Answer:

The sample mean used for this interval is 1750.

The sample standard deviation used for this interval was of 175.34

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The margin of error is the subtraction of these two bounds divided by two.

In this question:

Lower bound: 1690

Upper bound: 1810

Sample mean

[tex]\frac{1690 + 1810}{2} = 1750[/tex]

The sample mean used for this interval is 1750.

Sample standard deviation:

The first step is finding the margin of error:

[tex]M = \frac{1810 - 1690}{2} = 60[/tex]

Now we have to develop the problem a bit.

We want the sample standard deviation, so we use the T-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.711

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

We have that: [tex]M = 60, T = 1.711, n = 25[/tex]

We have to find s

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

[tex]60 = 1.711\frac{s}{\sqrt{25}}[/tex]

[tex]1.711s = 60*5[/tex]

[tex]s = \frac{60*5}{1.711}[/tex]

[tex]s = 175.34[/tex]

The sample standard deviation used for this interval was of 175.34

The probability of the pumping system failing on any given day is 0.015, or 1.5 percent.

Given data:

To find the probability that the pumping system will fail on any given day,  consider the probabilities of different failure scenarios for the two pumps.

Let's denote the events as follows:

A = Only the older pump fails

B = Only the newer pump fails

P(A) = 0.15 (probability that only the older pump fails)

P(B) = 0.10 (probability that only the newer pump fails)

To find the probability that both pumps fail, which can be denoted as the event A ∩ B.

Since the two pumps fail independently of each other, use the multiplication rule for independent events to calculate the probability of both events occurring:

P(A ∩ B) = P(A) * P(B)

Substituting the given probabilities:

P(A ∩ B) = 0.15 * 0.10

= 0.015

Hence, the probability that the pumping system will fail on any given day (when both pumps fail) is 0.015 or 1.5%.

Answer:

The lines will intersect infinitely many times, because they are identical.

Step-by-step explanation:

Let's change the equations of the lines into (y=mx+b) form.

6x-4y=2 Divide by 2.

3x-2y=1 Move x and divide by -2.

-2y=1-3x ---> y= -1/2+3/2x

The equation of the first line is y=3/2x- 1/2

-2y+3x=1

-2y=1-3x

y = 3/2x -1/2

The equation of the second line is y = 3/2x- 1/2.

The lines are identical- infinitely many intersections.

Answer:

As per the properties of parallel lines and interior alternate angles postulate, we can prove that:

[tex]m\angle 5+m\angle 2+m\angle 6=180^\circ[/tex]

Step-by-step explanation:

Given:

Line y || z

i.e. y is parallel to z.

To Prove:

[tex]m\angle 5+m\angle 2+m\angle 6=180^\circ[/tex]

Solution:

It is given that the lines y and z are parallel to each other.

[tex]m\angle 5, m\angle 1[/tex] are interior alternate angles because lines y and z are parallel and one line AC cuts them.

So, [tex]m\angle 5= m\angle 1[/tex] ..... (1)

Similarly,

[tex]m\angle 6, m\angle 3[/tex] are interior alternate angles because lines y and z are parallel and one line AB cuts them.

So, [tex]m\angle 6= m\angle 3[/tex] ...... (2)

Now, we know that the line y is a straight line and A is one point on it.

Sum of all the angles on one side of a line on a point is always equal to [tex]180^\circ[/tex].

i.e.

[tex]m\angle 1+m\angle 2+m\angle 3=180^\circ[/tex]

Using equations (1) and (2):

We can see that:

[tex]m\angle 5+m\angle 2+m\angle 6=180^\circ[/tex]

Hence proved.

Answer: yes

Step-by-step explanation: yes

Answer:

Yes, the function satisfies the hypothesis of the Mean Value Theorem on the interval [1,5]

Step-by-step explanation:

We are given that a function

[tex]f(x)=ln(x)[/tex]

Interval [1,5]

The given function is defined on this interval.

Hypothesis of Mean Value Theorem:

(1) Function is continuous on interval [a,b]

(2)Function is defined on interval (a,b)

From the graph we can see that

The function is continuous on [1,5] and differentiable at(1,5).

