Answer:
$4
Step-by-step explanation:
2 Bracelets + 3 rings = $26
2 rings = $12
3 rings = x
To get the cost of 1 ring you divide 12 by 2 and the answer you get is 6.
The total cost of the 3 rings is $18( $6*3)
Then you subtract the cost of both 2 bracelets and 3 rings($26) from the cost of 3 rings($18). The answer is $8. ( THIS IS THE COST OF 2 BRACELETS)
<u>1 BRACELET= $4( $8/2)</u>
 
        
             
        
        
        
The business owner should be told to angle a spotlight mounted on the roof at the angle of =39°
<h3>Calculation of angle</h3>
The distance of the flagpole from the building = 55ft
The building has the height of = 45ft
The flagpole has the height of = 25ft
The angle can be calculated using the formula;
Tan θ = opposite/adjacent
Where opposite= 45ft
adjacent = 55ft
Tan θ = 45/55 = 0.82
 θ = Tan–¹0.82
θ = 39°

She orders 5 pair in 5 different sizes:
5 x 5 = 25 pair
She orders 3 pair in 3 different sizes:
3 x 3 = 9 pair
Total pairs = 25 + 9 = 34 pair.

Answer:
<em>Expected number of students  would have a driver's license = 6</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data In a class of 25 students, 15 of them have a driver's license
The sample proportion 
                                 
Let 'X' be the binomial distribution 
Given sample size 'n' = 10
<em>mean of the binomial distribution or expected number of students  would have a driver's license</em>
                                  μ = n p 
                                     = 10 × 0.6
                                    = 6
<u><em>Conclusion</em></u>:-
<em>Expected number of students  would have a driver's license = 6</em>
