Answer:

The probability that Aaron goes to the gym on exactly one of the two days is 0.74

Step-by-step explanation:

Let P(Aaron goes to the gym on exactly one of the two days) be the probability that Aaron goes to the gym on exactly one of the two days.

Then

P(Aaron goes to the gym on exactly one of the two days) =

P(Aaron goes to the gym on Saturday and doesn't go on Sunday) +

P(Aaron doesn't go to the gym on Saturday and goes on Sunday)

If Aaron goes to the gym on Saturday the probability that he goes on Sunday is 0.3. Then If Aaron goes to the gym on Saturday the probability that he does not go on Sunday is 1-0.3 =0.7

Since the probability that Aaron goes to the gym on Saturday is 0.8,

P(Aaron goes to the gym on Saturday and doesn't go on Sunday) =

P(the probability that Aaron goes to the gym on Saturday)×P(If Aaron goes to the gym on Saturday the probability that he does not go on Sunday)=

0.8×0.7=0.56

The probability that Aaron doesn't go to the gym on Saturday is 1-0.8=0.2

And if Aaron does not go to the gym on Saturday the probability he goes on Sunday is 0.9.

Thus, P(Aaron doesn't go to the gym on Saturday and goes on Sunday) = P(The probability that Aaron doesn't go to the gym on Saturday)×P(if Aaron does not go to the gym on Saturday the probability he goes on Sunday)

=0.2×0.9=0.18

Then

P(Aaron goes to the gym on exactly one of the two days) =0.56 + 0.18 =0.74

Triangle LMN with vertices L(1,5), M(3,8), and N(8,1); 90° clockwise

zaharov [31]

Answer

L' (5, -1)

M' (8, -3)

N' (1, -8)

The sketch of this rotated triangle is presented below

Explanation

Rotating a given coordinate A(x, y) 90° about the origin in the clockwise direction gives a new coordinate A'(y, -x)

So, for each of these,

L (1, 5) → L' (5, -1)

M (3, 8) → M' (8, -3)

N (8, 1) → N' (1, -8)

So, to draw this image, we will mark this new rotated points on the graph, then connect the points to form triangle L'M'N'.

The sketch of this rotated triangle is presented above under 'Answer'

Hope this Helps!!!

A, B, and C are collinear, and B is between A and C. The ratio of AB is 1:1. If A is at (1,-9) and B is at (2,0), what are the c

USPshnik [31]

Answer:

(3,9)

Step-by-step explanation:

So I drew a right triangle with the line segment A(1,-9) to C $(a,b)$ as the hypotenuse. This line segment does contain point B(2,0). This is shown in the picture.
