Answer:
5:21
Step-by-step explanation:
We know that currently (in the problem) it is 25 min before 4, or 3:35. When we add an hour to that (first part of the problem), we get 4:35. The way l like to continue from here is to take the second part (the 46 min) and just use part of it to round the hour off, and then add the other part to it.
From 4:35 to 5, we have 25 min
4.35 + 25 = 5
We subtract those 25 min from the 46 min, since we used them to round the hour off.
46 - 25 = 21
We have 21 min left, and now that the hour is rounded off, it's way easier to add minutes to it.
5 + .21 = 5.21.
So an hour and 46 min from 3:35 it will be 5:21. I hope this helps :)
Answer:
(0,2)
Step-by-step explanation:
u have to graph the equation on paper
Answer:
- Two sided t-test ( d )
- 0.245782 ( c )
- Since P-value is too large we cannot conclude that the students’ weight are different for these two schools. ( c )
- The test is inconclusive; thus we cannot claim that the average weights are different. ( b )
Step-by-step explanation:
1) Test performed is a Two sided test and this because we are trying to determine the mean difference between two groups irrespective of their direction
<u>2) Determine the P-value ( we will use a data-data analysis approach on excel data sheet while assuming Unequal variances )</u>
yes No
Mean 94.47059 89.76471
Variance 173.2647 95.19118
Observations 17 17
df 30
t Stat 1.184211
P(T<=t) one-tail 0.122814
t Critical one-tail 1.697261
P(T<=t) two-tail 0.245782
Hence The p-value = 0.245782
3) Since P-value is too large we cannot conclude that the students’ weight are different for these two schools.
4) The test is inconclusive; thus we cannot claim that the average weights are different.
2/1 ÷ 3/9
Whenever dividing fractions , the second fraction flips
2/1* 9/3
Multiply the numerators together
Then Multiply the denominators together
18/3 then divide by 3 for 18/3
18/3÷ 3/3
= 6
Answer is 6
