No. when plugging 4 into the equation, 0 is not the final result. instead it is 6.
square root of 2(4)+1 = square root of 9 = 3
3+3 = 6
and 6 is not 0 so x cannot = 4
The z-score counts the number of standard deviations from the mean. Then the meaning in gallons of a difference in z-score is found by multiplying the z-score difference by the value of a standard deviation.
(3 -0)*1.2 = 3.6 . . . . gallons.
The 3rd selection is appropriate.
Answer:
Step-by-step explanation:
reqd.area=area of square ABCD + area of trapezoid(or trapezium)CEFG
BE=BC+CE=16+16
CD=CG+GD=8+8
A=16×16+1/2 (16+8)×16
=256+192
=448 sq. inches.
or
reqd. area=32×16-1/2(8×16)
=512-64
=448 sq. inches.
