Answer 1

Answer:

38 in

Step-by-step explanation:

Ok, so the bottom part is a rectangle and the top part is a triangle. We’re gonna split those into two different shapes.

8 * 4 = 32, this is the area of the bottom rectangle.

To get the side length of the top triangle, we have to subtract 8 from 11.

11 - 8 = 3

(3 * 4)/2 = 6, this is the area of the top triangle.

Add the two areas, 32 + 6 = 38

And that’s it, maybe, I think.

Answer: Assuming that event A has occurred

Step-by-step explanation:

The conditional probability of B given A can be found by assuming that event A has occurred, and then calculating the probability that event B will occur.

So, the correct answer is d.

The conditional probability of B given A, denoted as P(B|A), represents the probability of event B occurring given that event A has already occurred.

It is calculated by assuming that event A has occurred and then determining the probability of event B occurring under that assumption.

Mathematically, the conditional probability is calculated as:

P(B|A) = P(A and B) / P(A)

Where P(A and B) represents the probability of both events A and B occurring together, and P(A) represents the probability of event A occurring.

Therefore, option d. assumes that event A has occurred and then calculates the probability that event B will occur, which aligns with the definition of conditional probability.

Answers

Answer: x=7

Step-by-step explanation:

(11x-32)=45

We move all terms to the left:

(11x-32)-(45)=0

We get rid of parentheses

11x-32-45=0

We add all the numbers together, and all the variables

11x-77=0

We move all terms containing x to the left, all other terms to the right

11x=77

No, because when adding 1 to any odd number it will become even, and all even numbers besides 2 are not prime. This means that if n was 1 the resulting number would be prime, since 2 is prime.

what is j+m, j times m and j divided by m

Answers

Answer:

j + m

[tex]\frac{j}{m}[/tex]

Step-by-step explanation:

We have j and m and are asked to add, multiply and divide them both.

When it comes to adding, its all about like terms, if the terms are not alike meaning ending in the same variable they cannot be added.

Therefore j + m is equal to just j + m.

Now for multiplying, this is free rule, you can freely multiply any variable you want without reprecussion.

Therefore, j * m is equal to jm.

Now for dividing, this works like adding, where you can divide only if the terms are the same, since j and m are not the same. J divided by M is equal to [tex]\frac{j}{m}[/tex]

a closed circular water tank in a subdivision is made up of concreate aluminum. its outer diameter is 8.4 m and its height is 12 m. if it is to be painted on the exterior, then how much total surface area is to be painted?

Answers

Answer:

122.7792 sq. m

Step-by-step explanation:

diameter= 8.4 m

therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)

height = h= 12 m

only the exterior is to painted so the total surface area of the cylinder is taken,

total surface area of cylinder = 2π r( h+r)

=2* 3.14* 4.2*(12+4.2)

=122.7792 sq. m

11) To approach a runway, a pilot must begin a 10° descent

starting from a height of 0.38 miles above the ground. At

the start of his approach, how far, d, is the plane from the

runway to the nearest tenth of a mile?

Answers

Answer:

the plane 2.2 miles away from the runway

Step-by-step explanation:

Given the data in the question and as illustrated in the image below;

from the image, using trigonometric ratio;

SOH CAH TOA

sin = opposite / hypotenuse

sin10° = 0.38 / x

xsin10° = 0.38

x = 0.38 / sin10°

x = 0.38 / 0.173648

x = 2.1883 miles ≈ 2.2 miles { the nearest tenth of a mile }

Therefore, the plane 2.2 miles away from the runway

A certain town never has two sunny days in a row. Each day is classified as being either sunny, cloudy (but dry), or rainy. If it is sunny one day, then it is equally likely to be either cloudy or rainy the next day. If it is rainy or cloudy one day, then there is one chance in two that it will be the same the next day, and if it changes then it is equally likely to be either of the other two possibilities. In the long run, what proportion of days are sunny

Answers

Answer:

the proportion of days that are Sunny is 0.2

Step-by-step explanation:

Given the data in the question;

Using markov chain;

3 states; Sunny(1), Cloudy(2) and Rainy(3)

Now, based on given conditions, the transition matrix can be obtained in the following way;

[tex]\left[\begin{array}{ccc}0&0.5&0.5\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right][/tex]

so let the proportion of sunny, cloudy and rainy days be S, C and R respectively.

such that, from column 1

S = 0.25C + 0.25R -------------let this be equation 1

from column 2

0.5C = 0.5S + 0.25R

divided through by 0.5

C = S + 0.5R ---------------------- let this be equation 2

now putting equation 2 into equation;

S = 0.25(S + 0.5R) + 0.25R

S = 0.25S + 0.125R + 0.25R

S - 0.25S = 0.375R

0.75S = 0.375R

S = 0.375R / 0.75

S = 0.5R

Therefore,

from equation 2; C = S + 0.5R

input S = 0.5R

C = 0.5R + 0.5R

C = R

Now, we know that, the sum of the three proportion should be equal to one;

S + C + R = 1

since C = R and S = 0.5R

we substitute

0.5R + R + R = 1

2.5R = 1

R = 1/2.5

R = 0.4

Hence, the proportion of days that are Rainy is 0.4

C = R

C = 0.4

Hence, the proportion of days that are Cloudy is 0.4

S = 0.5R

S = 0.5(0.4)

S = 0.2

Hence, the proportion of days that are Sunny is 0.2

I WILL GIVE BRAINLIST AND LOTS OF POINTS Read the passage.A Flag with 50 StarsThe first American flag to have red and white stripes and white stars on a blue field was flown in 1776, shortly after the United States declared its independence from Great Britain. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Read the excerpt from A Flag with 50 Stars. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag.
