Answer:

C.  a bell-shaped curve, better known as a normal distribution

Step-by-step explanation:

We assume that 1000 adult men are selected at random in a county, their weights are measured and plotted on a histogram. In such a scenario the weight plot is expected to fit a normal distribution. The normal distribution is centered on the mean of the weights and helps determine the weight deviations from the mean. A normal distribution curve is shaped like a bell with the highest point corresponding to the mean weight.

Hello,

Answer B (2.0017868263...feet)

We must foind the intersection of the line and the parabola:

- \dfrac{4}{10} x^2+3x= \dfrac{22}{49}x+ \dfrac{818}{490}\\
...\\
196x^2-1250x+818=0\\

x= \dfrac{1250- \sqrt{921188} }{392}\approx0.7403433860\\

y=-0.4*0.74034...^2+3*0.74034...\approx2.0017868263...
