You are the only bidder in an online auction of a nintendo wii system with games and accessories. The seller has set a secret reserve price (the minimum price she is willing to accept for the wii). Assume that the secret reserve price x is uniformally distributed between $240 and $320.1) Height of the probability density function f(x) varies with x as follows (round to four decimal places). 240 ≥ x ≥ 3202) You enter a bid of $280 for the wii. What is the probability that you'll win the auction?3) What is the mean secret reserve price?4) What is the standard deviation of the above question?5) You enter your bid of $280 and see that the seller's reserve price has not been met. You enter a new bit of $300. Now what is the probability that you'll win the auction?

Answer:

..............................what this

Answer:

It Is true and then false

Step-by-step explanation:

Probability is expressed as

number of favorable outcomes/number of total outcomes

In a standard deck of cards, the total number of cards is 52.

There are 13 spades in a standard deck. Thus,

probability of selecting a spade = 13/52 = 1/4

There are 26 red cards in a standard deck of cards. Since the first card was replaced, the total number of cards remains 52.

probability of selecting a red card = 26/52 = 1/2

There are 4 queens in a standard deck of cards. Since the second card was also replaced, total number of cards is still 52. Thus,

Probability of selecting a queen = 4/52 = 1/13

Thus, the probability that the first card will be a spade, the second card will be a red card, and the third card will be a queen is

1/4 x 1/2 x 1/13

= 1/104

Answer:

19.99

Step-by-step explanation:

First you would multiply .44 by 16 to get 7.04

then you would add 12.95 to get 19.99

This question is about how transformations can affect graphs.

First, we'll want to get rid of that -4 on the function of F.

So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph \(x^2\).

Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.

Finally, we can move the function of by \(\frac{2}{3}\) because the d value is positive, meaning that we move the graph up.

Hope this helps.

Step-by-step explanation:

1/16 for Washington County.

5/76 for Webster County.

so, let's bring both to the same denominator (bottom part of the fractions).

this is usual the LCM of both denominators.

since 16 = 2×2×2×2

76 = 2×2×19

the least common multiple (LCM) is the combination of the longest sequence per prime factor involved :

2×2×2×2×19 = 16×19 = 304

1/16 = 19/304

5/76 = 5× 1/76 = 5× 4/304 = 20/304

so, now we know, 20/304 > 19/304, and therefore Webster County has the greater fraction of adults, who enjoy gardening.

Answer:

Take 2x- 3y= 6 as equation 1

And

x+ 3y= 3 as equation 2

Now add both equation

2x - 3y = 6

x + 3y = 3

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

3x 0 = 9

We can also write 3x 0= 9 as 3x = 9

Now we have to solve 3x =9

3x = 9

x = 9/3

x= 3

  sin(38°) = x/8.2

  x = 8.2·sin(38°) ≈ 5.048

a. The proposition becomes: true V false = true So, the proposition is true.

b. The proposition becomes: true V true = true So, the proposition is true.

c. The proposition becomes: true Λ true = true So, the proposition is true.

Recall that the truth values of compound propositions depend on the truth values of their component propositions and the logical connectives used.

Given that p is false, q is true, and r is false, we can determine the truth value of each of the propositions below:

a. ┐p V ┐q

Using the truth values of p and q, we have:

┐p = true

┐q = false

Therefore, the proposition becomes:

true V false = true

So, the proposition is true.

b. ┐p V ┐(qΛ r)

Using the truth values of p, q, and r, we have:

qΛ r = false (since r is false)

┐(qΛ r) = true

┐p = true

Therefore, the proposition becomes:

true V true = true

So, the proposition is true.

c. (pV┐r) Λ ((q V r) V ┐(r V p))

Using the truth values of p, q, and r, we have:

pV┐r = true

r V p = true

┐(r V p) = false

q V r = true

Therefore, the proposition becomes:

true Λ true = true

So, the proposition is true.

