The weights of seven frogs were studied. all the weights were muntiples of ten. the heaviest frog weighed 300 grams and the lightest weighed 100 grams. the media weight was 130 grams. the mean weight was 150 grams, and the mode weight was 110 grams. what is the only sequence of seven weights to fit this description?

The weights of the seven frogs divided by 7 gives 150. The weight we are given are: 300, 100, 130 and 110, which has the highest frequency.
To get the total number of weight, x: x/7= 150.
x =150 *7 = 1050.
300+100+130+110=640
1050 - 640=410.
410 - 110 - 130 = 170.
Thus, the last sequence for the description is 190.
The complete weights are:300, 170, 130, 130 110, 110, 100
