If you include 4 the probability is 3/6 or 1/2. If 4 is not included it is 2/6 or 1/3. When four is included the possible numbers included are 4,5 and 6. If 4 is not included the possible numbers are 5 and 6.<span />

Solve the equation for theta (0°≤theta&lt;360°)<br><br>2 sin theta = 1​
Oduvanchick [21]

Answer:

30 degrees

Step-by-step explanation:

To figure out theta is using a bit of simple trigonometry.

2sin(theta) = 1

= sin(theta) = 0.5

Using arcsin (sin^-1) we can isolate x

x = arcsin(0.5)

x = 30

starting from 1.4 miles away a car drives towards a speed check point and then passes it the car travels at a constant rate of 5
LenKa [72]

Answer: At t=0.015 hours when the car 0.6 miles from the check point.

Step-by-step explanation:

Since we have given that

Distance traveled by him towards a speed check point = 1.4 miles

Speed at which he is travelling = 52 miles per hour

Let the time taken by him be x

Since we have the equation

d=1.4-52t

where<em> </em><em>d</em><em> </em>denotes distance

and <em>t </em>denotes time.

If we have given that the car 0.6 miles from the check point.

So, we put the value of <em>d</em> in place of it .

0.6=1.4-52t\\\\0.6-1.4=-52t\\\\-0.8=-52t\\\\0.8=52t\\\\\frac{0.8}{52}=t\\\\0.015=t

So, at t=0.015 hours when the car 0.6 miles from the check point.

Please show ALL work<br><br> 4-5(2x+11)+6x=6-4(-x-9)-5
svp [43]

Step 1. Simplify 6 - 4(-x-9)-5 to -4(-x-9) + 1

4 - 5(2x + 11) + 6x = -4(-x-9) + 1

Step 2. Expand

4 - 10x - 55 + 6x = 4x + 36 + 1

Step 3. Simplify 4 - 10x - 55 + 6x to -51 - 4x

-51 - 4x = 4x + 36 + 1

Step 4. Simplify 4x + 36 + 1 to 4x + 37

-51 - 4x = 4x + 37

Step 5. Add 51 to both sides

-4x = 4x + 37 + 51

Step 6. Simplify 4x + 37 + 51 to 4x + 88

-4x = 4x + 88

Step 7. Subtract 4x from both sides

-4x - 4x = 88

Step 8. Simplify -4x - 4x to -8x

x = -88/8

Step 10. Simplify 88/8 to 11

x = -11
