I really need help I don’t understand how to do this
krek1111 [17]

Answer:

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x           Multiply both sides by x

x*sin(8) = 1817             Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

÷

sin(8)

=

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).

Suppose that nine-digit Social security numbers are assigned at random. If you randomly select a number, what is the probability
Rina8888 [55]

Answer:  0.3 .

Step-by-step explanation:

The digits in number system = 10      ( 0 to 9)

The total different nine-digit Social security numbers  = 10^9  [By Fundamental counting principle]

=1,000,000,000   = 1 billion

Total people in united state = 300 million = 300, 000 ,000

Since each person In US have equal chance to get chosen.

Therefore , if a number is selected randomly  , then the probability that it belongs to one of the 300 million people in the United States :-

=\dfrac{300, 000 ,000}{1,000, 000 ,000}=0.3

Hence, the required probability is 0.3 .
