What happened in the first questions doesn't influence the final question, so the probability is simply 1/5 = 0.2

Please help me ASAP this is a quiz and I need a good grade I will give you five stars if you can answer this
Semenov [28]

Answer:

202 meters

Step-by-step explanation:

Since this is a right triangle, you can plug it into Pythagoras theorem of a squared plus b squared equals c squared. So 198 squared plus 40 squared equals 40804. Square root this and it gives you 202 meters.

Can someone please tell me how to do these problems
kow [346]
These are so easy, you won't believe it !

A negative exponent only means

       "Put all of this in the denominator, and make the exponent positive."

So    (any number)^negative power =

                     1 / (the same number)^(the same power but not negative) .

The first few problems on that sheet:

1).  5^-3  =  1 / 5^3

2).  6^-10  =  1 / 6^10

3).  (-2)^-5  =  1 / (-2)^5

Got it ?    You can do the rest of them now in about 2 minutes.

Select the correct answer.
Sonja [21]

Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

<em>Apple the distributive property.</em>

21 - 4i - 1 * 16 - (7i) + 28i

<em>Multiply -1 by 16.</em>

21 - 4i -16 - (7i) + 28i

<em>Multiply 7 by -1.</em>

21 - 4i - 16 - 7i + 28i

<em>Now simplify by adding terms :)</em>

<em>Subtract 16 from 21.</em>

5 - 4i - 7i + 28i

<em>Subtract 7i from -4i.</em>

5 - 11i + 28i

<em>Add -11i and 28i.</em>

= 5 + 17i
