Question 24 pts Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches. What is the probability that a randomly selected male is more than 74 inches tall? Enter you answer in decimal form, e. g. 0.68, not 68 or 68%.

right

step-by-step explanation:

answer:   y=2x-3

step-by-step explanation:

x = 3 ± √(5+y)

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
