Edin has £300 in his saving account his bank offers his a fixed 5% simple interest rate per annum for a period of 3 years how much interest will he have earned after 3 years ?

45

Step-by-step explanation:

The simple interest formula is

I=p×r×t

I interest earned?

P principle 300

R interest rate 0.05

T time 3years

So

I=300×0.05×3

I=45

interest will he have earned in 3 years is 45

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
