earnings = $7 per hour

He needs at least $230 . This means he needs an amount greater than or equals to $230.

let

t = hour many hours he works

Therefore,

7t\ge230\begin{gathered} 7t\ge230 \\ t\ge\frac{230}{7} \\ t\ge32.8571428571 \\ t\ge33 \end{gathered}

He needs to work approximately 33 hours or more to get at least $230 for his sterio. This means t is greater than or equals to approximately 33.

Find the mean for the set of data.<br> 0.2, 0.21, 0.17, 3.22, 0.2
Sholpan [36]

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Here are the first five terms of an arithmetic sequence.
Assoli18 [71]

Answer:

The nth term of an AP will be 27 -7n.

Step-by-step explanation:

First five terms of the Arthemetic Sequence is given to us , which is 26 , 19 , 12 , 5

Hence here Common Difference can be found by subtracting two consecutive terms . Here which is 19 - 26 = (-7) .

Here first term is 26 .

And the nth term of an AP is given by ,

★ T_n = a + ( n - 1) d

<u>Subst</u><u>ituting</u><u> respective</u><u> values</u><u> </u><u>,</u>

⇒ T_n = a + ( n - 1 )d

⇒ T_n = 26 + (n - 1)(-7)

⇒ T_n = 26 -7n+1

⇒ T_n = 27 - 7n

<h3><u>Hence </u><u>the</u><u> </u><u>nth</u><u> </u><u>term</u><u> of</u><u> an</u><u> </u><u>AP</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>found </u><u>using </u><u>T_</u><u>n</u><u> </u><u>=</u><u> </u><u>2</u><u>7</u><u> </u><u>-</u><u> </u><u>7</u><u>n</u><u>. </u></h3>
