Answer:

Gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260

Step-by-step explanation:

According to the given sample there was a total of 200(92+56+52) fish collected from a lake.

Of those, 52 were gar.

52/200 = 0.26 = 26%

i.e. 26% of the total fishes collected were jar

So, if 1000 fish are collected

26% of 1000 = $\dfrac{26}{100}\times 1000$

= 260

i.e. 260 fishes were jar

Hence, gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260

There was a total of 200 fish collected and released from the pond...of those, 52 were gar......52/200 = 0.26 = 26%

so if 1000 fish are collected....26% of 1000 = 0.26(1000) = 260 gar <==

Which function is a quadratic function? u(x) = –x 3x2 – 8 v(x) = 2x2 8x3 9x y(x) = x2 3x5 4 z(x) = 7x2 2x3 – 3.

Komok [63]

The function $u(x)=-x+3x^{2} -8$ is a quadratic function due to the highest exponent being 2.

Given functions are:

$u(x)=-x+3x^{2} -8$

$v(x)=2x^{2} +8x^3+9x$

$y(x)=x^{2} +3x^5+4$

$z(x) =7x^{2} +2x^3-3$

<h3>What is a quadratic function?</h3>

A function of the form $f(x)=ax^{2} +bx+c$ with $a\neq 0$ is called a quadratic function means the highest exponent of polynomial should be 2.
