<h2>Answer:</h2>

          The probability of failure is:

                         0.5

<h2>Step-by-step explanation:</h2>

It is given that:

Janie flips a coin 70 times and records if it comes up heads.

Also, getting of a head is considered as a success.

This means that getting a tail will be a failure for the experiment.

As we know that for a unbiased coin the probability of getting a tail; and a head are equal.

Hence, the probability of head is: 1/2=0.5

and probability of tail is:   1/2=0.5

           Hence, the probability of a failure is: 0.5

Which figure is the image produced by applying the composition T 0,3 o R0,90 to figure R?
Lyrx [107]

We are given original image R.

It is being translated by (0,3) first and then rotated by a positive angle 90 degrees.

Translation by (0,3) represents (x,y) --> (x, y+3) rule.

Positive 90 degree rotation represents, counterclockwise rotation.

The rule for counterclockwise rotation is (x,y) --> (-y,x).

Therefore, final rule for would be

(x,y) --> ( -y,x+3 )

Let us take a coordinate of R on y-axis as (0,-4).

Now if we apply rule (x,y) --> ( -y,x+3 ) we get

(0,-4)  --> (-(-4), 0+3) = (4,3).

Let us check the figure with coordinate (4,3).

We can clearly see that Figure H has transformed coordinate (4,3).

<h3>Therefore, correct option is first option A. figure H.</h3>

a source of laser light sends rays ab and ac toward two opposite walls of a hall. the light rays strike the walls at points b an
marissa [1.9K]
Let  AM be the distance between point A and the right wall and AN be the distance between A and the left wall.
Δ AMB is an isosceles right triangle and  Δ ANC is half of an equilateral triangle.
Length of AM = 30 m. Length of AN = 1/2 · 80 = 40 m.
The distance between the walls is:
30 m + 40 m = 70 m.
