Answer : option B
Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)
The distance between vertex and center is 9-4 = 5
Center is (h,k) so h= 4 and k =2
focus is (h+c,k)
From the given focus (4+2sqrt5,2), c= 2sqrt(5)
Standard form of equation is
h= 4, k=2, a=5, c=2sqrt(5), we need to find out b
b^2 = 5
plug in all the values
Option B is correct
Answer:
Step-by-step explanation:
There are 10 cubes all together.
You want blue and then red with replacement.
Blue
P(B then red) = 3/10 * 4/10 = 12 / 100
12/100 reduces to 3/25
The answer is A
You can subtract 1 3/4 and 1/8.
Answer:
a
Step-by-step explanation:
Answer:
probability = 6/7
Step-by-step explanation:
a+b+c= 30 students
there are 35 students in total.
=30/35
30/35 fully simplified = 6/7
the probability that a student earns a grade of A, B, or C is 6/7.
also, 6/7 as a decimal rounded the nearest hundreth is 0.86, FYI.
