Step-by-step explanation:

The other characteristic of a discrete probability distribution function is that each individual outcome has a probability greater than or equal to zero.

In other words, the probability assigned to each possible value in the distribution must be non-negative. This ensures that the probabilities are valid and that the distribution accurately represents the likelihood of each outcome occurring. So, the two characteristics of a discrete probability distribution function are: (1) the sum of the probabilities is one, and (2) each individual outcome has a probability greater than or equal to zero.

The sum of the series 9+10+11+12+4+1+490 is equal to 84. The sum of the series 0+10+11+12+11+k is represented by the expression 3 + k.

(a) To evaluate the sum of the given series 9+10+11+12+4+1+490, we can use the formula for the sum of an arithmetic series. The formula is:

Sn = (n/2) * (2a + (n-1)d)

where Sn represents the sum of the series, n is the number of terms, a is the first term, and d is the common difference between terms.

In this case, we have:

n = 7 (since there are 7 terms)

a = 9 (the first term)

d = 1 (since each term increases by 1)

Substituting these values into the formula, we get:

Sn = (7/2) * (2*9 + (7-1)*1)

  = (7/2) * (18 + 6)

  = (7/2) * 24

  = 7 * 12

  = 84

Therefore, the sum of the series 9+10+11+12+4+1+490 is 84.

By applying the formula for the sum of an arithmetic series, we determined that the sum of the given series is 84.

(b) To express the sum 0+10+11+12+11+k in closed form, we need to identify the pattern and the number of terms in the series. The pattern shows that the terms are increasing by 1, except for the last term, which involves an unknown value represented by 'k'.

The series consists of four terms with a common difference of 1, followed by the last term involving 'k'. To express it in closed form, we'll use the formula for the sum of an arithmetic series:

Sn = (n/2) * (2a + (n-1)d)

In this case, we have:

n = 4 (since there are four terms before 'k')

a = 0 (the first term)

d = 1 (since each term increases by 1)

Applying the formula, we get:

Sn = (4/2) * (2*0 + (4-1)*1)

  = (2/2) * (0 + 3)

  = 1 * 3

  = 3

So, the sum of the terms 0+10+11+12 is 3.

To express the sum in closed form, we add the last term 'k' to the sum:

Sum = 3 + k

Answer: (-.5, .5)

Step-by-step explanation:

Answer:

about 169.65

Step-by-step explanation:

The formula for the volume of a cylinder is \(\pi r^2h\).

All you have to do is plug the numbers in.

\(V=\pi (3)^2(6)\)

Then use a calculator to evaluate.

The volume of the cylinder is approximately 169.56 cubic units.

The formula for the volume of a cylinder is:

V = πr^2h

where V is the volume, r is the radius of the base, and h is the height.

Substituting the given values, we get:

V = π(3)^2(6)

V = π(9)(6)

V = 54π

Therefore, the volume of the cylinder is 54π cubic units. If you need an approximate numerical value, you can use the approximation 3.14 for π and calculate:

V ≈ 54 x 3.14

Fraction of the chocolates in the box that are dark chocolate and filled with caramel is 3/32.

To solve this problem, we need to determine what fraction of chocolates in the box are both dark chocolate and filled with caramel. We are given that:

Three-fourths of the chocolates in a box are dark chocolate. Three-eighths of the dark chocolates are filled with caramel. We need to find out the fraction of chocolates that are dark chocolate and filled with caramel. To find out the fraction of chocolates in the box that are dark chocolate, we divide the number of dark chocolates by the total number of chocolates.

This is given by:

3/4 (dark chocolates)

To find the fraction of dark chocolates that are filled with caramel, we multiply the fraction of dark chocolates by the fraction of dark chocolates filled with caramel. This is given by:

3/4 × 3/8 = 9/32

Therefore, the fraction of chocolates in the box that are dark chocolate and filled with caramel is 9/32.

To simplify the fraction 9/32, we can divide the numerator and denominator by their                                             greatest common factor, which is 1:9/32 = 9 ÷ 1 / 32 ÷ 1 = 9/32.

Step-by-step explanation:

Using this expression Rn = (4/n) Σi=0n-1 [(1 + Δx)/Δx]^(-2i-2), we can now compute the Riemann sum for different values of n. As n gets larger, the Riemann sum gets closer to the exact value of the integral.

To use the definition of the definite integral to evaluate the given integral ∫31(2x^- 2)dx using a right-endpoint approximation to generate the Riemann sum, we first need to split the interval [3,1] into smaller subintervals. Let's choose n subintervals of equal width, where n is a positive integer. Then, the width of each subinterval will be Δx = (3-1)/n = 2/n.
Next, we need to choose the right endpoint of each subinterval as the sample point to evaluate the function. Therefore, the i-th sample point will be xi = 1 + iΔx, where i = 0, 1, 2, ..., n-1.Using these sample points, the Riemann sum for the given integral is given by:
Rn = Σi=0n-1 f(xi)Δx
where f(x) = 2x^-2 is the integrand.
Substituting the expressions for xi and Δx, we get:
Rn = Σi=0n-1 f(1 + iΔx)Δx
Rn = Σi=0n-1 (2/(1 + iΔx)^2)(2/n)
Now, we can simplify this expression using the formula for the sum of a geometric series:
Σi=0n-1 r^i = (1 - r^n)/(1 - r)
where r is the common ratio.
In our case, the common ratio is (1 + Δx)/Δx, so we have:
Rn = (4/n) Σi=0n-1 [(1 + Δx)/Δx]^(-2i-2)

Answer:

25 girls

Step-by-step explanation:

We Know

The ratio of boys to girls is 4:5. For every 4 boys, there are 5 girls.

To get from 4 to 20, we multiply by 5.

We Take

5 x 5 = 25 girls

So, there are 25 girls in class.

Answer: 25 girls are in the class

Step-by-step explanation: You can set up the ratio 4:5 as a fraction, \(\frac{4}{5}\) to find your answer. You are given the fact that 20 boys are in the class so now you can solve 2 ways.

Option 1 - Set up the equation algebraically as \(\frac{20}{x}\), where x = number of girls and set that equal to \(\frac{4}{5}\). This way allows you to see that the fraction must have the same ratio as 4:5. You can see that 4 x 5 = 20, so the multiple factor is 5. The variable x must equal 5 x 5, so x = 25.

Option 2 - Multiply the amount of boys given to you by the reciprocal of the ratio. Instead of using \(\frac{4}{5}\), you have to use \(\frac{5}{4}\) because there are more girls than boys in the class. This allows you to finish the problem by multiplying 20 x \(\frac{5}{4}\) to get the result of \(\frac{100}{4}\), which you may know simplifies into 25.
