Sixty photos taken at a photo shoot are in black and white. If this represents 15 percent of the total number of photos taken, w
Art [367]

Answer:

D. 15×4/100×4 = 60/400

Step-by-step explanation:

First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.

Which graph represents the solution to the given system? y = –2x + 5 and y = 3x – 2
DaniilM [7]
Y = -2x + 5        y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2             Subtract 3x from both sides
-5x + 5 = -2                  Subtract 5 from both sides
-5x = -7                        Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)

How to solve 2X^2+Y^2 = X^2-Y^2
arlik [135]
   
2x^2+y^2 = x^2-y^2\\\\
2x^2 - x^2 + y^2 + y^2 = 0\\\\
x^2 + 2y^2=0\\\\
x^2 = 0~~~\Longrightarrow~~~\boxed{x=0}\\\\
2y^2 = 0~~~\Longrightarrow~~~y^2 = 0~~~\Longrightarrow~~~\boxed{y=0}\\\\

Arrange the graphs in descending order (from highest to lowest) based on the values of their correlation coefficients.
Scrat [10]
Basically, the closer they fit to the imaginary line of best fit, the higher they are

the closer the dots are to the imaginary line, te higher the number

D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers
