Answer:
30
Step-by-step explanation:
We need to find the greatest common factor of 120 and 144.
First, write the prime factorization of both:
120 = 2³×3×5
144 = 2⁴×3²
Both have 2³ and 3 in common, so the GCF is:
GCF = 2³×3
GCF = 24
So the side length is 24 cm. The number of squares along the width is:
120 / 24 = 5
And the number of squares along the length:
144 / 24 = 6
So the number of squares need to fill the entire area is 5×6 = 30. This is the least number of squares with whole-number side lengths that he can use.
Using the z-distribution, it is found that the 95% confidence interval for the true proportion of adults who said that they will travel more this year is (0.347, 0.433).
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
In which z is the z-score that has a p-value of
.
195 out of 500 people said they would take more vacations this year than last year, hence:

95% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the true proportion of adults who said that they will travel more this year is (0.347, 0.433).

Answer:
x = -3/28
Step-by-step explanation:
Start of by subtracting 3/7
7/14 - 6/14 = 1/14
-2/3x = 1/14
Divide -2/3, don't forget to reciprocate your fraction since you are dividing.
1/14 * -3/2 = -3/28
x = -3/28
