Answer:
Step-by-step explanation:
j=+
We move all terms to the left:
j-(+)=0
We add all the numbers together, and all the variables
j-0=0
We add all the numbers together, and all the variables
j=0
Y=2x+1 I think this is correct but I don’t know how to do equations very well

Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
