These triangles are congruent by SAS, therefore HI and IJ will be the same length.

3v = v + 60

2v = 60

v = 30

Hope this helps!

50 testers can complete 25 test cases in 10 days. All testers are equally productive. A project has 25 testers and 50 test cases

Advocard [28]

It will take to complete cases 4 days per 5 cases.

<h2>Given that</h2>

50 testers can complete 25 test cases in 10 days.

All testers are equally productive.

A project has 25 testers and 50 test cases.

<h3>We have to determine</h3>

How much time will they take to complete?

<h3>According to the question</h3>

50 testers can complete 25 test cases in 10 days.

The number of cases completed per day is,

$= \dfrac{50}{25}\\
\\
= 2$

The number of cases completed per day is 2.

A project has 25 testers and 50 test cases.

The time will they take to complete is 2x.

= 2(2) = 4 days per 5 cases

Hence, they will take to complete cases 4 days per 5 cases.

Two n-digit sequences of digits 0,1,. . . ,9 are said to be of the same type if the digits of one are a permutation of the digit

Stells [14]

Answer:

(n+9)!/(n!9!)

Step-by-step explanation:

A combination is a selection of items from a collection, such that (unlike permutations) the order of selection does not matter.

This is a case of combination with repetition because any n-digit sequence can have numbers repeated. For example in the sequence 00238899 there are 2 zeros.

The formula to find the number of combinations when repetition is allowed is:

(n+N-1)!/[n!(N-1)!]

where

N is the number of elements of the set we can choose from

n is the number of elements we choose

In this case, the set {0,1,2,3,4,5,6,7,8,9} has 10 elements, N=10

The number of n-digit sequences is given by

(n+10-1)!/[n!(10-1)!]=(n+9)!/(n!9!)
