√8 is between 2 and 3, because 2²=4<8, but 3²=9>8. Also, our value is closer to 3 than to 2, so it is more than 2.5 and we have C and D options left.
Among these two numbers we find the one which is closer to √8.
C. 27=√729 ⇒ 2.7=√7.29
D. 28=√784 ⇒ <u>2.8=√7.84</u>
Hence our answer is D) 2.8
Answer:
1/4 or 25%
Step-by-step explanation:
Let's see, we want to know probability of an event in which we roll two even numbers.
"We know that probability is defined as number of desired outcomes divided by all possible outcomes"
e - even number
o - odd number
our desired outcome: (e, e) total of 1
all possible outcomes: (e, e), (e, o), (o, e), (o,o) total of 4
that gives us 1/4
The multiplier for continuous compounding is e^(rt). You want
700,000 = P·e^(0.05·25) ≈ 3.490343P
Then
700,000/3.490343 = P
You should invest $200,553 initially.
Answer:
B
Step-by-step explanation:
n - 4 = 4.5 - 4 = 0.5
8(n - 4) = 8 *(0.5 ) = 4
6 *n = 6 * 4.5 = 27
8(n - 4) + 6n
8(0.5) + 6*4.5
4 + 27
31
