The required acceleration is 0.0666 [tex]m^{2}[/tex]/s.
Given that the velocity of the object is 2m/s and time is 30s.
Acceleration is the rate of change of velocity with respect to time.
To find the acceleration by using the formula.
acceleration (a) = velocity (v) / time (t).
By using data and formula gives,
acceleration (a) = velocity (v) / time (t).
acceleration (a) = 2 / 30

1. A research poll was conducted to investigate opinions about global warming. The respondents (1 point)
who answered yes when asked if there is solid evidence that the Earth is getting warmer were
then asked to select a cause of global warming. The results were arranged between male and
female responses. Using a 0.05 significance level, a test statistic of 0.792 and a critical value of
5.991 are found. Test the claim that the gender of the respondent is independent of the choice
for the cause of global warming. State the initial and final conclusion
OReject the null hypothesis; there is not sufficient evidence to warrant rejection of the claim that the
gender of the respondent is independent of the choice for the cause of global warming.
OReject the null hypothesis; there is sufficient evidence to warrant rejection of the claim that the gender
of the respondent is independent of the choice for the cause of global warming.
Fail to reject the null hypothesis; there is not sufficient evidence to warrant rejection of the claim that
the gender of the respondent is independent of the choice for the cause of global warming.
OFail to reject the null hypothesis; there is sufficient evidence to warrant rejection of the claim that the
gender of the respondent is independent of the choice for the cause of global warming.
The initial and final conclusion would be Fail to reject the null hypothesis; there is not sufficient evidence to warrant rejection of the claim that the gender of the respondent is independent of the choice for the cause of global warming. Option C
Why does it fail to reject the null hypothesis?The initial hypothesis is that the gender of the respondent is independent of the choice for the cause of global warming.
The alternative hypothesis is that the gender of the respondent is dependent on the choice for the cause of global warming.
The test statistic of 0.792 is less than the critical value of 5.991. Therefore, we do not reject the null hypothesis.
Looking at the statistic that has been provided, we do not have enough evidence to conclude that the gender of the respondent is related to the choice of the cause of global warming at the 0.05 significance level.

DO not make it a parabola. it is basically just a straight line down, then a really long curve. Make sure you make the curve go across the entire graph.
Vertex for y=2(x-3)^2 +1
The vertex of the equation of the parabola y = 2( x - 3 )² + 1 is (3,1).
What is the vertex of the parabola?Given the equation of the parabola in the question:
y = 2( x - 3 )² + 1
To determine the vertex of the parabola, we use the vertex form of a parabola which is expressed as:
Vertex form: y = a(x - h)² + k
Where (h, k) represents the vertex of the parabola.
The given equation is already in the vertex form:
y = 2( x - 3 )² + 1
Hence, comparing the given equation, y = 2(x - 3)² + 1, with the vertex form, we can see that:
h = 3 and k = 1
Therefore, the vertex is (3,1).

In quantitative literacy, the solution involves finding the LCM of the numbers and then squaring it to obtain the smallest square number that satisfies the given conditions.
In quantitative literacy, finding the smallest square number that is divisible by 8, 12, 15, and 20.
To solve the problem, we need to determine the least common multiple (LCM) of these four numbers.
Let's list the multiples of each number until we find a common multiple:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, ...
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, ...
Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, ...
Multiples of 20: 20, 40, 60, 80, 100, 120, ...
From the lists above, we can see that 120 is the smallest common multiple of all the numbers. To find the smallest square number, we need to square 120:
120^2 = 14,400
The smallest square number that is divisible by 8, 12, 15, and 20 is 14,400.

The support beams of truss bridges are triangles. James made a model of a truss bridge with a scale of 1 inch = 4 feet. If the height of the tallest triangle on the model is 9 inches, what is the height of the tallest triangle on the actual bridge?
The height of the tallest triangle on the actual bridge is 12 feet.
If James made a model of a truss bridge with a scale of 1 inch = 4 feet, we can use this information to find the height of the tallest triangle on the actual bridge.
Let x be the height of the tallest triangle on the actual bridge. Since the scale of the model is 1 inch = 4 feet, the height of the tallest triangle on the model can be converted to feet by multiplying by 4. Therefore, the height of the tallest triangle on the model is:
9 inches * (1 foot / 12 inches) * 4 = 3 feet
We can use the similarity of triangles to set up a proportion to find x. The corresponding sides of similar triangles are proportional. In this case, the height of the triangle on the model corresponds to the height of the triangle on the actual bridge, and the scale factor from the model to the actual bridge is 1/4 (since 1 inch on the model represents 4 feet on the actual bridge). Therefore, we have:
height of triangle on model / height of triangle on actual bridge = scale factor
3 feet / x = 1/4
Multiplying both sides by x, we have:
3 feet = (1/4) x
Multiplying both sides by 4, we have:
12 feet = x

Find the equation using the point slope formula or slope intercept formula for the two sets of points. (19,-16) (-7,-15)
The equation of the Line passing through the points (19, -16) and (-7, -15) is: y = (-1/26)x - 397/26
The equation of a line using the point-slope formula or the slope-intercept form, we need either the slope of the line or the y-intercept. Let's calculate the slope of the line using the given points (19, -16) and (-7, -15).
The slope (m) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Using the coordinates (19, -16) as (x1, y1) and (-7, -15) as (x2, y2), we can substitute these values into the slope formula:
m = (-15 - (-16)) / (-7 - 19)
m = (-15 + 16) / (-7 - 19)
m = 1 / (-26)
m = -1/26
Now that we have the slope of the line, we can use either the point-slope formula or the slope-intercept form to find the equation.
Using the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept, we can substitute the slope (-1/26) and one of the given points (19, -16) into the equation:
-16 = (-1/26) * 19 + b
To solve for b, we can simplify the equation:
-16 = -19/26 + b
To isolate b, we can add 19/26 to both sides of the equation:
-16 + 19/26 = b
Now, we can find the common denominator of 26 and add the fractions:
(-416 + 19) / 26 = b
-397/26 = b
Therefore, the equation of the line passing through the points (19, -16) and (-7, -15) is: y = (-1/26)x - 397/26
This equation represents the line with a slope of -1/26 and a y-intercept of -397/26.
