Answer:
34.134%
Step-by-step explanation:
Given :
Normal distribution ;
Mean, m = 100 ; Standard deviation, s = 10
Percentage score between 90 and 100
P(90 ≤ x ≤ 100)
Recall : Zscore = (x - m) / s
P[(90 - 100) / 10 ; (100 - 100) / 10]
P[(10/10 ; 0 / 10)]
P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%
45°
90-45=45°
For what value of B is the trigonometric function considered an odd function? y=cosB(x-c)
1/4
Whats the question
x = 11
y = 3
4y+1=6y-5
-4y -4y
+1 =2y-5
+5 +5
6/2=2y/2
3=y
2x-4= 18
+4 +4
2x/2 = 22/2
x=11
