A deposite of 800 was made into a savings account and has grown to 1000 in 3 years the growth in value was via simple interest calculate on the basis of the initial deposite calculate the rate of interest

the interest rate is 8.3%

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount of money deposited.

P represents the principal or amount of money deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 800

R = 1000 - 800 = $200

T = 3 years

Therefore,

200 = (800 × R × 3)/100

200 = 24R

R = 200/24

R = 8.3%

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
