Suppose that a survey asks a random sample of 1500 adults in Ohio if they support an increase in the state sales tax. Suppose th

MrMuchimi

Answer:

Option D) 0.1935

Step-by-step explanation:

We are given the following information:

We treat adults in Ohio support the increase as a success.

P(Adults in Ohio support the increase) = 40% = 0.4

Then the number of adults follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 7

P(exactly 4 people support the increase in tax)

$P(x = 4)\\\\= \binom{7}{4}(0.40)^4(1-0.40)^3\\\\= 0.1935$

0.1935 is the probability that exactly 4 out of 7 adults in Ohio suppert the increase.

Thus, the correct answer is

Option D) 0.1935

If T equals 1 / r + 1 / s equals r + S over RS, then what is 1 / T in terms of R&S?

Thepotemich [5.8K]

$T=\dfrac{1}{r}+\dfrac{1}{s}\\\\T=\dfrac{1\cdot s}{r\cdor s}+\dfrac{1\cdot r}{r\cdot s}\\\\T=\dfrac{s}{rs}+\dfrac{r}{rs}\\\\T=\dfrac{s+r}{rs}\to\dfrac{1}{T}=\dfrac{rs}{s+r}$
