Answer: The circumference of the circle is approximately 12.57 meters

Step-by-step explanation:

The circumference of a circle can be found by multiplying its diameter by π (pi), or by multiplying twice the radius by π.

In this case, the radius is 2 meters, so twice the radius is 4 meters.

Therefore, the circumference of the circle is:

C = 2πr = 2π(2) = 4π ≈ 12.57 meters

So the circumference of the circle is approximately 12.57 meters.

Answer:

The answer for Circumference is 12.56m

Step-by-step explanation:

If Joe covers the cylindrical planter having radius of 4 inches and height of  6 inches, then amount of moss required is 251.2 inches square.

In order to find the amount of moss required to cover the cylindrical-planter, we need to find the surface-area of the planter,

The formula for the Surface-Area(S) of a cylinder-planter is:

⇒ S = 2πrh + 2πr², Where: r denotes radius base, h denotes height  cylinder-planter,

We know that radius of planter is 4 inches, height is 6 inches,

Substituting the values,

We get;

S = 2×π×(4)×(6) + 2×π×(4)²

S = 48π + 32π

S = 80π = 80×3.14 = 251.2 inches square.

Therefore, the surface area of the cylindrical planter is 251.2 square inches. This is the amount of moss that Joe will need to cover it.

It cost Tom $8,334 to buy the stock.

Tom's net gain or loss is $-666.

Tom's annual rate of return is -8.0%.

We have,

To calculate Tom's cost to buy the stock, we multiply the number of shares by the cost per share and then add the commission paid to the broker:

Cost = (750 * 11.06) + 12 = $8,322 + $12 = $8,334

To calculate Tom's proceeds from selling the stock, we multiply the number of shares by the price per share and then subtract the commission paid to the broker:

Proceeds = (750 * 10.24) - 12 = $7,680 - $12 = $7,668

To calculate Tom's net gain or loss, we subtract the cost from the proceeds:

Net gain/loss = $7,668 - $8,334 = -$666

Tom has a net loss of $666, meaning he lost money on this investment.

To calculate Tom's annual rate of return, we need to know how long he held the stock. Let's assume he held the stock for one year. Then, his rate of return is:

Rate of return = (Proceeds - Cost) / Cost * 100% * (1 / Time)

where Time is the time period for which the rate of return is being calculated (in years).

Plugging in the values we have:

Rate of return = (-$666 / $8,334) * 100% * (1 / 1) = -8.0%

Tom's annual rate of return is -8.0%, meaning he lost 8% of his investment over the course of one year.

Thus,

It cost Tom $8,334 to buy the stock.

Tom's net gain or loss is $-666.

Tom's annual rate of return is -8.0%.

The probability of at most 8 of the students being full-time is approximately 0.988, or 98.8%.

To answer this question, we can use the binomial distribution function in R. The formula for the binomial distribution is:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where:
- P(X=k) is the probability of getting exactly k successes
- n is the total number of trials
- p is the probability of success in each trial
- (n choose k) is the number of ways to choose k items from a set of n items

(a) To find the probability that exactly 6 of the students will be full-time, we can use the following command in R:

dbinom(6, 10, 0.6)

This will give us the probability of getting exactly 6 full-time students out of a random sample of 10 students, assuming that the probability of a student being full-time is 0.6 (since there are 30 full-time students out of a total of 50 students).

The output of this command is:

[1] 0.2508227

So the probability of exactly 6 of the students being full-time is approximately 0.251, or 25.1%.

(b) To find the probability that at most 8 of the students will be full-time, we can use the following command in R:

pbinom(8, 10, 0.6)

This will give us the probability of getting 8 or fewer full-time students out of a random sample of 10 students.

The output of this command is:

Answer:

-7 and -5

Step-by-step explanation:

The easiest way to solve this problem is to list the simplest ways to get 35. These are the factors.

7*5=35

1*35=35

1+35 gives us 36, and 35-1 gives 34. So, 1 and 35 can not be our mystery numbers.

7-5 given 2, and 7+5 gives 12. Yay! We found a way to get 12 with numbers that multiply to 35!

But wait! This gives positive 12, not negative. Recall that a negative plus a negative will give a negative, and a negative times and negative will give a positive. So, by making 7 and 5 negative, we get:

-7*-5=35

-7+(-5)=-12

-7 and -5 are the answers.

In Mathematics and Geometry, a parallelogram simply refers to a four-sided geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that is composed of two (2) equal and parallel opposite sides.

Since side AB is parallel to side DC and AD is parallel to side BC, we can logically deduce that quadrilateral ABCD is a parallelogram. Additionally, the diagonals of this parallelogram bisect each other at the midpoint O;

OC ≅ OD

OC = 1/2 × (AC) = 1/2 × 20 = 10

OD = 1/2(BD) = 1/2 × 20 = 10

Now, we can calculate the perimeter of triangle COD as follows;

Perimeter of triangle COD = OC + OD + CD

The number of such functions are 16,807

The number of functions that are injective are 5.

The number of functions that are surjective are 20.

The number of functions that are bijective are one.

Functions are an essential concept in mathematics and are used to describe relationships between sets. In this question, we are interested in functions from a set of five elements {A, B, C, D, E} to a set of seven elements {1, 2, 3, 4, 5, 6, 7}. Specifically, we want to know how many such functions exist and what properties they have.

To answer the first question, we need to determine how many functions are possible. A function from set A to set B assigns each element of A to a unique element of B. In this case, we have five choices for where to send each element of A, and there are seven possible choices for the destination, so there are a total of 7⁵ = 16,807 possible functions.

Next, we consider the property of injectivity, which means that each element of the codomain (set B in this case) is assigned to by at most one element of the domain (set A). In other words, no two distinct elements of A are mapped to the same element of B.

Next, we consider the property of surjectivity, which means that each element of the codomain is assigned to by at least one element of the domain. In other words, every element of B is the image of at least one element of A under the function.

There are 9,405,814 distinct dolls that contain the undesirable statement among their four exclamations.

Since each doll has four exclamations, the total number of distinct dolls can be calculated as the number of ways to choose four statements from a set of 270 statements, which is given by the formula for combinations:

C(270, 4) = 270! / (4! * (270 - 4)!) = 4,012,060

Therefore, there are 4,012,060 distinct dolls with four exclamations.

To calculate the number of distinct dolls that contain the undesirable statement among their four exclamations, we can use the formula for combinations again, this time choosing three statements from the remaining 269 statements and one statement from the undesirable statement:

C(269, 3) * C(1, 1) = 269! / (3! * (269 - 3)!) * 1 = 9,405,814

To find the limit of the given expression as x approaches 0, we will use l'Hospital's Rule because the expression is in the indeterminate form 0/0. The given expression is: lim (x→0) [(√(1 + 9x) - √(1 - 2x))/x]

First, let's find the derivative of the numerator and denominator with respect to x. Numerator's derivative: d/dx [√(1 + 9x) - √(1 - 2x)] = (9/2) * (1/√(1 + 9x)) - (2/2) * (1/√(1 - 2x)) Denominator's derivative: d/dx [x] = 1

Now, apply l'Hospital's Rule and find the limit of the derivative: lim (x→0) [(9/2) * (1/√(1 + 9x)) - (2/2) * (1/√(1 - 2x))]

As x approaches 0: = (9/2) * (1/√(1 + 9*0)) - (2/2) * (1/√(1 - 2*0)) = (9/2) * (1/√1) - (2/2) * (1/√1) = (9/2) - (2/2) = (9 - 2)/2 = 7/2
