I think the correct answer among the choices listed above is option C. The only true statement is that t<span>he domain of the logarithmic function f(x) = log5x is all positive real numbers. Hope this answers the question. Have a nice day.</span>
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
<span>3 4/9 + 5 1/3
= 3 4/9 + 5 3/9
= 8 7/9
11 1/5 + 2 1/2
= 11 2/10 + 2 5/10
= 13 7/10
7 4/5 + 1 9/10
= 7 8/10 + 1 9/10
= 8 17/10
= 9 7/10
10 3/4 + 15 1/3
= 10 9/12 + 15 4/12
= 25 13/12
= 26 1/12
7 1/2 + 6 1/3
= 7 3/6 + 6 2/6
= 13 5/6</span>
#2) A. -7
you are correct
I think his -4 because the E represents 2.5
