Use simultaneous equations.
let the number of bracelets be y and necklaces be z.
so
2y + 3z = 95. this is formula 1
y + z = 37. this is formula 2
so from formula 2, we can change that to
y = 37 - z. this is formula 3
sub 3 into 1,
2 (37-z) + 3z = 95
74 - 2z + 3z = 95
z = 21
sub z = 21 into 3,
y = 37 - 21
y = 16
therefore you sold 16 bracelets and 21 necklaces
Answer:
16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes
Step-by-step explanation:
Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments
For the success of 2 experiments:
f(2) = (0.4)^2
=0.16 => 16%
For the success of 3 experiments:
f(3) = (0.4)^3
= 0.064 => 6.4%
For the success of 4 experiments:
f(4) = (0.4)^4
= 0.0256 => 2.56% => ~2.6
For the success of 5 experiments:
f(5) = (0.4)^5
= 0.01024 => 1.024% => ~1%
