Answer:
Z = 45 degrees
Step-by-step explanation:
the angle is still an acute angle but it is not a right angle so it must be 45 according to my calculations. plz mark brainliest
Slope intercept form: y = 3/4 x - 7
Point slope form: y + 7 = 3/4 (x+0)
Plug in 0 into x of the equation y=2x+3, solve it, then take that answer and use that as your y then plug in the answer for y and solve for x. (i realized i am very bad at explaining this over this. Sorry I tried)
Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:

The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
