i think it is 27
Step-by-step explanation:
Answer:
y - 1 = (1/3)(x - 3)
Step-by-step explanation:
By inspection we see that if x increases by 6, y increases by 2. Thus, the slope of the line connecting 2 or more of these points is m = 2/6, or m = 1/3.
Using the point-slope formula y - k = m(x - h), we substitute 1/3 for m, 3 for h and 1 for k, obtaining:
y - 1 = (1/3)(x - 3)
Answer:
a. -1.35
b. 0.177016
Step-by-step explanation:
According to the question, following data is given
Brown eyes american percentage is 45
Random sample be 80 out of which 30 had brown eyes
Based on the above information
The computation is shown below:
a. The proportion of the sample is
![\bar p = \frac{30}{80}\\\\= 0.375](https://tex.z-dn.net/?f=%5Cbar%20p%20%3D%20%5Cfrac%7B30%7D%7B80%7D%5C%5C%5C%5C%3D%200.375)
The z value is
![z = \frac{\bar p - p }{\sqrt{\frac{p(1 - p)}{n} } } \\\\\frac{0.375-0.45 }{\sqrt{\frac{0.45(1 - 0.45)}{80} } }](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%5Cbar%20p%20-%20p%20%7D%7B%5Csqrt%7B%5Cfrac%7Bp%281%20-%20p%29%7D%7Bn%7D%20%7D%20%7D%20%5C%5C%5C%5C%5Cfrac%7B0.375-0.45%20%7D%7B%5Csqrt%7B%5Cfrac%7B0.45%281%20-%200.45%29%7D%7B80%7D%20%7D%20%7D)
= -1.35
b Now the P value is
As z comes -1.35
So, there is a two tailed p value i.e. 0.177016
Answer:
C; In fifteen hours, the pilot can fly 4,050 miles.
Step-by-step explanation:
Okay, so distance = rate*time.
To find the rate, divide the distance by time.
540/2 = 270.
So, at this rate the pilot can fly 270 miles every hour. 270*15 = 4,050.
