The mean is 15.25
12 + 24 + 8 + 17 = 61
Divide that by the total number of variables (4) to get 15.25.
Answer:
Step-by-step explanation:
If she was given a discount of 12% then the amount to be paid becomes I=P×R×T/100
I=400000×12×20/100
I=960000
Amount to be paid =I +P= 960000+400000=1360000
To liquidate this amount in 20 years therefore will be A÷20
1360000÷20
=68000 yearly
48.9 - 24.8 = 24.1
So, Emily's cocker spaniel weighs 24.1 pounds.
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
