Answer: the second problem has a negative number and the first one has all positive numbers

Step-by-step explanation:

When you have a number in parentheses with a subtraction sign that number is negative

I don't think there is any difference, because 8-15=-7, and 8+(-15)=-7, because if you remove the parentheses, you will also get 8-15.

What is the measure of an interior angle of a regular three-sided polygon?
noname [10]
The formula to find the measure of an interior angle is (n - 2) * 180/n, where n represents the number of sides in the polygon. In this problem, n would represent 3. 

Let's plug in the value for n
(3 - 2) * 180/3
Let's simplify that. 
=60

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!

The weights of certain machine components are normally distributed with a mean of 8.04 g and a standard deviation of 0.08 g. Fin
NISA [10]

Answer:

The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Step-by-step explanation:

We are given that

Mean, \mu=8.04 g

Standard deviation, \sigma=0.08g

We have to find the two weights that separate the top 3% and the bottom 3%.

Let x be the weight of  machine components

P(Xx_2)=0.03

P(X

=0.03

From z- table we get

P(Z1.88)=0.03

Therefore, we get

\frac{x_1-8.04}{0.08}=-1.88

x_1-8.04=-1.88\times 0.08

x_1=-1.88\times 0.08+8.04

x_1=7.8896

\frac{x_2-8.04}{0.08}=1.88

x_2=1.88\times 0.08+8.04

x_2=8.1904

Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.
