Answer:
112 ounces
Step-by-step explanation:
Clay weighs 9 times as much as his baby sister .
Clay weighs 63 pounds.
His baby sister weigh 63/9.
His baby sister weighs 7 pounds.
But to be converted to ounce.
1 pound = 16 ounces
7 pounds = 7*16 ounces
7 pounds = 112 ounces
I believe the range is the middle number so start from 63 then 46 then 53 then go back and forth until you get the middle number now after you get the middle number for the IQR add up both sides of the middle and / by the all the number on the left and right of the middle number
Answer:
t=0.64
Step-by-step explanation:
h = -16t^2 +4t +4
We want h =0 since it is hitting the ground
0 = -16t^2 +4t +4
Using the quadratic formula
a = -16 b = 4 c=4
-b ± sqrt( b^2 -4ac)
----------------------------
2a
-4 ± sqrt( 4^2 -4(-16)4)
----------------------------
2(-16)
-4 ± sqrt( 16+ 256)
----------------------------
-32
-4 ± sqrt( 272)
----------------------------
-32
-4 ± sqrt( 16*17)
----------------------------
-32
-4 ± sqrt( 16) sqrt(17)
----------------------------
-32
-4 ± 4 sqrt(17)
----------------------------
-32
Divide by -4
1 ± sqrt(17)
----------------------------

To the nearest hundredth
t=-0.39
t=0.64
Since time cannot be negative
t=0.64
