C) 1/3

D) 3​

Answer:

idk

Step-by-step explanation:

The biconditional statement for the given conditional statement would be:

2x = 18 if and only if x = 9.

The given conditional statement "If 2x = 18, then x = 9" can be represented symbolically as p → q, where p represents the statement "2x = 18" and q represents the statement "x = 9".

To form the biconditional statement, we need to determine if the converse of the conditional statement is also true. The converse of the original statement is "If x = 9, then 2x = 18". Let's evaluate the converse statement.

If x = 9, then substituting this value into the equation 2x = 18 gives us 2(9) = 18, which is indeed true. Therefore, the converse of the original statement is true.

Based on this, we can write the biconditional statement:

2x = 18 if and only if x = 9.

The biconditional statement implies that if 2x is equal to 18, then x must be equal to 9, and conversely, if x is equal to 9, then 2x is equal to 18. The biconditional statement asserts the equivalence between the two statements, indicating that they always hold true together.

In summary, the biconditional statement is a concise way of expressing that 2x = 18 if and only if x = 9, capturing the mutual implication between the two statements.

The value of c does not affect the covariance of Y and Z.

The covariance of Y and Z can be calculated as Cov(Y, Z) = E[YZ] - E[Y]E[Z]. Since X is Bernoulli with parameter p and E[X] = p, we have E[Z] = pE[Y]. Hence,

Cov(Y, Z) = E[YZ] - E[Y]E[Z]

= E[YXY] - pE[Y]^2

= pE[Y^2 X] - pE[Y]^2

= p(E[Y^2]E[X] + Var[Y]p) - pE[Y]^2

= p(1 * p + 1 * p^2) - p^2

= p - p^2

It can be seen that the value of c does not affect the covariance of Y and Z.

Answer:

a. The null and alternative hypothesis can be written as:

\(H_0: \mu=3173\\\\H_a:\mu< 3173\)

b. A Type I error is made when a true null hypothesis is rejected. In this case, it would happen if it is concluded that the actual mean outstanding credit card debt of college undergraduate is significantly less than $3173, when in fact it does not.

A Type II error is made when a false null hypothesis is failed to be rejected. In this case, the actual mean outstanding credit card debt of college undergraduate is in fact less than $3173, but the test concludes there is no enough evidence to claim that.

Step-by-step explanation:

We have a prior study of the mean outstanding credit card debt of college undergraduate that states that it was $3173 in 2010.

A researcher believes that this amount has decreased since then.

Then, he has to perform a hypothesis test where the null hypothesis states that the mean is still $3173 and an alternative hypothesis that states that the actual credit card debt is significantly smaller than $3173.

The null and alternative hypothesis can be written as:

\(H_0: \mu=3173\\\\H_a:\mu< 3173\)

Hello,

(a) The exponential growth model is given by the equation P(t) = P0 * r^t, where P(t) is the population t years after 2010, P0 is the population in 2010 (7420), and r is the annual growth rate (2.3%).

Substituting the given values into the equation gives us:

P(t) = 7420 * 1.023^t

This is the equation that estimates the population t years after 2010.

(b) To estimate the population of the town in 2022, we can substitute t = 12 into the equation:

P(12) = 7420 * 1.023^12

Calculating this gives us:

P(12) = 7420 * 1.023^12 = 7420 * 1.291891 = 9593.45

So the estimated population of the town in 2022 is approximately 9593

5. The lengths are given as follows:

The three trigonometric ratios are given as follows:

In the second problem, we have that the side x is opposite to the angle of 52º, while the hypotenuse is of 13, hence the equation to solve for x is given as follows:

sin(52º) = x/13.

In item 3, the Pythagorean Theorem is used to solve for m, as follows:

n² + m² = l².

m² = l² - n²

m = square root (l² - n²).

In item 4, we have that the angle opposite to the leg of length 7 inches is of 62º, hence the hypotenuse is given as follows:

sin(62º) = 7/h

h = 7/sin(62º)

h = 7.9 inches.

The length BD in item 5 is obtained as follows:

cos(30º) = BD/5

BD = 5 x cos (30º)

BD = 4.3 cm.

Then the length BC is calculated as follows:

sin(22º) = 4.3/BC

The sequence \({fn(x)gn(x)}\)  uniformly converges, as desired.

To prove that the sequence \({fn(x)gn(x)}\) uniformly converges, we need to show that for every ε > 0, there exists an integer N such that for all n ≥ N and all x in the domain of the functions, |fn(x)gn(x) - [fn(x)gn(x)]_N| < ε.

Since {fn(x)} and {gn(x)} are uniformly convergent sequences, we know that for every ε > 0, there exist integers N1 and N2 such that for all n ≥ N1 and all x in the domain of the functions, |fn(x) - [fn(x)]_N1| < ε/2, and for all n ≥ N2 and all x in the domain of the functions, |gn(x) - [gn(x)]_N2| < ε/2.

Since {fn(x)} and {gn(x)} are also uniformly bounded, there exists a positive constant M such that |fn(x)| ≤ M and |gn(x)| ≤ M for all x in the domain of the functions.

Now, let ε > 0 be given. Choose N = max(N1, N2). Then for all n ≥ N and all x in the domain of the functions, we have:

\(|fn(x)gn(x) - [fn(x)gn(x)]_N|\\= |fn(x)gn(x) - fn(x)[gn(x)]_N + fn(x)[gn(x)]_N - [fn(x)gn(x)]_N| \\= |fn(x)(gn(x) - [gn(x)]_N) + ([fn(x)]_N - fn(x))[gn(x)]_N|\\= |fn(x)(gn(x) - [gn(x)]_N)| + |([fn(x)]_N - fn(x))[gn(x)]_N|\\= |fn(x)| |gn(x) - [gn(x)]_N| + |([fn(x)]_N - fn(x))| |[gn(x)]_N|\\\leq M |gn(x) - [gn(x)]_N| + M |[fn(x)]_N - fn(x)|\)

< M ε/2 + M ε/2

= ε

This shows that the sequence {fn(x)gn(x)} uniformly converges, as desired.
