Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are normally distributed, with a mean of 5.2 millimeters (mm) and a standard deviation of 0.9 mm. What's the probability that an ancient prehistoric Native American pot shard discovered in this area has thickness measurement thinner than 3.4 ? Find the answer without using the normalcdf(...) function. (Write the answer in decimals)

SELF-ASSESSMENT 1 Idon't understand yet 21 can do it with help. 3 I can do it on my own. Find the value of \( x \) so that the function has the given value. \( \begin{array}{ll}\text { 5. } f(x)=6 x+9 ; f(x)=21 & \text { 6, } g(x)=-\frac{1}{2} x+3 ; 8(x)=-1\end{array} \)

\( \begin{array}{ll}\text { 4) } \frac{x-1}{x+4}-\frac{x+2}{x-1}= \\ & \text { 4) } \frac{x-3}{x+3}-\frac{x-1}{x+5}=\end{array} \)

(b) The increase in price of a flight to Mumbai was \( £ 48 \) Work out the price of a flight to Mumbai after the increase.

\( 1 \leftarrow \frac { 1 } { 4 } \)

\( \sqrt {3}.(\sqrt {2}+\sqrt {15})-\sqrt {6} \)
