7 x 13 = 91 x 4 = 364 = Area of the four rectangles.
8 x 7 = 56 x 2 = 112 = Area of the two squares.
364 + 112 = 476 cm2
Surface Area = 476 cm2
Hope this is helpful!
Answer
It would be at -4
Step-by-step explanation:
You have to look for the 8 on the graph and see what other number corresponds with it.
The '68-95-99.7 ' rule says,
-About 68% of values fall within one standard deviation of the mean.
-About 95% of the values fall within two standard deviations from the mean.
-Almost all of the values — about 99.7% — fall within three standard deviations from the mean.
Here
The length falls within one standard deviation of the mean.
Therefore, the probability
The required probability is
They are wrong. Anything to the 0 power is 1. Also, the image is unclear
Answer:
(-8,-10)
Step-by-step explanation:
we have the two equations x-2y=12 and y=3x+14.
I'm going to assume this is a system of equations and we are looking for the solution.
we can use the substitution method as y is "defined".
x-2y= 12
substitute y = 3x + 14
x-2(3x+14)=12
distribute
x - 6x -28 = 12
combine like terms
-5x - 28 = 12
add 28 to both sides
-5x = 40
divide both sides by -5
x = -8
Now we plug in the value of x into one of the equations and solve for y
y = 3x + 14
x = -8
y = 3(-8) + 14
y = -24 + 14
y = 10
the solution is (-8,-10)
