Wednesday 4 1/8
Friday 8 1/2
Saturday 7 7/8
Sunday 5 3/4
A. $287.98
B. $289.43

Answer:
D
Step-by-step explanation:
For starters, add the hours Ellie worked last week:
4 1/8 + 8 1/2 + 7 7/8 + 5 3/4 = 26.25
Multiply the hours she worked with the amount of money she earns per hour:
26.25 × $11.35 = $297.9375
Now, round your answer to the nearest cent, which would be $297.94

find the y-coordinate of the point shown in the graph.
Question content area bottom left
The y-coordinate of the point is
How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

which inequality is true 1.5 > 2 1/2, 1/2 > 0.5, -2.5 > -1.5, -3 1/2 > - 4.5
Answer: D
Step-by-step explanation:
(A. 1.5 > 2 1/2
(B. 1/2 > 0.5
(C. -2.5 > -1.5
(D. -3 1/2 > - 4.5
Step 1: Convert everything to decimals or fractions so its easier to see and make it less likely to get the question wrong
Method #1: Fractions
1.5= 1 1/2
0.5= 1/2
-2.5= - 2 1/2
-1.5= - 1 1/2
-4.5= -4 1/2
Now we have:
(A. 1 1/2 > 2 1/2 --> This is wrong because 1 1/2 is supposed to be less than 2 1/2.
(B. 1/2 > 1/2 This is also wrong. 1/2 is equal to 1/2; they are obviously the same.
(C. -2 1/2 > -1 1/2 This is wrong because, in negative numbers, its sort of backwards. For example, -2 is actually less than -1 because its farther away from 0. But if they were normal positive numbers, 2 would be bigger. But here, -2 1/2 is less than -1 1/2.
(D. -3 1/2 > - 4 1/2 This is correct. -3 1/2 is closer to 0 than -4 1/2, so it has to be bigger.
Solving the problem this way gets me to: Answer= D
Method #2: Decimals (remember: same numbers, different way of writing them!!!)
(A. 1.5 > 2.5 False. 1.5 is less than 2.5
(B. 0.5 > 0.5 False. 0.5 is equal to 0.5
(C. -2.5 > -1.5 False. -2.5 is farther away from 0 so its actually smaller.
(D. -3.5 > - 4.5 True. -3.5 is closer to 0.
Doing it this way also leads me to Answer= D.
Hope this helps :)) Also can i please have brainiest? I worked pretty hard on this :D

Answer: 18
Step-by-step explanation:
x is the number we need to find
We have this equation :
2 ( 3x - 10 ) + 2 = 5x
= 6x - 20 + 2 = 5x
= -20 + 2 = 5x - 6x
= -18 = -1x
x = -18 ; 18
Hope it helps !
Answer: the original number is 18

on monday 72% of the class ordered lunch. which fraction shows the part of the class that ordered lunch?
The fraction showing the part of the class that ordered lunch is 18/25
What are fractions?A fraction represents equal parts of a whole, by dividing it up into equal partitions.
Each fraction has a numerator and denominator. The denominator represents the total number of parts the whole has been divided into.
Given that, on Monday 72% of the class ordered lunch we need to find the fraction showing the part of the class that ordered lunch,
So, we know that, 72% = 72 / 100
= 36/50 = 18/25
Hence, the fraction showing the part of the class that ordered lunch is 18/25

Answer:
(b) 1/3
Step-by-step explanation:
A function "zero" is a value of x that makes the value of the function be zero. It may also be called a "root" of the function. On a graph, it is an x-intercept.
The zeros are the solutions to the equation f(x) = 0. For a quadratic like the one given, there are two of them. For this function, they are distinct, so one will be larger than the other.
GraphThere are a number of ways the solutions to this equation can be found. Technology, in the form of a graphing calculator, can show you the x-intercepts easily (see attached). They are x=-2/5 and x=1/3.
FactoringWe can also factor the equation. Doing this requires that we find factors of the product (15)(-2) = -30 that have a sum equal to the coefficient of x, +1. Here are some factor pairs:
-30 = (-1)(30) = (-2)(15) = (-3)(10) = (-5)(6)
The corresponding sums are 29, 13, 7, 1. Hence the last factor pair, {-5, 6}, is the one we need.
Rewriting the 3-term polynomial to a 4-term polynomial by splitting the middle term using these factors, we have ...
15x² -5x +6x -2 = 0
Factoring pairs of terms gives ...
5x(3x -1) +2(3x -1) = 0
(5x +2)(3x -1) = 0 . . . . . . . factor out the common factor
The product of these factors can only be zero of one of them is zero. (This is the "zero product rule.") Setting the factors to zero, we find the values of x that make f(x) = 0: the zeros of the function.
5x +2 = 0 ⇒ x = -2/5
3x -1 = 0 ⇒ x = 1/3
The zeros of the function are -2/5 and 1/3.
The larger zero is 1/3.
-3 + 6x. Which expression shows the correct factorization?
Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)
Answer:
Option #4
Step-by-step explanation:
Expand option #4
=-3(1-2x)
=-3 -2x*-3
=-3+6x which is what your original equation was.

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values
