<h2>Answer:</h2><h2>The probability that Roy gives randomly an SUV = 15 / 47</h2>

Step-by-step explanation:

The total number of used cars owned by Roy = 47

[12 trucks + 20 cars + 15 SUV = 47 cars]

The total number in sample space, n (S) = 47

The probability that Roy is giving away and SUV = ?

Let A be the event that Roy is giving an SUV

Total no of SUV's , n (A) = 15

The probability of giving an SUV, P (A) = n (A) / n (S)

                      P (A)  = 15 / 47

Carol's starting pay for her summer job is $10.25 per hour. Carol earns exactly 3 raises this summer.
zlopas [31]
We know that
1) <span>Carol's starting pay for her summer job is $10.25 per hour
</span><span>Carol earn per hour=$10.25 per hour
</span><span>
2) </span><span>For the first rise, she receives a 50 cent-per-hour raise
10.25+0.50=10.75
</span>Carol earn per hour=$10.75 per hour

3) <span>For the second rise, she receives a 10% raise per hour
10.75*1.10=11.825
</span>Carol earn per hour=$11.825 per hour

4) <span>For the third rise, she receives another 50 cent-per-hour raise
11.825+0.50=12.325
</span>Carol earn per hour=$12.325 per hour

5) At the start of next summer. She will be given a 5% raise per hour based on her pay at the end of this summer. <span>
12.325*1.05=12.94125
</span>Carol will earn per hour=$12.94 per hour

the answer is
$12.94 per hour

Sin2x-sin2xcos2x=sin4x
yaroslaw [1]

It looks like the given equation is

sin(2x) - sin(2x) cos(2x) = sin(4x)

Recall the double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

which lets us rewrite the equation as

sin(2x) - sin(2x) cos(2x) = 2 sin(2x) cos(2x)

Move everything over to one side and factorize:

sin(2x) - sin(2x) cos(2x) - 2 sin(2x) cos(2x) = 0

sin(2x) - 3 sin(2x) cos(2x) = 0

sin(2x) (1 - 3 cos(2x)) = 0

Then we have two families of solutions,

sin(2x) = 0   or   1 - 3 cos(2x) = 0

sin(2x) = 0   or   cos(2x) = 1/3

[2x = arcsin(0) + 2nπ   or   2x = π - arcsin(0) + 2nπ]

… … …   or   [2x = arccos(1/3) + 2nπ   or   2x = -arccos(1/3) + 2nπ]

(where n is any integer)

[2x = 2nπ   or   2x = π + 2nπ]

… … …   or   [2x = arccos(1/3) + 2nπ   or   2x = -arccos(1/3) + 2nπ]

[x = nπ   or   x = π/2 + nπ]

… … …   or   [x = 1/2 arccos(1/3) + nπ   or   x = -1/2 arccos(1/3) + nπ]

What does d equal ?? ​
Vlad1618 [11]

Answer:

<h2>d = 23</h2>

Step-by-step explanation:

∠IHE and ∠GHF are vertical angles.

Vertical angles have the same measures (are congruent).

Therefore, if m∠IHE = d + 44 and m∠GHF = 4d - 25, then we have the equation:

d + 44 = 4d - 25         <em>subtract 44 from both sides</em>

d + 44 - 44 = 4d - 25 - 44

d = 4d - 69            <em>subtract 4d from both sides</em>

d - 4d = 4d - 4d - 69

-3d = -69          <em>divide both sides by (-3)</em>

-3d/(-3) = -69/(-3)

d = 23
