So first make sure thtat the bottom number is the same so
7 and 3 and 2
multily them together and get 42
so multtiply 3/7 by 6/6 or 1=18/42
multiply 2/3 by 14/14=28/42
multply 1/2 by 21/21=21/42
18/42+28/42+21/42=(18+28+21)/42=67/42
simplify
1 and 25/42 miles
The hypothesis testing for this problem is:
a. The hypothesis for this problem are:
Null: H0: μ=6
Alternative: Ha: μ≠6
b. Test
T-statistics = (6.08 - 6) / 0.44* √(121) = 2
c. P value = 0.047759
Since our p-value is smaller than the significant level of 0.05, we can say that we reject the null hypothesis.
Conclusion: there is enough evidence to say lathe is not in perfect adjustment.
Dilation:
The dilation factor is the length of image/preimage = 1.5
Thus
Q'R'/QR=1.5
Q'R'=1.5QR = 1.5 (5 cm) = 7.5 cm
