Simplified expression is 11y² + 6x - 13
Step-by-step explanation:
- Step 1: Simplify 5y² + 3y - 13 + 6x - 3y + 6y²
5y² + 3y - 13 + 6x - 3y + 6y² = 11y² + 6x - 13
The two angles are 155 degrees and 25 degrees
<h3><u>
Solution:</u></h3>
Given that two supplementary angles are in ratio 31 : 5
Let the first angle be 31a
Let the second angle be 5a
Two Angles are Supplementary when they add up to 180 degrees.
Therefore,
first angle + second angle = 180 degrees

<em><u>Therefore the angles are:</u></em>
first angle = 31a = 31(5) = 155 degrees
second angle = 5a = 5(5) = 25 degrees
Thus the two angles are 155 degrees and 25 degrees

Given
Electrician = 6
Mechanic = 8
Required
Determine the probability of selecting an electrician
First, we need the total number of employees;



Next, is to determine the required probability using the following formula;


Divide numerator and denominator by 2

<em>Hence, the probability of selecting an electrician is 3/7</em>
Answer:
The IQR is the best measurement of spread for games and movies.
Step-by-step explanation:
Because both seem to have outliers, we want to use IQR instead of standard deviation to determine the spread of data.
