Answer:
Total water consumption by Jeffery and Amy in 2 days is 2.8125 gallons
Step-by-step explanation:
Amount of water Jefferey Drinks each day = 90 ounces
So, the amount of water Jeffery drinks in 2 days = 90 x 2 = 180 ounces
Similarly, water required by Amy each day = 90 ounces
So, the amount of water Amy drinks in 2 days = 90 x 2 = 180 ounces
Total water consumption by Jeffery and Amy in 2 days
=180 ounces + 180 ounces
= 360 ounces
Now, <u>1 ounce = 0.0078125 gallons</u>
So, 360 ounces = (360 x 0.0078125) gallons
= 2.8125 gallons
Hence, Total water consumption by Jeffery and Amy in 2 days is 2.8125 gallons
Given that
P(z/2)=89.48%
the value that corresponds to this will be given as follows:
the z-value that corresponds to 89.48% in the z-table is:
1.25
thus
z/2=1.25
hence
z=1.25*2
z=2.50
