Answer:
a) 256 ft^2 No
b) 150 ft^2 Yes
c) 300 ft^2 NO
d) 192 ft^2 Yes
w=8.5 in
l=11 in
A=w•l
A=8.5•11=93.5 in^2
Scale:
1in:1.5 ft
1in^2:2.25 ft^2
1in ^2. 2.25ft^2
93.5 in^2. Xft^2
X=2.25•93.5
X=210.375

This problem is odd in that no information is given regarding the relationship, if any, between x and y, and (more importantly) x can't have both values -15 and 21. Please go back and ensure that you have copied down this problem precisely as it was given you.
Answer:
68.268%.
Step-by-step explanation:
Let \mu be the mean pregnancy length.
The given standard deviation,
days
The z-score:
z=\frac{x-\mu}{\sigma}
where x is any pregnancy length.
The range of x within 7 days of the mean pregnancy length is

z-score for this range is:


So, the area on the normally distributed curve for the above range of z-score will give the expected percentage of birds to occur within 7 days of the mean pregnancy length.
Now, from the z-score table:
The area from
to z=1 is 0.84134
and the area from
to z=-1 is 0.15866.
So, the area for -1<z<1
=0.84134 - 0.15866
=0.68268
Hence, the percentage of births would be expected to occur within 7 days of the mean pregnancy length=68.268%.
Answer:
73.27 km/hr
Step-by-step explanation:
The fastest human sprinter sprints 100 metres in 9.58 seconds. Thus, speed of sprinter is;
V_sprinter = 100/9.8
V_sprinter = 10.204 m/s
Now, from conversion, 1 m/s = 3.6 km/hr
Then, 10.204 m/s = (10.204 × 3.6)/1 = 36.73 km/h
The cheetah sprints 110 km/hr
Thus, the cheetah is faster by: 110 - 36.73 = 73.27 km/hr
