The best thing to do is to divide 78 by 100, and then multiply this by 9.5
78/100= 0.78. 0.78x9.5=7.41
You've then got to add 7.41 to 78, and this gives you 85.41
Hope this helps :)
“10 more that” means “add 10 to something”
“twice” means “multiply something by 2”
Use “x” or another variable for “a number”
Twice a number: 2*x or 2x
10 more than twice a number: add 10 to 2x
Answer: 2x+10
Necessary and sufficient conditions for application of binomial distribution :
1. trial must be Bernoulli, i.e. exactly two outcomes (defective or not defective)
2. number of trails is known and not dependent on outcomes (2).
3. probability of each trial must be known and is constant throughout trials (3/10, with replacement)
4. all trials are random and independent of each other.
The quotient of 2 non-zero integers is seldom another integer.
In fact, the quotient is another integer ONLY when the divisor
is a factor of the dividend.
