Answer:

Step-by-step explanation:

No, in order for a set of numbers to be a function, it has to pass the vertical line test. Draw a vertical line to see if it intersects the line more than once. Another way to think about it, is that one singular x value cannot give two different y values. That is impossible.

For example at x = 0, there are two y values that relate to that point. I'm going to estimate the y value for simplicity and the purpose of explanation.

(0,2) and (0,-4)

A wildlife preserve features a crocodile with a documented age of 24 years, believed to be one of the oldest crocodiles in capti

zysi [14]

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, $\mu=18$

and standard deviation, $\sigma=2.6$

The z-score, for any arbitrary life span of x year, is given by

$z=\frac{x-\mu}{\sigma}$

By using the given values, we have

$z=\frac{x-18}{2.6} \cdots(i)$

The z-score for x=24, by using equation (i), is

$z=\frac{24-18}{2.6}=\frac{6}{2.6}=2.31$

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.

Let angle 1 and angle 2 be complementary. If má 1 = 4x +3 and m42 = x + 2, find the measure

Andre45 [30]

Answer:

m∠1 = 71°

Step-by-step explanation:

Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.

Set the measures of the two angles equal to 90°

$(4x+3)+(x+2)=90\\$

Combine like terms

$5x+5=90$

Solve for x

$x=17$

Plug the value of 'x' back into the given equation for the measure of angle 1

$m$

m∠1 = 71°
