Answer:
-13.315° F
Step-by-step explanation:
Number of years from 2019 to 2050 is 2050 - 2019 = 31 years
Increase in temperature per year = 0.135
Increase in temperature for 31 years = 0.135*31 = 4.185
Average temperature in 2050 = -17.5 + 4.185 = -13.315° F
Answer:

Step-by-step explanation:
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
Answer:
Infinite solutions.
Step-by-step explanation:
Let's solve your system by substitution.
3y=9x+15;3x−y=−5
Rewrite equations:
3x−y=−5;3y=9x+15
Step: Solve 3x−y=−5 for y:
3x−y=−5
3x−y+−3x=−5+−3x(Add -3x to both sides)
−y=−3x−5
−y −1 −1=−3x−5
(Divide both sides by -1)
y=3x+5
Step: Substitute 3x+5 for y in 3y=9x+15:
3y=9x+15
3(3x+5)=9x+15
9x+15=9x+15(Simplify both sides of the equation)
9x+15+−9x=9x+15+−9x(Add -9x to both sides)
15=15
15+−15=15+−15(Add -15 to both sides)
0=0
