Answer:
25.4, 28.6
Step-by-step explanation:
Given parameters
sample size, n = 24
sample mean, X = 27
population standard deviation, s = 3
critical value, Zα/2, where α = 0.01
99% confidence Interval, CI, is given as follows
CI = X ± Zα/2 × (s/√n)
Zα/2 = Z0.01/2 = Z0.005 = 2.576
CI = 27 ± 2.576 × (3/√24)
= (25.42 ,28.57)
3.5 hours is 3 hours and 30 minutes.
1:15 is 1 hour and 15 minutes.
The question is asking at what time does she want to start and end up at 1 hour and 15 minutes? SO you add the time it takes for her to make the dessert with the time at which she ends.

Answer:
Step-by-step explanation:
After one year
A=p(1+r/n)^nt
=2000(1+0.03/12)^12*1
=2000(1+0.0025)^12
=2000(1.0025)^12
=2000(1.0304)
=$2060.8
After two-years
A=p(1+r/n)^nt
=2060.8(1+0.03/12)^12*2
=2060.8(1+0.0025)^24
=2060.8(1.0025)^24
=2060.8(1.0618)
=$2188.157
After three years
A=p(1+r/n)^nt
=2188.157(1+0.03/12)^12*3
=2188.157(1+0.0025)^36
=2188.157(1.0025)^36
=2188.157(1.0941)
=$2394.063
