Which equation represents the line that passes through (0,8)and(2,0)
Lelu [443]
The answer is C.

y= -4x + 8
You can plug in your coordinates.


For (0,8), plug in the x and y values.
8 = -4(0) +8
8 = 0+8
8=8 so, this works

For (2,0) plug in your coordinates.
y = -4x + 8
0 = -4(2) + 8
0 = -8 + 8
0=0

If both coordinates work for the equation, then they pass through that line.

The sat scores have an average of 1200 with a standard deviation of 120. a sample of 36 scores is selected. what is the probabil
Naya [18.7K]
We first standardise \bar{x}:
P(1224 > \bar{x})=P(\frac{1224-1200}{\frac{120}{ \sqrt{36} }}>\frac{\bar{x}-1200}{\frac{120}{\sqrt{36}}})
which reduces to finding P(Z > 1.2) = 0.115

How to simplify 6 to the power of -1 over -8 to the power of 0
neonofarm [45]

Answer:

\frac{1}{6}

-8 to the power of 0 = 1

(Anything to the power of 0 = 1)

and 6 to the power of -1 = 1/6

( Any number to the power of a negative number will become a fraction)

Example.

5^{ - 3}  =  \frac{1}{5^{3} }

So is will be 1/6 over 1

Which gives you your final answer.
