the data shows the length and weight of a species of fish based on the data
which is closest to the length of a fish that weighs 4.2 pounds
Answer:
36.5 inches
Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Pick any two corresponding points from the table
So, we have:
[tex](x_1,y_1) = (8,1.21)[/tex]
[tex](x_2,y_2) = (12,1.63)[/tex]
So:
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{1.63 - 1.21}{12 - 8}[/tex]
[tex]m =\frac{0.42}{4}[/tex]
[tex]m =0.105[/tex]
The linear equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 0.105 * (x - 8) + 1.21[/tex]
Open bracket
[tex]y = 0.105x - 0.84 + 1.21[/tex]
[tex]y = 0.105x + 0.37[/tex]
To get the length closest to 4.2lb,
we set [tex]y = 4.2[/tex]
Then solve for x
So, we have:
[tex]y = 0.105x + 0.37[/tex]
[tex]4.2 = 0.105x + 0.37[/tex]
Collect like terms
[tex]0.105x= 4.2 - 0.37[/tex]
[tex]0.105x= 3.83[/tex]
Solve for x
[tex]x= 3.83/0.105[/tex]
[tex]x\approx 36.5[/tex]

What are five steps for solving percentage problems?
Answer:
Find the percentage of the original or real number.
Multiply the final number by 100.
Divide the result of the multiplication by the percentage.
Have a great day
The proportion of the original or true number is then added 100 to the final figure.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Let's suppose it is required to find the x percentage of y:
First step:
= x% of y
Second step:
= (x/100)y
Third step: Divide x by 100
= 0.01xy
Fourth step: Multiply the remaining term(0.01x and y).
= 0.01xy
The fifth step: Round off if required
= 0.01xy %
Calculate the proportion of the original or true number.
Add 100 to the final figure.
Subtract the percentage from the multiplication result.
Thus, the proportion of the original or true number is then added 100 to the final figure.

What is the interquartile range (IQR) of the data set represented by this box plot?
Answer:
The IQR (interquartile range) of the data set represented by this box plot is 22 units.
Step-by-step explanation:
Each number of the data set represented as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is called the minimum. The highest number there (the last number), 75, is called the maximum. The second number there, 45, is called the lower quartile. The third number there, 50, is called the median or middle quartile. The fourth number there, 67, is called the higher quartile. In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
67 (highest quartile) - 45 (lower quartile) = 22 (interquartile range)
Therefore, the IQR (interquartile range) of the data set represented by this box plot is 22 units.
Answer:
It’s 22

If x and x+ 10 are a pair of adjacent angle find them
Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
If they will be pair of angles on the same line , then their sum will be 180° .=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
Hence the two angles are 85° and 95° .Convert the following radian measure to degrees.
0.9102
52.151°
0.9102rad × 180/π = 52.151°

To make a number pattern yuan used the rule add 5 with whole numbers as the startjng point. Which stament must be true about yuans list of numbers?☜︎
Answer:
All elements of the dataset will be whole numbers
Step-by-step explanation:
Given
[tex]Rule \to Add\ 5[/tex]
[tex]Start = n[/tex] ---- whole number
Required
A true statement about the list
If the starting point is n, then the list elements are as follows:
[tex]n , n + 5, n + 10, n + 15,....[/tex]
Also, since n is a whole number and 5 (the rule) which is added to the dataset is also a whole number;
Then the other elements of the dataset will be whole numbers

Solve: 2x - 3y = 9 and x + 2y = 1
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )

A deli orders ham and turkey. The ratio of the number of ham slices to the number of turkey slices is 2:3. What is the ratio of the number of turkey slices to the total of ahem and turkey slices
Answer:
3 :5
Step-by-step explanation:
A deli orders ham and turkey.
The ratio of the number of ham slices to the number of turkey slices is 2:3.
Hence:
Ham slices: Turkey slices
2:3
Sum of proportion = 2 + 3 = 5
Ratio of turkey slices = 3
Ratio of the total of ham and turkey slices = sum of proportion = 5
Therefore, the ratio of the number of turkey slices to the total of ham and turkey slices is
3:5
