Answer:
1/7 ;
0.0034
Step-by-step explanation:
Given that:
X = 1/14, 1/7, 3/14
n = number of observations = 3
Since, probability of X is equally likely ;
P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3
The mean, m ;
Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)
= 1/42 + 1/21 + 3/42
= (1 + 2 + 3) / 42
= 6 / 42
= 1/7
The variance :
Σx²*p(x) - m²
((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2
= 0.0238095 - 0.0204081
= 0.0034014
= 0.0034
He would have to jog at least 15 minutes to burn as many in afternoon as morning
Add the exponents since it’s multiplication, so it would be 2a^7, hope this helps
The mathematical expression in this case is
(x+3)/2
Answer:
9.23 x 10^-5
Step-by-step explanation:
But the decimal point behind the first number that isn't 0
Then count how many times you moved it and that is the exponent on the ten
If you moved the decimal right, it is negative exponent
If you moved the decimal left, it is a positive exponent
