Because Q and R are independent, you have

\mathbb P(Q\cap R)=\mathbb P(Q)\times\mathbb P(R)
0.08=0.4\times\mathbb P(R)
\implies \mathbb P(R)=0.2

The regular price of a watch is $32.25. During a sale, the watch was marked 16% off. What was the price of the watch during the
Serga [27]

Answer:

$ 27.09

Step-by-step explanation:

Given,

The regular price of the watch = $ 32.25,

The marked off percentage or discount percentage, in the sale = 16%,

So, the amount of marked off = 16% of regular price

= 16% of 32.25

= 0.16 × 32.25

= $ 5.16

Hence, the the price of the watch during the sale = Regular price - marked off

= $ 32.25 - $ 5.16

= $ 27.09

Last option is correct.

Point W has coordinates (4, -7). If it is translated left 4 units, what are the coordinates of its image?
denpristay [2]

Answer:

(0, - 7)

Step-by-step explanation:

A translation of 4 units left means subtracting 4 from the original x- coordinate, but the y-coordinate remains unchanged

W(4, - 7 ) → W'(4 - 4, - 7 ) → W'(0, - 7 )
