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:frfr it made hard
Step-by-step explanation:
You have the right one selected.
The answer is 2:1
To find this take each side of ABC and its corresponding side on DEF, then simplify. You can treat ratios just like fractions, so simplify them in the same way.
20:10 becomes 2:1
12:6 becomes 2:1
16:8 becomes 2:1
Answer:
Let x = 1
LHS: -4(1)+(-2)=-4+(-2)=-6
RHS:3(1)+(-5)=3+(-5)=-2
Therefore -4x+(-2) is not equal to 3x+(-5)
