Answer: The required probability is 2.167.

Step-by-step explanation:

Since we have given that

It is a uniform distribution between 46 minutes and 73 minutes.

She finishes within 58.5 minutes.

So, the general probability is :

\dfrac{58.5}{b-a}\\\\here,\\\\a=46\\\\b=73

So, the probability would be

\dfrac{58.5}{73-46}=\dfrac{58.5}{27}=2.167

Hence, the required probability is 2.167.

Solve the following system: y = x 3 4x y = 18 (6, 3) (3, 6) (â’3, 6) (3, â’6).
Nastasia [14]

The solution of the given equation is (3,6). The correct option is B.(3,6)

<h3>Given equations,</h3>

y=x+3.......(1)\\4x+y=18.....(2)

<h3>How to solve the equations?</h3>

putting the value of y from equation (1) in equation (2) , we get

4x+x+3=18\\5x=18-3\\5x=15\\x=3

substitute the value of x=3 in equation (1) we get,

y=3+3\\y=6

Hence, the solution of given equation is (3,6).

So, the correct option is B.

Convert the angle 61 38’ 45” to decimal degrees, and round to the nearest hundredth of a degree
slega [8]
A suitable calculator* can do this easily.

61°38'45" = (61 +(38 +45/60)/60)° ≈ 61.65°

_____
I like the RealCalc app for Android, but many graphing calculators also will do this conversion. Of course, you can simply evaluate the expression as above.
