Y = 2x + 5
(7,1)...x = 7 and y = 1
now we sub
1 = 2(7) + 5
1 = 14 + 5
1 = 19...incorrect....NO (7,1) is not a solution
***now if there was a typo and ur set of points are (1,7)
y = 2x + 5
7 = 2(1) + 5
7 = 2 + 5
7 = 7...correct....so (1,7) is a solution
Answer:
There is enough evidence at the 1% level of significance to suggest that the mean stopping distance of the truck is greater than 30
Step-by-step explanation:
We will conduct a hypothesis test for the mean. We will compare the mean stopping distance of the truck to the maximum distance of 30 and see if there is any significant difference.
We first need to find the mean and standard deviation of the stopping distance of the sample. See the first attached photo for the calculations of these values..
We get a sample mean of: 31.2333
and a sample standard deviation of: 0.2813
We will use these to conduct a hypothesis test. See the calculations for the test on the second attached photo
You take 67.8/100×15
10.17
then take 15-10.17 the answer will be the wrongs u got
=4.83
The real-life problem will be:- The total number of chocolates is 24 and there are 3 boxes what will be the number of chocolates filled in each box. The number of chocolates in each box will be 8.
