Answer:
Step-by-step explanation:
From the question we are told that:
Sample size 
Mean 
Standard deviation 
Generally 99\% confidence from table is mathematically given by
Generally the equation for 99\% confidence level (CI) is mathematically given by
If x = -4
f(x) = (-4)^2 = 16
if x = 4
f(x) = √4 = 2
hope it helps
The range is the difference betweem the largest and smallest NUMBERS in the whole piece of data. The IQR is the difference between the largest and smallest QUARTILES. For example, if you had the data 1,2,3,4,5: 5-1=4 would be the range and...(4-2)=2 would be the IQR. Hope this helped! :)
Answer:
12°, 78°, 90°
Step-by-step explanation:
let the third angle be x then the second angle is 7x - 6
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 7x - 6 + 90 = 180, that is
8x + 84 = 180 ( subtract 84 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus second angle = 12° and third = 7(12) - 6 = 84 - 6 = 78°
The 3 angles are 12°, 78° and 90°
The next term in the sequence is double the previous term . so it would be the 3rd option (48,96,192)
