How do you convert feet to inches?
Well I will tell you.
12 inches = 1 foot
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
Answer:
X = 108.
Step-by-step explanation:
Heights are equal, So equation will be,

So, solving the eq.
Subtract 4 from both sides ,

Divide 3 to both sides,

Squaring both sides,

Add 8 to both sides,

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

Applying the given data:

For the given material, the lower confidence bound for true average Brinell hardness is 61.57.
Answer:
A = 48 inches ^2
Step-by-step explanation:
The area of a rectangle is found by
A = lw
A = 8* 6
A = 48 inches ^2
