Answer:
T=50.99
Step-by-step explanation:
Given:
I=3,875.78
P=1,900
R=4% I.e 4/100 , 0.04
T=?
I=PRT
3,875.79=($1,900)(0.04)t
3,875.79=76t
3,875.79/76= t
T=50.99
Answer and Step-by-step explanation:
a)
expected value for the difference in sample means=3.5-3.2=0.3
b)
standard deviation of the sampling distribution of the difference in sample means
=sqrt((0.5^2/40)+(0.8^2/40))
=0.1492
c)
z=(0.3-0)/0.1492
z=2.01
P(z>2.01)=0.0222
Answer:
5.75 - 1/2 times 8 divided by 2 + 6
Step-by-step explanation:
Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k =
=
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
