Get rid of the decimal first.
-0.875*1000
-875/1000=-0.875
Simplify it since both denominator and numerator is divisible by 5
1/5(-875/1000)
-175/200
Still divisible by 5
1/5(-175/200)
-35/40
Keep going
-7/8
There, now it can’t be more simplified.
Answer:
1 hour = 60 minutes
20 minutes = 1/4 of 60 minutes, which means 60 minutes = 4/4
when you write ratios, the larger number goes first - 60 minutes out of 15 minutes = 4/1, so the ratio in simplest form is 4:1
hope this helped!
Z = (x - mean) / SD = (79 - 70) / 3 = 3
<span>P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135</span>
Try 21 if its wrong sorry im not very smart
Divide both sides by -2, giving you y= -1+1/5x. The slope would be 1/5
