Kate is randomly choosing a date in the month of August What is the probability that she chooses a two digit number or a prime number

The probability that the date will be two digit prime number=

Step-by-step explanation:

Given,

Kate is choosing a date from August randomly

To find the probability that the date will be two digit prime number

Number of days in August = 31

Days which are two digit and prime are = 11, 13,17, 19, 23, 29, 31

Number of days which are two digit and prime = 7

Formula

Probability of an event = ( number of occurrence of the event)÷(total number of events)

So,

The probability that the date will be two digit prime number=

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
