The answer is 1 hour 30 minutes. Think of the 50 and 20 mins as 5/6 and 2/6
Answer:
No
Step-by-step explanation:
If you plug in the coordinates (4,2) to y=x-2 it will give you 2=2 which is rite, but if you plug it in to y=3x+4 it will give you 2=16 which isn't rite.
Given:
Standard error = 4
Population standard deviation = 16
To find:
The value of n.
Solution:
The formula of standard error is:
Where, SE is standard error , is population standard deviation and n is the total number of elements.
Substituting in the above formula, we get
Taking square on both sides, we get
Therefore, the value of n is 16.
Answer:
Acceleration,
Step-by-step explanation:
Given that,
Initial speed = 4 m/s at 2 seconds
Final speed = 32 m/s at 9 seconds
We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,
So, the car's average acceleration is equal to .
25% of 52 is 13
that would make 65 dogs now
