Answer:
(x, y, z) = (1/3, 2/3, 1)
Step-by-step explanation:
We can use the first equation to write an expression for x that can be substituted into the other equations.
x = 1 -y
2(1 -y) -y +z = 1 ⇒ -3y +z = -1
(1 -y) +2y +z = 8/3 ⇒ y +z = 5/3
Subtracting the first of these equations from the second gives ...
(y +z) -(-3y +z) = (5/3) -(-1)
4y = 8/3
y = 2/3
z = 5/3 -y = 1
x = 1 -y = 1/3
The solution is (x, y, z) = (1/3, 2/3, 1).
Find a common denominator
7/10 + 5/10
= 12/10
mixed number is 1 1/5
Answer:
12/14
Step-by-step explanation:
it says 12 do the high jump and 14 do the long jump so it will be 12/4
15.9 / 100 = c / 25,250....15.9 c sections to 100 women = c to 25,250 women
cross multiply
(100)(c) = (15.9)(25,250)
100c = 401475
c = 401475/100
c = 4014.75 <===
In order to obtain a standard deviation of 0, all members of the data set should be equal.
This means that each of the 100 members in the data set is equal to 50 (the mean value).
Answer:
The smallest observation in the set is 50.
