Express the indicated degree of likelihood as a probability value “there is a 40% chance of rain tomorrow”
Bad White [126]

Answer:

The probability of rain is 0.4.

Step-by-step explanation:

The given statement is “there is a 40% chance of rain tomorrow”.

There is a 40% chance of rain tomorrow, it means out of 100 the chances of rain is 40.

\text{Probability}=\frac{\text{Required Possibilities}}{\text{Total possibilities}}

\text{Probability}=\frac{40}{100}

\text{Probability}=0.4

Therefore the probability of rain is 0.4.

Answer:

The simplest radical form is 9\sqrt{5} ⇒ (c)

Step-by-step explanation:

To simplify any square root;

  • Factorize the number under the root using prime numbers
  • Take out the root any number repeated twice as one number

<em><u /></em>

<em><u>Examples:</u></em>

1. Simplify \sqrt{8}

factorize 8 using prime numbers

8 = 2 × 2 × 2, then \sqrt{8}=\sqrt{(2)(2)(2)}

Take two of 2 out the root, then \sqrt{8}=2\sqrt{2}

2. Simplify \sqrt{18}

factorize 18 using prime numbers

18 = 2 × 3 × 3, then \sqrt{18}=\sqrt{(2)(3)(3)}

Take the two 3 out the root, then \sqrt{18}=3\sqrt{2}

Let us simplify 3\sqrt{45}

∵ 45 = 3 × 3 × 5

∴ 3\sqrt{45}=3\sqrt{(3)(3)(5)}

→ Take the two 3 out by one 3

∴  3\sqrt{45}=3(3)\sqrt{5}

→ Multiply the numbers out the root

∴ 3\sqrt{45}=9\sqrt{5}

∴ The simplest radical form is 9\sqrt{5}
