Step-by-step explanation:
15) 50 ÷ 2 = 25 
17) Mean = 301, Mode = 40-50 
 
 (10+20) ÷ 2 = 15, (20+30) ÷ 2 = 25, (30+40) ÷ 2 = 35 
 (40+50) ÷ 2 = 45, (50+60) ÷ 2 = 55, (60+70) ÷ 2 = 65
 (70+80) ÷ 2 = 75 
• 15×4 = 60, 25×8 = 200, 35×10 = 350, 45×12 = 540
 55×10 = 550, 65×4 = 260, 75×2 = 150 
Mean = (60+200+350+540+550+260+150) ÷ 7 
 = 2110 ÷ 7
 = 301.4285....
 = 301 
Mode : the highest frequency
 
        
                    
             
        
        
        
Answer:
A loss of weight means we subtract from Jack's current weight. 
Step-by-step explanation:
A loss of weight means we subtract from Jack's current weight. New Weight = Current Weight - Weight Loss per week * number of weeksNew Weight =257 - 3*12New Weight =257 - 36New Weight = 221
 
        
                    
             
        
        
        
2. There are 18 other bottles in the fridge, because .6 of 30 is 18. 30 – 18 is 12, so there are 12 bottles of orange juice and cranberry juice.
4. If the probability of an event is 25%, then the probability of <em>not</em> that event is the other part of 100%. In other words, 1 – .25 = .75.
        
             
        
        
        
13) Angle 1= 54 Angle 2=36
14) Angle 1=122 Angle 2=58
