Answer:
First one
Step-by-step explanation:
5sin(3pix)+8=4
5sin(3pix) = -4
sin(3pi x) = -0.8
Basic angle: sin^-1(0.8) = 0.927295218
3pi x = pi+0.927295218, 2pi-0.927295218
3pi x = 4.068887872, 5.355890089, 4.068887872 + 2pi, 5.355890089 + 2pi, 4.068887872 + 4pi, 5.355890089 + 4pi,
x = above values/3pi
x = 0.43217, 0.568, 1.0984, 1.235, 1.765, 1.9016
8.50+23.25+18+10.75 +x /5=14
Multiply both sides by 5.
60.50. + x =70
Subtract 60.50 from both sides
X= 9.50. The other candy bar costs 9.50

Step-by-step explanation:
Represent the probability that a graduate finds a job with p
Required
Determine the probability that at least 1 of 7 gets a job.
In probability:
So, we calculate the probability that none of the 7 gets a job.
Represent the probability that a graduate will not get a job with q.
Represent as decimal
The probability that none of the 7 will get a job is
i.e.
So, we have:
Substitute 0.45 for q
