I'm afraid I might not fully understand your question - which is to say I'm not certain what you are asking. Nonetheless, I will try to make my best speculation. If six friends enter college at the same time, one or more of them could graduate - though there is a 50% (0.5) probability that any...

Following the pattern I tried to describe in your previous question, start with your mean of 100 & mark 3 increments of 10 both below & above 100. The most common cases will fall right around 100 - from 90 to 110. The 2nd SD will include 80-89 & 111-120. The 3rd SD (called outliers)...

This distribution could have few samples or many samples, but the average - or mean - result is 10. The standard deviation of 3 tells us that a little more than 2/3 of all samples fall within +/-3 of that mean, so most results are from 7 to 13 (10-3 & 10+3). We call this the 1st standard...

Hi, Marilyn! I'm a nearby Wyzant tutor with much experience teaching algebra & general mathematics. That you're taking your class online could make scheduling tutoring sessions a bit easier & meeting location somewhat flexible. I work full time, but I'm often available after 5 or 6 pm...

We must assume that you pose the question, exactly as written, from a quiz, worksheet, homework, etc.: "What can be inferred after performing the experiments in the Atomic Theory lab?" The wording of this question implies that you already participated in an Atomic Theory lab...

When you say you want to learn to "do" quadratic equations, I take it to mean that you wish to learn to solve for the variable. Since you seem to be new at it, let's assume that you want help with some basic concepts that will help you move along toward the deeper concepts. The...

As tutors, our work puts us in an odd position. While part of our income depends upon spending time serving students, serving students means that we help them improve until they no longer need our assistance. In this sense, we work to make ourselves unnecessary. Some people might speculate that we would be motivated therefore to work less efficiently, to drag things out & spend more... read more

This is a problem of solving a triangle using the law of cosines: the square of measure of the unknown side is equal to the sum of the squares of the other two sides minus 2 times the product of those sides times the cosine of the angle opposite the unknown side. That the boats are traveling...

If this is a multiple-choice question, let's eliminate two possibilities immediately - I believe there has been no Supreme Court decision ever to cause slave settlements to be created. The Dred Scott decision settled the other two choices, at least for the time being, and was controversial for...

This question wants you to first find the proportion of each person's income compared to the total household income, and then to apply that proportion to the household bills, so that the person with the most income pays a larger amount - though the proportion or percentage is the same for both...

This problem can be solved with the given information, so we should find that no facts are missing: 12 + 5x = 6 - x Add x to each side: 12 + 5x + x = 6 - x + x Combine like terms: 12 + 6x = 6 Subtract 12 from each side: 12 - 12 + 6x = 6 - 12 Do...

Two hours is 120 minutes, so we can divide 120 by 25: 120/25 = 4.8 4.8 represents the number of 25-minute intervals in 2 hours. Since each 25-minute interval represents 70 people who can ride the Ferris wheel, we simply multiply 70 by 4.8: 70 x 4.8 = 336 So, theoretically, 336 people...

How about multiplying by 10?: (50x10)/(2.5x10) It now becomes 500/25: 500 divided by 100 is 5; 100 divided by 25 is 4; 5x4 is 20; Check your answer: 2.5x20=50

This may look confusing, but you should combine like terms (-4x-4x is really -8x) & do the arithmetic to make it become clear: -8x=64 Now you simply solve for x by dividing each side by -8.

It seems to me that Twain is actually satirizing adult or "learned" behavior, or perhaps conformity in general. Notice how he treats several topics, such as obedience, deference or respect, and lying. He inserts certain words that betray the stated purpose. For example, he writes, "obey...

Obviously, in these kind of examples, the solution must demonstrate that both sides are equal. The strategy is to discover which number n will make the fraction equivalent. Start with the numerators, those numbers at the top of the fractions, -2 & 10. Is there a factor of 10 that will leave...

Use of the word "simultaneously" indicates that we are to assume that neither jelly bean is chosen first, and therefore remaining choices do not decrease or increase in probability. I'm suspicious that this might not have been the intention, but I can only use the scenario as given...

Of course, as we are not told otherwise, we assume that there is an equal chance for any of the 9 children, whether girls or boys, in any combination or order, to be chosen. In this scenario, we are choosing 2 students out of 9 & want to know the probability of one being a girl &...

Since the slope & a point are given, we can use the point-slope form to create the equation. Point-slope form is (y-y1)=m(x-x1), where x1 & y1 are the given point & m is the slope. y-2=-2(x-8) y-2=-2x+16 y=-2x+14

We should assume that the slip of paper is returned to the bag after each game, so that each game begins with a full set of 26 letters. There being 26 letters, there is always 1/26 chance of drawing any particular letter in one draw. A. There being 5 vowels, there is a 5/26 chance of drawing...
