Answer:

Amount after given year = $2,290.34 (Approx.)

Step-by-step explanation:

Given:

Principal = $650

Annual interest rate = 6.5%

Time = 20 year

Find:

Amount after 20 year

Computation:

Using compound formula;

A = P[1+r]ⁿ

Where;

A = Amount after given year

P = Principal

r = Annual interest rate

n = Time taken

Amount after given year = 650[1+6.5%]²⁰

Amount after given year = 650[1+0.065]²⁰

Amount after given year = 650[1.065]²⁰

Amount after given year = 650[3.5236]

Amount after given year = $2,290.34 (Approx.)

Solve the simultaneous equations: <br> 5x + 2y = 17<br> 4x + y = 10
erik [133]

Answer:

(1, 6 )

Step-by-step explanation:

5x + 2y = 17 → (1)

4x + y = 10 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the y- term

- 8x - 2y = - 20 → (3)

Add (1) and (3) term by term to eliminate y

- 3x + 0 = - 3

- 3x = - 3 ( divide both sides by - 3 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for x

Substituting into (1)

5(1) + 2y = 17

5 + 2y = 17 ( subtract 5 from both sides )

2y = 12 ( divide both sides by 2 )

y = 6

solution is (1, 6 )

Below are 36 sorted ages of an acting award winner. Find Upper P70 using the method presented in the textbook.
Leona [35]
The upper 70th percentile is the number below which 70% of the data lie.

The 70th percentile position is given by:

P_{70}= \frac{70N}{100} = \frac{70(36)}{100} =25.2

Thus, the 70th percentile position is approximately the 25th data item (after the data has been arranged in acsending order).

Given the following data:
<span>16 24 25 26 27 29 36 39 39 39 40 44 45 47 47 48 50 51 51 53 53 54 57 58
58 60 65 66 67 69 69 71 72 74 74 74

The 25th data in the data set is 58.

Therefore, the upper P70 is 58.

Jasmine’s race time was 34.287 minutes.round her race time to the nearest 10th of a minute
amm1812
Hi!

34.287 rounded to the nearest tenth is 34.290

This is because 7 is greater than 5, so we would round it to the cloest tenth that is slightly higher than 7. =)
