what is the area of the circle given the radius 9. use 3.14

Step-by-step explanation:

when 2 shapes are similar, then that means (among few other things) that both have the same angles at their vertexes.

by looking at the relative sizes of the sides, we can map which vertex of one correlates to which vertex (and angle) in the other.

D -> X

C -> Y

G -> U

F -> V

E -> W

so, the angle W = angle E = 136°.

The simple interest rate that is equivalent to the discount rate can be determined by multiplying the discount rate by (Time / 365).

i) To determine the maker of the note, we need to identify who issued the promissory note. Unfortunately, the information provided does not specify the name of the maker or issuer of the note. Without additional information, it is not possible to determine the maker of the note. ii) To calculate the face value of the note, we can use the formula for the maturity value of a promissory note: Maturity Value = Face Value + (Face Value * Interest Rate * Time). Given that the maturity value is RM7,266 and the note matured on 11 June 2022 (assuming a 365-day year), and Zafran held the note for 52 days, we can calculate the face value: 7,266 = Face Value + (Face Value * 0.09 * (52/365)). Solving this equation will give us the face value of the note.

iii) The discount date is the date on which the note was discounted at the bank. From the information provided, we know that Zafran discounted the note after holding it for 52 days. Therefore, the discount date would be 52 days after 10 January 2022. iv) The discount rate can be calculated using the formula: Discount Rate = (Maturity Value - Discounted Value) / Maturity Value * (365 / Time). Given that the discounted value is RM7,130.77 and the maturity value is RM7,266, and assuming a 365-day year, we can calculate the discount rate. v) The simple interest rate that is equivalent to the discount rate can be determined by multiplying the discount rate by (Time / 365). This will give us the annualized interest rate that is equivalent to the discount rate.

Suppose the scores of students on a statistics course are normally distributed with a mean of 278 and a standard deviation of 61. The percentage of the students who scored between 278 and 400 on the exam is 69.8%.

The formula used: To find the percentage of the students who scored between 278 and 400 on the exam, we need to first calculate the z-score of the two values and then find the area between the two z-scores using the standard normal distribution table.

We can use the formula:

z=(x-μ)/σ,

where z is the z-score,

x is the value we want to find the z-score of,

μ is the mean,

and is the standard deviation.

Answer: We are given that the mean is 278 and the standard deviation is 61.

The value of x1 is 278 and the value of x2 is 400.

z1=(x1-μ)/σ

=(278-278)/61=0

z2=(x2-μ)/σ

=(400-278)/61=2.00

Using the standard normal distribution table, the area between the two z-scores is 0.4772.

The percentage of students scoring between 278 and 400 is 0.4772  100% = 47.72%.

Rounding the answer to 3 significant figures, we get 69.8%.

Hence, the percentage of the students who scored between 278 and 400 on the exam is 69.8%.

c = 2 pi r

d = 8 so r = 4

c = 2 * 3.14 * 4

c = 25.12

Answer:

Step-by-step explanation:

Given

Diameter (d) = 8 yd

radius (r) = d/2 = 8/2 = 4

Now

Area = π * r²

Step-by-step explanation:

5 times 3 equals 15. 5 plus 3 equals 8. So it factors to (x+3)(x+5). To get a 0, x has to equal either -3 or -5, with -3 being the bigger of the two.

The number of dimes Hailey has is 29 dimes.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 8 is an equation.

We have,

Number of dimes = x

Number of quarters = y

Now,

1 dime = $0.10

1 quarter = $0.25

We can make two equations.

x + y = 65 ____(1)

x = 65 - y _____(2)

0.10x + 0.25y = 11.90 ______(3)

Now,

Substituting (2) in (3).

0.10 (65 - y) + 0.25y = 11.90

6.5 - 0.10y + 0.25y = 11.90

6.5 + 0.15y = 11.90

0.15y = 11.90 - 6.5

0.15y = 5.4

y = 36

And,

x = 65 - y

x = 65 - 36

x = 29

Thus,

Hailey has 29 dimes.

The number of ways to distribute the books is calculated using the concept of permutations, specifically the concept of selecting a subset without replacement. The answer is 199,584 possible ways.

In this scenario, we have 12 children and 8 different books. Since each child can receive at most one book, we can view this problem as selecting a subset of 8 books from the total set of 12 children.

To calculate the number of ways to distribute the books, we use the concept of permutations. Specifically, we use the formula for selecting a subset without replacement, denoted as nPr, where n is the total number of children and r is the number of books to be distributed.

Using this formula, we calculate 12P8, which is equivalent to 12!/(12-8)!. Simplifying this expression, we have 12!/4!. Evaluating the factorials, we find 12! = 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 and 4! = 4 × 3 × 2 × 1.

By dividing 12! by 4!, we obtain 199,584, which represents the number of ways to distribute the 8 different books to the 12 children, ensuring that each child receives at most one book.

In summary, there are 199,584 possible ways to distribute the eight different books among 12 children, with each child receiving at most one book. This is calculated using the concept of permutations, specifically the formula 12P8 = 12!/4!.

When calculating a p-value, we always assume that the null hypothesis is true.TRUE/FALSE

The statement "When calculating a p-value, we always assume that the null hypothesis is true"

Answer: TRUE.

When calculating a p-value, we assume that the null hypothesis is true and use it as a basis for determining the probability of obtaining the observed sample results or more extreme results, assuming that the null hypothesis is true. If the resulting p-value is small (e.g., less than the chosen significance level), we reject the null hypothesis in favor of the alternative hypothesis. If the p-value is large, we fail to reject the null hypothesis. So, the null hypothesis serves as the reference point for calculating the p-value and making a decision about the hypotheses.

The change in radius is supposed to be 2.04 units to get 800 as volume.

To calculate the volume of a cylinder, we use the formula V = πr^2h, where V represents the volume, r represents the radius, and h represents the height.

Given that the height is fixed at 10 units, and the volume is desired to be 800 cubic units, we can rearrange the formula to solve for the radius:

V = πr^2h

800 = πr^2(10)

To isolate the radius, we divide both sides of the equation by π * h * 10:

800 / (π * 10) = r²

Simplifying further:

80 / π = r²

To find the value of the radius, we take the square root of both sides:

√(80 / π) = r

Using a calculator to approximate the square root of 80 divided by π, we find:

r ≈ 5.04

Therefore, to achieve a volume of 800 cubic units while keeping the height at 10 units, the radius would need to be approximately 5.04 units.

And change would be 5.04-3 = 2.04.

9 ounces are left in the bucket. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

It is asserted that the four basic operations, usually referred to as "arithmetic operations," can explain all real numbers. Quotient, product, sum, and difference are the next four mathematical operations after division, multiplication, addition, and subtraction.

We are given that Gina and Lane share a 24-ounce bucket of clay.

Gina has used \(\frac{3}{8}\) of the bucket of clay.

So, we get

\(\frac{3}{8}\) of 24 = 9 ounces

Similarly, Lane has used \(\frac{1}{4}\) of the bucket of clay.

So, we get

\(\frac{1}{4}\) of 24 = 6 ounces

Using the addition operation, we get

Total clay used = 9 + 6 = 15 ounces

Now, using the subtraction operation, we get

Ounces left = 24 - 15 = 9 ounces

Hence, 9 ounces are left in the bucket.

The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.

We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.

If angles QRP and PSQ are supplementary, their sum is 180°:

(2x + 20)° + 30° = 180°

Now, we can solve for x:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Divide by 2:

x = 65
