8 0

Well,

You can just add up the numbers to get 2.4.

Example:
$1.0*10^{-3}+1.4*10^{-3}=10^{-3}(1.0+1.4)=2.4*10^{-3}$

In the same way you can make a subtraction problem.

Example:
$5*10^{-3}-2.6*10^{-3}=10^{-3}(5-2.6)=2.4*10^{-3}$

Answer:

5/48, 3/16, .5, .75, 13
1/5, .35, 12/25, .5, 4/5
-3/4, -7/10, 3/40, 8/10
-.65, -3/8, 5/16, 2/4

Step-by-step explanation:

5/48 = 1.0291666666 | 3/16 = .1875 the rest is obvious
1/5 = .2 | 12/25 = .48 | 4/5 = .8
-3/4 = -.75 | -7/10 = -.7 | 3/40 = .075 | 8/10 = .8
-3/8 = -.375 | 5/16 = .3125 | 2/4 = .5

A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes: 3 4 5 2 7 1 3 7 2 6 2 1 7 3

Greeley [361]

The prime numbers on the dice are 1,2,3,5 and 7 , the theoretical probability is
$\frac{5}{8}$ , which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is $\frac{3}{4}$ , which is 75%, the difference between the experimental probability and the <span>theoretical probability is 12.5%.</span>
