The probability that at least 4 accounting majors are on the committee is P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

We can use the complement rule to solve this problem. The complement rule states that the probability of an event happening plus the probability of the event not happening is equal to 1.

In this case, we can find the probability that less than 4 accounting majors are on the committee and then subtract that from 1 to find the probability that at least 4 accounting majors are on the committee.

There are 6 accounting majors and 9 finance majors, for a total of 15 students.

To find the probability that fewer than 4 accounting majors are on the committee, we can use the binomial probability formula:

P(k) = (combination(8,k)) \(\times (6/15)^k \times (9/15)^{(8-k)\)

where k is the number of accounting majors on the committee.

To find the probability that fewer than 4 accounting majors are on the committee, we need to sum the probabilities for k = 0, 1, 2, and 3.

P(less than 4 accounting majors) = P(0) + P(1) + P(2) + P(3)

Finally, we can use the complement rule to find the probability that at least 4 accounting majors are on the committee:

P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

You can calculate the exact probability using the binomial coefficient and the binomial probability formula and then subtract that from 1 to get the final probability.

Answer:

x=0 and x=1/8

Step-by-step explanation:

This process may lead to a quadratic equation that needs to be solved, resulting in multiple x-values. These x-values will correspond to the points on the graph of y = f(x) where the tangent line passes through (1, -1).

To find the points on the graph of y = f(x) where the tangent line passes through the point (1, -1), we need to find the x-values that satisfy this condition.

First, we need to find the derivative of the function f(x). The derivative of f(x) = 3x^2 - 4x + 3 is f'(x) = 6x - 4.

Now, let's find the slope of the tangent line passing through the point (1, -1). We can use the point-slope form of a line, which is given by y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope of the line.

Substituting the values (1, -1) into the equation, we get y - (-1) = (6x - 4)(x - 1). Simplifying this equation, we have y + 1 = 6x^2 - 10x - 4.

To find the x-values that satisfy this equation, we can substitute f(x) into y. So, y + 1 = 6(f(x)) - 10x - 4. Substituting f(x) = 3x^2 - 4x + 3, we have y + 1 = 6(3x^2 - 4x + 3) - 10x - 4.

Now, we can simplify the equation and solve for x to find the x-values for which the tangent line passes through (1, -1).

This process may lead to a quadratic equation that needs to be solved, resulting in multiple x-values. These x-values will correspond to the points on the graph of y = f(x) where the tangent line passes through (1, -1).

It is likely that it will take Jacob more time to plant the perennials than the annuals.

Time is an abstract concept that is not tangible and cannot be seen, touched, or heard. It is a measure of the passage of events and is used to set and track schedules, create goals, and even measure the lifespan of an individual. Time is a precious commodity that cannot be replaced or taken back. Once it has passed, it is gone forever. Time is also a powerful force that can bring us joy and sorrow, success and failure. It is a constant reminder of how quickly our lives can change and how important it is to make the most of every moment.

Perennials require more attention when planting because they have a longer lifespan and are meant to come back year after year. Annuals, on the other hand, only last for one season. Therefore, they require less attention when planting. Jacob will need to make sure that he carefully places the perennials in the soil, as well as taking care to not damage the roots. He may also need to take extra time to trim any overgrowth from the plants. This extra care and attention will likely take more time than it would to plant the annuals.

The total amount of water deposited at the research site whenever an inch of rainfall occurs is 14400 cubic inches.

The first thing to do is to determine the volume of water deposited per square foot of surface area with 1 inch of rainfall.

This is given as 144 cubic inches (0.623 gallons).

To find the total amount of water that will be deposited at the research site whenever an inch of rainfall occurs, the surface area must first be determined.

All research sites are 100 square feet in area.

Now, multiply the volume of water deposited per square foot of surface area with 1 inch of rainfall by the surface area to obtain the total amount of water deposited at the research site with 1 inch of rainfall.

Volume of water deposited per square foot of surface area with 1 inch of rainfall

= 144 cubic inches (0.623 gallons)

Total surface area of all research sites

= 100 square feet

Total amount of water deposited at the research site with 1 inch of rainfall

= 144 cubic inches x 100 sq feet
= 14400 cubic inches

Therefore, the total amount of water deposited at the research site whenever an inch of rainfall occurs is 14400 cubic inches.

Answer:

Natalie bought 500 apples at $0.40 each, then she pays $0.40 500 times, this means that the total cost of the 500 apples is:

Cost = 500*$0.40 = $200

Now she threw away n apples from the 500 apples, then the number of apples that she has now is:

apples = 500 - n

And she sells the remaining apples for $0.70 each.

a) The amount that she gets by selling the apples is:

Revenue = (500 - n)*$0.70

b) We know that she did not make a loss, then the revenue must be larger than the cost, this means that:

cost ≤ revenue

$200 ≤ (500 - n)*$0.70

c) We need to solve the inequality for n.

$200 ≤ (500 - n)*$0.70

$200/$0.70 ≤ (500 - n)

285.7  ≤ 500 - n

n + 285.7 ≤ 500

n ≤ 500 - 285.7

n ≤ 214.3

Then the maximum value of n must be equal or smaller than 214.3

And n is a whole number, then we can conclude that the maximum number of rotten apples can be 214.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence.

