Step-by-step explanation:
The sum of the three angles in a triangle must be . Since this triangle has a right angle, we know that it is °, so the sum of the remaining two angles must be .
We can set up an equation for the two remaining angles to determine the value of :
It's 6 because 13 times 6 -3 is 75. i'm pretty sure that's how you would do it... lol
Answer:
ln 3
Step-by-step explanation:
3 ln 3 - ln 9
We can rewrite 9 as 3^2
3 ln 3 - ln 3^2
We know lnx^a = aln x
3 ln 3 - 2 ln 3
ln 3
14/22
well if you take the possibility and split it in half the you get your probability of it being
Answer:
0.84134
Step-by-step explanation:
Given that:
Mean, m = 70
Standard deviation, s = 10
P(x ≥ 60)
Obtain the standardized score (Zscore) :
Z = (x - m) / s
Z = (60 - 70) / 10
Z = - 10 / 10
Zscore = - 1
P(Z ≥ 1) = 0.84134 (Z probability calculator)
