Answer:
x ≤6
Step-by-step explanation:
no more than means you can have 6 or less
x ≤6
Using the t-distribution, it is found that the 95% confidence interval for the mean number of people the houses were shown is (20.1, 27.9).
We have the <u>standard deviation for the sample</u>, hence the t-distribution is used to build the confidence interval. Important information are given by:
- Sample mean of .
- Sample standard deviation of .
- Sample size of
The confidence interval is:
In which t is the critical value for a <u>95% confidence interval with 23 - 1 = 22 df</u>, thus, looking at a calculator or at the t-table, it is found that t = 2.0739.
Then:
The 95% confidence interval for the mean number of people the houses were shown is (20.1, 27.9).

Answer:
A. x = 3.03
B. x = 4/3
Step-by-step explanation:
A. 2000 (x-0.03) = 6000 is quickly simplified byu dividing both sides by 2000:
(x - 0.03) = 3. Removing the parentheses, we get: x = -0.03 = 3, or x = 3.03.
B. The distributive property is the faster method here. We determine that the LCD is 12 and multiply both sides of this equation 1/4 (4+x) = 4/3 by 12:
3(4 + x) = 16
and then carry out the indicated multiplication: 12 + 3x = 16, or
3x = 4, or x = 4/3
Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
⇔ and = 1
Substitute the values of x into
x = 0 → = 1 ⇒ a = 1
x = 2 → = = , hence
b =
x = 4 → = = , hence
c =
For this case we have:
10 scented markers: Column 1, row 3.
6 are permanent markers: Column 1, row 1
Half of the unscented markers are erasable: (1/2) * 30 = 15 Column 2, row 2.
Therefore, the selected table corresponds to the attached image.
