Answer:To completely fill in the basketball court, Glenwood High School will need 60 cubic yards of concrete.

Since one bag of concrete fills 0.5 cubic yards, we can calculate the number of bags needed by dividing the total cubic yards by the cubic yards per bag:

Number of bags = 60 cubic yards / 0.5 cubic yards per bag

Number of bags = 120 bags

Therefore, Glenwood High School needs to order at least 120 bags of concrete to completely fill in the basketball court. Since the school ordered more than enough concrete to completely fill in the court, they likely ordered more than 120 bags of concrete.

Answer:

w=-4.5

Step-by-step explanation:

12÷3/8=4.5

-w= 4.5

w= -4.5

To solve the equation -3/8 w = 12 for w, you need to isolate w. You do this by dividing both sides by -3/8 which is equivalent to multiplying by -8/3 (the reciprocal). This gives w = -32.

To solve the given equation -3/8 w = 12 for w, we need to isolate w on one side of the equation. To do this, you can divide both sides of the equation by -3/8. In mathematics, dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of -3/8 is -8/3. So, when you multiply both sides of the equation by -8/3 you get:

w = 12 * (-8/3)

Simplify this further to get: w = -32

There is a theoretical probability of approximately 26.2% that at least one of the 27 students in the group has the H1N1 influenza virus.

To calculate the theoretical probability that at least one of the 27 students has the H1N1 influenza virus, we can use the complement rule. The complement of the event "none of the 27 students have the H1N1 influenza virus" is the event "at least one of the 27 students has the H1N1 influenza virus."

The probability that a student does not have the H1N1 influenza virus is 1 - 0.01 = 0.99. Since the students are selected independently, the probability that none of the 27 students have the virus is (0.99)^27.

Using the complement rule, the probability that at least one of the 27 students has the H1N1 influenza virus is:

1 - (0.99)^27 ≈ 0.262

Expressed as a percentage with 3 decimal places, the theoretical probability is approximately 26.2%.

The conditions for normality have been met for the sampling distribution of the difference in sample means of two populations of coins (pennies and quarters) where a random sample of 25 pennies was selected, and the mean age of the sample was 32 years, and a random sample of 35 quarters was taken, and the mean age of the sample was 19 years.

For each of the samples, the sample size is sufficiently large (n1 = 25, and n2 = 35), and we have no information about the population distribution. We can use the Central Limit Theorem to conclude that the sampling distribution of the difference in sample means is approximately normal.

Population standard deviation is known or the sample size is sufficiently large: We do not know the population standard deviation of the two populations. Therefore, we must ensure that the sample size of each group is large enough to justify using the Central Limit Theorem.

Both the sample sizes (25 and 35) are greater than 30. Therefore, the sample size is sufficiently large, and we can use the Central Limit Theorem to assume that the sampling distribution of the difference in sample means is approximately normal.

The sample size of 300 people is large enough to apply the Central Limit Theorem.

The Central Limit Theorem (CLT) states that for a random sample of independent and identically distributed (i.i.d.) variables with a finite population mean and standard deviation, as the sample size increases, the distribution of the sample means approaches a normal distribution, regardless of the shape of the population distribution.

In this case, we are interested in the percentage of people in the sample who are infected with COVID-19. The sample size of 300 people is sufficiently large for the CLT to be applicable. Since the sample is randomly selected and the individuals in the sample are assumed to be independent, we can expect the distribution of the sample proportion (percentage) of infected individuals to be approximately normal.

To compute the probability that the percentage of infected individuals is between 4% and 6%, we can use the normal distribution approximation.

We need to calculate the z-scores corresponding to the lower and upper bounds (4% and 6%) and then find the area under the normal curve between those z-scores.

Answer:

The price of the car is $12,000. The individual makes a down payment of 25%, so the loan amount is $9,000. The interest rate is 8% compounded monthly, so the monthly interest rate is 0.08/12 = 0.00667. The loan term is 48 months, so the number of payments is 48.

