The scientific notation of 6.3 is written as 6.3 × 10^0; option A
<h3>Scientific notation</h3>
- The decimal points should be moved between the first digit and the next digit.
- When moving decimal point to the left in scientific notation; it is negative, that is, -
- When moving decimal point to the right in scientific notation; it is positive, that is, +
Therefore, since there are only two significant number in 6.3, the decimal point can not be moved.

The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
Answer:
(a) 3.75
(b) 2.00083
(c) 0.4898
Step-by-step explanation:
It is provided that X has a continuous uniform distribution over the interval [1.3, 6.2].
(a)
Compute the mean of X as follows:
(b)
Compute the variance of X as follows:
(c)
Compute the value of P(X < 3.7) as follows:
![P(X < 3.7)=\int\limits^{3.7}_{1.3}{\frac{1}{6.2-1.3}}\, dx\\\\=\frac{1}{4.9}\times [x]^{3.7}_{1.3}\\\\=\frac{3.7-1.3}{4.9}\\\\\approx 0.4898](https://tex.z-dn.net/?f=P%28X%20%3C%203.7%29%3D%5Cint%5Climits%5E%7B3.7%7D_%7B1.3%7D%7B%5Cfrac%7B1%7D%7B6.2-1.3%7D%7D%5C%2C%20dx%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B4.9%7D%5Ctimes%20%5Bx%5D%5E%7B3.7%7D_%7B1.3%7D%5C%5C%5C%5C%3D%5Cfrac%7B3.7-1.3%7D%7B4.9%7D%5C%5C%5C%5C%5Capprox%200.4898)
Thus, the value of P(X < 3.7) is 0.4898.
This is a division problem.
20 divided by 1 1/4
20/(1 1/4) = 20/(5/4) = 20/1 * 4/5 = 80/5 = 16
There are 16 cans.
