Answer:
B) It is irrational and equal to 
Step-by-step explanation:
The expression, 
, is an irrational expression because it contains two irrational numbers, 
and 
. Both number are not perfect square. there is no whole number that would be squared that will give you 18 nor 2.
The expression can be equals the following:
Answer:
(x -+2)² + (y - 4)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 2, 4) and r = 6 , then
(x - (- 2))² + (y - 4)² = 6² , that is
(x + 2)² + (y - 4)² = 36 ← equation of circle
Step-by-step explanation:
Percent of requests for Joseph were:
Total number of requests:
320+750+620+930+800+180=
1070+1550+980=
2620+980=3600.
Which means the percentage is:
Answer:
b. Square root of the variance
Step-by-step explanation:
The standard deviation measure how scattered the data of the set is, in other words, measure the dispersion. A low value is found when the points are close to the mean, and when the value is high the data uses a wider range of values. To calculate its value, the simple way, you need the variance because the standard deviation is the square root of the variance.
All you would have to do is take 7 and times it by 14.93
7 • $14.93= $104.51
