There is no solution that allows Sally to average an 85 with the given scores.

Let's start by finding the 5th score:

We know that the 4th score is 20 points less than the 5th score, so let's call the 5th score "x". Therefore, the 4th score is "x - 20".

We also know that the 5th score is 2/3 of the average of the first three scores. The average of the first three scores is (73 + 85 + 93)/3 = 83.67. So, (2/3) * 83.67 = 55.78 is the 5th score (rounded to two decimal places).

Therefore, x = 55.78/(2/3) = 83.67 is the 5th score.

Now, let's calculate the total score Sally needs to average an 85:

She already has 73 + 85 + 93 + 83.67 = 334.67 points. To average an 85 over seven tests, she needs a total of 7 * 85 = 595 points.

To find the scores she needs on the 6th and 7th tests, we can subtract the points she already has from the total points she needs:

595 - 334.67 = 260.33

So, Sally needs a total of 260.33 points on the 6th and 7th tests combined.

Let's call the 6th score "y" and the 7th score "z". We can set up an equation to solve for these two scores:

(y + z)/2 = 260.33

Multiplying both sides by 2:

y + z = 520.67

Since Sally needs to average an 85 over seven tests, the sum of all seven scores must be:

7 * 85 = 595

The sum of the first five scores is:

73 + 85 + 93 + 83.67 + 83.67 = 418.34

So, the sum of the last two scores must be:

595 - 418.34 = 176.66

Now we can set up another equation:

y + z = 176.66

We can solve this equation for one of the variables. Let's solve for "y":

y = 176.66 - z

Now we can substitute this into the first equation:

(176.66 - z + z)/2 = 260.33

176.66/2 = 260.33

88.33 = 260.33

This equation does not make sense.

Answer:

Step-by-step explanation:

The volume of a cylinder can be calculated using the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.

The current volume of the cylinder is:

V = π(12cm)^2(15cm)

V = π(144cm^2)(15cm)

V = 2160π cm^3

If the dimensions of the cylinder are tripled, then the new cylinder will have a radius of 3(12cm) = 36cm and a height of 3(15cm) = 45cm.

The new volume of the cylinder is:

V = π(36cm)^2(45cm)

V = π(1296cm^2)(45cm)

V = 58320π cm^3

Simplifying the expression, we get:

V ≈ 183,124.8 cm^3

Therefore, the volume of the new cylinder, when the dimensions are tripled, is approximately 183,124.8 cm^3.

The answer is C) 183,124.8 cm^3.

The difference between the two items are depends on sample size, the method of counting, or the criteria for classification can all impact the percentage calculation.

Percentage is a measure of the proportion of one value to another expressed as a fraction of 100. For example, if there are 100 apples, and 25 of them are red, then the percentage of red apples is 25%. Similarly, if there are 200 bananas, and 50 of them are ripe, then the percentage of ripe bananas is also 25%.

However, the context in which these percentages are calculated can be different. For instance, the way in which the 25% of red apples was calculated could be different from how the 25% of ripe bananas was calculated.

To illustrate this, let's consider an example. Suppose there are two cities, A and B, with populations of 10,000 and 5,000, respectively. In city A, 2,500 people have blue eyes, while in city B, 1,250 people have blue eyes. At first glance, it may seem that the percentage of people with blue eyes is the same in both cities, at 25%.

However, if we look closer, we can see that the actual number of people with blue eyes is different between the two cities. City A has twice as many people with blue eyes as city B, even though the percentage is the same.

Answer:

The mathematical property demonstrated by the statement 3 + (-6) = -6 + 3 is the commutative property of addition.

This states that: A + B = B + A

The commutative property of addition is the property that is demonstrated by the formula "3 + (-6) = -6 + 3".

This characteristic states that the sum is unaffected by the sequence in which two numbers are added. In other words, a + b = b + a for any two numbers a and b.

In this instance, the left side has 3 + (-6) which equals -3. We have -6 + 3 on the right side, which also equals -3. This indicates that the result is unaffected by the sequence in which the numbers are added.

We can thus write:

3 + (-6) = -6 + 3

-3 = -3

This demonstrates the truth of the assertion and serves as an illustration of the commutative property of addition.

the conditional probability that Jim's vacation was in Alaska given that we know he went surfing during the vacation is 0.1, or 10%.

