The average number of accidents is 3 per month, what is the probability of 1 accident?
tatuchka [14]
<h2>Hello!</h2>

The answer is: 33.33%

<h2>Why?</h2>

Since we have the average number of accidents that occurs in 1 month, and it's equal to 3, we can calculate the probability of 1 accident occurs by dividing it into the average number of accidents, using the following formula:

Probability=\frac{FavorableOutcomes}{Outcomes}*100

Where,

Favorable outcomes are the occurrence of the event, for this case, it's equal to 1.

Outcomes are the possible occurrence of the event, for this case, it's equal to 3.

So, by substituting we have:

Probability=\frac{1}{3}*100

Probability=0.3333*100=33.33

So, the probability will be equal to 33.33%

Have a nice day!

Given a right ?ABC, where AB = 4.5 cm, BC = 7.794 cm, and AC = 9 cm, sketch the triangle below, and find the measure m?C in degr
Ksju [112]

Answer:

The measure of angle C is 30\°

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

sin(C)=\frac{AB}{AC}

substitute the values

sin(C)=\frac{4.5}{9}

C=arcsin(\frac{4.5}{9})=30\°

Find the distance between the pair of points: (6,−3) and (1,0
rosijanka [135]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\sqrt{34}

»»————- ★ ————-««  

Here’s why:

⸻⸻⸻⸻

\text{\underline{The distance formula is:}}\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⸻⸻⸻⸻

\boxed{\text{Calculating the answer....}}\\\\d = \sqrt{(1-6)^2+(0-(-3))^2}\\--------------\\\rightarrow d = \sqrt{(-5)^2+(3)^2}\\\\\rightarrow d = \sqrt{(25+9)}\\\\\rightarrow d =\boxed{ \sqrt{34} }

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

*PLS HELP*<br>I need help on this and please provide an explanation<br>​
expeople1 [14]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>9</u></em></h2>

Step-by-step explanation:

<h3><em><u>To</u></em><em><u> </u></em><em><u>Find</u></em><em><u>:</u></em><em><u>-</u></em></h3>
  • Value of x

<h3><em><u>Given</u></em><em><u>:</u></em><em><u>-</u></em></h3>
  • 46° and (5x - 1)° are complementary angles

<h3><em><u>Solution</u></em><em><u>:</u></em><em><u>-</u></em></h3>

As we know,

Complementary angles:

The angles whose sum results to 90° are known as the <em><u>complementary</u></em><em><u> </u></em><em><u>angles</u></em><em><u>.</u></em><em><u> </u></em>

So,

46° + (5x - 1)° = 90°

  • <em>[</em><em>Since</em><em> </em><em>complementary</em><em> </em><em>angles</em><em>]</em>

=> 46 + 5x - 1 = 90

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 45 + 5x = 90

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>45</em><em>]</em>

=> 45 + 5x - 45 = 90 - 45

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 5x = 45

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>5</em><em>]</em>

=  >  \frac{5x}{5}  =  \frac{45}{5}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> x = 9

<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>required</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>9</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
