So if QR and PQ are the same ( which they are bc the angles and other sides are the same) 3n-1= 5n-7 so -1= 2n -7 so 6 = 2n so n = 3 then QR is 5n -7 so 5 x 3 is 15-7 is 8 so the answer is 8. Hope this helps :)
Answer:#4 is 3L Starwberry juice and 6L orange Jucie.
Step-by-step explanation:
I) 156 degrees
The exterior angle is 180-156
=24
The number of sides=

The number of sides= 15 sides
ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=

= 20 sides

I think the answer is Letter C - 0.032.
Given: p - 0.1; n - 90
Required: standard deviation of the sample proportion
Solution: To get the standard deviation of the sample proportion, we will use this formula - std = √p (1 - p) / n Replace the variables with the given values, then simplify.
std = √0.1 (1 - 0.1) / 90
std = √0.09 / 90
std = √0.001
std = 0.032
