Answer:
The first one (46.25)
Step-by-step explanation:
All you had to do was length times width.
Answer:
The answer is 46.25
Step-by-step explanation:
The formula for the area of a parallelogram is base times height. The base is 12.5. The height is not the diagonals on that straight line pictured on the shape, which is 3.7. 12.5 times 3.7 is 46.25
In a recent survey of 79 heads of household, 46 said they did online banking on their cell phones. Find the standard error for the sample proportion of heads of household who do online banking on their cell phones. Enter your answer as a decimal rounded to three decimal places.
Answer:
[tex]SE_p = 0.055[/tex]
Step-by-step explanation:
Given
[tex]n = 79[/tex] --- Heads
Proportion, p = 46 out of 79
Required
Determine the standard error for sample proportion (SEp)
This is calculated using the following formula
[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]
In this case:
[tex]p = \frac{46}{79}[/tex]
[tex]p = 0.5823[/tex]
Substitute values for p and n in:
[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]
[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]
[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]
[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]
[tex]SE_p = \sqrt{0.00307881911}[/tex]
[tex]SE_p = 0.0554871076[/tex]
[tex]SE_p = 0.055[/tex] ---- Approximated

write an equation that reflects this relationship using X to represent the amount of grams in fish and y to represent the number of calories
Answer:
[tex] y = \frac{3}{2}x [/tex]
Step-by-step explanation:
The graph shows there is a proportional relationship between amount of grams of fish (x) and number of calories (y).
A original relationship can be represented by An equation as [tex] y = kx [/tex], where, k = constant of proportionality (y/x).
The constant of proportionality using any point, let's say (200, 300), would be:
k = y/x = 300/200 = ³/2
Plug in the value of k into [tex] y = kx [/tex].
Thus, the equation that reflects the relationship would be:
[tex] y = \frac{3}{2}x [/tex]
The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x) and this can be determined by using the point-slope form of a line.
Given :
A graph where the x-axis represents the number of fish in grams and the y-axis represents the number of calories.Points - (100,150) and (200,300)The point-slope form can be used to determine the equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories.
The point-slope form is given by the equation:
[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex] ----- (1)
where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.
Now, put the values of [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the equation (1).
[tex]\dfrac{y-150}{x-100}=\dfrac{300-150}{200-100}[/tex]
[tex]2(y-150)=3(x-100)[/tex]
2y - 300 = 3x - 300
2y - 3x = 0
2y = 3x
The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x).

Answer:
L = 3x cm
Step-by-step explanation:
For this problem, let's consider the relation that is stated:
Length is 3 times as much as the width. The width is x cm.
Mathematically we can say the following:
L = 3W
W = x cm
So we can say the following about the length:
L = 3W
L = 3(x cm)
L = 3x cm

The line segment joining A(6, 3) to B(–1, –4) is doubled in length by having half its length added to each end. Find the coordinates of the new ends.
Answer:
(9.5, 6.5) and (-4.5, -7.5)Step-by-step explanation:
Let the extended points be A' and B' and add the point M as midpoint of AB
Coordinates of M are:
((6 - 1)/2, (3-4)/2) = (2.5, -0.5)Now point A is midpoint of A'M and point B is midpoint of MB'
Finding the coordinates using midpoint formula:
A' = ((2*6 - 2.5),(2*3 - (-0.5)) = (9.5, 6.5)B' = ((2*(-1) - 2.5), (2*(-4) - (-0.5)) = (-4.5, -7.5)Please answer i will brainliest:D

6x=-24
divide both sides by 6 to get x by itself
6x/6=-24/6
x=-4
answer: x=-4
