17 I think so ye how is a triangle a triangle is it’s half a square?
Answer:
I think its 2 hours 30 minutes
Step-by-step explanation:
Answer:
The correct answer is:
the amount of difference expected just by chance (b)
Step-by-step explanation:
Standard error in hypothesis testing is a measure of how accurately a sample distribution represents a distribution by using standard deviation. For example in a population, the sample mean deviates from the actual mean, the mean deviation is the standard error of the mean, showing the amount of difference between the sample mean and the actual mean, occurring just by chance. Mathematically standard error is represented as:
standard error = (mean deviation) ÷ √(sample size).
standard error is inversely proportional to sample size. The larger the sample size, the smaller the standard error, and vice versa.
If triangle ABC is equilateral,solve for X56x-308
1000 is our constant because the truck was only used one day. We also know they charge a certain amount per hour, but we do not know how much. In this case they charged that amount 9 times because the truck was used for 9 hours. The total of the constant plus the 9hour fee is 2700 dollars:
1000(1) + 9x = 2700
The reason we multiply 1000 by 1, is because we only used the truck for one day.
Solve for x
9x = 2700 - 1000 = 1700
X = 1700/9 = 188.88
The hourly fee is $188.88
The question is asking for an equation for hours of use though, so the answer is
1000(1) + 9(188.88) = C
C represents cost or charge.
