Answer: The required probability is 2.167.

Step-by-step explanation:

Since we have given that

It is a uniform distribution between 46 minutes and 73 minutes.

She finishes within 58.5 minutes.

So, the general probability is :

\dfrac{58.5}{b-a}\\\\here,\\\\a=46\\\\b=73

So, the probability would be

\dfrac{58.5}{73-46}=\dfrac{58.5}{27}=2.167

Hence, the required probability is 2.167.

So,

Given

Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees

So, total 7*10^5 trees were planted.

A freezer can be bought on hire purchase by making a desposiy of 15% of the cash price which is $2975 the interest which is 20%
Liono4ka [1.6K]

Answer: See explanation

Step-by-step explanation:

a. The deposit

= 15% × $2975

= 15/100 × $2975

= 0.15 × $2975

= $446.25

b. The hire purchase price

Outstanding balance = $2975 - $446.25 = $2528.75

20% of outstanding balance

= 20% × $2528.75

= 0.2 × $2528.75

= $505.75

Hire purchase price

= $2975 + $505.75

= $3480.75

c. The difference the hire purchase price and cash price

= $3480.75 - $2975

= $505.75

d. The difference as a percentage of the cash price.

= ($505.75 / $2975) × 100

= 0.17 × 100

= 17%
