(Round up your answers to the next whole number.) Required: a. To update this study, how many public accountants should be contacted?"
Putting all the given values in the formula, we get:n = [1.96² x 0.21 x 0.79] / 0.03²On solving, we get,n = 2734.84 ≈ 2735Therefore, 2735 public accountants should be contacted to update the study with a margin of error of 3% and a 95% level of confidence. Answer: 2735.
Given Information :A study conducted several years ago reported that 21% of public accountants changed companies within 3 years.
The American Institute of CPAs would like to update the study.
They would like to estimate the population proportion of public accountants who changed companies within 3 years with a margin of error of 3% and a 95% level of confidence.
Required:a. To update this study, how many public accountants should be contacted? Solution: Given that: the percentage of public accountants changed companies within 3 years is 21%.The level of confidence is 95%.
The margin of error is 3%.We have to find out the sample size.To find the sample size we use the formula :n = [Z² x p x q ] / E²
Where, Z = Standard normal deviation corresponding to a 95% confidence level is 1.96.p = proportion = 21/100 = 0.21q = 1-p = 1-0.21 = 0.79E = margin of error = 3/100 = 0.03
Putting all the given values in the formula, we get:n = [1.96² x 0.21 x 0.79] / 0.03²On solving, we get,n = 2734.84 ≈ 2735Therefore, 2735 public accountants should be contacted to update the study with a margin of error of 3% and a 95% level of confidence. Answer: 2735.

Jillian surveyed students at her school and found out the following probabilities:
\begin{aligned} &P(\text{freshman})=0.30 \\\\ &P(\text{plays instrument})=0.20 \\\\ &P(\text{freshman and instrument})=0.10 \end{aligned}
P(freshman)=0.30
P(plays instrument)=0.20
P(freshman and instrument)=0.10
Find the probability that a student plays an instrument given they are a freshman.
Step-by-step explanation:
Use conditional probability.
P(A given B) = P(A and B) / P(B)
P(instrument given freshman) = P(instrument and freshman) / P(freshman)
P(instrument given freshman) = 0.10 / 0.30

Wendy has taken two tests with scores of 77 and 80. To get an 82
average, what must her grade be on the third test?
Please help
Answer:
89
Step-by-step explanation:
Given that Wendy took 2 tests and scored, 77 and 80 respectively, let x represent the grade of Wendy's third test.
To get an average grade of 82, let's generate an equation to find x (Wendy's grade on her third test).
Average grade = sum of all 3 grades all over 3
\( 82 = \frac{77 + 80 + x}{3} \)
\( 82 = \frac{157 + x}{3} \)
Multiply 3 by both sides
\( 82*3 = \frac{157 + x}{3}*3 \)
\( 246 = 157 + x \)
Subtract 157 from each side of the equation
\( 246 - 157 = 157 + x - 157 \)
\( 89 = x \)
Wendy must score 89 on her third test to have an average of 82.

Answer:
\(2x+y=150\)
Step-by-step explanation:
Number of games = 4
Number of controllers = 2
Mr. Gutierrez and his brother want to purchase a game console that is $300.
Let \(x\) denotes number of games and \(y\) denotes number of controllers.

Meg has 7 over 8 jug of orange juice. How many 1 over 2 jug servings can Meg get from that jug?
Meg can get 1 and 3/4 servings of 1/2 jug from her 7/8 jug of orange juice.
Meg has a 7/8 jug of orange juice, and she wants to know how many 1/2 jug servings she can get from it. To solve this problem, we need to divide the total amount of orange juice by the amount of orange juice in each serving.
First, we need to convert the 7/8 jug to an equivalent fraction with a denominator of 2. To do this, we can multiply both the numerator and denominator of 7/8 by 2, which gives us 14/16.
Next, we can divide 14/16 by 1/2 to find out how many 1/2 jug servings Meg can get from the jug. To divide fractions, we invert the second fraction and multiply. So we have:
14/16 ÷ 1/2 = 14/16 x 2/1 = 28/16
Now, we need to simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 4. So we have:
28/16 = (28 ÷ 4) / (16 ÷ 4) = 7/4
Therefore, Meg can get 7/4 or 1 and 3/4 servings of 1/2 jug from her 7/8 jug of orange juice.

a pulley on a dock is 5 feet above the water level. a rope on the pulley is attached to a boat in the water. the rope is being pulled in at a rate of 3 ft/sec. find the rate of change of the angle of elevation, which is the angle formed by the rope attached to the boat and the horizon, when the boat is 12 feet from the dock. please give an exact simplified answer.
The rate of change of the angle of elevation is -2π/3 radians/second.
We can use the tangent ratio to solve this problem. Since the rope is attached to the boat, we can draw a right triangle with the rope as the hypotenuse. The angle of elevation is the angle formed by the rope and the horizon.
The pulley is 5 feet above the water level, so the length of the opposite side (the side adjacent to the angle) is 5 feet. The length of the hypotenuse is 12 feet, since the boat is 12 feet from the dock.
Using the tangent ratio, we can calculate the angle of elevation:
tan(θ) = opp/hyp = 5/12
θ = arctan(5/12) = 0.927 rad
Now, since the rope is being pulled in at 3 ft/sec, the length of the hypotenuse is decreasing at a rate of 3 ft/sec. Therefore, the rate of change of the angle of elevation is:
rate of change of θ = -(3 ft/sec) / (12 ft) = -2π/3 radians/second

If the sampled population distribution is skewed, then in most cases the sampling distribution of the mean can be approximated by the normal distribution if the sample size n is at least 30. T/F
True. The central limit theorem states that if the sample size n is large enough (usually considered to be at least 30), then the sampling distribution of the mean will be approximately normal, regardless of the shape of the population distribution.
The sampling distribution of the mean can be approximated by the normal distribution if the sample size (n) is at least 30. This statement is based on the Central Limit Theorem, which states that the sampling distribution of the mean of a random sample drawn from any population will approach a normal distribution as the sample size increases, regardless of the shape of the population distribution. A sample size of 30 is often considered the threshold for approximating a normal distribution in such cases.

which factors will influence the margin of error when the population standard deviation is unknown? check all that apply.
We need to know about margin of error to solve the problem. The factors that influence margin of error are confidence level and sample size.
Margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result will reflect the result of a census of the entire population. Margin of error is influenced by three factors, confidence level, sample size and population standard deviation. In absence of population standard deviation, the margin of error is influenced by confidence level and sample size.
Therefore the margin of error is influenced by confidence level and sample size.

Write the equation that describes the simple harmonic motion of a particle moving uniformly around a circle of radius 7 units, with angular speed 2 radians per second.
The equation that describes the simple harmonic motion of the particle is:
x = 7 * sin(2t + φ)
The equation that describes the simple harmonic motion of a particle moving uniformly around a circle can be represented as:
x = A * sin(ωt + φ)
In this equation:
x represents the displacement of the particle at time t.
A represents the amplitude of the motion.
ω represents the angular frequency or angular speed of the motion.
t represents time.
φ represents the phase constant.
In the given scenario, the particle is moving uniformly around a circle of radius 7 units, with an angular speed of 2 radians per second. In circular motion, the displacement can be represented by the arc length along the circumference of the circle.
Since the angular speed is 2 radians per second, the angular frequency (ω) is also 2 radians per second.
Since the particle is moving uniformly, the amplitude of the motion (A) is equal to the radius of the circle, which is 7 units.
The phase constant (φ) determines the initial position of the particle at t = 0.
