You are given the
length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You
are required to find how many links are there in the chain. You just divide
28.9 cm by 1.7 cm to get the answer. The solution is,
<span>
Number of links =
chain length/link length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links =
chain length/link length</span>
Number of links = 17
<span><u><span>There are 17
links in a 28.9cm chain length.</span></u><u /></span>
It's 3/4
no number line provided for me, but if you find the common denominator (4), and convert 1/2 into 2/4, then adding 2/4+1/4 is easy, and equals 3/4
You need to use the binomial probability formula:

where:
n = total number of events = 10
k = number of events we are testing = 6
p = probability of event happening = 0.5

= 210×0.015625×0.0625
= 0.205078
Hence, the probability of getting 6 boys out of 10 births is
p = 0.205.
According to the question, the region is bounded by the curve with the given data as 
To compute the volume of the solid, use the disk method. The given object is rotated along the horizontal axis with the disk cross sectional area and the volume can be written as:

As per question, when x = 1 then the value of y is: y = 1
Now, substituting calculated values in the expression:

Substitute the value of the variable 'x':
Therefore, the expression can be written as:
