The function m(x) = x + 5/(x-1) has the same domain as the composition of functions (m.n)(x) because they both have the domain of all real numbers except 1.
Explanation:The domain of a function is the set of all possible input values (often called 'x-values') which will give valid output values. In other words, it's all the values x can take on. The function m(x) = x +5/(x-1) will be undefined when the denominator equals zero, so x cannot equal 1. Therefore, the domain of m(x) is all real numbers except 1.
On the other hand, the function n(x) = x - 3 doesn't have any restrictions and can take on all real numbers. However, (m.n)(x) refers to a composition of functions, specifically m(n(x)). This will inherit the domain restrictions from m(x). Therefore, the function that has the same domain as (m.n)(x) is m(x) because the composition will allow inputs for all real numbers except 1, as dictated by m(x).

The measure of ECD is 35. What is the measure of EOD?
Answer is 70
Angle *2 = 35*2 = 70
The measure of angle EOD, formed by arc ED at the center O, is 70 degrees, given that angle ECD on the same arc is 35 degrees.
let's break down the step-by-step calculation for finding the measure of EOD, given that ECD is 35 degrees:
Recall that for any angle formed by an arc at the center of a circle (EOD in this case), it is twice the measure of the angle formed by the same arc at any point on the circumference (ECD).
Given that ECD is 35 degrees, we will use this information to find the measure of EOD.
Apply the rule that EOD = 2 × ECD.
Substitute the value of ECD into the formula: EOD = 2 × 35.
Calculate the result: EOD = 70 degrees.
Therefore, the measure of EOD, which is the angle made by the arc ED at the center O, is 70 degrees.

Which measure of central tendency is least appropriate for describing the given data set?
6, 6, 6, 7, 8, 8, 29
mode
median
mean
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
6, 6, 6, 7, 8, 8, 29
We will calculate the measures of central tendency:
1) Mode - the most occurring element in the data set.
So, Mode = 6
2) Median - the middle value of organised data set
So, Median = 7
3) Mean - the average of all data set
So, Mean = [tex]\dfrac{6+6+6+7+8+8+29}{7}=\dfrac{70}{7}=10[/tex]
So, we can see that Mode and Median are giving the closest value to each other, whereas Mean is giving the farthest value as compared to rest.
Hence, Mean is the least appropriate for describing the given data set.
Thus, Third option is correct.

Based on data set shown which of the following is a true statement? -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3. Mean = mode, mean less than median , mode less than median
Answer:
"Mean = Mode"
Step-by-step explanation:
Let's find the mean, median, and mode of the number set.
-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
Mean:
this is the average. We add up all of the numbers and divide by the number of numbers (11).
Mean = [tex]\frac{-1+-1+0+1+1+1+1+2+2+2+3}{11}\\=\frac{11}{11}\\=1[/tex]
the mean is 1
Median:
this is the "middle" number when arranged from least to greatest. From 11 numbers, the 6th number is the middle one. We can see from the arrangement below, that "1" is the middle number.
the median is 1
Mode:
this is the number that occurs the "most". Looking at the numbers, "1" occurs 4 times, which is the most. So
mode is 1
From the 3 choices, the first choice is right "mean = mode".

Working alone, Pablo can put up a tent in 12 minutes. His mom can put it up by herself in 4 minutes. How many minutes would they take to put up the tent working together?
Pablo amd his mom would take Eight minutes
Final answer:
Pablo and his mom would take 3 minutes to put up the tent working together, as they combine their work rates to determine their joint effectiveness.
Explanation:
To determine how many minutes Pablo and his mom would take to put up the tent working together, we can use the concept of combined work rates. Pablo can put up a tent in 12 minutes and his mom can do it in 4 minutes. We calculate their combined work rate by adding the reciprocal of each person's time because working together means their rates add up.
Pablo's rate is 1 tent per 12 minutes, or 1/12 tents per minute. His mom's rate is 1 tent per 4 minutes, or 1/4 tents per minute. Combined, their rate is (1/12) + (1/4) tents per minute.
First, find a common denominator for the fractions, which would be 12 in this case, so we get:
(1/12) + (3/12) = 4/12
Therefore, their combined rate is 4/12 or 1/3 tents per minute. To find out how long it would take them to set up one tent, we take the reciprocal of the combined rate. Thus, 1 tent would take them 1/(1/3) minutes, or simply 3 minutes.
Working together, Pablo and his mom can put up the tent in 3 minutes.

