Answer:
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
Distributed uniformly between 3mm and 13 mm.
This means that
Calculate the proportion of memory sticks that will be scrapped:
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
10x +y = xy +26
There are thee (3) sets of numbers that satisfy this.
.. (x, y) = (3, 2) . . . . the number is 32
.. (x, y) = (5, 6) . . . . the number is 56
.. (x, y) = (9, 8) . . . . the number is 98
If you solve the equation for y, you get
.. y = 10 -16/(x -1)
so x-1 is a 1-digit factor of 16: 2, 4, 8. These give rise to the solutions above.
Answer:
5.33333333333333
Step-by-step explanation:
32 divided by 6
6 fits 5 times into 32
6*5 = 30
2 is left, 2 is 1/3 of 6.
1/3 = 0.33333333333
So, its 5.333
X is 4 more than 5 times y
x=4+5y
if sum is increased by 3 (x+y+3), result is 31
x+y+3=31
minus 3 both sides
x+y=28
x=4+5y subsiutute
4+5y+y=28
4+6y=28
minus 4 both sides
6y=24
divide by 6
y=4
sub back
x=4+5y
x=4+5(4)
x=4+20
x=24
the numbers are 24 and 4
