Answer:
Step-by-step explanation:
1/5 lawn = 20 min.
? = 1 min
0.05 lawn in 1 minute
rate of 0.05 mowed per minute.
Multiplication is basically repeating addition
So, on a numberline, start at 0 then add -6 three times (since you are multiplying it by three) and you should get -18
Answer: 119
Since the prior estimate of population proportion of defective handles (p) is unknown , so we take p= 0.5
Given : Margin of error : E=0.09
Critical value for 95% confidence interval :
Required sample size :-
Hence, the minimum sample size required = 119
i.e. 119 handles from the shipment should be inspected.
The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)
20x³ - 40x² + 80x
= 20x(x² - 2x + 4)
