We will verify each options

option-A:

\sqrt{121}

we can factor it

\sqrt{121}=\sqrt{11*11}

\sqrt{121}=\sqrt{11^2}

\sqrt{121}=11

so, this is not irrational.........Answer

option-B:

\sqrt{65}

Since, it can not be factored

so, this is irrational.........................Answer

option-C:

\sqrt{36}

we can factor it

\sqrt{36}=\sqrt{6*6}

\sqrt{36}=\sqrt{6^2}

\sqrt{36}=6

so, this is not irrational.........Answer

option-D:

\sqrt{64}

we can factor it

\sqrt{64}=\sqrt{8*8}

\sqrt{64}=\sqrt{8^2}

\sqrt{64}=8

so, this is not irrational.........Answer

The mean number of words per minute (WPM) typed by a speed typist is 149 with a standard deviation of 14 WPM. What is the probab
Troyanec [42]

Answer:

78.81%

Step-by-step explanation:

We are given;

Population mean; μ = 149

Sample mean; x¯ = 147.8

Sample size; n = 88

standard deviation; σ = 14

Z-score is;

z = (x¯ - μ)/(σ/√n)

Plugging in the relevant values;

z = (147.8 - 149)/(14/√88)

z = -0.804

From z-distribution table attached, we have; p = 0.21186

P(X > 147.8) = 1 - 0.21186 = 0.78814

In percentage gives; p = 78.81%
