Answer:

2 hours

Step-by-step explanation:

Using the work word problems, 1/3 + 1/6 = 2/6 + 1/6

3/6 = 2

setting 1/x, where 1 is a completed job, then x/1 = 2/1, therefore, the combined effort finishes the job in 2 hours. This is from the best of my knowledge. Purple Math is a great resource if extra help is needed.

What is the value of the expression 24 + 32? (2 points)
Maurinko [17]

Answer:

56

Step-by-step explanation:

Round: 24 is 20 and 34 is 30

20 + 30 = 50

now unrounded, it's easier.

24 + 32 = 56

because 4 + 2 = 6, we know to add on only a few more.

Indicate whether the following analysis involves a statistical test. If it does involve a statistical test, state the population
eimsori [14]

Answer:

Yes, The analysis involves a statistical test.

The hypothesis are H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L

Step-by-step explanation:

Consider the provided information.

Testing 500 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.

Yes, The above analysis involves a statistical test.

Where claim is right hand reacts faster than the left hand.

If right hand reacts faster that means the reaction time of right hand should be smaller than the reaction time of left hand.

Let \mu_R to be the average reaction time of their right hands for the right-handed participants and \mu_L to be the average reaction time of their left hands.

Therefore, the hypothesis are H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L
