3 0

Answer: 3

Step-by-step explanation:

Given

f(x)=\dfrac{1}{3}3^x

g(x)=2x+4

For f(x) to be true, the domain is given by observing the graph of two i.e. x\in (-1.981,3.117). In this range g(x) is greater than f(x).

From the above domain largest integer that can satisfy the condition is 3.

recent survey found that 71​% of all adults over 50 wear glasses for driving. In a random sample of 30 adults over​ 50, what is
valentina_108 [34]

Answer:

Mean = 21.3

Standard Deviation = 2.48

Step-by-step explanation:

We are given the following in the question:

p = 71​% = 0.71

Sample size, n = 30

We have to find the mean and the standard deviation of those that wear​ glasses.

\text{Mean} = np\\=30(0.71)\\=21.3

Thus, the mean of those who wear glasses is 21.3

\text{Standard deviation} = \sqrt{npq}\\=\sqrt{np(1-p)}\\=\sqrt{30\times 0.71\times (1-0.71)}\\=2.48

Thus, the standard deviation of those who wear glasses is 2.48
