Answer:

4.8 Liters

Step-by-step explanation:

Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy

Step 1

1 person = 200ml of ice cream

24 persons = x

Cross Multiply

x = 24 × 200ml of ice cream

x = 4800 ml of ice cream

Step 2

How many liters of ice cream should she buy

We convert from Milliliters to Liters

1 milliliters= 0.001 liters

4800 millilitres = x

Cross Multiply

= 4800 × 0.001 liters

= 4.8 Liters

Therefore, she should buy 4.8 Liters of ice cream

Answer:

36.58% probability that one of the devices fail

Step-by-step explanation:

For each device, there are only two possible outcomes. Either it fails, or it does not fail. The probability of a device failling is independent of other devices. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

A total of 15 devices will be used.

This means that n = 15

Assume that each device has a probability of 0.05 of failure during the course of the monitoring period.

This means that p = 0.05

What is the probability that one of the devices fail?

This is P(X = 1)

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{15,1}.(0.05)^{1}.(0.95)^{14} = 0.3658

36.58% probability that one of the devices fail

Which graph represents the function y = 4?
Temka [501]

Answer:

The first one

Step-by-step explanation:

This is a constant function, i.e. the value for y doesn't depend on x. So, every x value will lead to the same y value, in this case 4.

This implies that the graph is a horizontal line, composed by all points like (x,4), where x can be any value and 4 is fixes as the y coordinate.
