Artyom0805 [142]

Answer:

{2,4,6}

Step-by-step explanation:

the domain is the interval or set of valid x (input) values.

the range is the interval or set of valid y (result) values.

just use the x values in the functional definition and collect the results. these are the range.

x = -1

y = 2×-1 + 4 = 2

x = 0

y = 2×0 + 4 = 4

x = 1

y = 2×1 + 4 = 6

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when so
Ierofanga [76]

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

4 + 3 \sqrt{x - 8}  = 34

So, solving the eq.

Subtract 4 from both sides ,

3 \sqrt{x - 8}  = 30

Divide 3 to both sides,

\sqrt{x - 8}  = 10

Squaring both sides,

x - 8 = 100

Add 8 to both sides,

x = 108

A Brinell hardness test involves measuring the diameter of the indentation made when a hardened steel ball is pressed into mater
Hatshy [7]

Answer:

61.57

Step-by-step explanation:

Sample size (n) = 32

Sample mean hardness (X) = 64.3

Sample standard deviation (s) = 6.0

Z-score for a 99% confidence interval (Z) = 2.576

The lower confidence bound (L) for a confidence interval is determined by the following expression

L= X - Z*\frac{s}{\sqrt{n} }

Applying the given data:

L=64.3 - 2.576*\frac{6.0}{\sqrt{32}}\\L=61.57

For the given material, the lower confidence bound for true average Brinell hardness is 61.57.
