Answer:

  350 inches

Step-by-step explanation:

The 7 "ratio units" represent 490 inches, so each represent 490/7 = 70 inches. Then 5 "ratio units" will represent 5×70 inches = 350 inches.

  smaller perimeter : larger perimeter

  = 5 : 7

  = (350 inches) : (490 inches)

Answer: Probability that the entire batch will be accepted is 0.658.

Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.

Step-by-step explanation:

Since we have given that

Number of CDs = 507

Number of defective = 65

Since the entire batch will be accepted.

So, the probability of success is p = \dfrac{507-65}{507}=\dfrac{442}{507}=0.87

and the probability of failure is q = \dfrac{65}{507}=0.128

Number of CDs selected = 3

So, Probability that the entire batch will be accepted is given by

P(X=3)=^3C_3(0.87)^3\\\\P(X=3)=0.658

Hence, Probability that the entire batch will be accepted is 0.658.

Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.

Answer:

A. (x, y) -> (0.2x, 0.2y)

Step-by-step explanation:

I'll test this out with just point S if that's fine.

Point S's coordinates are (5, -5), as seen on the coordinate plane.

However,  Point S' has coordinates of (1, -1).

Divide 1 by 5 to get 1/5. You can also do -1/-5 to also get 1/5 (Remember, dividing two negatives gets you a positive.).

So you can conclude that the dilation has the x and y coordinates shrinking to 1/5 of the original. Both coordinates shrink at the same rate, so B and C are out. The figure is NOT getting bigger so D is also incorrect. This leaves A ((x, y) -> (0.2x, 0.2y)) as our answer.
