Answer:
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
(48.937 , 50.863)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given data random sample of 46 bins, the sample mean amount was 49.9 pounds and the sample standard deviation was 3.641
<em>The sample size 'n' =46</em>
<em>mean of the sample x⁻ = 49.9</em>
<em>Standard deviation of the sample S = 3.641</em>
<u>Confidence intervals:</u><em>-</em>
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
<em></em>
<em></em>
<em>Degrees of freedom = n-1 = 46-1 =45</em>
<em>The tabulated value t₀.₉₆ = 1.794 ( from t-table)</em>
<em></em>
<em></em>
(49.9 -0.9630 , 49.9+0.9630)
(48.937 , 50.863)
<u>Conclusion:</u>-
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
(48.937 , 50.863)
Answer:
125+1-12=114
Step-by-step explanation:
= 5×5×5 = 25×5 = 125
-2×6 = -12
Answer:
Kindly check explanation
Step-by-step explanation:
Give the line of best fit :
y = 1.62x + 18 ; where ;
y = wait time ; x = number of staffs available
If slope of the line is -1.62.
The slope of linear graph represents the ratio of change in the y variable and the x variable. With a slope value of - 1.62, the rate of change is negative and thus an increase in x will lead to a decrease in y. This means that for every unit increase in the number of staffs, the wait time reduces at a rate of 1.62 per unit.
Ok so first there is 44 kids who chose basketball and 28 more who chose soccer, making it basketball=44 kids and soccer=72 kids.
Then you have 15 ninth graders and when you subtract that from the 44 you have 29 tenth graders. Doing the same thing with the soccer, you have 34 ninth graders and 38 tenth graders who chose soccer.
Hope this helped
You have a system of linear equations. For solving this question, you can apply the addition method.
In this method, we try to cancel one of the variables x or y. Let`s go!
Now, you should replace the value found for x in any equation for finding y.
Answer
x=5 and y=-2