Step-by-step explanation:

Answer:

i \(\to\) a

    \(n = 96040000\)

i \(\to\) b

    \(n_1 =24010000\)

i \(\to\) c

    \(n_2 =41602500\)

ii\(\to\)c

    There is insufficient evidence to conclude that the analyst is right because the population mean fee by the analyst does not fall within the confidence interval

Step-by-step explanation:

From the question we are told that

     The sample size is \(n = 8\)

      The sample mean is  \(\= x = \$ 350\)    

      The sample standard deviation is  \(\$ 100\)

Considering question i

    i \(\to\) a

         At   \(E = 0.02\)  

given that the confidence level is 95%  =  0.95

         the level of significance would be  \(\alpha =1-0.95 = 0.05\)

The critical value of  \(\frac{\alpha }{2}\) from the normal distribution table is  

        \(Z_{\frac{ \alpha }{2} } = 1.96\)

So  the sample size is mathematically evaluated as

            \(n = [ \frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ]^2\)

=>        \(n =[ \frac{ 1.96 * 100}{ 0.02} ]^2\)

=>         \(n = 96040000\)

 i \(\to\) b

  At  \(E_1 = 0.04\)    and  confidence level  = 95%  =>  \(\alpha_1 = 0.05\)   =>  \(Z_{\frac{\alpha_1 }{2} } = 1.96\)

             \(n_1 = [ \frac{Z_{\frac{\alpha_2 }{2} } * \sigma }{E_1} ]^2\)

=>           \(n_1 =[ \frac{ 1.96 * 100}{ 0.04} ]^2\)

=>           \(n_1 =24010000\)

 i \(\to\) c

       At   \(E_2 = 0.04\)     confidence level  = 99%  =>    \(\alpha_2 = 0.01\)

The critical value of  \(\frac{\alpha_2 }{2}\) from the normal distribution table is  

        \(Z_{\frac{ \alpha_2 }{2} } = 2.58\)

=>    \(n_2 = [ \frac{Z_{\frac{\alpha_2 }{2} } * \sigma }{E_2} ]^2\)

=>    \(n_2 =[ \frac{ 2.58 * 100}{ 0.04} ]^2\)

=>    \(n_2 =41602500\)

Considering ii

Given that the level of significance is  \(\alpha = 0.10\)

Then the critical value  of  \(\frac{\alpha }{2}\) from the normal distribution table is  

           \(Z_{\frac{\alpha }{2} } = 1.645\)

Generally the margin of error is mathematically represented as

          \(E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }\)

substituting values

         \(E = 1.645 * \frac{100 }{\sqrt{8} }\)

         \(E = 58.16\)

Generally the 90% confidence interval is mathematically evaluated as

         \(\= x - E < \mu < \= x + E\)

=>      \(350 - 58.16 < \mu < 350 + 58.16\)

=>     \(291.84 < \mu < 408.16\)

So the interpretation is that there is 90% confidence that the mean  fee charged to H&R Block customers last year is in the interval .So there is insufficient evidence to conclude that the analyst is right because the population mean fee by the analyst does not fall within the confidence interval.

Answer:

A = 22.62°

B = 67.38°

c = 26

Step-by-step explanation:

\(a^2+b^2=c^2\\10^2+24^2=c^2\\100+576=c^2\\676=c^2\\26=c\)

\(\sin A=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{10}{26}\\\\A=\sin^{-1}(\frac{10}{26})\\\\A\approx22.62^\circ\)<-- You can also use other trig ratios

\(B=180^\circ-(90^\circ+22.62^\circ)=180^\circ-112.62^\circ=67.38^\circ\)

There's no specific order in how to solve for A and B, so there may be more than one way to approach these solutions.

Answer:

Step-by-step explanation:

x² + 3x - 70 = 0

x² + 3x = 70

x² + 3x + (3/2)² = 70 + (3/2)²

(x + 3/2)² = 70 + 9/4 = 289/4 = (17/2)²

so

x + 3/2 = ±17/2

x = ±17/2 - 3/2

x₁ = 17/2 - 3/2 = 14/2 = 7

x₂ = -17/2 - 3/2 = -20/2 = -10

x² = -10x - 30

x² + 10x = -30

x² + 10x + (10/2)² = -30 + (10/2)²

x² + 10x + 25 = -30 + 25 = -5

(x + 5)² = -5

\(x+5 = \pm\sqrt{-5}\\x + 5 = \pm i \sqrt{5}\\x = -5\pm i \sqrt{5}\\\\x_1 = -5+ i \sqrt{5}\\\\x _2= -5- i \sqrt{5}\\\)

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

3y = -6x + 9

y = -2x + 3.

Simplify the equation 3y = -6x + 9.

So equation 3y = -6x + 9 is equal to y = -2x + 3. The equation has same slope and y intercept. Thus lines lie on each other on the graph and have infinite many solution.
