Answer:
350 customers
Step-by-step explanation:
Since this is a ratio question and we only have variable that we need to solve (total people that entered last week), Then we can use the Rule of Three to solve this problem. We do this by multiplying the diagonal values of the following model and dividing by the third value in order to find the variable, like so...
18% of customers <====> 63 customers
100% of customers <====> x customers
(100 * 63) / 18 = x
6,300 / 18 = x
350 = x
Finally, we can see that a total of 350 customers entered the store last week.
Answer:
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to the normal distribution if:
np > 5, n(1-p) > 5
70% of the drivers traveling on a major interstate highway exceed the speed limit.
So p = 0.7.
Would a random sample of 50 cars have been large enough and why?
With n = 50
np = 50*0.7 = 35 > 5
n(1-p) = 50*0.3 = 15 > 5
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.
Answer:
4. James' hand
5. Salvador's plane traveled the furthest and Jennifer's plane traveled the shortest.
Step-by-step explanation:
4. James' hand is bigger because 0.17>0.165. You can add as many zeros to the end of each of them as you would like. You can think of this word problem as 0.170 versus 0.165. Or, if you needed to, you could pretend like they're whole numbers, and it would be 170 versus 165. Either way, 0.170 is going to be bigger than 0.165.
5. Salvador's plane traveled the furthest. Jennifer's plane traveled the shortest distance. All three numbers have a 3.3 in them. Now, it's a matter of who has the highest number in the blank after the 3.3: 3.3_. Because Jennifer's plane had a 0 in the blank, she traveled the shortest distance. 5 is bigger than 4.5, so Salvador's plane (the 3.35 one) traveled furthest.
