Answer:
98% Confidencce Interval is ( 3030.6, 7467.4 )
Step-by-step explanation:
Given that:
Sample size
71
Sample size
31
Sample mean
41628
Sample mean
36,379
Population standard deviation
= 4934
Population standard deviation
4180
At 98% confidence interval level, the level of significcance = 1 - 0.98 = 0.02
Critical value at 
The Margin of Error = 
= 
= 
= 
= 2218.40
The Lower limit = 
= ( 41628 - 36379 ) - ( 2218.40)
= 5249 - 2218.40
= 3030.6
The upper limit = 
= ( 41628 - 36379 ) + ( 2218.40)
= 5249 + 2218.40
= 7467.4
∴ 98% Confidencce Interval is ( 3030.6, 7467.4 )

Answer:
2623.6144m²
Step-by-step explanation:
Total Surface Area of a Square Pyramid
a * (a + √(a² + 4h²))
where,
a = area of base
h = height
Using the formula above
a * (a + √(a² + 4h²))
data given :
a = 36
h = 4
a * (a + √(a² + 4h²))
T.S.A. = a * (a + √(a² + 4h²))
Inputting values
T.S.A. = 36 * (36 + √(36² + 4 * 4²))
T.S.A. = 36 * (36 + √(36² + 4 * 16))
T.S.A. = 36 * (36 + √(36² + 64))
T.S.A. = 36 * (36 + √(1296 + 64))
T.S.A. = 36 * (36 + √(1360))
T.S.A. = 36 * (36 + 36.87817782917154)
T.S.A. = 36 * (72.87817782917154)
T.S.A. = 36 * 72.8782
T.S.A. = 2623.614401850175
Therefore Total Surface Area (T.S.A.) is 2623.6144m²
Answer:
A. Positive Exponent
B. Negative Exponent
C. Rational Exponent
Step-by-step explanation:
» Any fraction is a rational exponent.
» If n is not zero, it can be negative or positive value. Then the exponent can be negative or positive.
