in simple interest, I=PRT
I=interest
P=principal
R=rate in decimal form
T=time in years usually, but could be months or weeks, dunno
I'm assuming that the 8.75 is 8.75% or 0.0875 in decimal
so
I=PRT
we know I, P, and R, so solve for T
I=PRT, divide both sides by PR
I/(PR)=T
subsitute
I=5425.00, P=15000, R=0.0875
I/(PR)=5425.00/(15000*0.0857)=4.133333333=T
so the time is 4.13333333 units of time
Answer:
a) 0.1108
(b) 0.0173
Step-by-step explanation:
We are given that 20% of all stock investors are retired people. A random sample of 25 stock investors is taken.
Firstly, the binomial probability is given by;
where, n = number of trails(samples) taken = 25
r = number of successes
p = probability of success and success in our question is % of
retired people i.e. 20%.
Let X = Number of people retired
(a) Probability that exactly seven are retired people = P(X = 7)
P(X = 7) =
= = 0.1108
(b) Probability that 10 or more are retired people = P(X >= 10)
P(X >= 10) = 1 - P(X <= 9)
Now, using binomial probability table, we find that P(X <= 9) is 0.98266 at n = 25, p = 0.2 and x= 9
So, P(X >= 10) = 1 - 0.98266 = 0.0173.
Answer:
Is that it's not about the answers and the questions
X-int=-5 and the axis of symmetry is x=5.
Answer:
25 degrees
Step-by-step explanation:
angle CAD is a right angle, which is 90 degrees, and angle CAF is a straight line (180 degrees), which makes angle DAF a right angle. It is given that angle EAF is 65 degrees, therefore,
90 degrees - 65 degrees = 25 degrees
