Answer:
-13 or 13
Step-by-step explanation:
Since we are looking for the square root of 169, we realize that 13 multiplied by itself equals 169. Negative 13 does the same, so it is the answer.
From this we know that x = -8
So all we need to do is plug -8 into the equation everywhere there is an x
So y = -4 * -8 + 3
y = 32 + 3
So y is equal to 35, and since y is the output, the output is 35
Answer:
0.216
Step-by-step explanation:
If the probability of green, P(green) is 40%, the probability of red, P(red) is 60%.
The probability of a light being red is not affected by the colour of the previous light, so at each of the 3 lights, the probability of red is always 60%.
To find the probability that all three lights will be red, multiply the three probabilities together. (Convert them to decimals first).
0.6 x 0.6 x 0.6 = 0.216
2(x+4)^2+4
That is the answer!
The opposite of -2/3 is 2/3