The monthly payment is calculated using the following formula:

Monthly payment = Loan amount * (Monthly interest rate) / (1 - (1 + Monthly interest rate) ^ (-Number of payments))

Monthly payment = $9,000 * (0.00667) / (1 - (1 + 0.00667) ^ (-48))

Monthly payment = $219.72

The total interest charges are calculated using the following formula:

Total interest charges = Total payments - Loan amount

Total interest charges = 48 * $219.72 - $9,000

Total interest charges = $1,510.72

Therefore, the correct answer is: c. R= $219.72; interest charges= $1,510.72.

The probability that the first two marbles will be red and the third one will be blue is 35/2448

The probability of picking a red marble on the first draw is 5/18, and given that the first marble was red, the probability of picking another red marble on the second draw is 4/17 (since there are now only 4 red marbles left out of 17 total marbles).

Finally, given that the first two marbles were red, the probability of picking a blue marble on the third draw is 7/16 (since there are now 7 blue marbles left out of 16 total marbles).

To find the overall probability of this sequence of events, we multiply the probabilities of each individual event.

Therefore, the probability of picking two red marbles and one blue marble in this specific order is:

(5/18) × (4/17)× (7/16)

= 0.0285

To answer your question, Hailey is using the distributive property to simplify the calculation of 7(18). The distributive property allows us to break up a multiplication problem into smaller, more manageable parts.

Hailey has rewritten 18 as 10 + 8, and she will now use the distributive property to calculate 7 times each of these two numbers separately.
So, the two products that Hailey will add together to get the final product are 7 times 10 (which is 70) and 7 times 8 (which is 56).
To check her work, she can add these two products together:
70 + 56 = 126

The product of z1 and z2 is 81/2 + 27i*sqrt(6)/2 by using trigonometric identities.

To find the product of z1 and z2, we can use the formula for multiplying complex numbers:
z1 * z2 = (18*cos225 + 18i*sin225) * (3*cos240 + 3i*sin240)
Using trigonometric identities, we can simplify this expression:
z1 * z2 = 54*cos225*cos240 + 54i*sin225*cos240 + 54i*cos225*sin240 + 54*sin225*sin240
Now we can use the values of cosine and sine for 225 and 240 degrees:
cos225 = -sqrt(2)/2, sin225 = -sqrt(2)/2
cos240 = -sqrt(3)/2, sin240 = -1/2
Substituting these values, we get:
z1 * z2 = 54*(-sqrt(2)/2)*(-sqrt(3)/2) + 54i*(-sqrt(2)/2)*(-1/2) + 54i*(-sqrt(3)/2)*(-sqrt(2)/2) + 54*(-sqrt(2)/2)*(-1/2)

The probability of obtaining 3 candies or fewer that are red in a random sample of 13 candies depends on the probability of selecting a red candy and follows a binomial distribution.

To calculate the probability, we can use the binomial probability formula and sum up the probabilities for each possible outcome (0, 1, 2, and 3 red candies) using the appropriate values for the number of trials, the probability of success (selecting a red candy), and the desired number of successes (3 or fewer). The result will provide the probability that the sample contains 3 or fewer red candies.

The probability of obtaining 3 candies or fewer that are red in a random sample of 13 candies can be calculated using the binomial probability formula. In this case, we are interested in the probability of success (selecting a red candy) and the desired number of successes (3 or fewer red candies) out of a fixed number of trials (13 candies).

The binomial probability formula is given by P(X = k) = C(n, k) * p^k * (1 - p)^(n - k), where P(X = k) is the probability of getting exactly k successes, n is the number of trials, p is the probability of success, and C(n, k) is the binomial coefficient.

To calculate the probability, we need to consider the cases of obtaining 0, 1, 2, and 3 red candies. We can then sum up the probabilities for each case.

For example, if the probability of selecting a red candy is p = 0.4, we can calculate the probabilities for 0, 1, 2, and 3 red candies using the formula and sum them up to find the overall probability.
