Answer:
The quotient is .
Step-by-step explanation:
We do this as the simple division that we do with the integers.Find a quotient that is same as the first on multiplying with the divisor term of the dividend.
Divisor = x+1.
Dividend = 2x²-3x-5
We found that on multiplying 2x with x+1 we will get 2x²+2x and then subtracting it from dividend we will get -5x-5. We found that only multiplying the divisor with -5 we will get -5x-5 and on subtracting it from the dividend the the remainder will be 0. Hence the quotient is 2x-5.
Answer:
Step-by-step explanation:
Two cases arise to obtain the median.
Case (1): Sample size (n) is odd
First, arrange the data in ascending order. Then, the median is the middle value and lies at the position.
Case (2): Sample size (n) is even
First, arrange the data in ascending order. Then, the median is the mean of the two data values that lie on and positions.
Formula for mean is, where is the sum of all observations and n is the total number of observations.
(1)
Use the below process to create a set of 5 positive numbers (repeats allowed) that have median 7 and mean 10.
1.Select the 5 ordered numbers with middle value 7.
2.Adjust the remaining 4 numbers other than 7 to get mean 10 without changing the order of the numbers.
Based on the process to select the 5 ordered numbers with middle value 7 and change the other ordered numbers to get the mean value 10.
(2)
The product of the mean and the total number of observations is obtained. Then, the sum of four observations is subtracted from the product.
Here, the first four numbers are (5, 6, 7, 8).
The last number by using mean 10 is,
The last number is 24.
