11.25cups. I got that by multiplying 2.5. by 4.5. If she wants to make 4.5 batches and 1 batch uses 2.5 cups, you have to multiply the cups of 1 batch by the number of batches she wants to make.
Answer:
The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard error of the mean . The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard distribution of the sample.
Step-by-step explanation:
The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
Answer:
4/5 + 3/4 = 
or 1.55
Step-by-step explanation:
This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.
The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:
The highest common factor of 4 and 5 = 4 * 5 = 20
This can now be used to solve 4/5 + 3/4 as follows:
4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 = or 1.55
Therefore, we have:
4/5 + 3/4 = or 1.55

8(8x64^2-1) factorises the lhs.
how it's equal to zero is beyond me
