10466.6667
that rounds up to 10,467.
I could be wrong though!
hope this helps! :)
Answer:
Yes
Step-by-step explanation:
Given that your classmate suggests that the margin of error in the interval could be reduced if the confidence level were changed to 90% instead of 95%.
This is a true statement
Reason:
Confidence interval = mean±margin of error
margin of error = Critical value * Std error
Thus we have the higher the margin of error the wider the confidence interval.
And the higher the critical value the higher the margin of error.
In other words when confidence level is reduced from 95% to 90% we get reduced critical value and as a result narrower confidence interval.
True statement
4.25×8=34 so the sum of the eight numbers is 34. now do 34-7-4-5-6-3-4-2=3. the number on the bottom card is 3
The features in a function can be used to describe real-world events. The features and their match are:
- <em>domain: all possible lengths of the tomato patch</em>
- <em>y - intercept: area of the bell pepper patch when the length of the tomato patch is 0
</em>
- <em>x - intercept: length of the tomato patch when the area of the bell pepper patch is 0</em>
- <em>range: all possible areas of the bell pepper patch</em>
<em />
For Melissa's garden, the input and output variables are:
- <em>Input: tomato patch</em>
- <em>Output: bell pepper patch</em>
The range is the list of possible output values, while the domain is the list of possible input values.
This means that: the range is all possible areas of the bell pepper patch while the domain is all possible lengths of the tomato patch
Also, the x and y intercepts are when the values of the output and input variables are 0, respectively.
Using the above comparison;
The y - intercept is the area of the bell pepper patch when the length of the tomato patch is 0, while the x - intercept is the length of the tomato patch when the area of the bell pepper patch is 0.

3x + 2(4 + 6x) = 113
3x + (4 * 2 + 6x * 2) = 113
3x + (8 + 12x) = 113
Reorder the terms:
8 + 3x + 12x = 113
Combine like terms: 3x + 12x = 15x
8 + 15x = 113
Solving
8 + 15x = 113
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 15x = 113 + -8
Combine like terms: 8 + -8 = 0
0 + 15x = 113 + -8
15x = 113 + -8
Combine like terms: 113 + -8 = 105
15x = 105
Divide each side by '15'.
x = 7

x = 7</span>
