Answer: 1/6

Step-by-step explanation:

A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.

Odd numbers in a die = 1, 3 and 6

Numbers greater than 4 = 5 and 6

Probability of rolling an odd number = 3/6 = 1/2

Probability of rolling a number greater than 4 = 2/6 = 1/3

We then multiply both values gotten. This will be:

= 1/2 × 1/3

= 1/6

Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.

Goshia [24]

<h3><u>An inequality to show how much he might spend on souvenirs and snacks is:</u></h3>

$x\leq 13.5$

<h3><u>Solution:</u></h3>

Given that,

Gabe went to the amusement park with $40 to spend

His ticket cost $26.50

Therefore,

Total amount she has = $ 40

Ticket cost = $ 26.50

Let "x" be the amount he might spend on souvenirs and snacks

Therefore,

Remaining amount = 40 - 26.50

Remaining amount = 13.5

Thus she can spend less than or equal to $ 13.5 on souvenirs and snacks

Which is represented in inequality as:

$x\leq 13.5$

Thus the inequality is found

Five carpenters worked 15 & 3/4, 15 & 1/4, 17 & 1/2, 12 & 1/2 and 17 & 1/2 hours respectively. What was the

azamat

<u>The total </u><u>labor cost</u><u> of the carpenters is $2296.91</u>

The carpenters worked $15\frac{3}{4} , 15\frac{1}{4}, 17\frac{1}{2}, 12\frac{1}{2}, 17\frac{1}{2}$

<h3>Conversion of Fraction</h3>

Let's convert the mixed fraction to improper fraction

So, we would have

63/4,
61/4,
35/2,
25/2
35/2.

<h3>Working Cost</h3>

Let's sum it up and multiply by the working cost per hour

$63/4 + 61/4 + 35/2 + 25/2 + 35/2 =78.5$

The total labor cost is = total hours worked * hourly rate.

This becomes $78.5*29.26=2296.91$

<u>The total labor cost is $2296.91</u>
