State, with an explanation, whether you would expect the following data sets to be normally distributed. The weights of 200 new pickup trucks of the same make and model. A. The data set is not expected to be normally distributed. Since the trucks are all the same make and model, all of the trucks will weigh the same weight. B. The data set is not expected to be normally distributed. Due to the potential for manufacturing defects, it cannot be guaranteed that all of the trucks will weigh the same weight. C. The data set is expected to be normally distributed. Since the trucks are all the same make and model, all of the trucks will weigh the same weight. D. The data set is expected to be normally distributed. Since the trucks are all the same make and model, most of the trucks will weigh the same weight. Some trucks may weigh more or less due to manufacturing defects, making the distribution normally distributed.

Give reason. 4. In the given triangle \( \mathrm{ABC}, \mathrm{AB}=\mathrm{AC} \). Find all the three angles of the triangle.

The multiplicity of the lat (Simplify your answers.) Determine the behavior of the function at each zero. Select the correct choice below and, if ner A. The graph crosses the \( x \)-axis at \( x= \) (Type integers or decimals. Simplify your answers. Use a comma to separate answers B. The graph touches the \( x \)-axis and turns around at all zeros. C. The graph crosses the \( x \)-axis at all zeros.

6. Resuelve las siguientes ecuaciones. Incluir el procedimiento. \( \begin{array}{l}6 x-12-3 x=-8 \\ 6 x+8(2-x)=8 x+10 \\ \frac{4}{6} z-10=\frac{2}{12} z \\ \frac{8 x-4}{6}=-12 \\ \frac{3 x}{5}-\frac{2 x}{3}+\frac{1}{5}=0 \\ \frac{5 x-9}{3}+\frac{x}{2}=10\end{array} \)

(1) Last year, there were 480 blue shirts and green shirts in the school. This year, there are 498 blue shirts and green shirts. This includes a \( 2 \% \) decrease in the number of blue shirts and a \( 10 \% \) increase in the number of green shirts. How many blue shirts and green shirts were there in the school last year? Use the following two ways.