Let A be the event that Jim's vacation was in Alaska, and let S be the event that Jim went surfing during the vacation. We want to find P(A|S), the conditional probability that Jim's vacation was in Alaska given that we know he went surfing during the vacation.

By Bayes' theorem, we have:

P(A|S) = P(S|A) * P(A) / P(S)

We can calculate each term as follows:

P(S|A) = 0.1: the probability that Jim went surfing during the vacation given that he was in Alaska.

P(A) = 0.5: the probability that Jim's vacation was in Alaska, since he tosses a fair coin to decide between Hawaii and Alaska.

P(S) = P(S|A) * P(A) + P(S|H) * P(H) = 0.1 * 0.5 + 0.9 * 0.5 = 0.5: the total probability of Jim going surfing during the vacation, since he either went surfing in Alaska with probability 0.1 or went surfing in Hawaii with probability 0.9.

Answer:

Part A:  1/2 or 0.5

Part B: heads is 8, tails is 7.

Part C: 8/15 or 0.533.

Part D: The theoretical and experimental probabilities are close but not exactly the same. This is because the theoretical probability is based on an ideal situation where the coin is fair, and the outcomes are equally likely. The experimental probability is based on actual data that may vary due to chance or other factors. The more trials we perform, the closer the experimental probability will get to the theoretical probability. It's like when you practice a skill and get better at it over time, but you still make mistakes sometimes.

Step-by-step explanation:

Part A: The theoretical probability of a fair coin landing on heads is 1/2 or 0.5. This is because there are two possible outcomes (heads or tails) and only one favorable outcome (heads). This is also the same probability of me winning the lottery, finding a unicorn, or getting a date.

Part B: I flipped a coin 15 times and got the following results:

H T H H T T H H T H T H T T H

or (in a more orderly fashion)

HHHHHHHH

TTTTTTT

The frequency of heads is 8 and the frequency of tails is 7. This means that I was slightly luckier than average, but not enough to make a difference. Maybe I should have used a different coin, or a different hand, or a different day.

Part C: The experimental probability of landing on heads is the ratio of the frequency of heads to the total number of trials. In this case, it is 8/15 or 0.533. This is slightly higher than the theoretical probability, but still within the margin of error. It's like when you order a pizza and get one extra slice, but it's the one with pineapple.

Part D: The theoretical and experimental probabilities are close but not exactly the same. This is because the theoretical probability is based on an ideal situation where the coin is fair, and the outcomes are equally likely. The experimental probability is based on actual data that may vary due to chance or other factors. The more trials we perform, the closer the experimental probability will get to the theoretical probability.

The probability of a carryout order being ready within 20 minutes is approximately 0.5507

We know that the time required for a carryout order to be ready for customer pickup follows an exponential distribution with a mean of 25 minutes. The probability density function for an exponential distribution is given by

f(x) = λe^(-λx)

where λ is the rate parameter

We can find the rate parameter λ using the mean

mean = 1/λ

λ = 1/mean = 1/25 = 0.04

So the probability of a carryout order being ready within 20 minutes is

P(X ≤ 20) = ∫₀²⁰ λe^(-λx) dx

P(X ≤ 20) = [-e^(-λx)]₀²⁰

P(X ≤ 20) = [-e^(-0.04x)]₀²⁰

P(X ≤ 20) = [-e^(-0.8)] - [-1]

The length of the string required to fly the kite at a height of 75 meters from the ground is 86.6 meters.

The sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, the opposite side is the height of the kite (75 m), and the hypotenuse is the length of the string that we need to find. We can set up an equation using the sine function:

sin(60 degrees) = opposite/hypotenuse

sin(60 degrees) = 75/hypotenuse

We can simplify the equation using the value of the sine of 60 degrees, which is √3/2.

√3/2 = 75/hypotenuse

To solve for the length of the string, we can cross-multiply and simplify:

hypotenuse = 75/(√3/2)

hypotenuse = (75*2)/√3

hypotenuse = 150/√3

hypotenuse = (150/√3) * (√3/√3) (to rationalize the denominator)

hypotenuse = (150√3)/3

hypotenuse = 50√3 meters = 86.6 meters.

