Just gonna give you the answer:
The constant variation is 1/2
Answer:
0.125
Step-by-step explanation:
<u>Smaller Wheel</u>
Total Number of Equal Sectors = 8
The number of Red sectors =3
The probability of obtaining red on the smaller wheel 
<u>Larger Wheel</u>
Total Number of Equal Sectors = 12
The number of Red sectors =4
The probability of obtaining red on the larger wheel 
Assuming that the wheels are independent and each outcome is equally likely, the probability that we get red on both wheels

The probability is: 0.125
Answer:
3.5
Step-by-step explanation:
Given : the hydronium ion concentration is
in orange juice
To Find: what is the pH?
Solution :
Definition of pH : pH is the negative log of the molar hydrogen ion concentration
Formula of pH : - log [H+]
Since we are given H+ = 
So, substituting this value in formula :
![pH = - log [3.4*10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A10%5E%7B-4%7D%5D)
![pH = - log [3.4*0.0001]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A0.0001%5D)
![pH = - log [0.00034]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B0.00034%5D)

pH = 3.468≈3.5
Thus the pH is 3.5
Answer:
Step-by-step explanation:
isosceles trapezoid = congruent sides in pairs and the same for the angles
<h2><u><em>
angle 1 = 32°</em></u></h2><h2><u><em>
angles 2 & 3 = 148°</em></u></h2>
the sum of the interior angles is 360°
so angle 1 = 32°
angles 2 and 3
(360 - 32 - 32) :2 = 148°
check
32 + 32 + 148 + 148 = 360°
the answer is good
