iVinArrow [24]

Answer: $0.05

Step-by-step explanation:

Mean of a given set of numbers simply means that one should find the average of the numbers. Therefore, the mean change of the stock prices will be:

= ($1.25 + -$0.75 + $1.25 + -$0.75 + -$0.75) / 5

= $0.25 / 5

= $0.05

Therefore, the mean change of the stock prices is $0.05.

93% of what is 198 tons?<br><br> I dont get this someone help

Vera_Pavlovna [14]

93% of x = 198 tons
93% = 93/100
= 0.93
0.93 * x = 198 tons

Divide both sides by 0.93:
x = 198/0.93
x = 212.90 -> Final Answer.

Convert 7x + 3y = −1 to slope-intercept form.

maksim [4K]

Hi there!

Let's solve this problem step by step!

$7x + 3y = - 1$
To convert this formula to slope-intercept form, we must isolate y.

First bring 7x to the left by subtracting 7x from both sides of the equation.
$3y = - 7x - 1$

Finally we need to divide both sides of the equation by 3.
$\frac{3y}{3} = \frac{ - 7x - 1}{3}$

Do some simple algebra and we find:
$y = - \frac{7}{3} x - \frac{1}{3} \\ y = - 2 \frac{1}{3} x - \frac{1}{3}$
~ Hope this helps you!
