Answer:

The percentage rate per annum is 2.8%

Step-by-step explanation:

We need to multiply the principal by the time, then divide the interest by the product of P×T, so:

1,600 × 5 = 8,000

224 ÷ 8,000 = 0.028

Then we convert our final product to a percentage.

0.028 to a percent is 2.8%

6. a. Sixty students in a class took an examination in Physics and Mathematics. If 17 of them passed Physics only, 25 passed in
Ivahew [28]

Let C be the set of all students in the <u>c</u>lassroom.

Let P and M be the sets of students that pass <u>p</u>hysics and <u>m</u>ath, respectively.

We're given

n(C) = 60

n(P \cap M') = 17

n(P \cap M) = 25

n((P \cup M)') = n(P' \cap M') = 9

i. We can split up P into subsets of students that pass both physics and math (P\cap M) and those that pass only physics (P\cap M'). These sets are disjoint, so

n(P) = n(P\cap M) + n(P\cap M') = 25 + 17 = \boxed{42}

ii. 9 students fails both subjects, so we find

n(C) = n(P\cup M) + n(P\cup M)' \implies n(P\cup M) = 60 - 9 = 51

By the inclusion/exclusion principle,

n(P\cup M) = n(P) + n(M) - n(P\cap M)

Using the result from part (i), we have

n(M) = 51 - 42 + 25 = 34

and so the probability of selecting a student from this set is

\mathrm{Pr}(M) = \dfrac{34}{60} = \boxed{\dfrac{17}{30}}

Solve the formula <br> 2x − 3y = 18 for y.
tensa zangetsu [6.8K]

Answer:

y = \frac{2}{3} x - 6

Step-by-step explanation:

2x - 3y = 18 ( subtract 2x from both sides )

- 3y = - 2x + 18 ( divide terms by - 3 )

y = \frac{2}{3} x - 6