Hence, the function satisfies the hypothesis of the Mean Value Theorem.

Answer:

Yes. At a significance level of 0.05, there is enough evidence to support the claim that the fish in all Florida lakes have different mercury than the allowable amount.

The random variable is the sample mean amount of mercury in the bass fish from the lakes of Florida.

The population parameter is the mean amount of mercury in the bass fish of Florida lakes.

The alternative hypothesis (Ha) states that the amount of mercury significantly differs from 1 mg/kg.

The null hypothesis (H0) states that the amount of mercury is not significantly different from 1 mg/kg.

[tex]H_0: \mu=1\\\\H_a:\mu\neq 1[/tex]

Step-by-step explanation:

The question is incomplete.

There is no data provided.

We will work with a sample mean of 0.95 mg/kg and sample standard deviation of 0.15 mg/kg to show the procedure.

This is a hypothesis test for the population mean.

The claim is that the fish in all Florida lakes have different mercury than the allowable amount (1 mg of mercury per kg of fish).

Then, the null and alternative hypothesis are:

[tex]H_0: \mu=1\\\\H_a:\mu\neq 1[/tex]

The significance level is assumed to be 0.05.

The sample has a size n=53.

The sample mean is M=0.95.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=0.15.

The estimated standard error of the mean is computed using the formula:

[tex]s_M=\dfrac{s}{\sqrt{n}}=\dfrac{0.15}{\sqrt{53}}=0.0206[/tex]

Then, we can calculate the t-statistic as:

[tex]t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{0.95-1}{0.0206}=\dfrac{-0.05}{0.0206}=-2.427[/tex]

The degrees of freedom for this sample size are:

[tex]df=n-1=53-1=52[/tex]

This test is a two-tailed test, with 52 degrees of freedom and t=-2.427, so the P-value for this test is calculated as (using a t-table):

[tex]\text{P-value}=2\cdot P(t<-2.427)=0.019[/tex]

As the P-value (0.019) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

At a significance level of 0.05, there is enough evidence to support the claim that the fish in all Florida lakes have different mercury than the allowable amount.

[tex]f(x) = [\frac{t^{4} }{4} + 2t^{2}-2t]\left \ {t =x} \atop {t=2}} \right.\\when\ t = x\\f(x) = \frac{x^{4} }{4} + 2x^{2}-2x\\\\[/tex]

[tex]when\ t = 2;\\f(2) = \frac{2^{4} }{4} + 8-4\\f(2) = 8\\[/tex]

[tex]f(x) - f(2) = \frac{x^{4} }{4} + 2x^{2}-2x -8\\\\at\ x =2; f(x) = \frac{2^{4} }{4} + 8-4 -8 =0\\\\at\ x =4; f(x) = \frac{4^{4} }{4} + 32-8 -8 =80\\\\at x = 8; f(x) = \frac{8^{4} }{4} + 4(8^{2})-16 -8 =1256[/tex]

Answer:

6.10%

Step-by-step explanation:

For every round since we are choosing with equal probability, then the probability of choosing from either of the bags is 1/2

Here, this scenario is only possible when a particular bag has been chosen 10 times and the other bag has been chosen 6 times ( meaning a particular bag has been emptied and for a particular bag to be emptied, all of its content would have been picked)

Now on the 17th trial, an empty bag is chosen

Therefore the required probability will be;

16C0 * (1/2)^10 * (1/2)^6 * 1/2 = 0.0610 = 6.1%

Answer:

Millennium Dairy Product

a) Share of the company that SBI Caps should require today to get a required rate of return of 50%.

= 50%

b) If the company had 1,000,000 (100,000 x10) shares outstanding before the private placement, SBI Caps should purchase

1,000,000 shares = 50% of (1,000,000 + 1,000,000) shares

Assuming the founding promoters are not giving up their shares, instead, new equity shares are being issued.

c) The price per share SBI Caps should agree to pay, if her required return was 50% is

Rs.50 per share, which will provide the required additional equity financing of (Rs.50 million) since Rs.50 x 1,000,000 equals Rs.50 million.

d) Pre money and post money valuations:

These are based on the calculated Market Price of Rs.1,000 per share from the Price/Earnings Ratio.

