Answer:
A. 0.020
Step-by-step explanation:
we calculate the standard error of the sample mean with the formula,
,
with E= standard error of the sample mean
s= standard deviation
n= sample
So,
s= 0.2
n= 100
ITS 1 AND 5! IM SO SHMART
In general, to find the surface area of a prism (a shape with 2 bases) is
Area of Base*2 + Lateral Area (Lateral area = Perimeter of bases * height)
#9 Area of base= 2×1÷2=1 *2=2
Lateral area= 2+1+2.2=5.2 5.2*3=15.6
Answer=17.6
#10 Area of Base= 120*2=240
Lateral Area=500
Answer=740
#11
Area of base=8*2=16
Lateral Area= 41.4
Answer=57.4
Answer:
C. 4
Step-by-step explanation:
To solve, set each parenthesis equal to the opposite side (0 in this case).
(x - 4)(x - 4) = 0
x - 4 = 0
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:
x - 4 (+4) = 0 (+4)
x = 0 + 4
x = 4
Do the same for the other parenthesis:
x - 4 = 0
x - 4 (+4) = 0 (+4)
x = 0 + 4
x = 4
C. 4 is your answer.
