Answer:
0.63043
Step-by-step explanation:
Given that :
Mean = 225
Standard deviation = 45
P(x > 210) : (x - mean) / standard deviation
P(x > 210) = (210 - 225) / 45
P(x > 210) = - 0.333
P(Z > - 0.333) = 0.63043 (Z probability calculator)
Y = 32.0⁰ or 32⁰ in the nearest tenth
Step by step explanation:
sin y = <u>9</u> = 0.53
17
y = arcsin 0.53 = 32.0⁰ = 32 ⁰

Answer:
1) x ≤ -2;
2) x > 2;
3) x - 2 < 0
4) 2 ≤ x;
5)-2 < x;
Step-by-step explanation:
≤ means equal to or smaller than;
≥ means equal to or greater than;
< means smaller than;
> means greater than;
In addition, ≤ and ≥ are closed dots in the intervals. < and > are open dots in the intervals.
1) x ≤ -2; By looking at the intervals, the dot is -2, and the arrow is going to the left sides, -4, that the numbers were in a range of smaller than -2. And also because it's a closed dot, it means equal to or smaller than.
2) x > 2; The number starts in 2 with an open dot, and goes to 4, which means x in a range that greater than 2 but not equal to.
3) x - 2 < 0, we get x < 2, by plus 2 in both sides. The number starts in 2 with an open dot and goes to -4, which means x becomes smaller than 2 but not equal to.
4) 2 ≤ x; The number starts in 2 with a closed dot and goes to 4, the x is places in a number range that is equal to or greater than 2.
5)-2 < x; The number starts in -2 with an open dot and goes to 4, which means x becomes bigger than -2 but not equal to.
