Ok, so here, we have the unit rate of the snail. Now, we need to set up a proportion.
60/1 = 120/x
Now, cross multiply.
60*x = 120*1
60x= 120
Now divide to solve for x.
60x/60 = 120/60
x = 120/60
x= 2
Now our final answer is 2.
Final answer:- The snail will take 2 minutes to crawl 120 feet
Answer:
The p-value of the test statistic from the standard normal table is 0.0017 which is less than the level of significance therefore, the null hypothesis would be rejected and it can be concluded that there is sufficient evidence to support the claim that less than 20% of the pumps are inaccurate.
Step-by-step explanation:
Here, 1304 gas pumps were not pumping accurately and 5689 pumps were accurate.
x = 1304, n = 1304 + 5689 = 6993
The level of significance = 0.01
The sample proportion of pump which is not pumping accurately can be calculated as,
The claim is that the industry representative less than 20% of the pumps are inaccurate.
The hypothesis can be constructed as:
H0: p = 0.20
H1: p < 0.20
The one-sample proportion Z test will be used.
The test statistic value can be obtained as:

Because a function must pass the vertical line test , a function can have at most one y -intercept .
The y -intercept is often referred to with just the y -value.
1.) Simply to 1/5 and 1/10
2.) put in decimal form 1/5= .2 and 1/10 = .1
3.) Add = .3
