What is an equivalent form of 14(p + 6) − 10(2q + 5)?
aalyn [17]

The equivalent form of 14(p + 6) − 10(2q + 5)  is 14p − 20q + 34.

<h3>What is mathematical expansion?</h3>

An mathematical expansion occurs when a mathematical object is been scaled using a  scale factor that is greater in absolute value than one.

14(p + 6) − 10(2q + 5)  

If we open the bracket, we have

14p − 20q + 34

Therefore option D is correct.

To raise money for a local charity, students organized a wake-a-thon
arsen [322]

Answer:

a) T= 3.125h

b) $75

Step-by-step explanation:

Given: We know Tania raised $50 for staying awake 16 hours. We also know the amount of money raised varies directly with the time.

We can divide $50 into 16 hours.

50/16 = 25/8

25/8 = 3.125

3.125 = 3 1/8 (You can use a fraction or decimal, whichever is preferred)

That's how much money she earns per hour. It may not make sense because you have 1/8 of a dollar, so it's okay if you're a little confused on that.

Now let's answer the first question: Write an equation relating the money Tania raised and the  amount of time, in hours, she stayed awake.

We know Tania earns $3.125 per hour, so we can make it this equation

T= 3.125h

T can represent Tania's earnings, and 3.125 is how much she earns h, hourly.

Now onto the second question: How much would she have raised by staying awake for 24 h?

We need to multiply 3.125, or 3 1/8, 24 times. Your answer should be $75.

(I apologize in advance if I misread something or made a mistake)

What is the mean absolute deviation of the data set?<br><br> 2, 2, 5, 6, 8, 4, 8, 5
DedPeter [7]

ANSWER

The mean absolute deviation is 1.75

EXPLANATION

The given date set is 2, 2, 5, 6, 8, 4, 8, 5

The mean is

\bar X =  \frac{2 + 2 + 5 + 6 + 8 + 4 + 8 + 6}{8}  = 5

The mean absolute value deviation is given by:

=\frac{ \sum |x -\bar X| }{n}

=  \frac{ | 2 - 5|  +  |2 - 5|+  |5- 5|+  |6 - 5|+  |8 - 5| +  |4 - 5|+  |8- 5|+  |5 - 5| }{8}

=  \frac{ 3  +  3+ 0+  1+  3 + 1+3+  0}{8}

=  \frac{14}{8}

= 1.75

The midpoint between (3,5) and (-2,1) would be:

Apply the formula:

x1+x2 / 2 , y1 + y2 / 2

= 3 + (-2) / 2, 5 + 1 /2

= 1/2, 6/2

= 1/2 ,3 or 0.5, 3 is the same
