Answer:
Step-by-step explanation:
An insurance company has provided you with a sample of paid claims. The sample includes the following claims: 192, 113, 200, 287, and 225. What are the mean and the variance respectively of this sample rounded to the nearest whole number?
Answer:
27.00
Step-by-step explanation:
The original price was $60. What is the price of the item now? ... If the price has been reduced by 55 percent, this means we are paying for ... Let me know if you have any questions. ... Tutor. 4.9 (43). Semi-Retired Mechanical Engineer & Mathematician ... So, 45% of $60 = .45 x $60 = $27.00 (Price now).
Let x be the 1st odd number, and x+2 the second odd consecutive number:
(x)(x + 2) = 6[((x) + (x+2)] -1
x² + 2x = 6(2x + 2) - 1
x² + 2x = 12x +12 - 1
And x² - 10x - 11=0
Solve this quadratic expression:
x' = [+10 +√(10²- 4.(1)(-11)]/2 and x" = [+10 -√(10²- 4.(1)(-11)]/2
x' = [10 + √144]/2 and x" = [10 - √64]/2
x' = (10+12)/2 and x" = (10-12)/2
x = 11 and x = -1
We have 2 solutions that satisfy the problem:
1st for x = 11, the numbers at 11 and 13
2nd for x = - 1 , the numbers are -1 and +1
If you plug each one in the original equation :(x)(x + 2) = 6[((x) + (x+2)] -1
you will find that both generates an equlity
Answer:
x = -5/3
Step-by-step explanation:
-4 = 
-4×3 = 20 x
-12 = 20 x
1 x 4 = 4
4 x 5 = 20
20 x 6 = 120
120 x 7 = 840
So the answer is 840
