The data value 2.5 will lie below the second quartile
Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
Answer:
I believe it's 2x²-8x + 1
Step-by-step explanation:

Answer:
B. 11.1
Step-by-step explanation:
The sequence is arithmetic, with a first term (a1) of 1.3 and a common difference (d) of 0.2.
The n-th term (an) is given by the equation ...
... an = a1 + (n -1)·d
So, the 50th term is ...
... a50 = 1.3 + (50-1)·0.2 = 1.3 +9.8 = 11.1
Answer:
the probability of a coin landing on heads 3 times in a row is 1/8 or 0.125 or 12.5%
Step-by-step explanation:
the chance of landing heads once is 1/2, for it to be 2 times in a row its 1/4, and 3 times in a row its 1/8, basically every time you want to do it in a row you multiply 1/2, so for example for this question you multiply 1/2 by however times you want the coin to land on heads in a row, (1/2) X(1/2)X(1/2)
