9 x 9 = 81
81 - 21 = 60
60 / -6
10
Answer:
(-84) and (-83).
Step-by-step explanation:
1) according to the condition 'two conscutive integers' means x and x+1;
2) according to the condition x+(x+1)=-167;
3) if to solve this equation, then
x= -84, it means the required integers are: (-84) and (-83).
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%
