Answer: $10000
Step-by-step explanation:
From the question,
Principal = $43000
Time = 5 years
Rate = Unknown
Simple Interest = $51,600 - $43000 = $8600
We need to calculate the rate of interest which will be:
Interest = PRT/100
8600 = (43000 × 5 × Rate) / 100
Cross multiply
8600 × 100 = 215000 × Rate
Rate = 860000 / 215000
Rate = 4%
Assuming Justine borrowed $50,000 instead, the yearly Interest will be:
= (50000 × 5 × 4%)
= 50000 × 5 × 0.04
= $10000
Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
Answer:
86
Step-by-step explanation:
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.
Answer:
-1.53 , 1.53
Step-by-step explanation:
It is basically asking you to find the percentiles. so for the bottom 6.3% you would type into your calculator 2nd, VARS, invNorm, area: .063, mean: 0, and Standard Deviation: 1 which gives you -1.53.
for the upper 6.3% you have to take 1-.063=.937 to get the upper percentile. now type into your calculator 2nd, VARS, invNorm, area: .937, mean: 0, and Standard Deviation: 1 which gives you 1.53.
I hope I helped :D
