Answer:
-5/3 = m
Step-by-step explanation:
Don't you mean (4, -1) and (1, 4)? If so, if we start with (1, 4) and move to (4, -1), then x (the "run") increases by 3 and y (the "rise") decreases by 5. Then the slope is m = rise / run = -5/3 = m
Answer:
p = 3
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
p-(3000*(1/1000))=0
Step by step solution :
Step 1 :
1
Simplify ————
1000
Equation at the end of step 1 :
1
p - (3000 • ————) = 0
1000
Step 2 :
Equation at the end of step 2 :
p - 3 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : p-3 = 0
Add 3 to both sides of the equation :
p = 3

Answer:
dependent-samples t test
Step-by-step explanation:
Here we want to test the effect of game Dance Dance Revolution (DDR) on heart rate.
The hypothesis is
where,
Where Xi = heart rate before playing the game Dance Dance Revolution (DDR)
Yi = heart rate after playing the game Dance Dance Revolution (DDR)
This test is paired t-test( dependent sample t test).
To measure the effect of experiment. (before - after condition)
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%
<h3>What is efficiency ?</h3>
Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Given that Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail.
Efficiency of hammer can be calculated as
efficiency = output obtained / input given
E=105/150
E=7/10
E=0.7
Converting into percentage
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%
