Answer:
(2, 5)
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
Substitute y = x + 3 into (2)
- 2x + x + 3 = 1
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5)
A normal distribution is symmetrical about the mean. Therefore half of all young men are shorter than 68 inches.
Answer: D
80 000 > 0,00004

The ratio of sweets between the people would be
Sushil:Alex:Peter or 3:2:5
In this case, Sushil has 24 sweets meaning that 3 was multiplied by 8 in order to get 24. This means that we have to multiply all the numbers by 8 and and them up.
24+(2x8)+(5x8)
=24+16+40
=80 sweets
