#1 This isn't mathematics its Science
#2 I would personally say false because we can repeat a song there fore creating the same movement - vibration. Heat is also something that could be the same again. Like setting the thermostat in a home, apartment, or work place
#3 Don't hold me to #2 because I can see both sides being argued #1 is definitely right lol!
Here is the solution based on the given problem above.
Given: 25miles/hour = speed of the cyclist
? = speed in feet/second
1 mile = 5280 feet
1 hour = 3,600 seconds
In order to get the result, we need to get first how many feet is 25 miles.
so, 25 miles is equivalent to 132,000 feet.
and 1 hour = 3,600 seconds
So, it is 132,000 feet/3,600 seconds. Let us simplify this.
So the answer would be 36.67ft/second.
I hope this is the answer that you are looking for.
Answer:
+3
Step-by-step explanation:
if your subtracting a negitive it means your adding and its now a positive
Answer:
H0 : μ = 60000
H1 : μ ≠ 60000
Test statistic = 3.464
Step-by-step explanation:
Given :
Sample mean salary, xbar = 80000
Sample standard deviation, s = 10000
Population mean salary , μ = 60000
Sample size, n = 3
Hypothesis :
H0 : μ = 60000
H1 : μ ≠ 60000
The test statistic :
T = (xbar - μ) ÷ (s/√(n))
T = (80000 - 60000) ÷ (10000/√(3))
T = 20000 / 5773.5026
T = 3.464
The Decison region :
If Tstatistic >Tcritical
Tcritical at 10%, df = 2 ; two - tailed = 2.9199
Tstatistic > Tcritical ; He
