Which dot plot has more than one mode

The correct option is 1. Calico Crayfish dot plot has two modes.

Step-by-step explanation:

The most frequently occurring number in a set of numbers is celled mode. In other word the mode is number which has highest frequency.

In a dot plot the number of dot above a number represents its frequency.

In graph 1, the maximum number of dots is 4 at 5 and 8. Therefore this dot plot has more than one mode.

In graph 2, the maximum number of dots is 4 at 10. Therefore this dot plot has only one mode.

In graph 3, the maximum number of dots is 4 at 4. Therefore this dot plot has only one mode.

In graph 4, the maximum number of dots is 5 at 5. Therefore this dot plot has only one mode.

Therefore the correct option is 1. Calico Crayfish dot plot has two modes.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
