Step-by-step explanation:
given a normal distribution with the given parameters the probability (= the % of the area of the distribution curve) for a number to be between 203 and 1803 is
0.9987
so, 99.87% of all numbers are expected to be in that range.
for 350,000 numbers that means
350,000×0.9987 = 349,545 numbers are expected to be between 203 and 1803.
Answer:
yous should multiply it by 3.6;
0.12*3.6=0.432 km/h
It is a real number.
A real number is a combination of rational (usually negative) and irrational numbers.
A natural number is a positive integer.
But since -145 is a negative number it can't be a natural number. Making it a real number.
Correct me if I'm wrong.

Step-by-step explanation:
If the growth is 7 feet in 2 weeks and the rate is constant, then it will be half that in one week, or 3.5 feet per week. At week 3, it will be 3.5 feet more than at week 2. The table below shows this progression.
The point (0, 0) means there was no measurable growth when time was starting to be measured (at week 0).
21²=21×21
21×21=441
2,870+441=3,221
