We are given with
x1 = 20 min
s1 = 2 min
x2 = 30 min
s2 = 4 min
p = 0.9
Condition (x > 25)
We need to get the t-value between the two means and comparing it wit the t-value for the time of 25 minutes given that there is a 90% probability that the weather will be good. Simply use the t-test formula and use the t-test table to get the probability.
Answer:
the same volume 363 because the cone and cylinder have the same radius and heith
Answer:
x^9 + 90 x^8 + 3600 x^7 + 84000 x^6 + 1260000 x^5 + 12600000 x^4 + 84000000 x^3 + 360000000 x^2 + 900000000 x + 1000000000
Answer:
Interest rate: 9%
Step-by-step explanation:
Using the simple interest formula: A=P(1+rt)
A=Final amount
P=Principal amount
r=rate
t=time (years)
We just need to put in the information we have from the question and solve for r.
7,620=6000(1+r3)
7,620/6000=1+r3
1.27=1+r3
0.27=r3
r=0.09
r=9%
Answer:
probably -3, -1 bc it is local to origin and the minimum in that situation. I just got into this topic myself so I'm not exactly sure
