Step-by-step explanation:
1)
Let us consider that Cecilia's has a total of 'x' CDs
and let 'y' represent the number of Jazz CDs.
Now we are given information that:
1/5 of her Jazz CDs represents 1/10 of all her CDs.
i.e.
i.e. the Jazz CDs are half of the total CDs.
Hence, the number of Non-Jazz CDs(z)
=
Hence, the ratio of Jazz to Non-Jazz CDs
Hence, the required Ratio is 1:1.
2)
How would you change to a number times 25?
We will find the number by dividing the quantity by 25 to find the required number.
i.e.
Hence the required number is:
Step-by-step explanation:
hihi, so given a statistic, a sample standard deviation, and the sample size, we can create a 99% confidence interval for this distribution. Given the equations for confidence interval and Margin of Error, all we have to calculate initially is t* (invT(.995, 85-1)) and Standard error (34/sqrt(85)). Once we have these numbers, it's as easy as plugging in and doing some simple calculations to reaching our upper and lower fences of our interval. (136.28, 155.72). Any value below the lower fence or any value above the upper fence is not in our interval
Answer:
Yes. 3x²y and -5x²y are like terms because the variables x and y have the same exponents.
