Exactly 20% of the students in a school wear glasses. Sixty-five students are randomly selected to determine the probability tha

garik1379 [7]

Answer:

A binomial probability density function should be used because the question asks for determining the probability that exactly 10 students wear glasses.

Step-by-step explanation:

A binomial probability density function is used when we want to know the probability of an exact value.

A cumulative distribution function is used when we want to know the probability of less than or equal to a value.

For each function, y varies directly with x. Find each constant of variation. Then find the value of y when x=-0.3

Viktor [21]

Answer:

1- The constant of variation is $\frac{10}{3}$

2- The constant of variation is $\frac{4}{3}$

Explanation:

When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa

A direct variation relation is represented as follows:

y = kx

where k is the constant of variation

Now, to get the constant of variation, all we have to do is substitute with the given x and y variables and solve for k

For the given problems:

1- $y = \frac{2}{3}\ when\ x=0.2$ 

Therefore:

$y = kx\\\\\frac{2}{3} = 0.2k\\\\ k = \frac{10}{3}$

2- $y = 4\ when\ x=3$ 

Therefore:

$y = kx\\ 4 = 3k\\ k = \frac{4}{3}$

Hope this helps :)

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

I hope that helps you!! ^-^
