tatyana61 [14]

Answer:

$13$

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$

Goshia [24]

Answer:

The correct answer is

d. Sampling Interval = Population size ÷ Sample size.

Step-by-step explanation:

Thus,

Sampling Interval = Population size ÷ Sample size.
