Nts) in a certain population of voters, 72% of them plan to vote in favor of a new
Ganezh [65]

Answer:

Probability that 10 of them plan to vote against this piece of  proposed legislation is 0.0701 or 7.01 %.

Step-by-step explanation:

Consider the event of voting against the piece as success, 'p'. So, voting in favor of the piece is failure and denoted by 'q'.

Given:

Sample size is, n=25

Probability of failure is, q=72\%=0.72

Therefore, probability of success is, p=1-q=1-0.72=0.28

Number of successes is, x=10

Now, from Bernoulli's distribution, probability of x successes out of n samples is given as:

P(X=x)=_{n}^{x}\textrm{C}p^xq^{n-x}

Here, n=25,x=10,p=0.28,q=0.72. Therefore,

P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{25-10}\\P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{15}\\P(X=10)=3.269\times 10^{6}\times 2.962\times 10^{-6}\times 7.244\times 10^{-3}\\P(X=10)=70.142\times 10^{-3}=0.0701=7.01\%

Therefore, probability that 10 of them plan to vote against this piece of  proposed legislation is 0.0701 or 7.01 %.

PLZZ HELP ME 20 POINTS AND BRAINLIEST!
omeli [17]

Answer:

The price of price of the stock after it has been owned for 12 weeks is $92.55

Step-by-step explanation:

Given: The price of a particular stock is represented by the linear equation

y = -0.91x + 103.47

where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.

We have to find the price of price of the stock after it has been owned for 12 weeks.

Since , x represents the number of weeks the stock has been owned.

Thus, by substitute, x = 12

We get the value of y , the price of stocks.

Thus, y(x) =  -0.91x + 103.47

⇒ y(12) =  -0.91(12) + 103.47

⇒ y(12) =  -10.92 + 103.47

Solving , we get,

⇒ y(12) = 92.55

Thus, the price of price of the stock after it has been owned for 12 weeks is $92.55.
