An experiment to compare the tension bond strength of polymer latex modified mortar (Portland cement mortar to which polymer latex emulsions have been added during mixing) to that of unmodified mortar resulted in x = 18.19 kgf/cm2 for the modified mortar (m = 42) and y = 16.87 kgf/cm2 for the unmodified mortar (n = 32). Let m1 and m2 be the true average tension bond strengths for the modified and unmodified mortars, respectively. Assume that the bond strength distributions are both normal.

Answer:
7/20
Step-by-step explanation:
You have to add 1/4 and 2/5 which gets you 13/20. And since the glass would be full, 20/20 is full, so then you have to subtract 20/20 from 13/20 which gives you 7/20.

the figure below is a net for a triangular prism (Help)
Answers
Answer:
368 in²
Step-by-step explanation:
Surface area of the triangular prism is the sum of the area of each net = 2(area of two triangle) + 2(area of two similar rectangles) + area of rectangle
= 2(½*bh) + 2(L*W) + (L*W)
Surface area = 2(½*5*7) + 2(15*8.6) + (15*5)
= 35 + 258 + 75
= 368 in²

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 60 m, find its length and width.
Answers
Answer:
120 m
Step-by-step explanation:
.
Answer:
length = 20m
width = 10m
Step-by-step explanation:
perimeter = 2 (length + width)
length = 2 * width = 2w
perimeter = 2 (2w +w)
perimeter = 2(3w)
60m = 6w
(divide both sides by 6)
60/6 = w
width = 10m
length = 2w
so length = 2 * 10 = 20m

What is the slope of y = 4 - 2x?
Answers
Answer:
The slope is -2
Step-by-step explanation:
Rewrite in slope-intercept form.
The slope-intercept form is y = mx + b, where m
is the slope and b is the y-intercept.
[tex]y = mx + b[/tex]
Reorder 4 and -2x.
[tex]y = - 2x + 4[/tex]
Using the slope-intercept form, the slope is −2.
[tex]m = - 2[/tex]
Hence, the slope is -2.
The equation y = 4- 2x has a slope of -2.
The pitch of a direct equation is the measure of the term containing the independent variable( in this case," x").
In the equation y = 4- 2x, the measure of "x" is-2. thus, the pitch of the equation is-2.
We know equation is in slope-intercept form (y = mx + b), where "m" represents the slope.
The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).
In this case, for every unit increase in x, the value of y diminishments by 2 units. This indicates a downcast pitch.
In summary, the equation y = 4- 2x has a slope of -2.

What is Adding functions
Answers
Answer:
Adding two functions is like plotting one function and taking the graph of that function as the new x-axis. Points of the second function are then plotted with respect to the new axis. For example, (2, 3) becomes "over 2," "up 3 from the new axis," or (3, f + 2).
Another Example:
To add or subtract functions, just add or subtract the values at each point where it makes sense. If the functions are given by formulas, you can just add or subtract the formulas (it doesn't matter whether you plug in values before or after).

Answer:
Equation y =2x represent the direct variation .
Step-by-step explanation:
Given : Equations y = 2x , y = x + 4 , y = 1/2x , y = 3/x .
To find : Which equation represents a direct variation.
Solution : We have given that equations
Direct variation : The statement "y varies directly as x," mean y and x always have the same ratio: k = .
Where k is constant of variation ,
We can write it as y = kx .
We can see that in equation y = 2x is the same as the above equation
On comparing k = 2.
Therefore, Equation y =2x represent the direct variation .

Step-by-step explanation:
it should.look something like this tho for x>-2
The graph that shows x > -2 is graph B.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
In graph B, the line at x = -2 is an open circle, which means that the point x = -2 is not included in the range of the graph. The line to the right of x = -2 shows all the possible values of x that are greater than -2.
In graph A, the shaded region includes the point x = -2, which means that x ≥ -2. This is not what we want because we want x > -2.
In graph C, the shaded region includes the line at x = -2, which means that x ≥ -2. This is also not what we want because we want x > -2.
In graph D, there is not enough information to determine the range of x values that satisfy x > -2.
Therefore, the correct graph is represented by option B.
