 1 and  2 are supplementary angles. The m  2 = 142°, what is the m  1?

Answer: This tells us that the voltage at point C is 5 volts higher than the voltage at point A. However, we still don't know the absolute voltage at either point A or point C.

Step-by-step explanation:

To determine the absolute voltage at point C, we need to know the voltage values at either point A or point B. With only the information given about the current and the grounding of one corner, we cannot determine the absolute voltage at point C.

However, we can determine the voltage difference between two points in the circuit using Kirchhoff's voltage law (KVL), which states that the sum of the voltage drops around any closed loop in a circuit must be equal to zero.

Assuming the circuit is a simple loop, we can apply KVL to find the voltage drop across the resistor between points A and C. Let's call this voltage drop V_AC:

V_AC - 5 = 0 (since the current is counterclockwise and the resistor has a resistance of 1 ohm)

V_AC = 5

The angular area of the HST's field of view is 25 square degrees.

The field of view is the extent of the sky that the Hubble Space Telescope (HST) can observe at a given time. It is usually measured in degrees.

To calculate the angular area, we can use the formula for the area of a circle:

Area = π * (angular size/2)^2

Where π is a mathematical constant approximately equal to 3.14, and the angular size is in degrees.

Let's say the angular size of the HST's field of view is 10 degrees.

First, we divide the angular size by 2:

10 degrees / 2 = 5 degrees

Next, we square the result:

5 degrees * 5 degrees = 25 square degrees

Algebraic word problems are questions that require translating sentences to equations. The equations we need to write will only involve basic arithmetic operations and a single variable. Usually, the variable represents an unknown quantity in a real-life scenario.

SOLUTION STEPS

Step 1: Name the variable.

The variable, in this case, is n.

Step 2: Identify the mathematical operation in this mathematical statement.

Product refers to multiplication. Therefore, we will be using the multiplication operation for the question.

Step 3: Write out the algebraic expression for the statement: "The product of 7 and a number".

Since we are representing the number with n, the product of n and 7 will be given to be:

ANSWER:

The correct option is OPTION B.

(a)  The joint PMF of S₁, S₂, ..., Sn is: P(S₁ = s₁, S₂ = s₂, ..., Sₙ = sₙ) =\((1 - p)^{(s_1 + s_2 + ... + s_n) } \times p^n\)

(b)  The random variables S₁,..., Sn are  independent.

(c)  the cumulative distribution function (CDF) of U is:

\(F(u) = (1 - \sum (1 - p)^{(k)} \timesp)^n\)

To compute the joint probability mass function (PMF) of S₁, S₂, ..., Sn, we need to consider the number of failures before each success.

(a) Joint probability mass function (PMF) of S₁, S₂, ..., Sn:

Let's first define the random variable S as the sequence of failures until the first success:

S = (S₁, S₂, ..., Sn)

Now, let's calculate the PMF of S:

P(S = (s₁, s₂, ..., sₙ))

Since the random variables X₁, X₂, ..., Xₙ are independent Bernoulli random variables with success probability p.

The probability of getting s failures before the first success is given by:

\(P(S_1 = s_1) = (1 - p)^{s_1} \times p\)

The probability of getting s₂ additional failures before the second success is:

\(P(S_2 = s_2) = (1 - p)^{s_2} \times p\)

\(P(S_3 = s_3) = (1 - p)^{s_3} \times p\)

And so on, until the probability of getting sₙ additional failures before the nth success:

\(P(S= s) = (1 - p)^{s} \times p\)

Now, since the random variables S₁, S₂, ..., Sn are independent, the joint PMF is the product of the individual probabilities:

P(S = (s₁, s₂, ..., sₙ)) = P(S₁ = s₁) × P(S₂ = s₂)×... × P(Sₙ = sₙ)

Therefore, the joint PMF of S₁, S₂, ..., Sn is:

P(S₁ = s₁, S₂ = s₂, ..., Sₙ = sₙ) =\((1 - p)^{(s_1 + s_2 + ... + s_n) } \times p^n\)

(b)

To determine whether the random variables S₁, S₂, ..., Sn are independent, we need to check if the joint PMF factorizes into the product of the individual PMFs.

Let's consider three random variables, S₁, S₂, and S₃:

P(S₁ = s₁, S₂ = s₂, S₃ = s₃) = P(S₁ = s₁) ×P(S₂ = s₂) × P(S₃ = s₃)

Using the joint PMF calculated in part (a), we can rewrite this as:

\((1 - p)^{(s_1 + s_2 + s_3)} p^3 = (1 - p)^{(s_1)} \times p \times (1 - p)^{(s_2)} \times p \times (1 - p)^{(s_3)}\times p\)

Simplifying, we have:

\((1 - p)^{(s_1 + s_2 + s_3)} p^3 = (1 - p)^{(s_1 + s_2 + s_3)} p^3\)

Since the equation holds true for any values of s₁, s₂, and s₃, we can conclude that the random variables S₁, S₂, and S₃ are indeed independent.

(c)

To compute the CDF of U, we need to determine the probability that U is less than or equal to a given value u.

