The rate of interest at which Dylan invested is 3.09%.
The practice of adding interest to the principal of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It happens when interest is reinvested, added to the collateral for the loan rather than paid out, or when the borrower is forced to pay it, resulting in interest being created on the principal amount plus any accumulated interest the following period. Compound interest is a prominent concept in finance and economics.
Compound interest allows interest to accumulate over time, in contrast to simple interest, which does not compound because past interest is not returned to the principle for the present period.
principal =360
time =5 years
n=5×4=20 (compounded quarterly)
Amount = 420
Now: 420 = 360(1+r)²⁰
solving for r we get:
r= 0.007737
required rate percent = 0.007737×4 = 0.00193 × 100 = 3.09%
hence the simple annual interest rate is obtained by multiplying the interest per period by the total number of periods in a year is 3.09%.

Answer:
The appropriate test for the investigation is;
E. A chi-square test of independence
Step-by-step explanation:
The chi-square test for independence is for the analysis of two categories from within a population to evaluate the existence of association among the different categories within the two variables
The chi-square test for independence is used for the analysis of contingency (frequency) table
Therefore, the appropriate test for the investigation in finding out (1) the textbook preference and (2) the class level of the associated student is the chi-square test of independence
Answer:
let Φ be the central angle of the arc
pi*2r = 20
r = 10/pi
arc length= 2pi*r*(Φ/360°)
4 = 2pi*r*(Φ/360°)
Φ=2/10 * 360° =72° degree
