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

the height of the water in a fish pod is 42.5 inches . water is being drained from the pond at a rate of 3.75 inches per minute
Olenka [21]

Answer:

The height of water after 3 minutes of drain is 31.25 inches .

Step-by-step explanation:

Given as :

The initial height of water in a fish pod = i = 42.5 inches

The rate of drain of water = r = 3.75 inches per min

Let The height of water after 3 min = f inches

The time taken for water drain = t = 3 minutes

<u>Now, According to question</u>

∵ In 1 minute , The water decreases = 3.75 inches

∴ In 3 minute ,The water decreases = 3.75 inches × 3

I.e In 3 minute ,The water decreases = 11.25 inches

Now, The height of water after 3 min = initial height of water - the decrease height of wate

f = i - 11.25 inches

Or, f = 42.5 inches - 11.25 inches

or, f = 31.25 inches

So, The height of water after 3 min = f = 31.25 inches

Hence, The height of water after 3 minutes is 31.25 inches Answer
