What are ALL the true statements.
ale4655 [162]

Answer:

C, E, F

Step-by-step explanation:

A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.

B is a true statement.

C is true because when angles undergo dilations, their "size" does not change.

D is false because dilations do not increase the measures of angles.

E is false because a triangle that underwent a dilation becomes similar, not congruent.

F is true because of E's reasoning.

An assembly consists of two mechanical components. Suppose that the probabilities that the first and second components meet spec
SVETLANKA909090 [29]

Answer:

The probability mass function is given by

P(X = 0) = 0.003, P(X = 1) = 0.164, P(X = 2) = 0.833

Step-by-step explanation:

Given to us are two mechanical components.

The probability of the first component meeting the given specifications are 0.98.

The probability that the second component meets the given specifications  = 0.85.

In the information given the components are said to be independent.

The probability mass function will be calculated in the following way

i.) P(X=0) which is the probability that neither of the components meet the specifications.

ii) P(X=1) which is the probability when either of the components will meet the specifications and the other will not.

iii) P(X=2) which is the probability that both components meet the specification.

Therefore P(X = 0) = ( 1 - 0.98) × ( 1 - 0.85)  = 0.02 × 0.15  = 0.003

and,          P(X = 1)  =    (0.98 × ( 1 - 0.85)) + (( 1 - 0.98) × 0.85)

                              =   (0.98 × 0.15) + (0.02 × 0.85)

                              =   0.147 + 0.017

                              = 0.164

and finally, P(X=2) = (0.98 × 0.85)

                              = 0.833

A cylindrical can is to have volume 1500 cubic centimeters. determine the radius and the height which will minimize the amount o
Degger [83]
Assuming R and H:
So volume is pir^2 * H = 1500 and H = 1500/(pir^2)  while surface area is A= 2pir*H + 2pir^2 
A = 2pir(r+h)= 2piR^2 + 2pir*1500/(pir^2)= 2piR^2 + 3000/r
For A to take minimum, get the derivative 4pir - 3000/R^2 and let it be 0 
4pir^3 - 3000 = 0 
r = cbrt(3000/(4pi)) ≈ 6.20
h = 1500/(pi(6.20)^2) ≈ 12.42
