Firstly multiply 3x by 6 which gives you 18x
then multiply 6 and -7 which is -42. The final result is 18x-42.
Answer:
3.25 in one hour
Step-by-step explanation:
6.5 ÷ 2 = 3.25

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.
In this case, you are asked to bring the area with m2 unit but the length(120yd) and width(50yd) are in yd. Then, you need to convert the unit into m2. The formula of rectangle area should be length * width.
So, the equation should be:
area = length * width= (120yd * 91.44cm/yd * 1m/100cm) * (50yd * 91.44cm/yd * 1m/100cm) = 5016.76 m2
