First, let's determine how many standard deviations from the mean the value
(163+1) = 164 is:
(164 - 125)/15 = 39/15 = 2.6
Now using a standard normal table, look up 2.6 to determine the percentage of points that would be that far from the mean. I find a value of 0.49534. Note that is is a half value. So the percentage that will be higher than that will be 0.5 - 0.49534= 0.00466
Now multiply by the number of points overall, getting
0.00466 * 1000000 = 4660
So there will be approximately 5000 pixels brighter than 163 gray levels.
Building an expression, it is found that the value of the number is given by:
x = 3/50.
<h3>What is the value of the number?</h3>
We have to look at the text step by step, to build an expression involving an equality, and then solve it to find the value of the number.
We have that <u>negative one times the sum of twice of a number x and 3</u> is given by:
-1(2x + 3) = -2x - 3.
This is equals to two times the difference of 24 times the number and 3, hence:
-2x - 3 = 2(24x - 3)
48x - 6 = -2x - 3
50x = 3.
x = 3/50.

Answer:
2nd, 4th and 5th
Step-by-step explanation:
remember :
+- = -
-+ = -
-- = +
++ = +
so, the first option has all signs of all terms as +. that is wrong, as we have -1 1/5
also the third option turns all signs to +. and is therefore wrong.
the second option makes the signs +, + and -. that is correct (like the original expression). as +- = -
the fourth option is just removing the brackets, which did not change anything about the signs, as there was a + in front of the original brackets. so, it is still the correct +, + and -.
the fifth option has the first two terms with -- signs, which makes them both +.
and the third one is +-, so it is -.
so, we end up again with the correct +, + and - signs.
