Probability that a student chosen randomly from the class plays neither a sport nor an instrument is 0.40

The possibility that an event will happen is referred to as the probability of the event. Mathematically, the likelihood of an event happening is represented by a number between 0 and 1.

Theoretically, P(A) represents the likelihood of event A.

In given problem (refer to image attached for table)

Total number of students = 8 + 7 + 3 + 12 = 30 students.

Out of this, Number of Students that neither plays sports as well as instruments are = 12

Let, 'A' be the event when student that neither plays sports as well as instruments gets choosen,

Then, Probability of occurance event A = P(A) = \(\frac{Favourable Outcomes}{ Total Outcomes}\)

Here, Favourable outcomes = 12 and Total outcomes = 30

Therefore, P(A) = 12/30 = 0.40

Hence, Probability that student choosen randomly from the class plays neither a sport nor an instrument is 0.40.

If the side length is n, then the perimeter is 9n. The closest multiple of 9 to 80 is 81, so n = 9.

Step-by-step explanation:

A nonagon is a shape with 9 sides. A regular shape means that all angles and sides of the shape is equal. That means let call the side of the nonagon, n. That means the perimeter which is 80, which means all side, n will add up.

\(n + n + n + n + n + n + n + n + n = 80\)

or

\(9n = 80\)

Solve for n

\(n = \frac{80}{9} \)

This rounded would make our interger side, 9

Based on the provided information to conduct the hypothesis test the condition met are random sampling, sample size, independence. From this sample, the taxpayer calculates a sample mean of $934 and a sample standard deviation of $619.

To conduct a hypothesis test, we need to ensure certain conditions are met. These conditions are:
1. Random sampling :The taxpayer used a random sample of 32 families, which helps to ensure the sample is representative of the population.
2. Sample size: The sample size is 32, which is considered a large enough sample size for a hypothesis test (generally, a sample size of 30 or more is considered large enough).
3. Independence: Since the sample is random and the sample size is less than 10% of the population (assuming there are more than 320 families), the independence assumption can be considered as met.
4. Approximately normal distribution: With a sample size of 32 (which is considered large), the Central Limit Theorem suggests that the sampling distribution of the sample mean will be approximately normal.
With these conditions met, the taxpayer can proceed with a hypothesis test to compare their sample mean with the IRS representative's claimed average and determine whether the real figure for medical care deductions is likely to be lower than $1,250.

The given scenario of monthly data on the number of flu cases seen in a hospital emergency department that shows consistent increases during certain months and decreases during others is an example of seasonality.

Seasonality refers to the predictable pattern of fluctuations in a time series data that occurs at regular intervals over a period of time. In this case, the seasonal pattern is related to the occurrence of the flu virus, which typically peaks during the winter months and decreases in the summer months.

Exponential smoothing is a statistical method used to forecast time series data, which involves assigning weights to past observations that decline exponentially over time. Holt's method is an extension of exponential smoothing that includes a trend component in addition to the level and seasonality components.

However, neither exponential smoothing nor Holt's method directly address seasonality in time series data. Therefore, the correct answer to the given question is "seasonality".

(3.14 x 121) + (3.14x15x11) = 898.04ft²

However, for cones like the ones in 6 and 8, we use a slightly different formula. √H² + r² = L first and then  π x r x (r + L).

For example  6.  H= 4in r=3in

⇒ √(4^2 + 3^2) =5

⇒  3.14 x 3 x (3 + 5) =75.36

To calculate the volume, we use the formula (V) = (1/3) x π x r² x H

The statement "A and B must be collectively exhaustive" means that the events A and B together cover all possible outcomes of the experiment. In other words, if A and B are collectively exhaustive, then there are no other possible outcomes of the experiment besides A and B.

In this case, we cannot determine whether A and B are collectively exhaustive just from their probabilities. It is possible that there are other events that could occur in the experiment that are not represented by A or B.

