The following are weights in pounds of a college sports team: 165, 171, 174, 180, 182, 188, 189, 192, 198, 202, 202, 225, 228, 235, 240 the mean is: 198 (round to the nearest whole number). the sample standard deviation is: 24 (round to the nearest whole number). the first quartile is: 180 (round to the nearest whole number). the median is: 192 (round to the nearest whole number). the third quartile is: 225 (round to the nearest whole number). find the weight that is 2 standard deviations below the mean. 150 (round to the nearest whole number). a new player who is 215 pounds wants to join the team. how many standard deviations from the mean is this new player? (round to two decimal places).

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

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