83.3% is outside the range and therefore not a reasonable value.

We need to take into account the margin of error in order to determine which value is not a reasonable one for the actual proportion of the population that favors Candidate A. The range within which the actual population value is likely to fall is shown by the margin of error.

We can determine the likely range of the true population value as follows if the sample contained 80% of those who preferred Candidate A and the margin of error was 4%:

The lower bound of the range is 80% - 4% = 76%

The upper bound of the range is 80% + 4% = 84%

Therefore, any value outside of this range is not a reasonable value for the actual percentage of the population that prefers Candidate A.

75.6% is within the range and therefore a reasonable value.

82.4% is within the range and therefore a reasonable value.

76.4% is within the range and therefore a reasonable value.

83.3% is outside the range and therefore not a reasonable value.

If Jasmine saves $10 per week and her sister saves $7 per week, then Jasmine will have more "money-saved" than her sister in 10 weeks.

Let the number of weeks be denoted by "x",

We know that,

The Jasmine's initial-savings is = $50,

The amount which Jasmine weekly saves is = $10,

Her sister's initial savings is = $80,

The amount which her sister weekly-saves is = $7,

We have to find the value of "x" when Jasmine's savings exceed her sister's savings.

Total saving's of Jasmine after "x" weeks is calculated as,

⇒ Jasmine's total savings = Initial savings + (Weekly savings × Number of weeks),

⇒ $50 + ($10 × x),

Her sister's total savings after "x" weeks can be calculated as:

⇒ Sister's total savings = Initial savings + (Weekly savings × Number of weeks),

⇒ $80 + ($7 × x),

We write the equation to find the value of "x" when Jasmine's total savings exceed her sister's total savings,

⇒ 50 + 10x > 80 + 7x,

⇒ 50 + 10x - 80 > 7x,

⇒ 50 - 80 > 7x - 10x,

⇒ -30 > -3x,

⇒ -30/-3 < x,

⇒ 10 < x,

Step-by-step explanation:

The x-intercept is (-4, 0). The y-intercept can also be located by setting x = 0: f(0) = (0 + 4)/(0 - 3) = -4/3. So the y-intercept is (0, -4/3).

By rearranging the equation to take on its general form, f(x) = mx + c, where m is the slope, one can determine the slope of a linear function. By rearranging the equation to take on its general form, the vertex of a quadratic function can be determined.

The formula for f(x) is

f(x) = (x + 4)/(x - 3)

This function is rational, which means it is the ratio of two polynomials. X + 4 makes up the numerator, and X – 3 makes up the denominator.

Several things about this function are worth mentioning:

Due to the illogical nature of division by zero, the denominator cannot be equal to zero. As a result, at x = 3, there is a vertical asymptote and the function is undefined.

The function cannot be further simplified because the numerator and denominator have no shared factors.

The function approaches the horizontal asymptote y = 1 when x approaches positive or negative infinity because the maximum power of x in the numerator and denominator is the same (both are 1).

To graph this function, we can start by plotting the vertical asymptote at x = 3, and the horizontal asymptote at y = 1. The x-intercept can alternatively be determined by setting the numerator to zero:

x + 4 = 0

x = -4

So the x-intercept is (-4, 0).

f(0) = (0 + 4)/(0 - 3) = -4/3

So the y-intercept is (0, -4/3).

To determine the number of sheets of cardboard in a stack, we need to use the information given in the problem.

We know that each sheet of cardboard is 1 inch thick, and 16 sheets are stacked on top of each other in packages. The height of each stack is 21 inches.

Using the model of a ruler, we can divide the height of the stack (21 inches) by the thickness of each sheet (1 inch) to find the number of sheets in the stack.

21 ÷ 1 = 21

So, there are 21 sheets of cardboard in a stack.

To write an expression that can be used to determine the number of sheets of cardboard in a stack, we can use:

Number of sheets = height of stack ÷ thickness of each sheet

Or, substituting the given values: Number of sheets = 21 ÷ 1 = 21

This expression is simply a representation of the model we used earlier. It shows that we can determine the number of sheets in a stack by dividing the height of the stack by the thickness of each sheet. In this case, the expression yields the same result as the model, which is 21 sheets.
