(1 point) according to the u. s. national center for health statistics, 25.2 percent of men and 23.6 percent of women never eat breakfast. suppose that random samples of 225 men and 225 women are taken. approximate the probability that (a) at least of 114 of these 450 people never eat breakfast: p{≥114 never eat breakfast}≈ 1-0.65910 (b) the number of the women who never eat breakfast is at least as large as the number of the men who never eat breakfast: p{women ≥men}

step-by-step explanation:

0

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
