest common denominator of 300, we get:

12XY = 15XZ = 20YZ

Let's use the first equation to solve for XY:

XY = (15/12) XZ = (5/4) XZ

Now, let's use the third equation to solve for YZ:

YZ = (12/20) XZ = (3/5) XZ

Finally, we can use the fact that the perimeter of triangle XYZ is the sum of its side lengths:

Perimeter of XYZ = XY + YZ + XZ

= (5/4) XZ + (3/5) XZ + XZ

= (39/20) XZ

To find XZ, we can use the second equation:

XZ / 20 = XY / 25

XZ = (20/25) XY

XZ = (4/5) XY

XZ = (4/5) (5/4) YZ

XZ = YZ

So, XZ = YZ = (3/5) XZ.

Substituting this into the expression for the perimeter of XYZ, we have:

Perimeter of XYZ = (39/20) XZ

= (39/20) (3/5) YZ

= (117/100) YZ

= (117/100) (15)

= 175.5 cm

Therefore, the perimeter of triangle XYZ is 175.5 cm.

The largest value for 60 such that 0 < x - c < 5 - f(x) < e is x < -5/7.

To determine the largest open interval about c on which the inequality f(x) - LI < e holds, we need to find the interval where the difference between f(x) and LI is less than e.

Given:

f(x) = 8x + 81

L = 11

c = 5

e = 0.04

We can start by substituting the values of L and c into the function f(x):

f(x) - LI = 8x + 81 - 11(5) = 8x + 81 - 55 = 8x + 26

Now we want to find the interval where 8x + 26 < e. Substituting e = 0.04, we have:

8x + 26 < 0.04

Subtracting 26 from both sides of the inequality, we get:

8x < -25.96

Dividing both sides by 8, we obtain:

x < -3.245

Therefore, the largest open interval about c = 5 on which the inequality f(x) - LI < e holds is (-∞, -3.245). In interval notation, this can be written as (-∞, -3.245).

Now let's determine the largest value for 60 such that 0 < x - c < 5 - f(x) < e.

Substituting the values of c and f(x) into the inequality, we have:

0 < x - 5 < 5 - (8x + 81)

Simplifying the inequality, we get:

0 < x - 5 < -8x - 76

Combining like terms, we have:

8x < x - 5 < -76

Adding 76 to all sides of the inequality, we obtain:

8x + 81 < x + 76 < 0

Subtracting x from all sides, we get:

7x + 81 < 76 < -x

Subtracting 81 from all sides, we have:

7x < -5 < -x

To isolate x, we need to multiply all sides by -1. Since we're looking for the largest value for 60, we will multiply all sides by -1 and reverse the inequality signs:

-x > 5 > 7x

Dividing all sides by 7 and flipping the inequality signs, we have:

x < -5/7 < -x/7

Since we want the largest value for 60, we need to maximize x. So, x must be less than -5/7.

Therefore, the largest value for 60 such that 0 < x - c < 5 - f(x) < e is x < -5/7.

carlos can write 3 to 4 pages in his journal in 2/3 hour. if he writes for 5 hours, what's a reasonable number of pages he can write in that time?

Answers

Answer:

23, 24, 25, 26, 27, 28, 29, or 30

22.5 ≤ p ≤ 30

Step-by-step explanation:

So we know that in 2/3 hours, Carlos can write 3 to 4 pages.

First, lets find how many 2/3's are in 5. Lets divide 5 by 2/3.

\(\frac{5}{\frac{2}{3}}=7.5\)

So there are 7.5 2/3's in 5.

Now, lets assume Carlos writes 4 pages per 2/3 hours consistently throughout that 5 hours. This would yield the maximum amount of pages Carlos can write in 5 hours.

7.5(4) = 30

So the maximum amount of pages Carlos can write in 5 hours is 30.

Now, lets assume Carlos writes 3 pages per 2/3 hours consistently throughout that 5 hours. This would yield the minimum amount of pages Carlos can write in 5 hours.

7.5(3) = 22.5

So the minimum amount of pages Carlos can write in 5 hours is 22.5.

Now we can write the information that we found as an inequality. Lets make p equal to the pages that Carlos can write in 5 hours.

22.5 ≤ p ≤ 30

Any value greater than to equal to 22.5 and less than or equal to 30 would be reasonable.

The total area from the graph is 2.737.

What is area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

First of all, lets calculate the points of intersection (P, Q, R)

x²+3=(x+2) +5

x²-2=√(x+2)

x⁴+4-4x²=x+2

x⁴-4x²-x+2=0

(x-2)(x³+2x²-1)=0

(x-2)(x+1)(x²+x-1)=0

x=2, -1, -1±√(1+4)/2

Clearly, the x-coordinate of Q is -1, P is -1-√5/2, R is -1+√5/2, S is 2

So the limit of integration will be

P( (-1-√5)/2, (-1-√5/2)² +3)=P((-1-√5)/2, (3+√5/2))

Q(-1, (-1)²+3)=Q(-1, 4)

Area A:

\(\int\limits^\frac{3+\sqrt{5} }{2} _4 {-\sqrt{-y-3}-((y-5)^2 -2)} \, dx\)

= \([\frac{-(y-3)^\frac{3}{2} }{\frac{3}{2} }-\frac{(y-5)^3}{3}+3y]^{\frac{3+\sqrt{5} }{2} }_4\)

= 2.07

Area B:

\(\int\limits^\frac{-1+\sqrt{5} }{2} _4 {-\sqrt{x+2}+5-(x^2+3)} \, dx\)

= \([\frac{-(x+2)^\frac{3}{2} }{\frac{3}{2} }+5x-\frac{x^3}{3}-3x]^{\frac{-1+\sqrt{5} }{2} }_{-1}\)

= 0.667

Total area = 2.07+0.667

= 2.737

Total economic cost:

Local store = $114 + [1/4 hours x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $144

Across town = $86 + [1/2 hours x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $131

Neighboring city = $60 + [1 hour x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $135

Derek works 43 hours at a rate of pay of $15 per hour. He receives double pay over 40 hours. What is his gross pay?

Answers

The Gross pay which Derek gets is 690 dollars.

What is Gross Pay?

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages. The amount remaining after all withholdings are accounted for is net pay or take-home pay.

Here, Total hours worked by Derek = 43 hours

Rate of pay = $15 per hour

Rate of pay beyond 40 hours = $30 per hour

Now,

Rate of pay for the first 40 hours = 40 X 15 = $ 600

Since the pay rate doubles after 40 hours,

Rate of pay for the remaining 3 hours = 3 X 30 = $ 90

Gross Pay = 600 + 90 = $ 690

  9 = x . . . . . . . . . subtract 6

The measure of x is 9 inches.

Additional comment

You could also write the proportion ...

  6/4 = x/(10 -4)

  x = 36/4 = 9 . . . . . . . multiply by 6

You can see this if you draw a horizontal line through the figure at the top of the side marked 4 in.
