Answer:

You should expect her to be wrong 32 times.

Step-by-step explanation:

For each forecast that she makes, there are only two possible outcomes. Either she is correct, or she is not. The probability of she being correct on a forecast is independent of other forecasts. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

\(E(X) = np\)

0.8 chance of being correct.

So 1 - 0.8 = 0.2 change of being wrong, which means that \(p = 0.2\)

160 forecasts:

This means that \(n = 160\)

How many of these times would you expect she is wrong?

\(E(X) = np = 160*0.2 = 32\)

You should expect her to be wrong 32 times.

The critical points of the function are (0, 0) and (3/4, -9/4), To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point

To find the critical points of the function f(x, y) = 8x^3 + y^2 + 6xy, we need to find the values of (x, y) where the partial derivatives with respect to x and y are equal to zero.

Taking the partial derivative with respect to x, we have:

∂f/∂x = 24x^2 + 6y = 0.

Taking the partial derivative with respect to y, we have:

∂f/∂y = 2y + 6x = 0.

Solving these two equations simultaneously, we get:

24x^2 + 6y = 0,

2y + 6x = 0.

From the second equation, we can solve for y in terms of x:

Y = -3x.

Substituting this into the first equation:

24x^2 + 6(-3x) = 0,

24x^2 – 18x = 0,

6x(4x – 3) = 0.

Therefore, we have two possibilities for x:

1. x = 0,

2. 4x – 3 = 0, which gives x = ¾.

Substituting these values back into y = -3x, we get the corresponding y-values:

1. x = 0 ⇒ y = 0,

2. x = ¾ ⇒ y = -9/4.

Hence, the critical points of the function are (0, 0) and (3/4, -9/4).

To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point. However, since the original function does not provide any information about the second partial derivatives, further analysis is required to classify the critical points.

Step-by-step explanation:

Answer:

-11

Step-by-step explanation:

-1/2y=1/2+5

- 1/2 y = 1+10 (by taking lcm)

               2  

 \(\frac{-1}{2}\) x 2y = 11

y = -11

\( \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5\)

\( \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5\)

\( \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} \)

\(y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} \)

\(y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} \)

\(y = \frac{ \: \: 22}{ - 2} \)

\(y = - 11\)

The value of y = -11

Answer:

152 ft²

Step-by-step explanation:

First, we can work out the area of the triangles using the formula 1/2 × base × height. 1/2 × 6 × 4 = 12 ft². This is the area of one triangle so we can multiply this by 2 to get the area of both triangles - 24ft².

Next, we can work out the area of the rectangular sides by multiplying the length and width together. 8 × 5 = 40ft². Again, this is the area of one rectangle so we can multiply this by 2 to get the area of both rectangles - 80ft².

Then, we can work out the area of the base by multiplying the length and width together. 8 × 6 = 48ft².

Finally, we can add all the areas together to find the total surface area of the tent. 24 + 80 + 48 = 152 ft².

Answer:

77 degrees

Step-by-step explanation:

Right triangles always add up to 180 degrees. We know that one angle is 23 degrees, angle A is missing, and the last angle is a right angle which is equal to 90 degrees. Knowing what we know, we must subtract the two known angles from 180 to get angle A.

180 - 90 = 90

90 - 23 = 77

Angle A is equal to 77 degrees.

There are 380 Roman coins in the museum's collection, calculated by adding the number of coins indicated by each bin in the histogram (126 + 102 + 78 + 54 + 20 = 380).

The histogram displays the masses of all of the coins in a museum's collection, with each bin representing a different mass range. The first bin, containing 126 coins, indicates that the coins weigh between 8g and 17g. To work out how many coins are in the museum's collection in total, we need to add the number of coins in each bin.

Starting with the first bin, there are 126 coins. The second bin indicates that there are 102 coins weighing between 18g and 27g, the third bin indicates that there are 78 coins weighing between 28g and 37g, the fourth bin indicates that there are 54 coins weighing between 38g and 47g, and finally the fifth bin indicates that there are 20 coins weighing between 48g and 57g.Therefore, to find the total number of coins in the museum's collection, we need to add all of these numbers together:

126 + 102 + 78 + 54 + 20 = 380

Therefore, there are 380 Roman coins in the museum's collection.

By applying probability method in a Poisson distribution, we find out that the probability that in a given year that area will be hit by fewer than 4 hurricanes is 0.1512 and the probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes is 0.4015.

It is given that -

On an average, Eastern United States is hit by 6 hurricanes in a year.

We have to find out -

(a) Probability that in a given year that area will be hit by fewer than 4 hurricanes

(b) Probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes

This is a case of probability which relates to Poisson distribution that provides probability of any random event that occurs within a specific time interval.

Let us assume the number of hurricanes is represented by \(X\). The Poisson distribution can be represented as -

\(P(X) = \frac{(lambda)^{X}*e^{-lambda}}{X!}\) -------(1)

​Here, \(X\\\) = 1,2,3,...

lambda = Average = 6 (in this question)

\(e\) = 2.718

(a) Probability that in a given year that area will be hit by fewer than 4 hurricanes

\(P(X < 4) = P(X=0) +P(X=1)+P(X=2)+P(X=3)\\= \frac{6^{0}*e^{-6}}{0!}+\frac{6^{1}*e^{-6}}{1!}+\frac{6^{2}*e^{-6}}{2!}+\frac{6^{3}*e^{-6}}{3!}\\=0.0025+0.0149+0.0446+0.0892\\=0.1512\)

Thus, the probability that in a given year that area will be hit by fewer than 4 hurricanes is 0.1512.

(b) Probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes

\(P(6\leq X\leq 8)=P(X=6)+P(X=7)+P(X=8)\\=\frac{6^{6}*e^{-6} }{6!}+\frac{6^{7}*e^{-6} }{7!}+\frac{6^{8}*e^{-6} }{8!}\\=0.1606+0.1376+0.1033\\=0.4015\)

Thus, the probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes is 0.4015.
