I think its c. Can't really see the others.
Hope this helps :)

The following figures are parallelograms:
Figure A
Figure B
Figure E
==================================================
Explanation:
If the diagonals of the quadrilateral are the same length (aka congruent), then we can prove that we have the opposite sides parallel. That would conclude in the figure being a parallelogram. Therefore, choice A is a parallelogram because of this fact. Choice C is not a parallelogram because of this.
Also, recall that parallelograms have their opposite sides being the same length. Think of a rectangle, but we can slant the sides as figure B shows. Figure B is a parallelogram due to the opposite sides being the same length. More specifically, it's a rhombus (because all four sides are the same). Any rhombus is a parallelogram, but not the other way around.
One last useful property we'll use is the fact that adjacent angles of a parallelogram are supplementary. This means the angles add to 180. In figure D, the adjacent angles add to 74+105 = 179, which isn't 180. So we rule out choice D. Choice E works though because 55+125 = 180.
Answer:
residual cost = $24.57
Step-by-step explanation:
The residual is the difference between the observed value of y and the predicted value of y. The least square regression equation was used to predict cost in dollars per barrel of jet fuel from the cost , in dollars ,per barrel of crude oil. The residual value is the difference between the observed or measured value and the predicted value of the regression model . The predicted value is gotten from the regression equation.
y = 2 + 6/7 x
where
x = cost of a barrel of crude oil
x = $60
y = 2 + 6/7 × 60
y = 2 + 360/7
y = 2 + 51.4285714286
y = 53.4285714286
y = $53. 43
predicted cost = $53. 43
Measured cost = $78
residual = observed value - predicted value
residual = 78 - 53.43
residual cost = $24.57
Answer:
2x - 3 = 1
Step-by-step explanation:
![{7}^{2x - 3} = {7}^{1} \\ \\ \because \: bases \: are \: equal \: on \: both \: sides \\ \implies \: exponents \: will \: also \: be \: equal \\ \\ \implies \: 2x - 3 = 1](https://tex.z-dn.net/?f=%20%7B7%7D%5E%7B2x%20-%203%7D%20%20%3D%20%20%7B7%7D%5E%7B1%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cbecause%20%5C%3A%20bases%20%5C%3A%20are%20%5C%3A%20equal%20%5C%3A%20on%20%5C%3A%20both%20%5C%3A%20sides%20%5C%5C%20%20%5Cimplies%20%5C%3A%20exponents%20%5C%3A%20will%20%5C%3A%20also%20%5C%3A%20be%20%5C%3A%20equal%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%202x%20-%203%20%3D%201)
