Answer:
A = 2700 ft^2
Step-by-step explanation:
The area is given by
A = l*w
Convert yds to ft
1 yd = 3 ft
90 yds = 90 *3 = 270
A = 10 * 270
A = 2700 ft^2
Step-by-step explanation:
As the vertex (−2,5) and focus (−2,6) share same abscissa i.e. −2, parabola has axis of symmetry as x=−2 or x+2=0
Hence, equation of parabola is of the type (y−k)=a(x−h)2, where (h,k) is vertex. Its focus then is (h,k+14a)
As vertex is given to be (−2,5), the equation of parabola is
y−5=a(x+2)2
as vertex is (−2,5) and parabola passes through vertex.
and its focus is (−2,5+14a)
Therefore 5+14a=6 or 14a=1 i.e. a=14
and equation of parabola is y−5=14(x+2)2
or 4y−20=(x+2)2=x2+4x+4
or 4y=x2+4x+24
Answer:
3/5 of the students in the class are not in accounting majors
Step-by-step explanation:
The total number of males in the class is 3/8
3/5 of them are accounting majors
The ones who are not in accounting majors are;
3/8 - 3/5 = 9/40
The total number of female students in the class is;
8/8 - 3/8 = 5/8
1/4 of them are accounting majors
The ones who are not in accounting majors are;
5/8 - 1/4 = 3/8
Total number of students not in accounting majors;
9/40 + 3/8
= 24/40
= 3/5
Answer:
True
Step-by-step explanation:
Given that
The mean is 36
And, the standard deviation is 10
We take the sample of 16 individuals and the same would be randomly chosen
We need to find out that whether the given statement is true or false
So,
The given statement is true as the random variable means the average percent that could be consumed each day by a person
