Answer:
C
Step-by-step explanation:
In this question, we are asked to select which of the options best answer the question.
We proceed as follows;
Using the information given,
Each of the 110 students in a statistics class selects a random sample of 35 Quiz scores
from a population of 5000 scores. They are not given the population mean and standard deviation.
Now, using these data, each student then construct a 90% confidence interval for µ which is the average Quiz score in the population of 5000 students.
By definition, the population mean values will definitely be within the limits of this
confidence interval.
Thus, the correct answer is, Option (c)
Answer:
the square root of 10000 is 100
square of 56 is 3136
Step-by-step explanation:
Answer:
x can be 10 or -10
Step-by-step explanation:
Let the first and smaller number be x. Since the second number is 5 times the first, the second number is 5x. We also know both of these numbers must add to 50; thus, we can create the following equation.

Combine like terms

Divide both sides by 6

This is the value of the first number. The number you're looking for isn't specified in the question description, so I'll just provide the value of the second number. The second number has to be 5 times the first.
Thus, we just multiply 5 to x.

That's the value of the second number.
If you were to make both x's equivalent, you'd have to multiply the first equation by 2 to get rid of the coefficient, 1/2. However, you'd have to multiply 2 onto -8 as well, therefore the equation would turn into x - 16 = 18. That is not equivalent to x - 8 = 18.
