Answer:
<u>x=−44/9</u>
Step-by-step explanation:
6/54−x=5/xx
Simplifies to:
−x+1/9=5
Let's solve your equation step-by-step.
−x+1/9=5
Step 1: Subtract 1/9 from both sides.
−x+1/9−1/9=5−1/9
−x=44/9
Step 2: Divide both sides by -1.
−x/−1=44/9/−1
x=−44/9
Hi!!! So to do this problem, you need to find the mean values for each sample. I will walk you through finding the mean of sample 1: first you want to add all of the values for sample 1, which are 4,5,2,4 and 3. Once you add those values you get 18. Then you must divide that 18 by the number of terms you added. The numbers you added were 4,5,2,4 and 3 like I said earlier which is 5 numbers. You divide 18 by 5 to get your mean, which is 3.6
Answer: (B) Sample 2
sample 1 mean = 3.6
sample 2 mean = 4.2
sample 3 mean = 3.8
sample 4 mean = 4
Answer:
Mode
Step-by-step explanation:
Mean:
Before replacing = 464/8 = 58
After replacing 42 with 98 = 520/8 = 65
Mode:
Before replacing = 42
After replacing 42 with 98 = 98
Median:
25, 42 , 42 , 47, 55 , 59, 96,98
Before replacing = 47+55/2 = 51
25, 42 , 47, 55 , 59, 96,98 , 98
After replacing 42 with 98 = 55+59/2 = 114/2 = 57
Cheese sticks were 10. for dollar or 10 cents a piece (10/100 =.10 or 10 cents. now 4 for dollar or ,25 x 100 = 25 cents each (4/100). percent change
.25 - , 10 =.15
,15/,25 = .60
.60 x 100 = 60%
Using Visual inspection, the model which fits the data in the distribution better is the power function.
The power and linear functions can of the data can both be modeled using technology,
<u>Using Technology</u> :
The power function in the form 
which models the data is 
The linear function in the form 
which models the data is 
- Where A = intercept and B = slope
- From the model, correlation coefficient given by the power and linear models are 0.999 and 0.986 respectively.
- Hence, the power model is a better fit for the data than the linear model.
Therefore, Inspecting the models visually, the power function fits the data better as the points on the curve are closer to the regression line than on the linear model.
