Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically, 
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7
 
        
             
        
        
        
Answer:
21/50, 42%
Step-by-step explanation:
The total times the coin was flipped is 50 and the number of times it landed on tails is 50-29=21. So we need to divide 21 by 50, which gives us 42%.

Answer:
The answer to your question is letter D
Step-by-step explanation:
Formula
                      m∠E = 
Data
m∠E = 48°
DGF = 228°
DF = x°
Substitution
                     48° = 
Solution
                                      2(48) = 228 - x°
                                      96 = 228 - x°
                                      96 - 228 = - x°
                                     - 132 = - x°
                                        x° = 132°
 
        
             
        
        
        
Answer:
A 21 /169
B independent
Step-by-step explanation:
The total number of candies is 7+3+3 = 13
P( 1st red) = red/total = 7/13
Since the candy is put back there are still 13 candies in the dish
P(2nd green) = green/total = 3/13
P( red, then green) = P( 1st red) * P(2nd green)
                                 = 7/13* 3/13 = 21/169
The events are independent since the candies are put back
