The opposite of
blondinia [14]

Answer:

False.

Step-by-step explanation:

Integers are numbers in this set:

{...,-3,-2,-1,0,1,2,3,...}

The opposite of a number is you just changing the sign of that number. Unless you are asking for the opposite of 0 which is just 0.

Example: The opposite of 5 is -5.

Example: The opposite of -5 is 5.

So the opposite of an integer does not always mean the result will be negative. As you seen above, it could be 0, positive, or negative.

It is estimated that 4000 of the 10,000 voting residents of a town are against a new sales tax. If 15 eligible voters are select
Alenkasestr [34]

Answer:

The probability that at most 7 favor the new tax is 0.7869

Step-by-step explanation:

Total number of voting resident = 10000

number of voting resident against new sales tax = 4000

therefore probability of choosing a voting resident against new sales tax = 4000/10000 = 0.4

If 15 eligible voters are selected at random and asked their opinion, what is the probability that at most 7 favor the new tax

Using binomial,

number of selected voters(n) =15,

p=0.4

P(x<=0.7) = binomialcdf(15, 0.4, 7)

Using your calculator

P(x<=0.7) = binomialcdf(15, 0.4, 7) = 0.7869
