Answer:
Step-by-step explanation:
a₁ = 37
a₂ = 74
Common difference d = a₂ - a₁ = 37
nth term = a₁ + (n-1)d
= 37 + (n-1)37
= 37n
Answer:
4/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (-1 -3)/(-3 -2)
=-4/-5
= 4/5
About 95% of a normal distribution lies within two standard deviations of the mean, so 5% lies without, and since the distribution is symmetric, 2.5% lies to either side. This means
