Amir has a collection of 936 trading cards. He wants to put them
in boxes with 25 trading cards in each box. How many boxes will
Amir fill? How many trading cards will be left over?

The sample size that would be required for the width of 99% is 2653.

The number of subjects involved in a sample size is referred to as the sample size in market research. A set of people chosen from the general community who are thought to be a representative sample size for that particular study is referred to as the sample size.

The following details are given:

Margin of error, E = 0.025; Significance Level, = 0.01

The proportion p is estimated to be p = 0.53.

The significance level with a critical value of 0.01 is 2.58.

The smallest sample size needed to estimate the population proportion p within the necessary margin of error is determined using the formula shown below:

n >= p*(1-p)*(zc/E)2 n = 0.53 *(1 - 0.53*)2 n = 2652.97 *(1-p)*(2.58/0.025)2

As a result, we determine that n = 2653 is the minimal sample size needed to satisfy the criteria that

n >= 2652.97 and that it must be an integer value.

Sample size is 2653.

A student's probability of having a sister are 1/2 or 0.5 if they do not have a brother.

Using the above data table, we must determine the likelihood that a student without a brother also has a sister. Analysing the table now

has a sibling: 5

possesses no sisters: 2

has an 18-year-old brother

possesses no brothers: 4

We are looking for the likelihood that a student has a sister and neither a brother (as indicated by the statement "Does not have a brother"). In this instance, there are two children who do not have a brother but do have a sister, making that number the number of positive outcomes.

No matter whether a student has a sister or not, the total number of outcomes is equal to the number of students who do not have a brother. According to the table, there are 4 students without brothers.

As a result, the likelihood that a student who doesn't have a brother will have a sister can be determined as follows:

Probability is calculated as the ratio of the number of favourable outcomes to all possible outcomes.

Probability equals 2/4

Probability equals 0.5 or half.

The correct 95% confidence interval for the proportion of drivers who react more quickly to the new light is (0.53, 0.67).

To calculate the confidence interval for the proportion of drivers who react more quickly to the new light, we can use the formula:

CI = p ± zα/2 √((p(1-p))/n)

where p is the proportion of drivers who react more quickly to the new light, n is the sample size, and zα/2 is the z-score for the desired confidence level (in this case, 95% corresponds to zα/2 = 1.96).

Substituting the given values, we get:

CI = 0.6 ± 1.96 √((0.6*0.4)/n)

Since we don't know the sample size, we can't calculate the exact confidence interval. However, we can see that the margin of error is proportional to 1/√n, which means that larger sample sizes will result in narrower confidence intervals.

Based on the given answer choices, we can see that the margin of error is 0.07, which corresponds to a sample size of around 200. So, if we assume that the sample size is large enough to use the normal approximation, we can calculate the confidence interval as:

CI = 0.6 ± 0.07

which gives us (0.53, 0.67) as the correct answer.

The average speed of the car is 51 kph. The result is obtained by dividing the total distance by the total time taken.

Average speed is the overall speed of a moving object during a given amount of time. It can be expressed as

Avg speed = Total distance covered / Total time taken

The speed itself can be found by the following formula.

s = d/t

Where

A car can travel at the following speeds.

Find the average speed!

We should convert the unit of time from minutes to hour.

t₃ = 45 minutes = ¾ h

t₄ = 15 minutes = ¼ h

We count the time and distance in each travels.

t₁ = d₁/s₁ = 20/40 = ½ h

t₂ = d₂/s₂ = 25/50 = ½ h

d₃ = s₃×t₃ = 60 × ¾ = 45 km

d₄ = s₄×t₄ = 48 × ¼ = 12 km

Avg speed = (s₁ + s₂ + s₃ + s₄)/(t₁ + t₂ + t₃ + t₄)

Avg speed = (40 + 50 + 60 + 48)/(½ + ½ + ¾ + ¼)

Avg speed = 102/2

Avg speed = 51 kph

Hence, the car has the average speed of 51 kph.

Based on both the mean and median values, we can conclude that Wide Awake typically sells more coffee per hour than Coffee Ground.

What are the mean and median?

The mean and median are two measures of central tendency that can be used to describe a set of data. The median is the middle value in the data set when the values are arranged in order from lowest to highest. If there are an even number of values, the median is the average of the two middle values.

To determine which coffee shop typically sells the most amount of coffee per hour, we need to compare the measures of center (mean and median) of the data for each shop.

