Answer:
a) So, she can expect a 2.4 calls per hour.
b) So, the standard deviation is 0.8.
Step-by-step explanation:
We know that probability model below describes the number of repair calls that an appliance repair shop may receive during an hour.
Repair Calls 1 2 3 4
Probability 0.1 0.5 0.3 0.1
a) We calculate how many calls should the shop expect per hour.
We get:
So, she can expect a 2.4 calls per hour.
b) We calculate the standard deviation:
So, the standard deviation is 0.8.
1. x = cost of one adult ticket
y= cost of one child ticket
2x+3y=31.60
x+2y=18.60 l multiply by -2
2x+3y=31.60
-2x-6y=-37.2
-3y=-5.6
y=1.87
2x+3(1.87)=31.60
2x+5.6=31.60
2x=31.60-5.6
2x=26
x=26/2
x=13
Answer: The adult ticket is $13 and the child ticket is $1.87
First, you take 36 counters and spread them out. You then separate them into groups of 8 and any left that cannot be separated into groups of 8 are the remainders. When you do this, you will find that you are able to separate 36 into 4 groups of eight, and you will get a remainder of 4, so your answer is 4 remainder 4
A) 150 people
