- a greater percentage of subjects taking the placebo did not report fatigue.

Step-by-step explanation:

60% of the subjects took the drug and 40% took the placebo.  

56% of the subjects did not report fatigue and 44% reported fatigue.

28%  of subjects taking the placebo did not report fatigue and 12% report fatigue.

Answer:

Step-by-step explanation:

A cross-table is about several variables, where we can get different analysis about each aspect of each variable.

In this case, we have Drug and Placebo, each of them has certain percentage about Reported Fatigue and Did not Report Fatigue.

According to the table, 60% of the people took drug, and 40% took placebo. That means more subjects took the drug than took the placebo.

Additionally, 56% of the people didn't report fatigue, and 44% reported fatigue. Therefore, a greater percent of the subjects did not report fatigue.

Answer:

B

Step-by-step explanation:

First you would look at the x coordinate which is 4. So on the x-axis you would find four. Next you would look at the y coordinate which is -2. Then you go on the y-axis and find -2. Finally, you would go to 4 on x-axis and go DOWN (since it is negative) 2 spots.

B point is located at (4, –2)

Coordinate geometry (or analytic geometry) is defined as the study of geometry using coordinate points. the usage of coordinate geometry, it is possible to find the distance between two points, divide lines in the m:n ratio, find the mid-point of a line, calculate the area of a triangle within the Cartesian plane, and so on.

Answer:

Z = -6

Step-by-step explanation:

The scatter plot that shows a strong, negative linear association between variables is Scatter Plot A.

Option A is the correct answer.

A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.

In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.

The position of each point on the graph represents the values of both variables for that particular observation.

We have,

A strong, negative linear association between variables means that as one variable increases, the other variable decreases consistently and predictably.

This relationship is described as negative because the two variables move in opposite directions.

For example, if you were studying the relationship between temperature and the demand for ice cream, you would expect a strong, negative linear association because as the temperature increases, the demand for ice cream decreases.

In terms of a scatterplot, this relationship would be seen as a cluster of points that form a straight line sloping downwards from left to right.

Thus,

The scatter plot that shows a strong, negative linear association between variables is Scatter Plot A.

Answer:

1/1

Step-by-step explanation:

SO the chances are 1/1, or 100%. There are 2^3 = 8 possible outcomes after tossing a fair coin fairly 3 times. The 8 possible outcomes are: TTT, HTT, THT, TTH, HHT, HTH, THH, HHH.

The probability of getting heads only on the last toss of three tosses of a fair coin is 0.25 or 25%. This theoretical probability, according to the law of large numbers, tends to become closer to the observed frequency as the number of repetitions increases.

The subject of this question can be classified under Mathematics. It falls under the area of probability, specifically the concept of binomial probability. When a fair coin is tossed, there are two possible outcomes: heads (H) or tails (T). The probability of getting either outcome is 0.5. This is the theoretical probability based on the assumption that the coin is fair and unbiased.

Tossing the coin three times introduces eight possible combinations (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). Out of these, only two combinations (TTH, THT) yield heads (H) on the last toss alone.

Therefore, the probability of getting heads only on the last toss is the number of successful outcomes divided by the total number of outcomes, i.e., 2 out of 8 or 0.25 (25%). This probability is a theoretical probability that deals with long-term expectation and it tends to become closer to the observed or empirical frequency as the number of repetitions increases (law of large numbers).

Answer:

2x -y = 13

Step-by-step explanation:

y+3= 2(x-5)

Distribute

y+3 = 2x-10

Subtract 2x from each side

-2x +y+3 = 2x-2x-10

-2x +y +3 = -10

Subtract 3 from each side

-2x+y+3-3 = -10-3

-2x+y = -13

Multiply each side by -1 since A should be positive

Answer:

8(59 1/4 x 1) -58 = 100

Step-by-step explanation:

This would simplify to x = -2 1/10  or x = 50/237

As 100/474 = -2 1/10 or -50/237

We balance the 8. then we balance the 50ml so that 100/424 = -25/106 = -2  4/10 so we see that 50ml minimum in the problem is required and this creates a 1/8 increase with each pump.

