Answer: Volume of sugar cube=2.20 cm³
Density of sugar cube = 1.60 g/cm³.
The sugar cube will sink.
Step-by-step explanation:
Given : Mass of cube = 3.48 g
Also, dimension of sugar cube :
height = length = width = 1.3 cm
Since , the volume of cube = (side)³
Volume of sugar cube=(1.3) ³= 2.197 ≈ 2.20 cm³
Also, Density =
⇒ Density of sugar cube =
∴ Density of sugar cube = 1.60 g/cm³.
It is known that the density of water is 1 g/cm³.
Here , density of sugar cube > density of water
⇒ The sugar cube will sink .

Answer:
P(X < 7) = 0.76
Step-by-step explanation:
Counting properly from the diagram attached to the question,
number of trials it took her to make less than 7 shots(i.e. 0 to 6 shots) = 38
The total number of trials she made = 50
Probability that it takes fewer than 7 shots to get her first successful shot, P(X < 7) = (number of trials it took to make less than 7 shots)/(Total number of trials)
P(X < 7) = 38/50
P(X < 7) = 0.76