Calculating the mean of each dataset, we get:

Mean of Coffee Ground = (1.5+20+3.5+12+2+5+11+7+2.5+9.5+3+5) / 12 = 6.5/2 = 5.42 gallons

Mean of Wide Awake = (2.5+10+4+18+4+3+6+5+2.5) / 9 = 56 / 9 = 6.22 gallons

Calculating the median of each dataset, we get:

Median of Coffee Ground = 4.25 gallons

Median of Wide Awake = 4.5 gallons

Comparing the measures of the center, we see that the mean value of coffee sold per hour at Coffee Ground is approximately 5.42 gallons, while the mean value of coffee sold per hour at Wide Awake is approximately 6.22 gallons.

Therefore, on average, Wide Awake sells more coffee per hour than Coffee Ground.

However, we also see that the median value of coffee sold per hour at Wide Awake is 4.5 gallons, while the median value of coffee sold per hour at Coffee Ground is 4.25 gallons.

This suggests that the middle value of coffee sold per hour is higher for Wide Awake than for Coffee Ground.

Therefore, based on both the mean and median values, we can conclude that Wide Awake typically sells more coffee per hour than Coffee Ground.

The p-value for the right-tailed t-test with a test statistic of 0.73 and a sample size of 39 is approximately 0.2352 (rounded to 4 decimal places).

To find the p-value for a right-tailed t-test, we need to use the t-distribution table or a calculator.

Given that the test statistic t = 0.73 and the sample size is 39, we can calculate the p-value using the t-distribution.

For a right-tailed t-test with a sample size of n = 39, the degrees of freedom are given by df = n - 1 = 39 - 1 = 38.

Since this is a right-tailed test, the p-value represents the probability of observing a t-value greater than or equal to the given test statistic.

Using a t-distribution table or a calculator, we find that the p-value for t = 0.73 with 39 degrees of freedom is approximately 0.2352.

Therefore, the p-value for the right-tailed t-test with a test statistic of 0.73 and a sample size of 39 is approximately 0.2352 (rounded to 4 decimal places).

The probability that Kennedy randomly selects an oatmeal cookie and then a sugar cookie is 9/30 * 6/29, which simplifies to 3/29.


1. First, we need to find the total number of cookies in the bag. There are 7 chocolate chip, 8 peanut butter, 6 sugar, and 9 oatmeal cookies, which add up to 30 cookies (7+8+6+9=30).
2. Next, we find the probability of selecting an oatmeal cookie first. There are 9 oatmeal cookies out of a total of 30 cookies, so the probability is 9/30. After Kennedy eats the oatmeal cookie, there are now 29 cookies left in the bag.
3. Now, we need to find the probability of selecting a sugar cookie after eating the oatmeal cookie. There are 6 sugar cookies out of 29 remaining cookies, so the probability is 6/29.
4. To find the overall probability, we multiply the probability of the first event (selecting an oatmeal cookie) by the probability of the second event (selecting a sugar cookie), which is (9/30)*(6/29).

The probability that Kennedy randomly selects an oatmeal cookie from the bag, eats it, and then randomly selects a sugar cookie is 9/30 * 6/29, which simplifies to 3/29 as the final reduced fraction.

The results from Part B support the hypothesis from Part A, indicating that the students scored better on the Unit 1 test and that the Unit 1 test has more variation than the Unit 2 test.

Part 1: Looking at the data plots, it appears that the students scored better on the Unit 1 test than on the Unit 2 test. The Unit 1 test has more variation than the Unit 2 test, as there are more scores clustered towards either end of the scale, with fewer scores in the middle.

Part 2: The mean of the Unit 1 test is 77 and the mean absolute deviation is 11. This was calculated by adding up all of the scores and dividing by the total number of scores, which was 11. The mean absolute deviation was calculated by subtracting the mean from each score, taking the absolute value, and then taking the average of all of the absolute values.

Part 3: The results from Part B do support the hypothesis from Part A, as the mean score for the Unit 1 test is higher than the mean score for the Unit 2 test, as well as the mean absolute deviation for the Unit 1 test is higher than the mean absolute deviation for the Unit 2 test. This indicates that the Unit 1 test has more variation than the Unit 2 test, suggesting that the students scored better on the Unit 1 test.

Answer:

A≈ 65ft 2

Step-by-step explanation:

Answer:

a₁ = 42

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

Given a₅₀ = 140 and a₅₁ = 142 , then

a₁ + 49d = 140 → (1)

a₁ + 50d = 142 → (2)

Subtract (1) from (2) term by term to eliminate a₁

0 + d = 2

d = 2

Substitute d = 2 into (1)

a₁ + 49(2) = 140

a₁ + 98 = 140 ( subtract 98 from both sides )

a₁ = 42
