Step-by-step explanation:
By the Distributive Property,
2/5 * (15x - 10)
= (2/5)(15x) + (2/5)(-10)
= 6x - 4.
16,900,000 in scientific notation is 16.9 times 10^7.
When you move the decimal point to the 1, it goes 7 spaces to the left, so the exponent will be a positive 7.
Answer:
Step-by-step explanation:
Given is a sample of contents of a random sample of 10 containers as follows:
10.1 9.7, 10.5, 10.4, 9.8, 9.7, 9.4, 9.9, 10.7, and 9.7 liters.
To check whether the mean is 10.1 litres.
Set up hypothesis as
(two tailed test at 10% level of significance)
Sample mean =9.9
Sample std dev=0.420185
Std error =0.1329
n = 10
df = 9
Mean difference = 9.9-10.1 =-0.2
Test statistic t = -0.2/0.1329 =-1.505
p value= 0.1666
Since p value is >0.10 we accept null hypothesis
Conclusion:
the average content of containers of a particular lubricant is 10.1 liters can be taken as true at 90% level of confidence
