Answer:
x = 10 degrees
Step-by-step explanation:
angle EAB is a right triangle, which means it measures 90 degrees. it is also given as 5x + 4x
so,
5x + 4x = 90
9x = 90
x = 90/9 = <u>10</u>
0.55+0.54=1.08 and 0.54 divided by 2 is 0.28 which you add 1.08+0.27 which is 1.35. Your answer is 1.35
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 )
The number is -240 because -240 divided by 4 is -60
Here’s the answer and work
