Answer:
Second option: 
Step-by-step explanation:
You know that "x" represents the Avery's weigth (in pounds).
Let be "y" the weight of Jada in pounds.
Since Jada weighs 18 pounds more than Avery, you can write this expression:
The weight of them together is:
Substituting, you get:
Therefore, the expression that tells how much the two of them weigh together is the one provided in the second option:
64 !! because 32 x 2 is 64
Answer:
2
Step-by-step explanation:
Let's change the base to base 10 (log10(x) = log(x)).
logb(a) = log(a)/log(b)
log3(3²) =log(3²)/log3
Knowing that log(aⁿ) = n*log(a)
log(3²)/log3 = 2*log(3)/log(3)
So, we can simply log(3)/log(3) = 1
log3(3²) = 2
Answer:

Answer:
The probability that R2 is bigger than R1 is P=0.9633.
Step-by-step explanation:
We need to compute the probability that R2 is bigger than R1:
To do this, we define a new variable Das the difference between the two resistances:
Then,
As R1 and R2 are normal random variables, the properties of D are:
Then, we can calculate the z-value for D=0
