Answer:
just post them all in one question instead of a ton of different questions. it's annoying.
Step-by-step explanation:
This would be a lot easier with the figure.
Four equal spaces means quarters.
A is 1 mark to the left of 0, so 1/4 to the left of 0. That's -1/4
Answer: Negative one-fourth
Answer:
a

b

Step-by-step explanation:
From the question we are told that
The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes
Generally the cumulative distribution function for continuous uniform distribution is
Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

=> 
Generally the average time required to learn the procedure is mathematically represented as

=> 
=> 
Answer:
$4125.
Step-by-step explanation:
When solving for the principal we still need to use the formula
.
Let's take all the variables that we do have available and list them out.
A = $4369.20
r = 3.3% or 0.033
n = 4 (Quarterly)
t = 21 months or 1.75 years
Now we can substitute the values and solve for the principal.





Now we need to divide both sides with 1.05919912849 to get the principal.

P = 4125.00339406 or $4125.
To check for our answer, we can simply substitute the values including the principal and excluding the total.
