P(B/A)=P(A∩B)/P(A)

so P(A∩B)=P(A)P(B/A)=0.6*0.22=0.132

P(A∪B)=P(A)+P(B)-P(A∩B)=0.6+0.2-0.132=0.668

Answer:

Numbers 1,0,8,2 would lie on y-axis.

Step-by-step explanation:

This is because for example, (0,1)

we must prefer 0 as x-axis and 1 as y-axis. That's means left number or side will always be x-axis and right side will always be y-axis.

Answer: (0, 1)

Step-by-step explanation:

When the x is 0 is lies on the y axis.

Step-by-step explanation:

let the larger number be x and smaller number be y

according to this question

x=y+33----------(1)

y+33+5y=129----------(2)

6y+33=129

y=16

x=16+33(takimg equation (1)

x=49

Answer:

Larger number: 49.

Smaller number: 16.

Step-by-step explanation:

Let's say that the larger number is represented by y, and the smaller is represented by x.

y = 33 + x

y + 5 * x = 129

(33 + x) + 5x = 129

6x + 33 = 129

6x = 96

x = 16

y = 33 + 16

y = 49

Check our work...

49 + 5 * 16 = 49 + 80 = 129

49 = 33 + 16 = 49

Since it all works out, the larger number is 49 and the smaller number is 16.

Answer:

39.16% probability of selecting three Democrats and three Republicans

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the people are selected is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

3 Democrats, from a set of 8.

3 Republicans, from a set of 8.

[tex]D = C_{8,3}*C_{8,3} = (C_{8,3})^{2} = (\frac{8!}{3!5!})^{2} = 56^2 = 3136[/tex]

Total outcomes:

6 people from a set of 16.

[tex]T = \frac{16!}{6!10!} = 8008[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{3136}{8008} = 0.3916[/tex]

39.16% probability of selecting three Democrats and three Republicans

Answer:

175,760,000 possible standard plates

Step-by-step explanation:

For digits, there are 10 possible values (0 to 9)

For letters, there are 26 possible alphabet (a - z)

Assuming the letter case is irrelevant.

Given that the license plate consists of;

2 digits, followed by 3 letters, followed by 2 digits

N1 = 2 digits = 10 × 10

N2 = 3 letters = 26× 26 × 26

N3 = 2 digits = 10×10

In the absence of any other conditions, the number of possible plates in this system is;

N = the product of N1, N2 and N3 above.

N = N1 × N2 × N3

N = 10×10×26×26×26×10×10

N = 175,760,000 possible standard plates

Answer:

A: x=1/2  is an extraneous solution.

Step-by-step explanation:

Answer:

A.) NM= x

C.) LM = x√2

E.) tan (45°) = 1

Step-by-step explanation:

If the legs are both x, then the hypotenuse is equal to [tex]x\sqrt{2[/tex]

Therefore, LM= [tex]x\sqrt{2[/tex] is correct and MN= x

The true statements regarding the given isosceles right triangle ΔLMN are:

An isosceles triangle is a triangle where two sides and their corresponding angles are equal.

A right triangle is a triangle with one angle = 90°.

An isosceles right triangle is a right-angled triangle with two legs including the right angle are equal. Their corresponding angles are equal and each of them = 45°. So, the three angles of an isosceles right triangle are 45°, 45°, and 90°, always.

In the figure, we can see that we have a ΔLMN, with ∠L = 45°, ∠M = 45°, and ∠N = 90°. Also, we can see that LN = x.

The given angles of ΔLMN determine that it is an isosceles right triangle with a right angle at N.

Since, the two legs involving the right angle, that is N, are equal, we can say that, NM = LN = x.

The hypotenuse of the ΔLMN, that is the side opposite to ∠N, that is LM, can be found using the Pythagoras theorem, by which in a right-angled triangle,

Hypotenuse² = Base² + Perpendicular².

∴ LM² = LN² + NM² = x² + x² = 2x².

or, LM = √(2x²) = x√2.

The tangent of an angle ∅, that is, tan ∅ is computed using the formula,

tan ∅ = Perpendicular/Base.

To calculate tan 45°, that is, tangent to ∠L, we take Perpendicular = NM and Base = LN.

∴ tan 45° = NM/LN = x/x = 1.

Now, we check all the given options:

∴ The true statements regarding the given isosceles right triangle ΔLMN are:

Answer: 420 words

Step-by-step explanation:

First find how much he did the first day by doing 1/5*2400=480.

Then find out how much he did the second day by doing 2400-480=1920, then doing 1920*(2/3)=1280.

Then, because he did 220 words the third day, simply do 2400-480-1280-220=420.

Step-by-step explanation:

Answer:

70% of the reports will take 525 minutes (8 hours, 45 minutes) to file.

Step-by-step explanation:

Given;

total number of Meredith's report, N = 10

average time taken for each report to be filed is, t = 75 minutes per report

let the total time for the 10 reports = T

[tex]\frac{T}{N} = t\\\\T = N*t \\\\T = 10 *75\\\\T = 750 \ minutes[/tex]

The total time for the 10 reports is 750 minutes.

Time taken to file 70 % of 10 reports = (0.7 x 10) x (75 mins)

                                                             = 0.7 x 750

                                                             = 525 minutes (8 hours, 45 minutes)

Therefore, 70% of the reports will take 525 minutes (8 hours, 45 minutes) to file.

Answer: 0.58

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

So we can think of 58% as the ratio 58 to 100 or 58/100.

Dividing by 100 moves the decimal point 2 places to the left so 58/100 would move the decimal point 2 places to the left which would give us .58 or 0.58. So 58% can be written as the decimal 0.58.

Answer:

Step-by-step explanation:

Relative growth rate= Growth rate/population

Given: constant relative growth rate=0.7233

0.7233=[tex]\frac{dP/dt}{P}[/tex]

[tex]\frac{dP}{dt} =0.7233 P[/tex]

Theorem 2 states that solutions of the differential equation dy/dt = ky are in the form:    y(t)=y(0)[tex]e^k^t[/tex]

Writing the soltuion of our dif. equation as:

P(t)=P(0)[tex]e^{0.7233t}[/tex]

since on day zero the population consists of four members.

P(t)=4[tex]e^{0.7233t}[/tex]

next is to find the population size after six days. i.e t=6

P(6)=4[tex]e^{0.7233\times 6}[/tex] ≈ 307 members

Answer:

The required sample size increases.

Step-by-step explanation:

The margin of error of a confidence interval is given by:

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which z is related to the confidence level(the higher the confidence level the higher z), [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

In this question:

The confidence level decreases, so z decreases.

For the margin of error to stay the same, the sample size also has to decrease.

The required sample size increases.

Good luck on your assignment.

To solve this system, I would use substitution.

Since our first equation tells us that y = 2x - 3, we can substitute a

2x - 3 in for the y in our second equation to get 2x - 3 - 9 = -x.

Simplifying on the left we get 2x - 12 = -x.

Moving the 2x to the right, we have -12 = -3x.

Now divide both sides by -3 and we have 4 = x.

To find y, plug 4 back into either one of the original equations.

I'll go with the first one.

So we have y = 2(4) - 3.

Solving from here, we find that y = 5.

So the solution to this system is (4,5).
