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)
1/2 times 8 equals 4.
You multiply by 8 because the denominator is 8 so you have to have that recipe 8 times to get a whole.
Answer:
1,188
Step-by-step explanation:
- multiply the two numbers
- divide your answer by two
- then you have your answer
Answer:
y = - x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 2 ← is in slope- intercept form
with slope m = -
• Parallel lines have equal slopes , then
y = - x + c ← is the partial equation
to find c substitute (4, - 2 ) into the partial equation
- 2 = - 7 + c ⇒ c = - 2 + 7 = 5
y = - x + 5 ← equation of line
