       This was a tricky question for me to answer, but I believe that the false statement is the 3rd option: Some natural numbers are not integers. I think that all natural numbers are integers because integers include positive AND negative numbers. All positive, whole numbers are natural numbers and integers can be positive, whole numbers. Integers cannot be fractions in their most simplified form.

A fire department in a rural county reports that its response time to fires is approximatelyNormally distributed with a mean of
____ [38]

Answer:

Option C) 0.25

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 22 minutes

Standard Deviation, σ = 11.9 minutes

We are given that the distribution of  response time is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(response times is over 30 minutes)

P(x > 30)

P( x > 30) = P( z > \displaystyle\frac{30 - 22}{11.9}) = P(z > 0.6722)

= 1 - P(z \leq 0.6722)

Calculation the value from standard normal z table, we have,  

P(x > 30) = 1 - 0.749= 0.251 = 25.1\%

Thus, the correct answer is

Option C) 0.25

There are values of t so that sin t=.35 and cos t=.6
NISA [10]

Recall the fundamental rule of trig:

\sin^2(x)+\cos^2(x)=1 \quad\forall x \in \mathbb{R}

So, there exists an angle t such that

(0.6,0.35)=(\sin(t),\cos(t))

if and only if

\sin^2(t)+\cos^2(t)=0.6^2+0.35^2=1

Working out the numbers, we get

0.6^2+0.35^2=0.36+0.1225=0.4825\neq 1

So, there doesn't exist a number t such that

(0.6,0.35)=(\sin(t),\cos(t))