For example, if the experiment is flipping a coin, then A could represent the event of getting heads and B could represent the event of getting tails. In this case, A and B are collectively exhaustive because they cover all possible outcomes of the experiment. However, if there is a third event C that represents the coin landing on its edge, then A and B are not collectively exhaustive because there is another possible outcome of the experiment that is not represented by A or B.

Step-by-step explanation:

1. Since we know that Lila wants to use 1 cup of pretzels, we can multiply 1/2 x 1/2, which is 1.

2. Now that we multiplied 1/2 by 1/2, we have to multiply 1 1/4 by 1/2.

So 5/4 x 1/2 is 5/8.

3. Lila will need 5/8 cups of raisins.

The given figure is made up of a square, rectangle and an arc as shown in the figure. The perimeter will be 38 units and the area will be 95 square units.

Perimeter the the total length of the boundaries. Here we know all the lengths except the length of the arc.

Length of an arc = θ/360 × 2πr

 Here θ = 90

So length = 90/360 × 2× 3.14× 5 = 7.85 units

So perimeter = 10 + 5 + 7.85 + 5 + 10 = 37.85 ≈ 38 units

Area is formed by a rectangle, square and an arc

Area of the given rectangle = l×b = 10× 5 = 50 sq. units

Area of the square = s² = 5² = 25 sq. units

Area of the sector =  θ/360 × πr² = 90/360× 3.14× 5² = 19.64 sq. units

So the total area = 50 + 25 + 19.64 = 94.64 ≈ 95 sq. units

So perimeter is 38 units and area is 95 units².

Step 1: Simplify both sides of the equation.

0.5(5−7b)=8−(4b+6)

0.5(5−7b)=8+−1(4b+6)(Distribute the Negative Sign)

0.5(5−7b)=8+−1(4b)+(−1)(6)

0.5(5−7b)=8+−4b+−6

(0.5)(5)+(0.5)(−7b)=8+−4b+−6(Distribute)

2.5+−3.5b=8+−4b+−6

−3.5b+2.5=(−4b)+(8+−6)(Combine Like Terms)

−3.5b+2.5=−4b+2

−3.5b+2.5=−4b+2

Step 2: Add 4b to both sides.

−3.5b+2.5+4b=−4b+2+4b

0.5b+2.5=2

Step 3: Subtract 2.5 from both sides.

0.5b+2.5−2.5=2−2.5

To estimate the mean amount earned by a college student per month, we can use a point estimate and a 95% confidence interval. A point estimate is a single value that represents the best estimate of the population parameter, in this case, the mean amount earned by a college student per month. This point estimate can be obtained by taking the sample mean. To determine the 95% confidence interval, we need to calculate the margin of error and add and subtract it from the sample mean. This gives us a range of values that we can be 95% confident contains the true population mean. The conclusion is that the point estimate and 95% confidence interval can provide us with a good estimate of the mean amount earned by a college student per month.

To estimate the mean amount earned by a college student per month, we need to take a sample of college students and calculate the sample mean. The sample mean will be our point estimate of the population mean. For example, if we take a sample of 100 college students and find that they earn an average of $1000 per month, then our point estimate for the population mean is $1000.

However, we also need to determine the precision of this estimate. This is where the confidence interval comes in. A 95% confidence interval means that we can be 95% confident that the true population mean falls within the range of values obtained from our sample. To calculate the confidence interval, we need to determine the margin of error. This is typically calculated as the critical value (obtained from a t-distribution table) multiplied by the standard error of the mean. Once we have the margin of error, we can add and subtract it from the sample mean to obtain the confidence interval.

In conclusion, a point estimate and a 95% confidence interval can provide us with a good estimate of the mean amount earned by a college student per month. The point estimate is obtained by taking the sample mean, while the confidence interval gives us a range of values that we can be 95% confident contains the true population mean. This is an important tool for researchers and decision-makers who need to make informed decisions based on population parameters.
