Answer:
CI = ( 36,6 ; 41,4 )
Step-by-step explanation:
CI = 99,9 % α = 0,1 % α = 0,001
We find z scre for α = 0,001 in z -table
z(s) = - 3,08
CI = μ₀ ± MOE where μ₀ = 39 min and MOE = z(s) * σ/√n
CI = 39 ± 3,08 * 4,8 / √37
CI = 39 ± 2,4315
CI = ( 36,6 ; 41,4 )

d
Answer:
56
Step-by-step explanation:
there are 56 boxes in yellow with each box = 1cm^2
perpendicular means negative reciprocal so it would be -1/3
Answer:
(x-2 )( x + 1) = (-2 - c)
Step-by-step explanation:
C= - 1 = -x
We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.
To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.
We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.
So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;
Balance of each 1000 would look like
2/3y + x + c
= c + xy - y1/3
to show smaller amounts for the last 2 debits.
