Answer:

56.54in^2

Step-by-step explanation:

Answer 2

Answer:

18π in^2 (roughly 56.5 in^2)

Step-by-step explanation:

The area of a semicircle is half the area of a circle. So the area would be 1/2πr² instead of πr².

Since the diameter is 12 inches, the radius would be half of that, making the radius r=12/2=6 inches.

Plugging in r=6 into our formula, we see that the area of the semicircle is 1/2π(6)²=1/2π(36)=18π inches^2

So your final area is 18π in^2 (roughly 56.5 in^2)

PLEASE HELP THIS HAS A TIMER The following two-way table shows the distribution of daily traffic and weather issues in a certain large city.

A 4-column table with 3 rows. Column 1 has entries bad weather, good weather, total. Column 2 is labeled heavy traffic with entries 25, 55, 80. Column 3 is labeled Light traffic with entries 5, 15, 20. Column 4 is labeled Total with entries 30, 75, 100. The columns are titled daily traffic and the rows are titled weather conditions.

Suppose a day from this city is selected at random. Let event A = heavy traffic and event B = bad weather. Are events A and B independent?

No, P(A) = P(B|A).
No, P(A) ≠ P(A|B).
Yes, P(A) = P(A|B).
Yes, P(A) ≠ P(B|A).

Answers

Answer:

I believe the answer is (B).

Both are not independent, and the probability of A is 30/100.

While the probability for A|B is like 30/100(80/100) which does not equal 30/100.

I've been trying to figure out how to do it and stuff, and this seems the most reasonable answer. I'm taking it now. Goodluck

ED2021

The two events are not independent as the traffic is affected by the weather conditions.

What is independent probability?

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).

Let event A = heavy traffic and event B = bad weather.

P(A)=  25/30 and P(B)=25/30

Two events are said to be independent only when the change in one event affect the other event.

Here the two given events are not independent.

Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.

Hence, the two events are not independent as the traffic is affected by the weather conditions.

Answers

Answer:

I'm sorry that no one is helping you, the correct answers are A and F.

Step-by-step explanation:

The line's equation is [tex]y=\frac{1}{4} +3[/tex]. You know this because the slope of the line is found by subtracting the y-value of the two points and dividing it by the difference of the x-values, which would be [tex]\frac{6-4}{12-4} = \frac{2}{8} = \frac{1}{4}[/tex]. Using the slope, you can calculate the y-intercept of the equation, which you just multiply the slope by the distance to the y-axis and subtract that from the y-value of (4, 4), which you will get [tex]4 + (-4*\frac{1}{4}) = 4+(-1) = 3[/tex]. So the equation of the line is [tex]y=\frac{1}{4} +3[/tex]. When you simplify all the choices below, you'll get that only A and F are equivalent to the equation, so those are the correct choices.

Marcus receives an inheritance of ​$3,000. He decides to invest this money in a 11 ​-year certificate of deposit​ (CD) that pays 5.0 ​% interest compounded monthly. How much money will Marcus receive when he redeems the CD at the end of the ​11 years?

Answers

......:............................:.:.:...................

Marcus will receive $5,193.82 when he redeems the CD at the end of the ​11 years.

What is compound interest?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

A=P(1+r/n[tex])^{nt}[/tex]

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Marcus receives an inheritance of ​$3,000.

He decides to invest this money in an 11 ​-year certificate of deposit​ (CD) that pays 5.0 ​% interest compounded monthly.

P = $3,000

r =5%

t = 11 years

A=P(1+r/n[tex])^{nt}[/tex]

Substitute the values of P, r and t in the formula,

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A=P(1+r/n[tex])^{nt}[/tex]

A = 3,000.00(1 + 0.05/12[tex])^{(12)(11)}[/tex]

A = 3,000.00(1 + 0.0041666666666667[tex])^{132}[/tex]

A = $5,193.82

Therefore, Marcus will receive $5,193.82.

How many quart are 8/1/4 gallons

Answers

Given:

Consider the given gallons are [tex]8\dfrac{1}{4}[/tex] gallons.

To find:

The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]

Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Q1 : Gina writes the letters of the word PROBABILITY on separate cards. She picks one card at random. What is the probability that the card Gina selects is:

a) The letter B








b) A vowel











c) A letter before M in the alphabet?​

Answers

Answer:

2/11

4/11

6/11

Step-by-step explanation:

probability the letter B = number of times b appears in the word / total number of alphabets

total number of alphabets = 11

number of times b appears in the word = 2

2/11

a vowel = total number of vowels in the word / total number of alphabets

vowels include = a,e,i,o,u

vowels in the word = a, o, i

total number of vowels in the word = 4

4/11

A letter before M in the alphabet = total number of alphabets before m in the word  / total number of alphabets

letters before m = A, B, C, D, E, F, G, H, I, J, K, L

letters before m in the word = b,a, i , l

number of words before m = 6/11

You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?

Answers

Answer:

$17,276

Step-by-step explanation:

Given data

Time= 5 years

Principal= $14,000

Rate= 4.3%

We want to find the final amount

A=P(1+r)^t

Substitute

A= 14000(1+0.043)^5

A= 14000(1.043)^5

A= 14000*1.234

A=$17276

Hence the total amount is $17,276
