Answer:
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
Rewrite 4, 8 and 32 as following:
4=2²
8=2³
32=2⁵
Rewrite the expression:
Keeping on mind the exponents properties, you have:
As the bases are equal, then:
Answer:

??????????????????
Answer:
1.5% of 4000 or 60
Step-by-step explanation:
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.
