I know for sure that the bottom two choices are congruent
Answer:
x=ab-c
Step-by-step explanation:
a=x/b+c
You multiply both sides by b to get rid of the fraction.
a(b) =x+c
Subtract c so you are only left with x
a(b)-c=x
There's your answer!
x=ab-c
Answer:
a level of significance of 0.01 = 1%
Step-by-step explanation:
given
Z = 0.0001
mean μ=0.21 g/mi
variate x= 0.21 + 0.03
standard deviation σ= 0.05 g/mi.
N = sample population 20 cars
z = (x −μ
)/[σ
/√N ]
Z =
Z = 0.03/ (0.05/√20) = 0.03/0.0111
Z = 2.63 +- 0.0001
Z= 2.6301 or 2.6299
checking the level of significance table from a statistical book gives
a level of significance of 0.01 = 1%
therefore the null hypothesis is accepted.
