A = P(1+r/n)nt

CI = A-P

Where,

CI = Compounded interest

A = Final amount

P = Principal

t = Time period in years

n = Number of compounding periods per year

r = Interest rate

Answer:

The circumference is 45.2yd

Step-by-step explanation:

Given

[tex]d = 14.4[/tex] --- diameter

Required

Determine the circumference

The circumference is calculated as:

[tex]C =\pi d[/tex]

So, we have:

[tex]C =\pi * 14.4[/tex]

Take pi a 3.14

[tex]C =3.14 * 14.4[/tex]

[tex]C =45.216[/tex]

Approximate

[tex]C =45.2yd[/tex]

Step-by-step explanation:

Dilation involves changing the size of a figure

The endpoints of the image are (-2,-1) and (6,1)

The coordinates of the pre-image are give as:

(2,2) and (6,2)

The scale factor is given as:

k = 2

The center of dilation is given as:

(a,b) = (6,5)

The coordinates of the image are then calculated as:

[tex](x,y) \to (k(x -a) + a, k(y -b) + b)[/tex]

For (2,2), we have:

[tex](x,y) \to (2(2 -6) + 6, 2(2 - 5) + 5)[/tex]

[tex](x,y) \to (-2, -1)[/tex]

For (6,2), we have:

[tex](x,y) \to (2(6 -6) + 6, 2(2 - 5) + 5)[/tex]

[tex](x,y) \to (6, -1)[/tex]

Hence, the endpoints of the image are (-2,-1) and (6,1)

Answer:

+/- 2 both work.

Step-by-step explanation:

Remark

To make sure they are even, you need to use 2x and 2x + 2

Equation

2x (2x + 2) = 2x + 2x + 2 + 14      Combine like terms on the right

Solution

2x(2x + 2) = 4x  + 16                    Remove the brackets

4x^2 + 4x  = 4x + 16                    Subtract 4x from both sides.

          -4x    -4x

4x^2  = 16                                   Divide by 4

x^2 = 16/4

x^2 = 4                                        Take the square root of both sides

x = +/- 2

Answer:

The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.

Step-by-step explanation:

The Poisson distribution is used to solve this question, as we have only the mean. In this distribution, the standard deviation is the square root of the mean.

In this question, we have that:

Species are discovered at a rate of once every 7 months.

A supplement to a guide is planned to be published after 20 new species have been discovered.

a) What are the expected value and standard deviation of the number of months (treated as a continuous measure of time) until the supplement is published?

Mean is: 7*20 = 140 months.

Standard deviation is [tex]\sqrt{140}[/tex] = 11.8 months.

The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.

Answer:

The researcher needs 20 milliliters of 11 percent concentrated acid and 10 milliliters of 2 percent concentrated acid.

Step-by-step explanation:

Given that a researcher wants a 30 milliliter acid solution with a concentration of 8%, and she has concentrations of 2% and 11%, to determine how much of each solution must she use to get the desired concentration, the following calculation must be performed:

100 x 0.11 + 0 x 0.02 = 11

90 x 0.11 + 10 x 0.02 = 10.1

80 x 0.11 + 20 x 0.02 = 9.2

70 x 0.11 + 30 x 0.02 = 8.3

66.666 x 0.11 + 33.333 x 0.02 = 8

30 x 0.6666 = 20

Therefore, the researcher needs 20 milliliters of 11 percent concentrated acid and 10 milliliters of 2 percent concentrated acid.

Answer:

0.9544 = 95.44% probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Suppose the mean fill for the shipment is actually 50 gallons. Standard deviation of 0.6 gallons.

This means that [tex]\mu = 50, \sigma = 0.6[/tex]

Sample of 100:

This means that [tex]n = 100, s = \frac{0.6}{\sqrt{100}} = 0.06[/tex]

What is the probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons?

This is the pvalue of Z when X = 50.12 subtracted by the pvalue of Z when X = 49.88. So

X = 50.12

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{50.12 - 50}{0.06}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772

X = 49.88

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{49.88 - 50}{0.06}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

0.9772 - 0.0228 = 0.9544

0.9544 = 95.44% probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons.

Answer:

72.2566311

Step-by-step explanation:

Circumference = 2πr

We don't have the radius, but we do know that half of the diameter is the radius, so 23/2 = 11.5. r = 11.5

Now, plug the radius into the equation:

2π(11.5)

Solve:

2π(11.5) = 72.2566311

Answer:

It can't

Step-by-step explanation:

I cannot represent values of a funcion because if you convert all the sets into fractions, (if simplified) then they will not be the same fraction. This is needed if you want a function that works.

The fractions are: 1/7, 3/16, 5/19, 1/4, 9/28. if simplified, then these are different fractions.

Additionally, you can see that it has both 5/19 and 5/20. (1/4).

If this was a working function it would yield the same output every time you put in 5 as an input.

Therefore, it cannot represent a function.

Answer:

the answer is c 50x +11

Step-by-step explanation:

The Perimeter of the model is (50x + 11).

A shape's perimeter is calculated mathematically using the idea of perimeter. You sum together the lengths of all the sides to find the perimeter.

We have,

The two sides of the triangle are 6x - 4 units each.

The length of the rectangle is 14x + 13.

The width of the rectangle is 12x + 3.

So, the perimeter of the house

= (6x -4) + (14x + 13) + (12x + 3) + 12x + 3 + 6x -4

= 50x + 11

Thus, the perimeter is 50x + 11.
