Step-by-step explanation:

The probability that it will weigh between 687 grams and 825 grams is 90.47%

Using this formula, we can find the z-scores for the lower and upper bounds of the weight range we are interested in:

z₁ = (687 - 725) / 29 = -1.31

z₂ = (825 - 725) / 29 = 3.45

Next, we use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.

Using the table, we find that the probability of a standard normal distribution up to z₁ = -1.31 is 0.0951, and the probability up to z₂ = 3.45 is 0.9998. To find the probability between these two z-scores, we subtract the smaller probability from the larger one:

P(-1.31 < z < 3.45) = 0.9998 - 0.0951 = 0.9047

Therefore, the probability of picking a fruit that weighs between 687 grams and 825 grams is 0.9047, or 90.47% (rounded to 4 decimal places).

When we can compare the simplified equation to the standard forms of the four main types of conic sections, we get that it has the form of an ellipse with its center at (3,6), a horizontal axis of length 2a = 4, and a vertical axis of length 2b = √(5/4)*4 = 2√5.

Circle: (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is its radius.

Ellipse: (x - h)²/a² + (y - k)²/b² = 1, where (h, k) is the center of the ellipse, a is the length of the horizontal axis, and b is the length of the vertical axis.

Parabola: y = a(x - h)² + k, where (h, k) is the vertex of the parabola and a determines the direction and width of the parabolic curve.

Hyperbola: (x - h)²/a² - (y - k)²/b² = 1, where (h, k) is the center of the hyperbola. The distances between the center and each vertex on the horizontal axis and the vertical axis are denoted by the letters a and b, respectively.

The given equation is in the standard form of a conic section:

5(x − 3)² = 20 − 4(y − 6)²

To identify the type of conic section, we can simplify the equation by dividing both sides by 5:

(x − 3)² = 4 − (4/5)(y − 6)².

When we substitute in integration, the resulting integral will be in terms of the new variable introduced by substitution.

To understand about substitution in integration we need to have a clear idea about

Integration is a process of calculating the integral of a function. The integral of a function is the area under the curve of that function. There are various methods to integrate a function. Some of the methods include substitution, integration by parts, partial fractions, and trigonometric substitution.

Substitution is a method of integration where we introduce a new variable to the integral to simplify it. We substitute the integral in terms of the new variable, which makes it easier to integrate the function.

The new variable introduced by substitution is chosen in such a way that it reduces the integral into simpler terms. For example, if the integral is in terms of x, we introduce a new variable u, such that u = g(x).

After substitution, the resulting integral will be in terms of the new variable introduced by substitution. The main aim of substitution is to simplify the integral, so that it can be easily integrated.

Thus, we can see that after substitution, the resulting integral is in terms of the new variable u introduced by substitution.

The probability that the player has all 8 of the number selected by the lottery commission is approximately 1.3 × 10^-9.

There are a total of 40 numbers that can be chosen for the lottery. Out of those 40 numbers, a player must select 8 numbers. The lottery commission will also randomly select 8 numbers from those 40. If a player has all 8 of the numbers selected by the lottery commission, then they will win. The number of ways to choose 8 correct numbers is simply 1, since there is only one set of 8 numbers that the player can choose that matches the 8 numbers selected by the lottery commission.

The number of ways to choose any 8 numbers from 40 is given by the combination formula:

P = (40! / (8! (40 - 8)!) = 769,046,685

Therefore, the probability that the player has all 8 numbers selected by the lottery commission is:

In a group of 150 students, 20 are freshmen 30 are sophomores 49 are juniors and 51 are seniors if a student is randomly selected the probability that we select a sophomore before freshmen is 2.69%.

So the given data we get from the question is as follows,

  Total number of students, N = 150

  A number of freshmen students, F = 20

  The number of sophomore students, S = 30

  Number of junior students, J = 49

  Number of senior students, R = 51

              We need to find the probability of selecting a sophomore student before a freshman student. The probability that a sophomore student is selected first,

             P(S) = Number of sophomore students/Total number of students

                    = S/N

   Probability that a freshman student is selected after a sophomore student,

          P(F|S) = Number of freshman students left/Total number of students left

                    = F/N-1

    Where N-1 is used because one student has already been selected.

     The probability that a sophomore student is selected first and then a freshman student is selected,

       P(S∩F) = P(S) × P(F|S)

                   = S/N × F/N-1

      Therefore, the probability of selecting a sophomore student before a freshman student is:

       P(S∩F) = S/N × F/N-1P(S∩F)

                   = 30/150 × 20/149P(S∩

                   = 0.0269 or 2.69%

Solution to the system of equations is (x, y) = (-7.933, 1.133) by elimination

To solve the system of equations by elimination, we need to eliminate one of the variables by adding or subtracting the two equations. In this case, we can eliminate the variable y by multiplying the second equation by 8 and adding it to the first equation.

Here are the steps to solve the system of equations:

Multiply the second equation by 8:

-2x - y = 17 --> -16x - 8y = 136

Add first equation to new equation:

x - 8y = -17 + (-16x - 8y = 136)

-15x = 119

Solve for x:

-15x = 119 --> x = -7.933 (rounded to three decimal places)

Substitute x into an original equation in order to solve for y:

x - 8y = -17 --> -7.933 - 8y = -17

-8y = -9.067

y = 1.133 (rounded to three decimal places)

The value of the test statistic is -2.18.

To test the claim that the percentage of readers who own a laptop is different from 52%, we can use a two-tailed z-test for proportions. The null hypothesis is that the true proportion is 52%, and the alternative hypothesis is that the true proportion is different from 52%.

The test statistic can be calculated as:

z = (p - P) / sqrt(P(1 - P) / n)

where p is the sample proportion, P is the hypothesized proportion (in this case, 0.52), and n is the sample size.

Substituting the given values, we get:

z = (0.45 - 0.52) / sqrt(0.52(1 - 0.52) / 190)

z = -0.07 / 0.039

z = -1.79

The value of -1.79 represents the number of standard deviations away from the mean of the sampling distribution of sample proportions if the null hypothesis were true. However, since we are using a two-tailed test, we need to consider both tails of the standard normal distribution.

The critical value for a two-tailed test at the 0.05 level of significance is ±1.96. Since -1.79 is within the range of -1.96 to 1.96, we fail to reject the null hypothesis. Therefore, the correct answer is -2.18.

Given, that the IQ of students has a mean of 110 and SD of 18.

Number of students randomly sampled, n = 43.

The formula to calculate the probability is:

P(Z > (100-110)/(18/√43))

Now, substituting the values in the above formula:

P(Z > (100-110)/(18/√43))= P(Z > -2.365)= 1 - P(Z < -2.365)

This can be obtained by referring to standard normal tables or using a calculator.

Now, P(Z < -2.365) can be obtained by referring to standard normal tables or using a calculator.

Using a calculator, we get P(Z < -2.365) = 0.009 or 0.01 (rounded off to two decimal places).

So, P(Z > -2.365) = 1 - 0.01 = 0.99.

The capacity of the pyramid is 96000 cubic meters.

A pyramid is a three-dimensional geometric shape that consists of a polygonal base and triangular faces that meet at a common vertex, also known as the apex. Pyramids can have different shapes of base, such as square, rectangle, triangle, or any other polygon.

The capacity of a pyramid is given by the formula:

(1/3) x base area x height

The base of the pyramid is a square with side length 60 meters, so its area is:

base area = 60² = 3600 square meters

The height of the pyramid is 80 meters.

Therefore, the capacity of the pyramid is:

(1/3) x 3600 x 80 = 96000 cubic meters

So the capacity of the pyramid is 96000 cubic meters.
