Answer:
468
Step-by-step explanation:
Set it up like the following-
18
26
--------
108
360
--------
408
Take the right number (6) and multiply it with 18
6 x 18 = 108
Now do the same with 2, except put a 0 at the end
2 x 18 = 36
add 0
360
Add both numbers-
360 + 108 = 468
Answer:
0.5867 is the lower bound for the proportion of voters who favor the proposal.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 40
Number of voters who support the proposal, x = 29
95% Confidence interval:
Putting the values, we get:
0.5867 is the lower bound for the proportion of voters who favor the proposal.
Answer:
the angle in ascending order is 24°, 36° and 120°
Step-by-step explanation:
The largest angle of a triangle is 5 times as large as the smallest angle
The third angle is 12 degrees more than the smallest angle.
let the smallest angle be x
the largest angle is 5x
the third angle is (12+x)
the sum of angles in a triangle is 180°
x + 5x + (12+x) = 180
x+5x+ 12+x = 180
7x+12 = 180
7x = 180 -12= 168
x = 168/7 = 24°
the smallest angle is 24°
the largest angle is 5x= 5 x 24 = 120°
the third angle is 12 +x = 12+24 = 36°
x = 9
The sides on the left are proportional and can be used to find the sides on the right.
Since 72/8=9, 56/8 must equal 3x-20
the mean is 50.5, but rounded it's 51.
