Answer:
1) 0, 180
2) 90
3) 3pi/2
4) pi/2, -3pi/2
5) 90, 270
6) 0
7) pi
8) -2pi, 0, 2pi
Step-by-step explanation:
1) sinx = 0
x = 0, 180, 360
2) sinx = 1
x = 90
3) sinx = -1
x = 270 or 3pi/2
4) sinx = 1
x = pi/2, pi/2 - 2pi = -3pi/2
5) cosx = 0
x = 90, 360
6) cosx = 1
x = 0, 360
7) cosx = -1
x = pi
8) cosx = 1
-2pi, 0 , 2pi
Answer:
Inclusive means that we'll use the signs ≤ and ≥. Let's call the variable in our inequality as x. Therefore, the answer is -5 ≤ x ≤ -1.
Answer:
See below
Step-by-step explanation:
4 more than 3: 3 + 4 = 7
5 out of 9: 5/9
the sum of 6 and 8: 6 + 8 = 14
10 less than 14: 14 - 10 = 4
the product of 3 and 4: 3 * 4 = 12
the ratio of 2 to 3: 2/3
10 decreased by 8: 10 - 8 = 2
the quotient of 23 and 25: 23/23
3 increased by 33: 3 + 33 = 36
50% of 32: 50% * 32 = 0.5 * 32 = 16

Answer: The mean of the frequency distribution is 51.7°.
The computed mean 51.7° is greater than the actual mean 50.7° .
Step-by-step explanation:
The given table :
Low Temperature (°F) Frequency Mid -value
Class interval f x fx
40-44 2 42.5 85
45-49 7 47.5 95
50-54 9 52.5 105
55-59 5 57.5 115
60-64 1 62.5 25
The computed mean 51.7° is greater than the actual mean 50.7° .
