Brian makes four serving of pineapple-mango juice shown in the table. Does the table of ratios show equivalent proportional relationships?
Answer:
turn the mix numbers into improper fractions. then take two fractions and multiply the numerator by the other fractions denominator. If they all result with the same name it’s proportional, if not then u get the idea
Step-by-step explanation:
oh yuh
No, the measurements in the table given are not showing equivalent proportional relationships.
What are proportional relationships?Proportional relationships are relationships between two variables where their ratios are equivalent.
Given is a table showing, Proportional relationships for four serving of pineapple-mango juice,
Pineapple juice Mango juice
2 [tex]1\frac{1}{9}[/tex]
[tex]2\frac{1}{2}[/tex] 4
3 [tex]4\frac{1}{2}[/tex]
Checking for proportional relationships;
1) Pineapple juice / Mango juice = 2 ÷ 10/9 = 9 / 5
2) Pineapple juice / Mango juice = 5 / 2 ÷ 4 = 5 /8
3) Pineapple juice / Mango juice = 3 ÷ 9/2 = 2 / 3
As we see, that all three proportions are not equal.
Hence, we can that the given relations are not equivalent proportional relationships.

Find the value of m and n so that tha function . = + −x a solution of Given differential equations ′′ − ′ − = 0 () = , ′() = 2
Question:
Determine the value of m and n so that the following system of linear equation have an infinite number of solutions.
[tex](2m-1)x+3y-5=0[/tex]
and
[tex]3x+(n-1)y-2=0[/tex]
Answer:
[tex]m=\frac{17}{4}[/tex]
[tex]n = \frac{11}{5}[/tex]
Step-by-step explanation:
Given
[tex]3x+(n-1)y-2=0[/tex]
[tex](2m-1)x+3y-5=0[/tex]
Rewrite both equations:
[tex]3x + (n - 1)y = 2[/tex]
[tex](2m - 1)x + 3y = 5[/tex]
For the expression to have a solution, the following condition must exist:
[tex]\frac{3x}{(2m - 1)x} = \frac{(n-1)y}{3y}= \frac{2}{5}[/tex]
Split to 2
[tex]\frac{3x}{(2m - 1)x} = \frac{2}{5}[/tex]
[tex]\frac{(n-1)y}{3y}= \frac{2}{5}[/tex]
Cross Multiply
[tex]5 * 3x = 2 * (2m - 1)x[/tex] -- (1)
[tex]5 * (n -1)y = 2 * 3y[/tex] -- (2)
Solving (1)
[tex]5 * 3x = 2 * (2m - 1)x[/tex]
Divide both sides by x
[tex]5 * 3 = 2 * (2m - 1)[/tex]
Open bracket
[tex]15 = 4m - 2[/tex]

[tex]4m = 15+2[/tex]
[tex]4m= 17[/tex]
Make m the subject
[tex]m=\frac{17}{4}[/tex]
Solving (2)

The data shows the number of years that 30 employees worked for nc insurance company before requirement. _____ is the population mean for the number of years worth, and _____ % of the employees worked for the company for the last 10 years. (round off your answers to the nearest integer.)
Answer:
population mean: 14
employees worked: 73%
Step-by-step explanation:
The mean is found by adding the years of service and dividing by the number of employees. The total years of service is 417, so the average is ...
average years worked = 417/30 = 13.9 ≈ 14 . . . years
__
The percentage of employees that have worked there at least 10 years is found by counting the number with 10 or more years of service and dividing that count by the total number of employees. The result is then expressed as a percentage.
(10 years or over)/(total number) = 22/30 = 0.73_3 (a repeating decimal) ≈ 73%
_____
Comment on the working
A spreadsheet can be helpful for this. It has a function that can calculate the mean for you. Sorting the years of service into order can make it trivially easy to count the number that are 10 or more, or you can write a function that will do the count for you. (Also, less than 10 means the years are a single digit. There are 8 single-digit numbers in your list.) The hard part is copying 30 numbers without error.

Matt is painting a mural on a 1-square meter section of a wall. He has completed a rectangular part of the mural that is four sixths of a meter wide and two fifths of a meter tall. What part of the mural has been completed?
Answer:
26.66%
Step-by-step explanation:
In order to calculate how much of the mural has been completed, we need to find the area of the rectangle. Since both the length and the width have been provided we simply multiply these values together and to find the amount of the mural that has been completed...
[tex]\frac{4}{6} * \frac{2}{5} = \frac{8}{30}[/tex] or 0.2666[tex]m^{2}[/tex]
We can see that 0.2666[tex]m^{2}[/tex] have been completed. Now we can divide this by the total size of the mural to calculate the percent that is completed.
0.26666[tex]m^{2}[/tex] / 1[tex]m^{2}[/tex] = 0.2666 ... multiply by 100 to get percent value
0.2666 * 100 = 26.66%
Finally, we can see that a total of 26.66% of the mural has been completed.
Answer: 8/30 (or eight thirteenths) in fraction form, and 26/66% in percentage form :)

The shape is skewed to the left since there are more numbers on the right than on the left (i.e., there is a tail on the left).
All but three numbers are less than 70. Only one number is in the 60s and no numbers are in the 50s. The numbers 45 and 48 are very likely to be outliers. He might have injuries in these seasons that caused him to play fewer games than usual.
