Answer:
840 has 6 odd factors
Step-by-step explanation:
Answer:
10/24 and 15/36, more answers possible
Step-by-step explanation:
if you multiply both the numerator and denominator by the same number, it will always be equivalent to 5/12, as you can simplify it back to that fraction.
5/12, multiply both by two, and you have 10/24
5/12, multiply both by three, and you have 15/36
Answer:
50
Step-by-step explanation:
68+62=130 then subract 180-130 and have 50 so x=50
Answer:
Step-by-step explanation:
The confidence interval gives a range of values that could contain the population mean.
Confidence interval is written as
Sample mean ± margin of error
Confidence interval does not express probability.
Given that the sample mean home price for city A is $189500 and the sample mean home price for city B is $185000, the difference in the sample mean home prices for both cities is
189500 - 185000 = $4500
Since the margin of error for 95% confidence interval for the difference in average home price between the two cities (A-B) to be $3400, then
The upper limit of the confidence interval is
4500 + 3400 = $7900
The lower limit of the confidence interval is
4500 - 3400 = $1100
Therefore, the correct conclusion is
Beatrice can be 95% confident that the average home price is between $1100 and $7900 more in city A than in city B.
For the matrix given , the element a₂₃ is the number at 2nd row and 3 column ,which is 6 , Option B is the correct answer.
<h3>What is a Matrix ?</h3>
It is a table or a rectangular array of numbers or expressions arranged in rows and columns ,
For a Matrix of m x n , m is the no. of rows and n is the no. of column
For the matrix given the element a₂₃ is the number at 2nd row and 3 column ,
which is 6 ,
Therefore Option B is the correct answer.
