Answer:

$p = \frac{1564}{5020} = 0.3116$

Step-by-step explanation:

The point estimate for the population proportion is the number of sucesses divided by the size of the sample.

In this problem, we have that:

A success is being a tradition hogan in the reservation(the population). In a sample of 5020, 1564 are traditional hogans.

So $p = \frac{1564}{5020} = 0.3116$

Answer:

48%

Step-by-step explanation:

The conditional probability definition applies.

P(med | cold) = P(med & cold) / P(cold)

The probabilities are the table numbers divided by the total of all numbers in the table (100). Since that dividend is the same for all, we can basically ignore it and just use the table numbers.

P(med | cold) = (12)/(8+12+5) = 12/25 = 48/100

P(med | cold) = 48%

Amir buys a new car for £16470. The value of the car will depreciate by 2% each year. Work out how much amir's car will cost aft

Ronch [10]

Answer:

Amir's car will cost £10348.88 after 23 years.

Step-by-step explanation:

I finally found a UK human!

This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.

The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.

16470 × $0.98^{23}$ = £10348.88