A sequence in mathematics is an ordered collection of numbers that is typically defined by a formula or rule. Every number in the series is referred to as a term, and its location within the sequence is referred to as its index. Depending on whether the list of terms stops or continues indefinitely, sequences can either be finite or infinite. By their patterns or uniformity, sequences can be categorised, and the study of sequences is crucial to many areas of mathematics, such as calculus, number theory, and combinatorics. Mathematical, geometrical, and Fibonacci sequences are a few examples of popular sequence types.

given

The sequence's terms are all different by 7 (i.e., 12 - 5 = 19 - 12 = 26 - 19 =... = 7).

The following is a definition of a recursive formula for the nth element of the sequence:

a 1 = 5 (the first term of the series is 5) (the first term of the sequence is 5)

For n > 1, each term is derived by adding 7 to the preceding term, so a n = a n-1 + 7.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence. For instance, we have

a_2 = a_1 + 7 = 5 + 7 = 12

a_3 = a_2 + 7 = 12 + 7 = 19

a_4 = a_3 + 7 = 19 + 7 = 26

Answer:

x=20

Step-by-step explanation:

Substitute 15 for y

it will be 2/3 multiplied by 15 then you get 10

you add 10 to 30 getting 40

then you divide 40 by 1/2 getting 20

:)))

Answer:

x = 80

Step-by-step explanation:

First, plug the 15 into the y.

\(1/2x - 2/3(15) = 30\)

Use PEMDAS to solve the parentheses, 2/3 of 15 is 10.

\(1/2x - 10 = 30\)

Add 10 to both sides of the equation.

\(1/2x = 40\)

Divide each side by 1/2 (or multiply by it's reciprocal, which is 2)

That will get you your answer of x = 80

Answer:

45

Step-by-step explanation:

x/3 + 8 =23

=> x/3 = 23-8

=> x/3 = 15

=> x = 15 x 3

x = 45

Answer:

x=45

Step-by-step explanation:

To find x isolate the variables by using the properties of equality. First, subtract 8 from both sides, \(\frac{x}{3} = 15\). Then multiply both sides by 3, \(x=45\). Finally, to check you can plug 45 back into the equation, \(\frac{45}{3} +8=23\). Next, solve this equation and get 23=23, since this is a true statement 45 is correct.

You have to convert the following number into a fraction:

This is a periodic decimal number, which explicitely is 0.68888888....

In order to convert this number to a fraction you proceed as follow:

You put 0.68 and not 0.688 because to do the convertion you need only the first periodic number (that is, only the first 8). The key is to put in the numerator the complete number as whole number, that is, 68. To this number you subtract the whole part of the decimal number, this whole part is 0 because of the 0.688. Then, in the numerator you have 68 - 0. In the denominator you write a number composed only by 9's. The number of 9 numbers is determined by the number of digits of the first number in the numerator. That is two 9 numbers

Step-by-step explanation:

Given expression:

When multiplying decimals, multiply as if there are no decimal points:

\(\implies 6 \times 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 5 digits.

Put the same number of total digits after the decimal point in the product:

\(\implies (0.06) \cdot (0.154)=0.00924\)

-----------------------------------------------------------------------------------------------

Answer option A

\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)

When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.

Therefore:

\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)

Therefore, this is a valid answer option.

Answer option B

\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)

Multiply the numbers 6 and 154:

\(\implies 6 \times 154 = 924\)

Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).

\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)

Therefore, this is a valid answer option.

Answer option C

\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)

Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:

\(\implies 6 \cdot 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 3 digits.

Put the same number of digits after the decimal point in the product:

\(\implies 0.924\)

Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.

Answer option D

\(\boxed{6 \cdot 154 \cdot (0.00001)}\)

Again, employing the technique of multiplying decimals.

As there are a total of 5 digits after the decimals:

\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)

Therefore, this is a valid answer option.

Answer option E

\(\boxed{0.00924}\)

As we have already calculated, (0.06) · (0.154) = 0.00924.

Therefore, this is a valid answer option.

To calculate the amount of coal consumed during a 24-hour period, we need to use the given net power and thermal efficiency of the power plant.

a) The net power produced by the coal-fired steam power plant is 300 MW. The thermal efficiency of the power plant is given as 32 percent. To calculate the amount of coal consumed, we can use the formula:

Amount of coal consumed = (Net Power / Thermal Efficiency) / Calorific Value of Coal

First, convert the thermal efficiency from a percentage to a decimal by dividing it by 100:
Thermal Efficiency = 32/100 = 0.32

Next, substitute the values into the formula:
Amount of coal consumed = (300 MW / 0.32) / 28000 kJ/kg

Simplifying the equation, we have:
Amount of coal consumed = 937.5 kg/s

To calculate the amount of coal consumed during a 24-hour period, we need to multiply this by the number of seconds in 24 hours:
Amount of coal consumed in 24 hours = 937.5 kg/s * 24 hours * 3600 seconds/hour

b) To calculate the mass of air entering the boiler per unit time, we need to use the given mass air-fuel ratio.

The mass air-fuel ratio is given as 12 kg air/kg fuel. This means that for every kilogram of fuel consumed, 12 kilograms of air are required.

Since we have already calculated the amount of coal consumed in part (a), we can use this value to find the mass of air entering the boiler per unit time.

Mass of air entering the boiler per unit time = Mass of coal consumed per unit time * Mass air-fuel ratio

Substituting the values, we have:
Mass of air entering the boiler per unit time = 937.5 kg/s * 12 kg air/kg fuel

Simplifying the equation, we have:
Mass of air entering the boiler per unit time = 11250 kg/s

Therefore, the amount of coal consumed during a 24-hour period is 937.5 kg/s  and the mass of air entering the boiler per unit time is 11250 kg/s.
