Which of the following random variables is geometric?
yawa3891 [41]

Answer:

b. The number of digits in a randomly selected row until a 3 is found.

Explanation:

A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.

In statistics and probability, random variables are either continuous or discrete.

1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.

2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.

Also, any random variable that meets certain conditions defined in a research study.

Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.

In a certain isosceles triangle, the base is $1\frac 12$ times as long as each leg and the perimeter is $63. $ how long is the b
V125BC [204]

The length of the base of the isosceles triangle is: 27 units long.

<h3>What is an isosceles Triangle?</h3>

A triangle with two equal legs and a base is called an isosceles triangle.

Thus:

Let x represent the length of each of the equal legs of the isosceles triangle.

Therefore:

The length of the base = 1 1/2(x) = 1.5x units

Perimeter = 63

Therefore:

x + x + 1.5x = 63

3.5x = 63

x = 63/3.5

x = 18

The length of the base = 1.5x units

Plug in the value of x

The length of the base = 1.5(18) = 27 units

Therefore, the length of the base of the isosceles triangle is: 27 units long.

Paul, colin and brian are waiters. One night the restaurant earns tips totalling £77. 40. They share the tips in the ratio 2:3:4
EleoNora [17]

Answer:

$17.20

Explanation:

To easily get the ratio figured out between Paul, Colin and Brian, try seeing how much the ratio adds up to. With 2:3:4, there is a total of 9; so take 1/9th of 77.40 to get $8.60

You can convert these ratios to fractions, with Paul getting 2/9ths, Colin getting 3/9ths and Brian getting 4/9ths

As Brian is effectively getting double the amount of money, you can just take the amount Paul is getting in tips and use that as the reference for how much Brian is earning which is $8.60 x 2 or in this case, $17.20
