Answer:
4.2
Step-by-step explanation:
cos65°= adj/hyp
cos65°= x/10
x= cos65° * 10
*make sure your calculator is in degree mode

120 because its a circle and 360-240 =120
Answer:
The mean is 0.54 and the standard deviation is 0.0135.
Step-by-step explanation:
i) the mean of the sampling distribution is 0.54
ii) the mean for the sampling distribution, p = 0.54
iii) therefore for the sampling distribution, q = ( 1 - 0.54) = 0.46
iv) the sample size of the distribution, n = 1356
v) 
Answer:
(2x - 5) (x + 4)
Step-by-step explanation:
X - y/2 = 4
x - 4 = y/2
2(x - 4) = y
2x - 8 = y.....so we sub in 2x - 8 in for y in the other equation
3x - 2y = 11
3x - 2(2x - 8) = 11
3x - 4x + 16 = 11
-x = 11 - 16
-x = -5
x = 5
2x - 8 = y
2(5) - 8 = y
10 - 8 = y
2 = y
It has one solution and it is (5,2)
