we are given
airthematic sequence
we can use nth term formula
n is number of terms
an is nth term
d is common difference
a1 is first term
We are given
a7=40
we can use it
a18 = 106
we can subtract both equations
now, we can find a1
we can plug d=6
12th term:
now, we can plug values
so, 12th term is 70...........Answer
Answer:
40.1%
Step-by-step explanation:
I am assuming that 192 is in 100%.
100% = 192
I then represent the value that we are looking for with .
x% = 77
By dividing both equations (100% = 192 and x% = 77) and remembering that both left hand sides of BOTH equations have the percentage unit (%).
Now, of course, we take the reciprocal, or inverse, of both sides:
x = 40.1%
Thus making the answer: 40.1% of 192 is 77.
Answer:
a) 0.954
b) 0.937
c) 0.891
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 6 percent
Standard Deviation, σ = 1.3 percent
We are given that the distribution of particular interest rate is a bell shaped distribution that is a normal distribution.
Formula:
a) P(At least 3.8 percent.)
Calculation the value from standard normal z table, we have,
b) P(At most 8 percent)
Calculating the value from the standard normal table we have,
c) P(Between 3.8 percent and 8 percent. )
