When the x-value has increased by 1 unit, the y-value has multiplied by 3, so we expect a function of the form (something)×(3^x). The last choice has that.
... f(x) = 4(3)^x
_____
You can always evaluate the offered choices at the given points to see which of them works. The second point (2, 36) will tell you the fastest.
4·3^-2 = 4/9 ≠ 36 . . . . . you can tell at this point you don't want -x as the exponent
3·4^-2 = 3/16 ≠ 36
3·4^2 = 48 ≠ 36
4·3^2 = 36 = 36 . . . . this is the one you want
The number of complex roots is 2 or 0
Answer:
The probability that the man is greater than 74 inches is 0.1587
Step-by-step explanation:
The required probability is found by evaluating the area under the corresponding distribution curve for the corresponding values
The standard normal variate factor (Z) is given by
![Z=\frac{x-\bar {X}}{\sigma }](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-%5Cbar%20%7BX%7D%7D%7B%5Csigma%20%7D)
where
is mean of the data
is the standard deviation of the data
Thus corresponding to x = 74 the Z factor equals
![Z=\frac{74-70}{4}=1](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B74-70%7D%7B4%7D%3D1)
Using the standard normal distribution table corresponding to mean of 70 and deviation of 4 the area under the curve corresponding to Z = 1 equals
0.1587
