Sand falls from an overhead bin and accumulates in a conical pile with a radius that is always three times its height. Suppose the height of the pile increases at a rate of 3 cm/s when the pile is 14 cm high. At what rate is the sand leaving the bin at that instant? Let V and h be the volume and height of the cone, respectively. Write an equation that relates V and h and does not include the radius of the cone. (Type an exact answer, using π as needed.)

The expected value of E(X+6) is 34 and the variance of Var(5X) is 450.

Given that the expected value of X is E(X) = 28 and variance of X is Var(X) = 18.

We have to find the expected value of E(X+6) and variance of Var(5X).

Expected value of E(X+6)E(X+6) = E(X) + E(6)

By linearity of expected values, we have

E(X+6) = E(X) + E(6)

= 28 + 6 = 34.

Therefore, the expected value of E(X+6) is 34.

Variance of Var(5X)Var(5X) = Var(X)*5²

By linearity of variance, we have

Var(5X) = Var(X)*5²

= 18*25

= 450.

Therefore, the variance of Var(5X) is 450.

Thus, the expected value of E(X+6) is 34 and the variance of Var(5X) is 450. Hence, the correct option is 34,450.

The expected value of E(X+6) is 34 and the variance of Var(5X) is 450.

SOLUTION:

Step 1:

In this question, we are given the following:

A pancake recipe asks for one and one-half times as much milk as flour.

If three and one-half cups of milk are used, what quantity of flour would then be needed, according to the recipe?

Step 2:

The details of the solution are as follows:

The pancakes require 1.5 cups of milk and 1 cup of flour or a ratio of 1.5:1 or a fraction of

(1.5) / (1)

If you have 3.5 cups of milk you need x cups of flour

Set up a ratio of 1.5 / 1 = 3.5 / x

(1.5 divided by 1 equals 3.5 divided by x)

Cross multiply one numerator by the other denominator, and then the other way.

1.5x = 3.5

divide both sides by 1.5

x = 35/15 = 2 1/3 cups

CONCLUSION:

The quantity of flour that would be needed, according to the recipe =

(a) For p(x) = c(ſ)^x, x = 1, 2, 3, ..., the value of the constant c, such that p(x) satisfies the condition of being a probability mass function (pmf) of one random variable X is : (ſ - 1)/ſ.

(b) For p(x) = cm, x = 1, 2, 3, 4, 5, 6, and zero elsewhere, the value of the constant c, such that p(x) satisfies the condition of being a probability mass function (pmf) of one random variable X is :  1/21.

(a) For p(x) = c(ſ)^x, x = 1, 2, 3, ..., and zero elsewhere, we need to ensure that the sum of all probabilities equals 1. Since the function is defined for positive integers, we can use the geometric series formula:

Σ(c(ſ)^x) = 1, where x ranges from 1 to infinity.

c * (ſ/(ſ - 1)) = 1 (geometric series formula)

To find c, we simply rearrange the equation:

c = (ſ - 1)/ſ

So for this pmf, the constant c is (ſ - 1)/ſ.

(b) For p(x) = cm, x = 1, 2, 3, 4, 5, 6, and zero elsewhere, we again need the sum of all probabilities to equal 1:

Σ(cm) = 1, where x ranges from 1 to 6.

c * (1 + 2 + 3 + 4 + 5 + 6) = 1

c * 21 = 1

To find c, we rearrange the equation:

c = 1/21

So for this pmf, the constant c is 1/21.

Step-by-step explanation:

negative four raised to the sixth power divided by negative four raised to the fourth power

because  negative four raised to the fourth power divided by negative four raised to the second power = negative four raised to the second power

negative four raised to the sixth power divided by negative four raised to the fourth power also = negative four raised to the second power

The answer is A: negative four raised to the second power divided by negative four raised to the fourth power. This is obtained by applying the rules of exponents, specifically, when dividing with the same base, subtract the exponents.

This question pertains to exponents division rules. According to the rule of Power of a Power in exponents, when you divide expressions with the same base, you subtract the exponents. So if you have negative four raised to the fourth power (-4⁴) and you want to divide it by negative four raised to the second power (-4²), you subtract 2 from 4 to get an exponent of 2. This results in a negative four raised to the second power (-4²). So, the correct option from the given choices in your question is A: negative four raised to the second power divided by negative four raised to the fourth power.

The tourist had $1200.91 in US dollars when he left the country.

The American tourist exchanged 80% of $8175 to local currency, which is:

0.8 x $8175 = $6540

To calculate how much local currency the tourist received for $6540, we can use the buying rate of Kshs.83.25 per US dollar:

Amount in local currency = $6540 x Kshs.83.25 per US dollar = Kshs.544335

After spending Kshs.443,595, the tourist had Kshs.544,335 - Kshs.443,595 = Kshs.100,740 left.

To calculate how much US dollars the tourist can buy with Kshs.100,740, we can use the selling rate of Kshs.84.05 per US dollar:

Amount in US dollars = Kshs.100,740 / Kshs.84.05 per US dollar = $1200.91

Therefore, the tourist had $1200.91 in US dollars when he left the country.

Yes, the implications of leaving farm fields unused for the economy's PPF diagram can be seen in the output of agricultural products.

The PPF diagram shows the maximum output of two products that an economy can produce at a given time, and it is shaped like a curve. When farm fields are left unused, the amount of agricultural products that can be produced is decreased, resulting in a shift in the PPF curve inwards. This means that the economy has to sacrifice other goods to maintain the same level of production of agricultural products, leading to an opportunity cost. Thus, leaving farm fields unused has implications for the economy's PPF diagram, as it reduces the output of agricultural products, resulting in a shift in the PPF curve inwards.

Hypothesis: If two angles are congruent.

Conclusion: Then they have the same measure.

The hypothesis states that if two angles are congruent, which means they are identical in shape and size, then the conclusion is that they have the same measure. In other words, when two angles are congruent, their measures are equal.

Angles are typically measured in degrees or radians. When we say that two angles are congruent, it implies that the measures of those angles are the same. This can be understood through the transitive property of congruence, which states that if two angles are congruent to a third angle, then they are congruent to each other.

For example, if angle A is congruent to angle B, and angle B is congruent to angle C, then it follows that angle A is congruent to angle C. This implies that the measures of angle A and angle C are equal, as congruent angles have the same measure.

In conclusion, the hypothesis that if two angles are congruent implies that they have the same measure is valid and supported by the principles of congruence and the transitive property.
