Keisha is correct since all the points in quadrant one are positive. If the coordinates are interchanged, the x coordinate and the y coordinate will still both be positive so they will remain in quadrant 1
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
Answer:
n has to be at least 16577.
Step-by-step explanation:
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 zscore that has a pvalue of 
.
The margin of error is:
Out of n randomly selected students she finds that that exactly half attend their home basketball games.
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
About how large would n have to be to get a margin of error less than 0.01 for p
We have to find n for which M = 0.01. So
Rounding up
n has to be at least 16577.
Your answer is Y=-3/2+0 when you count the rise over run
Answer:
-11s^{5}v^{4}
Step-by-step explanation:
Use \frac{a^{m}}{a^{m}} = a^{m-n}
So you can apply here:
\frac{-11v^{6}s^{5}}{v^{2}} = -11s^{5}v^{6-2}
So your left with
-11s^{5}v^{4}
