Answer:

439.27, but if it’s round to the nearest tenth it’s 439.3

Step-by-step explanation:

When your measurement error is between 4.5% and 5%, the number of cases is 450.

The margin of error (MOE) is a measure of the uncertainty or statistical error in a survey's findings. When it comes to determining the survey's accuracy, the MOE is the most important consideration. When determining the sample size required to generate the lowest MOE possible, the survey creator's decision comes into play.

Let us assume that a 95 percent confidence level is used in a survey of a population. The MOE will be larger if a more rigorous confidence level is employed.

Margin of Error = (Critical Value) x (Standard Deviation) / square root of (Sample Size)

If the population size is less than 100,000, the MOE equation is usually used.

The most commonly used equation is n = (Z2 * P * Q) / E2 if the population size is greater than 100,000.

Hence, when the measurement error is between 4.5 and 5%, the number of cases is 450.

Answer:

y= \frac{15}{7}x + 7

not sure if that will work so

y = 15x/7x + 7

Step-by-step explanation:

The three solutions of the equation y = -2x - 1 are (–2, 3), (1, –3), and (2, –4).

To find the solutions, we substitute different values of x into the equation and solve for y.

For the first solution, when x is –2, we have y = -2(-2) - 1 = 3. Therefore, the first solution is (-2, 3).

For the second solution, when x is 1, we have y = -2(1) - 1 = -3. Thus, the second solution is (1, -3).

For the third solution, when x is 2, we have y = -2(2) - 1 = -4. Hence, the third solution is (2, -4).

These three points satisfy the equation y = -2x - 1, and therefore, they are the solutions of the equation. They represent coordinate pairs (x, y) where the equation holds true.

The arc length of the curve y = (1/3)x^(3/2) on the interval [0, 60] is 168 units.

To find the arc length of the curve y = (1/3)x^(3/2) on the interval [0, 60], we can use the formula for arc length:

L = ∫[a,b] √(1 + (dy/dx)^2) dx

In this case, we have y = (1/3)x^(3/2). Let's find dy/dx:

dy/dx = d/dx[(1/3)x^(3/2)]
= (1/3) * d/dx(x^(3/2))
= (1/3) * (3/2)x^(3/2-1)
= (1/2)x^(1/2)

Now, let's substitute this back into the formula for arc length:

L = ∫[0,60] √(1 + ((1/2)x^(1/2))^2) dx
= ∫[0,60] √(1 + (1/4)x) dx

To integrate this, let's make a substitution: u = 1 + (1/4)x.
Then, du = (1/4)dx, and dx = 4du.

Now the integral becomes:

L = ∫[0,60] √u * 4du
= 4∫[0,60] √u du
= 4 * (2/3) * u^(3/2) |[0,60]
= (8/3) * (u^(3/2) evaluated from 0 to 60)
= (8/3) * [(1 + (1/4)x)^(3/2)] evaluated from 0 to 60

Plugging in the limits:

L = (8/3) * [(1 + (1/4) * 60)^(3/2) - (1 + (1/4) * 0)^(3/2)]
= (8/3) * [(1 + 15)^(3/2) - (1)^(3/2)]
= (8/3) * [16^(3/2) - 1]

Calculating the final result:

L = (8/3) * [4^3 - 1]
= (8/3) * (64 - 1)
= (8/3) * 63
= 168

The number of ways to divide 10 players into two teams of 5 with Steve and Danny on different teams is -3668, implying that it's impossible to divide the teams as such. This result shows that the probability of both players being on the same team is one, and is related to the complement of the probability of them being on opposite teams.

We have our basketball team has 10 players, including Steve and Danny, and we need to divide them into two teams of 5 for an intrasquad scrimmage.

The number of ways of selecting r objects out of n is given by ⁿCr where,

ⁿCr = (n!) / [(n - r)! r!]

Here, the number of ways to choose 5 players out of 10 is ¹⁰C₅.

¹⁰C₅ = (10!) / [(10 - 5)! 5!]

¹⁰C₅ = (10 x 9 x 8 x 7 x 6) / (5 x 4 x 3 x 2 x 1)

¹⁰C₅ = 252

There are 252 ways to divide the 10 players into two teams of 5.

Using complementary probabilities, we can find the number of ways in which the teams can be picked such that Steve and Danny are on the same team.

For that, we need to calculate the number of ways in which Steve and Danny can be together, and then subtract this from the total number of ways.

Using the same logic, the number of ways to choose 4 more players out of 8 is ⁸C₄.

⁸C₄ = (8!) / [(8 - 4)! 4!]

⁸C₄ = (8 x 7 x 6 x 5) / (4 x 3 x 2 x 1)

⁸C₄ = 70

There are 70 ways to choose 4 players from the remaining 8 (excluding Steve and Danny).

We can consider Steve and Danny as one player, so we need to select 3 more players from the remaining 8 (excluding Steve and Danny).