Pre money valuation will be Rs.1,000 x 1,000,000 shares = Rs.1 billion

Post money valuation will be Rs.1,000 x 2,000,000 shares = Rs.2 billion

e) Carried interests of the VC and the promoters

VC's carried interest = share of profits = 50% xRs.50 million = Rs.25 million

Promoters' carried interest = Rs.25 million

Step-by-step explanation:

a) Calculation of share in the company:

SBI Cap's required rate of return is 50%

If she invests Rs.50 million today, her expected return will be equal to Rs.50 million x 50% = Rs.25 million

Since rate of return = Net Income/Initial Investment or (Current value of investment - Initial Investment)/Initial Investment.

This return will be equal to 50% of the total net income of Rs.50 million

b) Price/Earnings P/E ratio = Market price per share/Earnings per share (EPS)

Since P/E ratio of similar companies = 20 times,

The company's P/E = 20 times x EPS

With calculated EPS = Rs.50 million /1,000,000 = Rs.50

Therefore, price per share = 20 x Rs.50 = Rs.1,000

Pre money valuation = Rs.1,000 x 1 million shares = Rs.1 billion

Post money valuation = Rs.1,000 x 2 million shares = Rs.2 billion

c) The carried interest is the share of profits to which the promoters and the Venture Capitalists are entitled.  Their respective shares are 50% of the net income = Rs.25 million each.

d) The pre money and post money valuations:  The pre money valuation is the valuation of the company before the additional equity financing.  The post money valuation is the valuation of the company after the additional equity financing.  There are many ways to value a company.  In this case, we have used the P/E ratio as a basis for the valuation.  However, we did not dilute the earnings per share post money, for simplicity.

(0,0)

Explanation:

The rule you use is [tex](x,y) \to (-x,-y)[/tex] when it comes to 180 degree rotations (either clockwise or anticlockwise/counterclockwise). So we flip the signs of the x and y coordinates. Any point on an axis will stay on the same axis. The origin is the intersection of the two axes, so this point does not move at all. We call this point fixed or stationary. The fixed point is one where every point rotates around it.

Answer:

r = 14

Step-by-step explanation:

We need to divide the equation by 13 so that we get just n one one side without any coefficients. Doing so we get r = 182 / 13 = 14.

Answer:

r = 14

Step-by-step explanation:

Well to find r we need to get it by itself and to do that we get rid of 13.

And to get rid of 14 we do 13r/13 and 182/13.

So 13r / 13 is r and 182/13 is 14.

So r = 14.

Find:

  (i) Homes completed in 12 months through Jan 2011

  (ii) Comparison to homes started in 2010

Solution:

(i) Using the given relation, we can find homes completed through Jan 2011.

  281,000 = 0.663×completed

  completed = 281,000/0.663 = 423,831

(ii) Similarly, we can find the number of 2010 starts:

  starts(1 -28.5%) = 378,000

  starts = 378,000/0.715 = 528,671

The relation of completions in 2011 to starts in 2010 is ...

  423,831 -528,671 = -104,840

Answer:  Sheila today = [tex]46\dfrac{1}{3}[/tex]  yrs old

Step-by-step explanation:

   J + S = 115 v⇒  J = 115 - S

Current Ages                        Ages 14 years ago

 Joe (J) = 115 - S                      J - 14 = 2(S - 14)

 Sheila (S) = S

Substitute J = 115 - S into the "14 years ago" equation

      J    - 14 = 2(S - 14)

(115 - S) - 14 = 2(S - 14)

111 -S = 2S - 28

111 = 3S  - 28

139 = 3S

46 [tex]\frac{1}{3}[/tex] = S

It is odd that the result was not an integer.  I wonder if you meant to type "Joe was twice as old as Sheila is today.  That would change the equation to:
