Which of the following is the best evidence of an association between scoring
40 points or more and the rugby team winning a game?

Answers

The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The rugby squad from Bimini High School won the state title that year. A record of their wins and losses is shown, in which the relationship between wins and losses is sorted by the number of points scored. From observation, The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

Thus, the best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

Answer:

156 for the first, 14 for the second

Step-by-step explanation:

x = -5 y=4

Plug in (first equation)

(4(4))^2 - (2(-5))^2

(16)^2 - (-10)^2

256-100

156

Second Equation

4y^2-2x^2

Plug in

4(4)^2 - 2(-5)^2

4(16) - 2(25)

64-50

Parenthesis make a huge difference

Prove the identity
2sin^2x - 1 = sin^2x - cos^2x

Answers

Hello,

sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================

From the trigonometric identity:

$cos^(2)x + sin^(2) x$ =1
Making $sin^(2)$ x the subject we get:
$sin^(2)$ x=1- $cos^(2)$ x
On evaluating the left hand side and replacing $sin^(2)$ x with 1- $cos^(2)$ x;
2(1- $cos^(2)$ x)-1
This gives

=2-2 $cos^(2)x$ -1
=1-2 $cos^(2)$ x
From the identity in $cos^(2)$ x+ $sin^(2)$ x=1, replace 1 in the equation to get;
$cos^(2)$ x+ $sin^(2)$ x-2 $cos^(2)$ x
= $sin^(2)$ 2x- $cos^(2)$ x

Find the slope of 2x-9y=-36? please show steps thank you

Answers

what I do first (easier for me) is to change it into slope-intercept form
2x-9y=-36
-9y=-2x-36                2x
---------------   =    y= ---- +4
        -9                       9
the slope is whatever is in front of x, in this case 2/9

$2x-9y=-36\n-9y=-2x-36\ny=(2)/(9)x+4\n\n\boxed{m=(2)/(9)}$
