For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield x overbarequals6.4, y overbarequals6.0, requalsnegative 0.236, P-valueequals0.100, and ModifyingAbove y with caretequals7.65negative 0.263x. Find the best predicted value of ModifyingAbove y with caret (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is xequals5. Use a 0.01 significance level.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

1. minimum

2. 6400

3. eight

hope this !

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

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
