How to create a 2D array containing random floats between 5 and 10?

# Input
arr = np.arange(9).reshape(3,3)

# 1:
rand_arr = np.random.randint(low=5, high=10, size=(5,3)) + np.random.random((5,3))
# print(rand_arr)

# 2:
rand_arr = np.random.uniform(5,10, size=(5,3))
print(rand_arr)

# output
[[ 8.50061025  9.10531502  6.85867783]
 [ 9.76262069  9.87717411  7.13466701]
 [ 7.48966403  8.33409158  6.16808631]
 [ 7.75010551  9.94535696  5.27373226]
 [ 8.0850361   5.56165518  7.31244004]]
