Answer:
58.3% to the nearest tenth.
Step-by-step explanation:
The prime numbers from 1 to 6 are 2,3 and 5.
The probability of a prime number taken from the result of the 300 throws:
= (sum of the frequencies for 2, 3 and 5) / ( total throws)
= (60 + 55 + 60) / 300
= 0.5833 or 58.3%.

Answer: ![x+8=20](https://tex.z-dn.net/?f=x%2B8%3D20)
Step-by-step explanation:
Given
Equation is ![\frac{x}{2}+4=10](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%2B4%3D10)
Mila uses the first step as multiplication to make the coefficient of x, 1
Mila maybe have multiplied the whole equation by 2 i.e.
![\Rightarrow 2\left(\dfrac{x}{2}+4=10\right)\\\\\Rightarrow x+8=20](https://tex.z-dn.net/?f=%5CRightarrow%202%5Cleft%28%5Cdfrac%7Bx%7D%7B2%7D%2B4%3D10%5Cright%29%5C%5C%5C%5C%5CRightarrow%20x%2B8%3D20)
