Suppose Madison is traveling due west for 0.5 miles and then due south for 1.2 miles.
sweet [91]

Answer:

b) 1.3 units

b) 22.61° East of North

Step-by-step explanation:

|\vec{AB}|=\sqrt{0.5^2+1.2^2}\\\Rightarrow |\vec{AB}|=\sqrt{0.25+1.44}\\\Rightarrow |\vec{AB}|=\sqrt{1.69}\\\Rightarrow |\vec{AB}|=1.3

|\vec{AB}|=1.3\ units

Magnitude of vector AB is 1.3 units

tan\theta=\frac{0.5}{1.2}\\\Rightarrow \theta=tan^{-1}\frac{0.5}{1.2}\\\Rightarrow \theta=22.61^{\circ}

The direction of vector AB is 22.61° East of North

The 2014 draft picks for the NBA basketball teams have heights that are approximately normally distributed with mean 79.1 inches
ryzh [129]

It is given that the mean is 79.1 inches and standard deviation is 3.0 inches so it follows:

\mu=79.1,\sigma=3

So the value from 75 to 81 is given by:

\begin{gathered} P(75\leq x\leq81)=P(x\leq81)-P(x\leq75) \\ =P(z\leq\frac{81-79.1}{3})-P(z\leq\frac{75-79.1}{3}) \\ =P(z\leq0.63)-P(z\leq-1.36) \end{gathered}

Use the table or a software to get the probability values and substitute to get the probability value as:

The probability is 0.6509.
