Losing 30% of its value is the same as saying it is now worth 70% of its original value. To find 70% of 50,000 you can do 50,000 x 0.7. The answer will be the new value of the car after one year. After two years you are essentially finding 70% of the new value which is 70% of the original. More simply, it is 50,000 x 0.7 x 0.7. An equation for this (and the answer to 1b) is 50,000 x 0.7^t where t is the number of years.
1a (i) is $10500 (50,000 x 0.7^1)
(ii) is $2521.05 (50,000 x 0.7^5)
(iii) is $1412.38 (50,000 x 0.7^10)
1b 50,000x0.7^t
Answer:
Step-by-step explanation:
you have to multiply the bracets by the factor
then add +1 to both sides
Equation :
yes, it's the same as b
Answer:
In repeated sampling, 95% of the intervals constructed would contain the population mean.
<h3><u>Answer</u><u>:</u></h3>
<h3><u>S</u><u>olution</u><u>:</u></h3>
In the given right angled triangle, we have :
- Base ( BC ) = 5
- Hypotenuse ( AB ) = 6
- Perpendicular ( AC ) = ?
<u>Using </u><u>Pythagoras </u><u>theorem</u><u>:</u>
➙ H ² = B² + P ²
➙ AB² = BC² + AC²
➙ 6² = 5² + AC²
➙ AC² = 6² - 5²
➙ AC² = 36 - 25
➙ AC² = 11
➙ AC = √ 11
<u>➙ AC = 3.32</u>
<u>➲</u><u> </u><u>M</u><u>o</u><u>r</u><u>e</u><u> </u><u>information</u><u>:</u>
- According to Pythagoras theorem,In a right angled triangle, the square of the Hypotenuse is equal to the sum of square of base and Perpendicular.