The number of ways to do this is ⁸C₃.

⁸C₃ = (8!) / [(8 - 3)! 3!]

⁸C₃ = (8 x 7 x 6) / (3 x 2 x 1)

⁸C₃ = 56

There are 56 ways to select 3 players from the remaining 8 to join Steve and Danny.

Using the multiplication principle, we get the number of ways to select the entire team as 70 x 56 = 3920.

There are 3920 ways to choose the teams so that Steve and Danny are on the same team.

Now, using the complement rule, the number of ways to select the teams so that Steve and Danny are on opposite teams is given by the total number of ways minus the number of ways in which Steve and Danny are on the same team.

Using this, we can say that the number of ways to divide the 10 players into two teams of 5 such that Steve and Danny are on opposite teams is given by 252 - 3920 = -3668.

However, the answer is negative which means that there is no way to divide the teams such that Steve and Danny are on opposite teams.

Hence, the solution to the problem is related to the complement of the probability.

                 calories

Breakfast: 670  

Lunch:      555

Dinner:     910

Total = 2135 calories

Step-by-step explanation:

Let B, L and D, stand for the calories from Breakfast, Lunch, and Dinner

One day his calories from breakfast were 115 more, than his calories from​ lunch:  

B = L + 115

his calories from dinner were 200 less than twice his calories from lunch.:

D = 2L - 200

total caloric intake from meals was 2135:

B + L + D = 2135

------

We have B and D defined in terms of L from the first two equations, so use them in the third:

B + L + D = 2135

[L+115] + L + [2L-200] = 2135

4L - 85 = 2135

4L = 2220

L = 555 calories

B = L + 115

B = 555 + 115

B = 670 calories

D = 2L - 200

D = 2(555) - 200

D = 910 calories

================

Does B + L + D = 2135 calories?

  670 + 555 + 910 = 2135?

a) The chance that both servers fail is 0.05% (or 0.0005). b) The chance that exactly one of the servers fails is 5.9%. c) The chance that at least one of the servers fails is 5.95%. d) The assumption that the two servers fail independently may not be entirely realistic in all scenarios.

To find the probabilities in this scenario, we can use the probabilities of the main server and backup server failing, assuming they fail independently.

Let's denote:

P(M) = Probability of the main server failing = 0.01 (1%)

P(B) = Probability of the backup server failing = 0.05 (5%)

a) To find the chance that both servers fail, we need to calculate the probability of the intersection (AND) of the events:

P(both servers fail) = P(M) * P(B) = 0.01 * 0.05 = 0.0005 (0.05%)

b) To find the chance that exactly one of the servers fails, we can calculate the probability of the union (OR) of the mutually exclusive events:

P(exactly one server fails) = P(M) * (1 - P(B)) + (1 - P(M)) * P(B)

= 0.01 * (1 - 0.05) + (1 - 0.01) * 0.05

= 0.01 * 0.95 + 0.99 * 0.05

= 0.0095 + 0.0495

= 0.059 (5.9%)

c) To find the chance that at least one of the servers fails, we can calculate the probability of the complement (NOT) of both servers being operational:

P(at least one server fails) = 1 - P(both servers work)

= 1 - (1 - P(M)) * (1 - P(B))

= 1 - (1 - 0.01) * (1 - 0.05)

= 1 - 0.99 * 0.95

= 1 - 0.9405

= 0.0595 (5.95%)

d) The assumption that the two servers fail independently might not be entirely realistic in all scenarios. Factors such as shared infrastructure, common vulnerabilities, or external factors can introduce dependencies between the failure probabilities of the servers. If there are dependencies or shared factors that could cause correlated failures, the assumption of independence becomes less realistic.

a. The sampling method that I would use for the given scenario is stratified random sampling.

b. The sampling method that I would use for the given scenario is systematic sampling.

Stratified random sampling is the most effective way to get accurate results in this situation. The university wants to conduct a mail survey of its alumni to collect information about their current employment status to justify charging a higher tuition rate than other universities. Stratified random sampling divides the population into strata based on certain characteristics.

In this case, strata would be the alumni that have different degrees from the university. The information collected through this method will be more representative of the population than simple random sampling. It ensures that each stratum is represented accurately in the sample. It also minimizes the variability within each stratum. It is an effective way of ensuring that each stratum is properly represented.  

Systematic sampling involves selecting every kth element from a list of the population. In this situation, the Environmental Protection Agency (EPA) wants to inspect a sample of 1000 containers from the 40,000 containers known to be in landfills to determine if leakage from the containers has occurred. As the exact location of the containers is no longer known, systematic sampling can be used.

EPA can select every 40th container from the list of the population, as 40,000/1000 = 40. In this way, they will have a random sample of 1000 containers from the 40,000 containers. This sampling method is less time-consuming and more cost-effective than other sampling methods. It also ensures the sample is representative of the entire population.
