For a specific type of machine part being produced, the diameter is normally distributed, with a mean of 15.000 cm and a standar

d deviation of 0.030 cm. Machine parts with a diameter more than 2 standard deviations away from the mean are rejected. If 15,000 machine parts are manufactured, how many of these will be rejected?
a. 560
b. 680
c. 750
d. 970

This problem involves Statistics. When you are talking about the number of deviations, you directly refer to what we called the Empirical Rule.

The empirical rule states that 95% of the values will lie within 2 standard deviations of the mean. So 100% - 95% = 5% of the parts will be rejected. So
(0.05)*(15,000) = 750

Therefore, 750 machine parts are rejected. Hope this helps! :D

Consider the limaçon with equation r = 3 4cos(θ). how does the quotient of a and b relate to the existence of an inner loop?
Delicious77 [7]

If the equation is r = 3 +4cos(θ) then because b/a>1 the curve is a limacon with an inner loop.

Given limacon with equation r=3+4cos(θ) and we have to answer how the quotient of a and b relate to the existence of an inner loop.

Equation is like a relationship between two or more variables expressed in equal to form and it is solved to find the value of variables.

formula of polar graph is similar to r= a+ b cos (θ).

Case 1. If a<b or b/a>1

then the curve is a limacon with inner loop.

Case 2. If a>b or b/a<1

Then the limacon does not have an inner loop.

Here given that r=3+4cos (θ)

It is observed that , a<b or b/a>1

Therefore the curve is limacon with an inner loop.

Hence because b/a>1 the curve is a limacon with an inner loop.

List the sides of each triangle from shortest to greatest
Lelechka [254]
In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.


a.70^o\ \textgreater \ 60^o\ \textgreater \ 50^o so |RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|, 

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ


b. The sum of the measures of the interior angles of any triangle is 180°, 

so 

m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o

thus, m(C) is the largest angle. This means the largest side is the side AB.



Answers:

a) RQ
b)AB
