Answer:
40°
Step-by-step explanation:
Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.
Volume of a cone = [(pi)r^2(h)]:3 = [3.14 (25m^2)(12m)]:3 = 314in^3.
Answer:
the answer is A
Step-by-step explanation:
Answer: B. 0.4772
Step-by-step explanation:
Given : The mean time : 
Standard deviation : 
Let X be the service time of a randomly selected customer.
Assuming a normal distribution, the value of z-score is given by :-
For x = 64
For x = 100
The p-value =
Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772
Turn 1% into decimal which is 0.01.
5,000×0.01=50
12 months=1 year
50×12=600
600+5,000=5,600
Answer: He will have $5,600 in his account at the end of one year.
Hope this helps!!!
