1. 1:38 AM to 4:38 AM is 3 hours, 4:38 AM to 4:50 AM is 12 mins. This means that total time elapsed is 3 hours and 12 mins. Rounding to nearest hour gives 3 hours.

2. I assume you mean 11:49 AM. 11:49 AM to 6:49 PM is 7 hours. 6:49 PM to 7:12 PM is 23 mins. Total time is 7 hours 23 mins, or 7 hours to the nearest hour.

3. 2:25 PM to 3:25 PM is 1 hour, 3:25 PM to 3:35 PM is 10 mins. Total time is 1 hour 10 mins or 1 hour to the nearest hour.

4. 8:25 AM to 10:25 AM is 2 hours. 10:25 AM to 10:52 AM is 27 mins. Total time is 2 hours 27 mins or 2 hours to the nearest hour.

The trick is to count the number of hours first, then count the number of minutes remaining.

Which of the following is NOT true about​ P-values in hypothesis​ testing? Choose the correct answer below. A. If the P is​ high
pashok25 [27]

Answer:

Step-by-step explanation:

In statistical hypothesis testing we use p values.  For any test we select significance level alpha as 5% or 1% or 10%

Whenever p < alpha we reject our null hypothesis.  Otherwise we accept our null hypothesis.

Hence p should be high to accept null hypothesis

Option A is incorrect

B is correct

C is wrong as p is the probability

D False

Option B is right.

yuradex [85]

Answer:

  1. b
  2. f
  3. e
  4. c
  5. h
  6. d
  7. g
  8. a

Step-by-step explanation:

< or > will give you an open dot which means it is not filled in.

≤ or ≥ will give you a closed dot which means it is filled in.

So for example number one:

x > 0 translated is x is greater than zero.

So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.

The federal government requires a car manufacturer to have a minimum miles per gallon (mpg) average over the models it makes. Su
valentinak56 [21]

Answer:

25 mpg

Step-by-step explanation:

We have a set of values 19, 21, 22, 28  and 18  

The average (which is the mean of the set of values )  is :

19 + 21 + 22 + 28 + 18 = 21.6 mpg   out of the government requirement

So we need a value such as the mean become at least 25 mpg

We have to solve the equation:

(19+21+22+28+ x)/ 5  = 25

 (90 + x ) /5  = 25       ⇒   90 + x = 125   ⇒   x = 35 mpg

If we get the mean of the set of values including 35 we have:

(19 +21+ 22+ 28 + 35 ) / 5   =  25 mpg  government requirement
