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)
X<-7 so the answer would be greater*
I believe the correct answer is 365,000, since the double of those 40% is 292,000 (80%), and to find the remaining 20% you just divide 40% in half to get 73,000, adding that to 292,000 will get you 365,000, hope o helped !
The option that has the same value of theta is; D. sec theta = 3/square root of 5 and tan theta = -2/square root of 5
<h3>How to Calculate Trigonometric Functions?</h3>
We are given that;
sin θ = -²/₃
Thus, from trigonometric ratios we have;;
cos θ = -(√5)/3
Thus;
sec θ = -3/√5
tan θ = -2/√5
Thus, only option D is the correct answer.
