Answer:
11.196%
Step-by-step explanation:
Given:
Buying cost of the investment or the principle amount = $1000
Time, n = 5 years
Selling cost of investment or amount received = $1700
Now,
the formula for compound interest is given as:
here, r is the rate of interest
on substituting the respective values, we get
or
(1 + r)⁵ = 1.7
or
1 + r = 1.11196
or
r = 0.11196
or
r = 0.11196 × 100% = 11.196%
Answer:
x=12
Step-by-step explanation:
twenty less = -20
from 8(times a number) and the number is unknown which means it would have variable next to the eight = 8x
therefore the equation would look like 8x-20 =76. then solve it like:
8x-20+20=76+20
8x = 96
8x/8=96/8
x= 12
We know that 0.8 is the same as 4/5. The reciprocal is basically a the denominator over the numerator. So in this case, the reciprocal of 0.8 would be 5/4
The probability is 0.246 or 24.6%.
We can use a binomial distribution for this:
Answer: 55%
1. 279 - 180 = 99
2. 99 divided by 180 = 0.55
3. 0.55 x 100 is 55.
55 is the percentage
