Find the value of the cot 10° using your calculator.

17. A disposable camera costs $6.95. A party planner wants to buy 100 cameras for an

natima [27]

Answer:

$695

Step-by-step explanation:

So if each camera costs $6.95 snd he wants 100 you would multiply by 100. And that would be 6.95×100=695 and a good trick I've learnt is that you just move the numbers 1 column to the left for each zero so if it was 10 you'd move all the numbers 1 column to the left. It is abit hard to explain but you're answer is there just thought that'd help in future.

The white Christmas tree is 7.55m tall.the green Christmas tree is twice as tall as the white Christmas tree which is 0.454m tal

Alja [10]

The white Christmas tree is 7.55m

Green Christmas tree is twice as tall as white Christmas tree: 7.55 * 2 = 15.1m

High golden Christmas tree: 15.1m - 0.454m = 14.646m

The total height of 3 Christmas trees is: 7.55m + 15.1m + 14.646m = 37.296m

Choose: A 37.296m

In your own words, explain the Normal Distribution and provide a real world example.

elena-14-01-66 [18.8K]

Answer:

The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:

Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:

$X \sim N(\mu , \sigma)$

The two parameters are:

$\mu$ who represent the mean and is on the center of the distribution

$\sigma$ who represent the standard deviation

One particular case is the normal standard distribution denoted by:

$Z \sim N(0,1)$

Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated

A shipping container contains seven complex electronic systems. Unknown to the purchaser, two are defective. Two of the seven ar

kodGreya [7K]

Answer:

$\large\boxed{\large\boxed{10/21}}$

Explanation:

There are only two mutually exclusive possibilities for each complex electronic system: being defective or being not defective:

Number of complex electronic systems: 7
Nmber of defective systems: 2
Number of not defective systems: 5

Probability that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:

Porbability the first is not defective × probability the second is not defective

5/7 × 4/6 = 20/42 = 10/21