You're asking, 2s=7+s and to solve for S.
Now first, simplify both sides of the equation.
2s=s+7
Then, subtract s from both sides.
2s−s=s+7−s
Simplify to get 7.

Step-by-step explanation:
This question is asking to find the inverse of the equation therefore you will have to interchange x and y
ie : x= -2y-4
THEN solve for y ( perform opposite operation )
x = -2y -4
(take -4 to the other side ) [it will be a +4 ]
x+ 4 = -2y

Final answer:
To find the inverse function of f(x) = -2x - 4, switch x and y and solve for the new y to get the inverse function f¹(x) = -0.5x - 2.
Explanation:
The question asks to find the inverse function of f(x) = -2x - 4. To find the inverse, we switch the roles of x and y in the equation and solve for the new y. Here are the steps:
Write the function as y = -2x - 4.
Swap x and y to get x = -2y - 4.
Solve for y to find the inverse function. Add 4 to both sides to get x + 4 = -2y, and then divide by -2 to find y = -0.5x - 2.
Therefore, the inverse function, f⁻¹(x), is y = -0.5x - 2.

Convert the angle 0=133π/72 radians to degrees
The result is 332.5 degrees.
To convert an angle from radians to degrees, we use the conversion factor that 1 radian = 180/π degrees. In this case, the angle is 133π/72 radians.
So, to convert 133π/72 radians to degrees, we multiply by the conversion factor:
(133π/72) * (180/π) degrees.
Solving this gives us the angle in degrees:
133 * 180 / 72 = 332.5 degrees.

Jade can buy a maximum of 6 magazines or 2 pies with her $24 weekly budget. The slope of her budget constraint is -2, representing the trade-off between pies and magazines. The opportunity cost of purchasing a pie is 3 magazines.
Jade has a weekly budget of $24, which she allocates between magazines and pies. Let's address the questions one by one:
Magazines: If the price of a magazine is $4 each, Jade can buy 6 magazines in a week since $24 divided by $4 equals 6.Pies: If the price of a pie is $12, Jade can purchase 2 pies in a week, as $24 divided by $12 equals 2.Budget constraint: On a graph with pies on the horizontal axis and magazines on the vertical axis, Jade's budget constraint would be a straight line starting at 6 magazines (if she buys 0 pies) and ending at 2 pies (if she buys 0 magazines). The slope of this budget constraint is -2 (the price of a pie divided by the price of a magazine).Opportunity cost: The opportunity cost of purchasing one pie is the number of magazines she has to give up, which is 3 magazines ($12/$4).graph x = -2

Explain how direct variation equations and inverse variation equations are different.
Answer:
For direct variation, use the equation y = kx, where k is the constant of proportionality. For inverse variation, use the equation y = k/x, again, with k as the constant of proportionality. These problems might use the word 'proportion' instead of 'variation,' but it means the same thing.
Step-by-step explanation:
Final answer:
Direct and inverse variation equations have distinct relationships between variables: direct variation involves both variables increasing at a constant rate, while inverse variation involves one variable decreasing as the other increases.
Explanation:
Direct variation equations and inverse variation equations are different in their structures and relationships between variables. In direct variation equations, as one variable increases, the other also increases at a constant rate, while in inverse variation equations, as one variable increases, the other decreases at a constant rate.
For example, in a direct variation equation like y = kx, as x increases, y increases at a constant rate determined by k. In contrast, in an inverse variation equation like y = k/x, as x increases, y decreases at a constant rate determined by k.
