Divide the sum of 13/5 and -12/7 by their difference
Answer to these fraction is 31/151
Describe fraction.
Any numerical value that is not a whole number is referred to as a fraction. It symbolizes a portion of something or several portions of something. The numerator and the denominator are the two components of a fraction. The denominator indicates how many equally sized pieces make up a whole, whereas the numerator indicates how many equally sized parts are picked from the whole or collection.
To divide a fraction, all you need to do is flip its numerator and denominator, multiply the outcome by the other fraction, and simplify1.
In light of this, we have:
SUM:
(13/5) + (-12/7) = (13× 7 + -12 ×5) / (5 ×7)
= (91 - 60) / 35 = 31/35
DIFFERENCE:
(13/5) - (-12/7) = (13× 7 - -12× 5) / (5× 7)
= (91 + 60) / 35 = 151/35
Dividing these two fractions:
(31/35) ÷ (151/35) = (31/35)×(35/151) = 31/151

An equation to model the relationship between the number of weeks, x, and the number of site visits, f(x) is 4800 = a(1.5)^x.
He found that before launching the new marketing plan, there were 4,800 visits.
Over the course of the next 5 weeks, the number of site visits increased by a factor of 1.5 each week.
Over the course of the next 5 weeks, initial visitor at x = 0, 4800
Increasing factor = 1.5
Equation of the model is given as:
f(x) = a(b)^x
From the question b = 1.5
Now the equation of model is:
f(x) = a(1.5)^x
At x = 0, f(x) = 4800

1. Calculate the slope of the trend line. (Choose two points on the line and find vertical change over horizontal change.)
2. Using the slope and y-intercept, write the equation of the trend line (y = mx + b).
3. Choose a "calories from fat" value that is not in your collected data set and that is at least 10 fat calories away from any collected value. Use the equation calculated in step to predict the number of fat grams in an item having that number of fat calories. Be sure to show your work.
4. Search for an item in a fast food menu having the same number of fat calories as the one you chose above. (If you cannot find the exact value, get as close as you can.) Compare the calculated value from step VI to this actual value. Explain why (or why not) you would have expected your prediction (calculated value) to be close to the actual value.
The regression line is y = 10x + 300, and the value of calories is 90 and when x = 14 the value of y = 440 from the regression line, but the actual value is 330.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph.
It's a kind of linear regression that uses scatter data to figure out the best way to define the dot's relationship.
From the data given, we can write the slope and y-intercept form:
y = mx + b
here, m = 10 and b = 300
y = 10x + 300
The number of fat grams in an item has that number of fat calories.
As we have the regression line:
y = 10x + 300
Put x = 1 in the regression line:
y = 10(1) + 300
y = 310 calories
For x = 14
y = 10(14) + 300 = 440
But the actual value from the graph is 330.
Thus, the regression line is y = 10x + 300, and the value of calories is 90 and when x = 14 the value of y = 440 from the regression line, but the actual value is 330.

group of six software packages available to solve a linear programming problem have been ranked from 1 to 6 (best to worst). an engineering firm, unaware of the rankings, randomly selects and then purchases three of the packages. let y denote the number of packages purchased by the firm that are ranked 3, 4, 5, or 6. give the probability distribution for y.
The probability distribution for y is as follows:
P(y = 0) = 1/60,
P(y = 1) = 33/60,
P(y = 2) = 20/60,
P(y = 3) = 12/60.
To find the probability distribution for y, we need to determine the possible values for y and their corresponding probabilities.
1. First, let's determine the possible values for y. Since the engineering firm randomly selects and purchases three packages out of six, y can take on values from 0 to 3.
2. If y = 0, it means none of the packages purchased by the firm are ranked 3, 4, 5, or 6. The probability of this happening is the probability of selecting three packages from the top two ranks (1 and 2), which is (2/6) * (1/5) * (1/4) = 1/60.
3. If y = 1, it means exactly one package purchased by the firm is ranked 3, 4, 5, or 6. The probability of this happening is the probability of selecting one package from the top two ranks (1 and 2) and two packages from the bottom four ranks (3, 4, 5, and 6). There are three possible scenarios: (2/6) * (4/5) * (3/4) = 12/60, (2/6) * (3/5) * (4/4) = 12/60, and (2/6) * (3/5) * (3/4) = 9/60. The total probability is 12/60 + 12/60 + 9/60 = 33/60.
4. If y = 2, it means exactly two packages purchased by the firm are ranked 3, 4, 5, or 6. The probability of this happening is the probability of selecting two packages from the top two ranks (1 and 2) and one package from the bottom four ranks (3, 4, 5, and 6). There are three possible scenarios: (2/6) * (1/5) * (4/4) = 8/60, (2/6) * (1/5) * (3/4) = 6/60, and (2/6) * (1/5) * (3/4) = 6/60. The total probability is 8/60 + 6/60 + 6/60 = 20/60.
5. If y = 3, it means all three packages purchased by the firm are ranked 3, 4, 5, or 6. The probability of this happening is the probability of selecting three packages from the bottom four ranks (3, 4, 5, and 6), which is (4/6) * (3/5) * (2/4) = 12/60.
Therefore, the probability distribution for y is as follows:
P(y = 0) = 1/60,
P(y = 1) = 33/60,
P(y = 2) = 20/60,
P(y = 3) = 12/60.

Answer:

Step-by-step explanation:
1 hexagon = 6
2 hexagons = 10
3 hexagons = 14
Based on the pattern shown above +4 you can create an equation from this to help support finding the amount.
y = 4x + 6
y - total amount
4x - amount that is added by
6 - initial amount for 1 hexagon
Based on this you plug in 12 into x and you will find the answer:
y = 4(12) + 6
= 48 + 6
= 54
If you need to check the work honestly drawing it out, but this equation can also be supported based on the 3rd diagram of hexagon, where the initial is 6 and then 4 are added each time afterwards!!!
what is the horizontal asymptote of the function f (x) = startfraction (x minus 2) over (x minus 3) squared endfraction?y = 0y = 1y = 2y = 3
The horizontal asymptote of the function f(x) = (x - 2)/(x - 3)^2 is y = 0.
To determine the horizontal asymptote of a function, we need to examine the behavior of the function as x approaches positive or negative infinity. In this case, as x becomes very large or very small, the terms involving x-2 and x-3 become insignificant compared to the higher power of (x-3) squared in the denominator.
As x approaches positive or negative infinity, the (x - 2) term in the numerator does not affect the overall behavior of the function. However, the (x - 3)^2 term in the denominator becomes dominant.
Since (x - 3)^2 will always be positive, the function is always positive or zero. Therefore, as x approaches positive or negative infinity, the function approaches zero or a positive value but never crosses the horizontal line y = 0. Hence, the horizontal asymptote of the function f(x) = (x - 2)/(x - 3)^2 is y = 0.

c. The IQR is the best measurement of spread for games and movies.
d. The standard deviation is the best measurement of spread for games and movies.
a) 'The IQR is a better measure of spread for movies than it is for basketball games' best describes how to measure the spread of the data
According to the information provided, the box plots for movies and basketball games indicate that both have the same range of attendance data, with a minimum of 60 and a maximum of 150. However, when comparing the interquartile ranges (IQRs) of the two box plots, it can be seen that the IQR for movies is smaller than the IQR for basketball games.
The IQR represents the middle 50% of the data, and the smaller IQR for movies suggests that the attendance data for movies is more closely clustered around the median than the attendance data for basketball games.
