Answer:
42
Step-by-step explanation:
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(3)
A = 3
<u>Area of rectangle:</u>
A = bh
A = 11(3)
A = 33
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(3)(4)
A = 6
<u>Combined:</u>
3 + 33 + 6
42
Answer:
time walking=1-t hrs
ditace is same
therefore 2.5*(1-t)=45*t
2.5-2.5t=45t
t=2.5/46.5 hrs
this has only one solution since it is in linear form
Answer: The probability that the project will be completed in 33 days or less is equal to<u> </u><u>0.73</u> .
Step-by-step explanation:
We assume that this is a normally distribution.
Given : The critical path length is 30 days .
i.e. Population mean = 
Variance : 
Then, standard deviation : 
Z-score : 
The value of z corresponding to 33 = 
Now, the p-value = 
Hence, the probability that the project will be completed in 33 days or less is equal to 0.73.
Answer:
Step-by-step explanation:
The surface area of a cylinder is 2pi *rh + 2pir^2, where r and h are radius and height, respectively. (If you want me to explain this, comment down below). Anyways, we can simply plug in 11 and 8 in the formula, so 2* 8*11*pi + 2* pi * 8^2=304pi. Thus, we do 304 * 3.14=954.56.
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is : 
Now, general form of the equation of the circle is:

where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get

So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
