Answer:

-2 and 4

Step-by-step explanation:

If you put either -2 or 4 into the equation you'll get zero.

Another way of determining it is finding value of x-coordinate where curve intersects the x-axis. In the graph, curve passes through x-axis at x = -2 and x = 4.

$1200+ $1400 = 2600

Answer:
1200 : 1400 = 6 : 7

The ratio is not in lowest terms so we found an equivalent ratio by simplifying.
Solution:

We can simplify the ratio 1200 : 1400 by dividing both terms by the greatest common factor (GCF).

The GCF of 1200 and 1400 is 200.

Divide both terms by 200.
1200 ÷ 200 = 6
1400 ÷ 200 = 7

Therefore:
1200 : 1400 = 6 : 7

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.
