Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp
mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P)  =  $1000 .

interest rate (R)  =  7.5 % .

Time period (T) =  1  year .

\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}

        = \frac{1000 * 7.5 * 1}{100}

         = $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

S . I =  \frac{4000 * 7.75 * 1}{100}

      = $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

                                                       = $ 385

Given:  

Number of plants with white flowers=769

Number of plants with purple flowers= 326

To Find:

The probability that a plant had white flowers is=?

Solution:

Total number of flowers plants = Number of plants with white flower + Number of plants with purple flowers

Total number of flowers plants = 769+ 326

Total number of flowers plants = 1095

Probability that the plant had white flowers  = \frac{769}{1095}

Probability that the plant had white flowers  =0.70

Probability that the plant had purple flowers  = \frac{326}{1095}

Probability that the plant had purple flowers  = 0.29
