Based on historical data in Oxnard college, we believe that 37% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required
Answer:
A sample size of 1031 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).
The margin of error is of:
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
37% of freshmen do not visit their counselors regularly.
This means that \(\pi = 0.37\)
98% confidence level
So \(\alpha = 0.02\), z is the value of Z that has a pvalue of \(1 - \frac{0.02}{2} = 0.99\), so \(Z = 2.327\).
You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?
A sample size of n is required.
n is found when M = 0.035. So
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
\(0.035 = 2.327\sqrt{\frac{0.37*0.63}{n}}\)
\(0.035\sqrt{n} = 2.327\sqrt{0.37*0.63}\)
\(\sqrt{n} = \frac{2.327\sqrt{0.37*0.63}}{0.035}\)
\((\sqrt{n})^2 = (\frac{2.327\sqrt{0.37*0.63}}{0.035})^2\)
\(n = 1030.4\)
Rounding up:
A sample size of 1031 is required.
Solve the exponential equation for x. 3^3x-2 = 9^4x-1 x=
The solution of the exponential equation 3^(3x-2) = 9^(4x-1) is x = 0.
We can solve this exponential equation for x by using logarithms. We can take the logarithm of both sides of the equation, using any base that we prefer. For instance, we can use the natural logarithm, ln:
ln(3^(3x - 2)) = ln(9^(4x - 1))
Now, we can use the properties of logarithms to simplify both sides of the equation. First, recall that ln(a^b) = b ln(a), for any positive value of a and any real value of b. Therefore, we have:
(3x - 2) ln(3) = (4x - 1) ln(9)
Next, we can use another property of logarithms, namely ln(a^b) = b ln(a) = ln(c) → a^b = c, to eliminate the natural logarithms from both sides of the equation. Specifically, we can rewrite ln(9) as ln(3^2), and then use the power rule for logarithms, ln(a^b) = b ln(a), to get:
(3x - 2) ln(3) = (4x - 1) ln(3^2) = 2 (4x - 1) ln(3)
Now, we can simplify the equation by multiplying out the coefficients of ln(3) on the left-hand side:
3x ln(3) - 2 ln(3) = 8x ln(3) - 2 ln(3)
Then, we can collect like terms:
3x ln(3) - 8x ln(3) = -2 ln(3) + 2 ln(3)
Finally, we can solve for x by factoring out ln(3) and dividing both sides by the resulting factor:
(3 ln(3) - 8 ln(3)) x = 0
-5 ln(3) x = 0
x = 0
Therefore, the solution of the exponential equation 3^(3x-2) = 9^(4x-1) is x = 0.

Question 3 A 44-metres long fire-fighting ladder is leaned against a building, as shown in the diagram. The base of the ladder is 7 metres from the building and 3 metres above the ground. How high on the building will the ladder reach?
The ladder will reach a Height of approximately 43.46 meters on the building.
To find out how high on the building the ladder will reach, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the ladder forms a right triangle with the ground and the building. The base of the ladder is 7 meters, the height of the building is what we need to find, and the length of the ladder is given as 44 meters.
Using the Pythagorean theorem, we can set up the equation:
(Height of the building)^2 + 7^2 = 44^2
Simplifying the equation, we have:
(Height of the building)^2 + 49 = 1936
Subtracting 49 from both sides, we get:
(Height of the building)^2 = 1887
To find the height of the building, we take the square root of both sides:
Height of the building = √1887
Calculating the square root of 1887, we find that the height of the building is approximately 43.46 meters.
Therefore, the ladder will reach a height of approximately 43.46 meters on the building.

what is the length of an arc which substends an angle of 60digree at the center of a circle of radius 1/2m?
0.5236 meters is the length of the given arc.
The formula for the length of an arc is given by:
Arc Length = (θ/360) * 2πr
Where:
θ is the central angle in degrees.r is the radius of the circle.In this case, the central angle is 60 degrees and the radius is 1/2 meters.
Plugging the values into the formula, we have:
Arc Length = (60/360) * 2π(1/2)
Arc Length = (1/6) * π
Arc Length = π/6

In this scenario, we have two registers x5 and x6, holding hexadecimal values. We will use these values to answer the given questions about register manipulation.
a) To determine the contents of register x31 after the instruction "addi x31, x5, 32", we need to add 32 to the value in x5 and store the result in x31. The value in x5 is 01a74cd0hex, which is equivalent to 277968848 in decimal. Adding 32 to this value, we get 277968880 decimal. Therefore, the contents of register x31 after the instruction is executed would be 277968880 decimal.

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

Find the 66th
term in the following
arithmetic sequence
-92, -85, -78, -71, ...
Answer:
The \(66\)th term is \(363\).
Step-by-step explanation:
To find the \(n\)th term, the formula is \(7n - 99\). Since we want to find the \(66\)th term, we can plug \(n\) for \(66\). So our expression is now \(7 \cdot 66 - 99 =\) \(66\)th term. Solving this we have
\(462 - 99 = 66\text{th term}\\363 = 66\text{th term}\\\). Therefore, the \(66\)th term is \(\boxed{363}\).
Answer:
a₆₆ = 363
Step-by-step explanation:
the nth term of an arithmetic sequence is
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 92 and d = a₂ - a₁ = - 85 - (- 92) = - 85 + 92 = 7 , then
a₆₆ = - 92 + (65 × 7)
= - 92 + 455
= 363
