Given that w =(x + y)/z
Alchen [17]

The lower and upper bounds of w is 3 and 4.16

What is Upper bound and Lower bound?

An element of K that is bigger than or equal to every element of S is referred to as an upper bound or majorant of S in mathematics, specifically in order theory. In contrast, a lower bound or minorant of S is defined as an element of K that is smaller than or equal to every element of S. A set that has an upper (or lower) bound is said to be majorized[1] (or minorized, respectively) from above (or below) by that constraint.

Given that,

w =(x + y)/z

x = 2.5 ± 0.5,

y = 1.5 ± 0.5

and, z = 1.1 ± 0.1

Substituting the values in the equation to find upper bound

x = 3.0

y = 2.0

z = 1.2

Then,

w = (3 + 2)/1.2

w = 5/1.2

w = 4.16

Substituting the values in the equation to find lower bound

x = 2.0

y = 1.0

z = 1.0

Then,

w = (2 + 1)/1

w = 3/1

w = 3

Hence, The upper bound of w is 4.16

The lower bound of w is 3

In january of one winter, 3/10 of a wood pile was used in a wood stove. In February, 2/5 of the wood pile was used. What part of
arsen [322]
2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10

At the end of February, 7/10 of the wood was used

-Find the y-intercept of the line with the equation 2x+y=5.
AlekseyPX

Answer:

E.  5

Step-by-step explanation:

Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

2x + y = 5

y = -2x+5

M, the slope, is -2

<u>5, b, is the y-intercept</u>

See attached graph.
