idk
Step-by-step explanation:
Answer:
y=5/2x+2
Step-by-step explanation:
rearrage equation: y=5/2x-7
new slope is same: y=5/2x+b
substitue point (-2,-3):
-3=5/2(-2)+b
-3=-5+b
-3+5=b
2=b
the correct answer is C
make the mixed number to an improper fraction:
7/2 × 4/7
cross simplify and you get 1/1 × 2/1
so your final answer is: 2
Answer:
The standard deviation reduces when sample size (n) increases
Step-by-step explanation:
From the above information given, we have that mean = 75.5
Standard deviation = 3.5
But Standard deviation = √summation (x-u)/n
This simply implies that when sample (n) is increased there would be a reduction in the standard deviate.
it would be A or D for the math of d=-2
