Answer:
132ft²
Step-by-step explanation:
area of a parallelogram = base length × height
base length = 11 ft and height = 12ft
so area = 11 × 12 = 132ft²
Answer:
CD=10.15m
Step-by-step explanation:
<u>Find the distance of BC.</u>
Tan(40)=55/BC
BC=65.55m
<u>Find the distance of BD.</u>
Tan(36)=55/BD
BD=75.70m
<u>Use BC and BD to find CD</u>
BD-BC=CD
75.70-65.55=CD
CD=10.15m
Answer:
Hello your question is incomplete attached below is the complete question
answer : 1596 ± 2.861
------ ( A )
Step-by-step explanation:
I will use excel function to resolve this question
<u>Determine the 99% confidence of interval for the difference in mean number of steps by all people</u>
∝ = 0.01
critical value ( t ) = 2.861 ( = TINV ( 0.01, 19 )
Given that :
S1 = 1580
S2 = 2350
n1 = 20
n2 = 20
Difference in mean = x1 - x2 = 1596
Margin of Error = t *
∴ 99% confidence of interval
= 1596 ± 2.861
------
