Answer:
y = 5/2x -15
Step-by-step explanation:
5x - 2y = 30
-2y = -5x + 30
y = x -15
Step-by-step explanation:
cost price= 250000
depreciation= 10%
time or years= 2
depreciation price = cost price× depreciation%
2,50,000×10%
2,50,000×10/100
25,000
then 2 years depreciation = 1 year depreciation price ×number of years
25,000× 2
50,000
therefore depreciation price of machine after 2 years is 50,000
Answer:
(6x6x6x6)x(6x6)
Step-by-step explanation:
6 to the power of 4 times 6 to the power of 2
If a number a is to the power of b, that means a multiplied by itself, b times
eg 4 to the power of 3 means 4x4x4
hence, 6 to the power of 4 (or superscript four) means 6 itself, 4 times
so, 6x6x6x6 multiplied by 6x6
Answer:
range=u ± 3.09 sd
Step-by-step explanation:
Given:
mean, u= 26.8 mpg
standard deviation, sd=72 mpg
% contained in interval = 99.8%
the interval for 99.8% of the values of a normal distribution is given by
mean ± 3.09 standard deviation= u ± 3.09 sd
=26.8 ± 3.09(72)
=26.8 ± 222.48
= 249.28 , -195.68
range=u ± 3.09 sd = 249.28 , -195.68 !
