Answer:
2x+30=x+80 (corresponding angles)
2x-x=80-30
x=50
Answer:
0.13
Step-by-step explanation:
Answer:
x^2 + 10x + 25
Step-by-step explanation:
(B/2) ^2
10/2 = 5
5^2 = 25
Answer:
a. 0.6899
b. 0.1642
Step-by-step explanation:
a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:

Hence, the probability of correctly identifying the 6 matches is 0.6899
b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:

#Hence, the probability of correctly identifying the 6 matches is 0.1642
*I have used the sample size of 6(due to conflicting info/question size).
To get the pay rate you must divide the salary in the 6 weeks by 6.
108/6=18
So the pay rate for one week is $18.00
the basic person works 40 hours a week so now divide 18 by 40
18/40=0.45
So the pay rate (If she works 40 hours a week) will be $0.45 per hr.
