Answer:
t-test for difference in slopes
no association exists
Step-by-step explanation:
t-test can be used to determine signifiance in difference in slopes of of fit vs time and not fit vs time graph
The data shows that as number of hours spent watchnig television increases, there is no increasing or decreasing trend in number of people fit or not fit. The number of people fit or not fit seems to be distributed around 629 for 1-2 hours of watching television. There trend is not consistent in both cases with increasing number of hours
Answer:
The Pacific is <u>2 times</u> as large as the Atlantic.
Step-by-step explanation:
Given:
The area of the Pacific is about 64 million square miles and the area of the Atlantic Ocean is approximately 32 million square miles.
Now, to find the Pacific is how many times as large as Atlantic.
<em>The area of the Pacific = 64 million square miles.</em>
<em>The area of the Atlantic = 32 million square miles.</em>
So, to get the times larger is Pacific than Atlantic we divide both the areas:
![\frac{The\ area\ of\ Pacific}{The\ area\ of\ Atlantic}](https://tex.z-dn.net/?f=%5Cfrac%7BThe%5C%20area%5C%20of%5C%20Pacific%7D%7BThe%5C%20area%5C%20of%5C%20Atlantic%7D)
![=\frac{64\ million\ square\ miles}{32\ million\ square\ miles}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B64%5C%20million%5C%20square%5C%20miles%7D%7B32%5C%20million%5C%20square%5C%20miles%7D)
![=2.](https://tex.z-dn.net/?f=%3D2.)
Therefore, The Pacific is 2 times as large as the Atlantic.
<h2>2x³ - 3x² - 8x -3</h2><h2>---------------------------</h2>
<u>Step-by-step explanation:</u>
(x-3)(2x+1)(x+1)
(2x² - 6x + x - 3)(x+1)
(2x² - 5x - 3) (x+1)
2x³ -5x² -3x + 2x² -5x - 3
2x³ - 3x² - 8x -3

The value of f(8) and x is 28 and 4 respectively
<h3>Function and values</h3>
From the coordinate point (x, y), we can use the coordinate points (0,4) and (4,8)
For the sequence 0, 4...
f(x) = a +(x-1)d
f(x) = 0 + (x-1)(4)
f(x) = 4x-4
If the value of x is 8
f(x) = 4(8) - 4
f(8) = 32 -4
f(8) = 28
If the value of f(x) is 12
12 = 4x-4
16 = 4x
x = 4
Hence the value of f(8) and x is 28 and 4 respectively

Answer:
B. Infinitely Many
Step-by-step explanation:
Step 1: Distribute
5x + 48 + 7x = 12x + 48
Step 2: Combine like terms
12x + 148 = 12x + 48
If the 2 lines are the same, which they are, they are the same lines. That means there are an infinite amount of solutions. If they had the same slope but different y-intercepts, there would be no solutions because the lines are parallel. Any other pair of equations would have 1 solution.
