Answer:
Gracias
Step-by-step explanation:
Because it is BELOW sea level after 10 minutes, it straight away cannot be A) or B), because ascended means going up, so it has to be either C) or D).
I believe the answer is C), as the answer for D) would be -40 meters per minute, but it's still 40. I'm not sure though, so it's either C) or D).
5000
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.
Answer:
answer is option B
Step-by-step explanation:
ok the equation is 2/3 x +9 = 15
if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.
2/3x = 6
now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)
we multiply both side by reciprocal ie,
2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.
x = 6 x 3/2 = 18/2 = 9.