CDF of U:

F(u) = P(U ≤ u) = 1 - P(U > u)

Since U represents the maximum value among S₁, S₂, ..., Sn, we have:

P(U > u) = P(S₁ > u, S₂ > u, ..., Sn > u)

Using the independence of S₁, S₂, ..., Sn, we can express this probability as:

P(U > u) = P(S₁ > u)×P(S₂ > u) × ...× P(Sn > u)

The probability that a single random variable Si is greater than u (where Si represents the number of failures between the (i-1)th and the ith success) is:

P(Si > u) = 1 - P(Si ≤ u) = 1 - ∑(k=0 to u) P(Si = k)

Using the PMF derived in part (a), we can calculate this probability:

\(P(Si > u) = 1 - \sum (1 - p)^(^k^) \times p\) (k=0 to u)

Finally, substituting this back into the expression for P(U > u), we have:

\(P(U > u) = (1 - \sum (1 - p)^{(k)} \timesp)^n\) (k=0 to u)

Therefore, the cumulative distribution function (CDF) of U is:

\(F(u) = (1 - \sum (1 - p)^{(k)} \timesp)^n\)

The fencing needed to keep our rabbits is approximately 44 meters

Given that a circle garden has an area of 25π and the radius is increased by 2 meters and fencing is sold only in one meter section. We need to find how much fencing is needed to keep our rabbits.

Step 1: Area of a circle is given by:

A = πr²

where

r is the radius of the circle garden.

So, the area of circle garden with radius r is given by:

25π = πr²

Dividing both sides by π,

we get:

r² = 25r = ± 5

The radius cannot be negative.

So, r = 5 m

Step 2: When the radius is increased by 2 m, the new radius is:

r + 2 = 5 + 2

= 7 m

Step 3: The length of fencing required will be equal to the circumference of the new circle with radius 7 m.

Circumference of the new circle with radius 7 m is given by:

C = 2πr

= 2π(7)

≈ 43.98 m

Therefore, the fencing needed to keep our rabbits is approximately 44 meters.

The value of Za/2 to construct a confidence interval with a level of 95% is approximately 1.96.

To construct a confidence interval with a level of 95%, we need to find the critical value Za/2. This value corresponds to the z-score that represents the area under the standard normal distribution curve outside the confidence interval.

The confidence level of 95% indicates that we want to capture the middle 95% of the distribution and leave 5% (2.5% on each tail) in the tails. Therefore, we need to find the z-score that leaves 2.5% in each tail.

To determine the value of Za/2, we can use a standard normal distribution table or statistical software. The value represents the z-score at the critical point, where the area to the right of the z-score is a/2.

For a level of 95%, a is equal to 1 - confidence level = 1 - 0.95 = 0.05. Dividing a by 2, we get a/2 = 0.05 / 2 = 0.025.

Using a standard normal distribution table or statistical software, we find that the z-score corresponding to an area of 0.025 in the right tail is approximately 1.96. Therefore, the critical value Za/2 for a 95% confidence interval is approximately 1.96.

In summary, the value of Za/2 to construct a confidence interval with a level of 95% is approximately 1.96.

a) The 90% confidence interval for the average salary of an entry-level computer engineer is of: (16.28, 83.72).

b) The sample contains the value 80, hence it does not give sufficient evidence that the average salary of all entry-level computer engineers is different from $80,000.

c) The 90% confidence interval for the standard deviation of entry level salaries is of: (6.67, 389.86).

The bounds of the confidence interval are given according to the following rule:

\(\overline{x} \pm t\frac{s}{\sqrt{n}}\)

In which the variables of the equation are presented as follows:

The sample in this problem is given as follows:

30, 50, 70.

Hence the values of the parameters are given as follows:

\(\overline{x} = 50, s = 20, n = 3\)

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 3 - 1 = 2 df, is t = 2.92.

Then the lower bound of the interval is of:

\(\overline{x} - t\frac{s}{\sqrt{n}} = 50 - 2.92\frac{20}{\sqrt{3}} = 16.28\)

The upper bound of the interval is of:

\(\overline{x} + t\frac{s}{\sqrt{n}} = 50 + 2.92\frac{20}{\sqrt{3}} = 83.72\)

The bounds of the confidence interval for the standard deviation are given as follows:

\(\frac{(n - 1)s^2}{\chi^2_\frac{\alpha}{2}} \leq \sigma \leq \frac{(n - 1)s^2}{\chi^2_{1 - \frac{\alpha}{2}}}\)

The critical values of the chi-square distribution with a confidence level of 90% and 2 df are given as follows:

\(\chi^2 = 0.1026, \chi^2 = 5.9915\)

Hence the lower bound of the interval is of:

2 x 20/5.9915 = 6.67.

Based on the information provided, we can conduct a hypothesis test to determine if a majority of all students at Ohio University believe the academics are 'very strong'.

Let's set up the null and alternative hypotheses:

Null hypothesis (H₀): The proportion of all students who believe the academics are 'very strong' is equal to 50% or less.

Alternative hypothesis (H₁): The proportion of all students who believe the academics are 'very strong' is greater than 50%.

To test these hypotheses, we can use a one-sample proportion test. We will compare the sample proportion (55%) to the hypothesized proportion (50%) and assess if the difference is statistically significant.

Using appropriate statistical methods, such as calculating the test statistic and obtaining the p-value, we can evaluate the evidence against the null hypothesis. If the p-value is less than the chosen significance level (e.g., 0.05), we would reject the null hypothesis and conclude that a majority of all students at Ohio University believe the academics are 'very strong'. Otherwise, if the p-value is greater than the significance level, we would fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim of a majority belief.

Please note that without the actual test results or the p-value, we cannot make a definitive conclusion in this particular case.
