Answer:
x = 39.1
Step-by-step explanation:
mean = average off all the numbers =
sum of the numbers / amount of numbers.
35 = sum of the #'s / # of #'s
35 = 100.9 + x / 4
35 × 4 = 100.9 + x / 4 × 4
140 = 100.9 + x
140 – 100.9 = 100.9 + x – 100.9
39.1 = x
x = 39.1

Distribution Formula
Answer: <em>here are the graphs. the one with the sloped line is </em>5x - 3y ≤ -15.<em> the one with the straight line is </em>y ≥ 4.
A)
Accurate = close to the 'true' value, and 9.998 is close to 10. Imagine a scale that has the zero point wrong as says 8.998, it would not be accurate, but still precise (several digits known)
Precise = several digits known. I would say to know it until grams is quite a good precision (the 9.998 has 4 digits)