Proof is the difference of -2 1/10 to -2 4/10 = 1/8 increase in the resulting division of 474ml divided by 8ml

Answer:4.8 slices

Step-by-step explanation:there are 8 slices in a pizza times 3 pizzas divided by 5 friends

Each of the 5 friends gets 0.6 of a pizza when they evenly divide 3 large pizzas.

When 5 friends go out to lunch and order 3 large pizzas, dividing the pizzas evenly, we can calculate the amount of pizza each friend got. To start, we need to determine the total amount of pizza available in terms of 'pizza units'. Since there are 3 pizzas and 5 friends, we divide the pizzas into 5 equal parts. This means that each of the 3 pizzas is divided into 5 slices (assuming each pizza can be divided into equal parts).

We can represent this as a fraction where the numerator is the total number of pizzas (3) and the denominator is the number of friends (5). So, each friend gets
3/5 of a pizza. Now, converting that fraction into a decimal, we divide the numerator by the denominator. Thus, 3 divided by 5 equals 0.6. Therefore, each friend gets 0.6 of a pizza as a decimal.

3. 3/4<0.8

To complete the table of equivalent ratios, we established a simplified ratio of 1 month to 5 lb from the given information, then we used this to calculate the missing values: in 2 months the weight is 10 lb, corresponding to 20 lb there are 4 months, and in 6 months the weight is 30 lb.

To find the missing numbers in the table of equivalent ratios, we need to look for a pattern or use cross-multiplication. We can see from the given information that in 10 months the weight is 50 lb. Using this information, we can set up a ratio comparing time to weight. Let's fill out the table with the equivalent ratios.

Step-by-step Calculation

Take the given ratio of 10 months to 50 lb. This can be simplified to 1 month to 5 lb.

Now that we have the basic ratio, we can find the missing values. For 2 months, we multiply 2 by 5 lb, giving us 10 lb for the first missing number.

To find the time that corresponds to 20 lb, we take 20 lb and divide it by 5 lb/month, giving us 4 months for the second missing number.

For 6 months, we multiply 6 by 5 lb, which gives us 30 lb for the third missing number.

Now we can fill in the table:

Time (month): 2, Weight (lb): 10

Time (month): 4, Weight (lb): 20

Time (month): 6, Weight (lb): 30

Time (month): 10, Weight (lb): 50

4.) C

Step-by-step explanation: Given that the

$8,008 for tuition and fees each year.

Room and housing are an additional $8,392 per year.

Total = 8008 + 8392 = $16400

1.) Scholarship - $1,000

Grant - $1,000

Student Loan - $4,500

Months - 42

Yearly = 42/12 = 3.5 years

Total support = 1000 + 1000 + 4500

= $6500

Savings = 16400 - 6500 = 9900

First year savings = 9900/3.5

= 2828.57 dollars

2. Scholarship - $6,000

Grant - $500

Student Loan - $4,500

Months - 24

Yearly = 24/12 = 2

Support = 4500 + 6000 + 500

= $11000

Savings = 16400 - 11000

= 5400 dollars

First year savings = 5400/2

= 2700 dollars

3.) Scholarship - $10,000

Grant - $2,000

Student Loan - $0

Months - 18

Yearly = 18/12 = 1.5

Support = 10000 + 2000 = $12000

Savings = 16400 - 12000

= 14400 dollars

First year savings = 4400/1.5

= 2933.33 dollars

4.) Scholarship - $3,000

Grant - $2,000

Student Loan - $4,500

Months - 39

Yearly = 39/12 = 3.25

Support = 3000 + 2000 + 4500

= 9500 dollars

Savings = 16400 - 9500 = $6900

First year savings = 6900/3.25

= $2123.08
