Answer:
it has been found that 85.6% of all enrolled college and university students in the U.S. are undergraduates. A random sample of 500 enrolled college students in a particular state revealed that 420 of them were undergraduates. Is there sufficient evidence to conclude that the population differs from the national percentages? Use a = 0.05
Answer:
3x^2-15y-10x
Step-by-step explanation:
2x-12x-8y+7y+3x^2
-10x-15y+3x^2
3x^2-15y-10x
2462 / 40 = 61.55
there are about 62 40s in 2462.
Answer:
( x + 2 )² + ( y - 4 )² = 36
Step-by-step explanation:
Standard equation of a circle - ( x - h )² + ( y - k )² = r²
where r = radius and center is at ( h , k )
The given center is ( -2 , 4 )
Thus h = -2 and k = 4
and the given radius is 6
Thus, r = 6
that being said, we plug in the given values into the standard equation
( x - ( - 2 )² + ( y - 4 )² = 6²
Finally we simplify
In - ( -2 ) the two negative signs cancel out and it turns into + 2
6² = 36
The final equation of the circle is ( x + 2 )² + ( y - 4 )² = 36
Answer:
about 18.8496 ft squared
Step-by-step explanation:
find the area of the garden and the path together. About 69.115 ft squared.
Then find the area of the garden. About 50.2654 ft squared. Then subtract.
