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 ------
Answer:
11 Students
Step-by-step explanation:
It is hard to explain in my opinion but I can try. For the stem column you, basically factor out the first digit of the number. Then the leaf column you, put the second digit of each number in your data set.
Answer:
l : b = 6 : 5
Step-by-step explanation:
let's assume lenght of each congruent rectangle be x
now,
Lenght of the larger rectangle =
=》3 × lenght of smaller rectangle = 3x
but it is also equal to
=》4 × width of each smaller rectangles ( b )
so, we get :-
=》4 × b = 3x
=》b = 3x / 4
so, we get width of smaller rectangle =
now, width of larger rectangle =
=》lenght of smaller rectangle + (2 × width of smaller rectangle)
=》
=》
=》
=》
now, length of larger rectangle = 3x
width of larger rectangle = 5x/2
so l : w :-
=》
=》
=》
so, required ratio of l : b = 6 : 5
