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.
Answer:
Animism
Step-by-step explanation:
Animism is often a major idea or thought which is developed in a child preooperational stage according to paiget's theory of cognitive development where a child's learning is driven and derived from by symbols. At this stage, a child often relates with their toys, and other inanimate objects they come across as though they were real, manipulating and transforming them to form different things including relating with these manipulated objects like they were living. This is because at this stage, a child cannot use cognitive or logic to make distinctions.
Answer:
yes 1+1=2
Step-by-step explanation:
A=future amount
P=present amount
r=rate in decimal form
n=number of times per year to be compounded
t=time in years
so
P=200
r=0.06
n=1
t=6
evaluate to find A
A=283.704
round
A=$283.70
The answer would be A.) 0.8 !! Goodluck
