Answer:
60
Step-by-step explanation:
Total degree of triangle interior angles is 180
So x+2x+3x=180
6x=180
x=30
Measurement of angle C is 2x which is 60 degree
It equals 256 fluid ounces
Answer:

Step-by-step explanation:
a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.
-we know that the value of probabilities are in the range [0,1]:
-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5
b. The null hypothesis usually represents the true value parameter under study.
-As stated above, the true value of the parameter is 38%;
-Hence, the null hypothesis is 
#Alternative hypothesis is the control value, given the value of the parameter p=0.38, the alternative hypothesis is that p has a different value other than 0.39:

</span><span>The probability of an event is a chance of it happening. It is calculated as;
Probability =(fouvarable outcome)/(total outcome)
Since we are finding the probability of no girl will be chosen, it is like finding the probability of choosing 3 boys.
The probability of choosing the first boy =4/12
The probability of choosing the second boy =3/11
The probability of choosing the third boy =2/10
The probability of choosing the 3 boys will be,
=4/12×3/11×2/10
=24/1320
=1/55
