Answer:
Step-by-step explanation:
<A = 180 - (63+90)
<A = 180 - 63 - 90
<A = 180 - (63+45+<B )
<A = 180 -63 -45 -<B
The z-score tells you
the value is 0.02 standard deviations above the mean.
Well if it pumps 4 2/5 per minute that is equal to 4 4/10 in a minute or 4.4 because you multiply the top and bottom of the fraction by two. it’s still the same fraction but it is easy to convert to a decimal now. you could use this fraction but it’s much easier to use decimals. Because the first number is a decimal you should make the second one a decimal too. To do this you need to know that 1/4 of 100 is 25. so now we have these numbers and all you do now is divide 17.25 by 4.4 which could be rounded to 4 because it’s a long decimal
