wo way frequency tables
Two-way frequency tables show how many data points fit in each category.
Here's an example:
Preference Male Female
Prefers dogs 363636 222222
Prefers cats 888 262626
No preference 222 666
The columns of the table tell us whether the student is a male or a female. The rows of the table tell us whether the student prefers dogs, cats, or doesn't have a preference.
Each cell tells us the number (or frequency) of students. For example, the 363636 is in the male column and the prefers dogs row. This tells us that there are 363636 males who preferred dogs in this dataset.
Notice that there are two variables—gender and preference—this is where the two in two-way frequency table comes from.

Two way relative frequency tables
Two-way relative frequency tables show what percent of data points fit in each category. We can use row relative frequencies or column relative frequencies, it just depends on the context of the problem.
For example, here's how we would make column relative frequencies:
Step 1: Find the totals for each column.
Preference Male Female
Prefers dogs 363636 222222
Prefers cats 888 262626
No preference 222 666
Total 464646 545454
Step 2: Divide each cell count by its column total and convert to a percentage.
Preference Male Female
Prefers dogs \dfrac{36}{46}\approx78\%
46
36
≈78%start fraction, 36, divided by, 46, end fraction, approximately equals, 78, percent \dfrac{22}{54}\approx41\%
54
22

Prefers cats \dfrac{8}{46}\approx17\%

54

No preference \dfrac{2}{46}\approx4\%
46
2
≈4%start fraction, 2, divided by, 46, end fraction, approximately equals, 4, percent \dfrac{6}{54}\approx11\%
54
6

Total \dfrac{46}{46}=100\%
46
46

54

Notice that sometimes your percentages won't add up to 100\%100%100, percent even though we rounded properly. This is called round-off error, and we don't worry about it too much.
Two-way relative frequency tables are useful when there are different sample sizes in a dataset. In this example, more females were surveyed than males, so using percentages makes it easier to compare the preferences of males and females. From the relative frequencies, we can see that a large majority of males preferred dogs (78\%)(78%)left parenthesis, 78, percent, right parenthesis compared to a minority of females (41\%)(41%)left parenthesis, 41, percent, right parenthesis.

When reading a buret with graduated markings at every 0.1 ml, your recorded volume should read to a) hundredths place.
Definition and Function of the BuretteA burette is a long tube-shaped glass instrument with scale lines like a measuring pipette or measuring cup with the same cross section from top to bottom. At the bottom of this tool is equipped with a faucet as a place for the solution to come out at the mouth of the burette.
The function of the burette is as a tool to measure the solution based on the volume released. The burette size usually has a volume of 25 / 50 ml.
If the burette is being used, it must be supported firmly with a stand equipped with clamps to clamp the burette. Make sure that when clamping the burette in the stand and clamp the position of the burette must be perpendicular so that the scale reading is correct and does not cause paralax errors.

There were 50% more apples picked this year than last. If there were 230 pounds of apples picked this year, how many pounds were picked last year?
Answers
Explanation: Because you know that there were 50% more apples this year, you need to calculate 50% of 230. 50% is one half. So 230/2=115. Therefore, there were 115 pounds of apples picked last year.
Answer:
115 apples were picked last year
Step-by-step explanation
It says there are 50% more apples picked this year than last year. So, we divide 230 by 2 because 50% is half of 100%. 230÷2 = 115
115 apples
a ball is thrown vertically upward. after seconds, its height (in feet) is given by the function . after how long will it reach its maximum height? h(t)
Answers
The ball reaches its maximum height after 2 seconds.
To determine when the ball reaches its maximum height, we need to find when its velocity changes from positive to negative. The velocity of the ball is given by the derivative of its height, which is the function h'(t) = -16t. The ball's velocity is 0 when h'(t) = 0, so we need to solve -16t = 0.
The solution to this equation is t = 0. When t = 2, h'(t) = -32, which is negative, indicating that the ball is moving downward. So, the maximum height is reached when the velocity changes from positive to negative, which is at t = 2 seconds.

there are six members on a student council. two of these members will serve on a spring formal committee. how many possible spring formal committees are there?
Answers
There are 30 different combinations of two members who can be selected to serve on the spring formal committee.
Permutation is the arrangement of elements in a specific order. In this scenario, the elements are the six members of the student council, and the order in which they are arranged is important.
To find the number of permutations, we use the formula nPk, where n is the number of elements and k is the number of elements we want to arrange.
In this case, n = 6 and k = 2,
so we have
=> 6P2 = 6!/(6-2)!
=> 6!/(4!) = 6 x 5/1 = 30.
So, there are 30 possible spring formal committees that can be formed from the six members of the student council.

jennifer has three more dimes than nickels and three times as many quarters as nickels. if she has $7.50, how many quarters does she have? www.wyzant
Answers
Jennifer has 48 nickels, which means she has 144 quarters.
Let's call the number of nickels Jennifer has "n".
Since Jennifer has three more dimes than nickels, she has n + 3 dimes.
And since she has three times as many quarters as nickels, she has 3n quarters.
We can start by figuring out the total value of the nickels and dimes in terms of cents:
n * 5 cents + (n + 3) * 10 cents = 750 cents
Expanding the right side of the equation and solving for n:
5n + 10n + 30 cents = 750 cents
15n + 30 cents = 750 cents
15n = 720 cents
n = 48
So Jennifer has 48 nickels, which means she has 3 * 48 = 144 quarters.

The Fréchet distance is a mathematical metric for comparing the similarity of curves that takes into account the position and arrangement of curve points. Maurice Fréchet is honored by having his name used. The pairs of points that make up the Fréchet distance sweep continuously along their respective curves, so the Fréchet metric takes the flow of the two curves into account. As a result, the Hausdorff distance and other similarity measures for arbitrary point sets are inferior to the Fréchet distance for curves. Two curves might have a small Hausdorff distance but a large Fréchet distance.

A line has a slope of – 9 and includes the points ( – 9,1) and ( – 10,q). What is the value of q?
Answers
To find the value of q, we can use the point-slope form of a line:
y - y1 = m(x - x1)
where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) is a second point on the line.
In this case, we have the slope of the line as -9 and the point ( -9, 1), so we can plug in the values:
y - 1 = -9 (x - (-9))
Expanding and solving for y, we get:
y = -9x + 90
Next, we want to find the value of y when x = -10. Substituting this value into the equation:
q = -9(-10) + 90
Solving for q:
q = -90 + 90 = 0
So, the value of q is 0.

We have to write the given quadratic function in the form y = a(x - h)² + k.
2x² - 8x + 7 = (2x² - 8x) + 7

Answers
The probability of selecting 4 defective calculators is 0.0009.
The probability of selecting 4 defective calculators out of a group containing 47 defective and 29 non-defective calculators can be calculated using the formula for a combination. The formula is n!/r!(n-r)! where n is the total number of items and r is the number of items being selected. In this case, n is 76 (47 defective + 29 non-defective) and r is 4. Therefore, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.
To calculate this answer, the first step is to calculate the total number of combinations that can be made using 4 items out of 76 items. This is calculated using the formula n!/r!(n-r)!. The numerator, n!, is equal to 76! which is equal to 5.43e+102. The denominator, r!(n-r)!, is equal to 4!(76-4)! which is equal to 5.90e+09. By dividing the numerator by the denominator, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.
