Answer:
true?
Step-by-step explanation:
Answer:
There are 76 students:
g + b = 76
girls is 13 more than twice the boys:
g = 2b + 13
replace g with 2b + 13 in 1st equation
2b+13+b = 76
3b + 13 = 76
3b = 63
b = 21 boys
g = 76-21 = 55 girls
Step-by-step explanation:
Turn 2 3/4 to an improper fraction (2*4+3=11/4). Then turn your new improper fraction to the reciprocal (switch the two numbers (4/11). Change the division sign to multiplication (3/16*4/11). Then multiply across (12/176). Then simplify by 4 to get. 3/44.
THis is a binomial distribution:-
P( 3 tails) = 15C3 (0.5)^3(0.5)^12
= 0.0139
P(5 tails) = 15C5 (0.5)^5(0.5)^10
= 0.0916
P(3 or 5) = 0.0139 + 0.0916 = 0.1055 Answer
