Answer:
916.1 cm^3 
Step-by-step explanation:
1) find the radius of the cylinder: 
radius = dimater / 2 = 7,3 / 2 = 3.65 cm 
2) find the base area of the cylinder: 
base area = radius^2 x 3.14 = 3.65^2 x 3.14 = 41.83265 cm^2 
3) find the height of the cylinder: 
height = 7.3 x 3 = 21.9 cm 
4) find the volume 
V = base area x height = 41.83265 x 21.9 = 916.135035 cm^3
5) round to nearest tenth: 
916. 1 cm^3 
 
        
             
        
        
        
Answer:
The probability that 75% or more of the women in the sample have been on a diet is 0.037.
Step-by-step explanation:
Let <em>X</em> = number of college women on a diet.
The probability of a woman being on diet is, P (X) = <em>p</em> = 0.70.
The sample of women selected is, <em>n</em> = 267.
The random variable thus follows a Binomial distribution with parameters <em>n</em> = 267 and <em>p</em> = 0.70.
As the sample size is large (n > 30), according to the Central limit theorem the sampling distribution of sample proportions ( ) follows a Normal distribution.
) follows a Normal distribution.  
The mean of this distribution is:

The standard deviation of this distribution is: 
Compute the probability that 75% or more of the women in the sample have been on a diet as follows:

**Use the <em>z</em>-table for the probability.

Thus, the probability that 75% or more of the women in the sample have been on a diet is 0.037.

Y-intercept means x=0 but judging from the question you only gave f(x) which means Y
And so I think the only valid answer there is 
Y= 0.25
X=0
