A code consist of a two digit number chosen from 00 to 49 followed by a letter of the alphabet. What is the probability the code
levacccp [35]

Answer:

<em>The probability that code is 14z will be \frac{1}{1300}</em>

Step-by-step explanation:

From 00 to 49, there are total 50 two-digit numbers.

The total number of alphabets is 26.

So, the probability of choosing 14 from all 50 two digit numbers will be:  \frac{1}{50}

and the probability of choosing 'z' from all 26 alphabets will be: \frac{1}{26}

Thus, the probability that code is 14z is = \frac{1}{50}\times \frac{1}{26}=\frac{1}{1300}

sergeinik [125]

Isaiah will mow 9 lawns in 3 hours at the given rate.

We will find unit rate in terms of lawns;

75 lawns = 25 hours

1 lawn = \frac{25}{75}=\frac{1}{3}\ hour

9 lawns = \frac{1}{3}*9

9 lawns = 3 hours

Isaiah will mow 9 lawns in 3 hours at the given rate.
