1 answer:
The phrases that fit the graph of are
- curve positive x-values
- point (1, 1) x-intercept = 0
- quadrant I y-intercept = 0
The equation of the function is given as:
Next, we plot the graph of the function (see attachment)
From the attached graph, we have the following highlights:
- All points are in quadrant I
- The function is a curve
- It has an x-intercept of x = 0
- It has a y-intercept of y = 0
- It has only positive x values
- It passes through (1,1)
The above represents the phrases that fit the graph

Answer:
0.0104
Step-by-step explanation:
Given that, the lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard deviation of 2.6 years.
So, mean,
and standard deviation,
The z-score, for any arbitrary life span of x year, is given by
By using the given values, we have
The z-score for x=24, by using equation (i), is
From the table, the area to the left side of z=2.31 =0.98956
But, the proportion of crocodiles have lifespans of at least 24 years
= Area to the right side of the z=2.31
=1- (Area to the left side of the z=2.31)
=1-0.98956
=0.01044
So, the proportion of crocodiles that have lifespans of at least 24 years is 0.0104.
Hence, option (a) is correct.
