Answer:

  • C)  (x, y) ⇒ (-x, y)
  • D)  (x, y) ⇒ (x, y+4)

Step-by-step explanation:

ΔDEF is a reflection and translation of ΔABC.

You know it is a reflection because the corresponding vertices have opposite orientations: CCW vs. CW. You know it is a horizontal reflection because the line EF corresponding to vertical line BC is still vertical.

You know a vertical translation is involved because corresponding vertices are all offset vertically from each other by the same amount (4 units).

A group of 40 bowlers showed that their average score was 192. Assume the population standard deviation is 8. Find the 95% confi
kodGreya [7K]

Answer:

CI=189.5,194.5

Step-by-step explanation:

From the question we are told that:

Sample size n=40

Mean \=x =192

Standard deviation\sigma=8

Significance Level \alpha=0.05

From table

Critical Value of Z=1.96

Generally the equation for momentum is mathematically given by

 CI =\=x \pm z_(a/2) \frac{\sigma}{\sqrt{n}}

 CI =192 \pm 1.96 \frac{8}{\sqrt{40}}

 CI=192 \pm 2.479

 CI=189.5,194.5
