Answer:

199 a 426 students

Step-by-step explanation:

first to see what amount we are talking about in each case, let's see how many students each percentage represents

22% of students: (22 * 1420 students) /100 = 312.4 students

8% of students: (8*1420 students)/100 = 114.6 students

that is, that the average number of students who work part time is 312.4 students. And that number can vary up to 114.6 students above and up to 114.6 students below

that can be expressed as

22% + 8% = 312.4 + 113.6 = 426 students

and

22% -8% = 312.4-113.6 = 198.8≅ 199 students

Julli [10]

The mean is the unit of center that may be used to predict how many strokes will be needed to complete the ninth hole.

The data is almost symmetrical, making the mean the best option.

What is symmetrical data?

Asymmetric communications refers to any system where, when averaged over time, the data speed or amount is different in one direction from the other.
Asymmetry is defined as the lack of precise similarity between two pieces.
A fiddler crab's body is asymmetrical, as evidenced by the fact that one of its claws is larger than the other.
Absence of a standard unit of measurement between two things or amounts; incomprehensibility.

So the more about symmetrical visit.

Add 2 + 1 = 3 then 1/2 +1/2 =1
so 3 +1 = 4 and you have 1/4 left so your answer is 4 1/4

What is the remainder of (4x2 + 7x-1)= (4 + x)?<br>A. -9x – 1<br>B.23x – 1<br>C.35<br>D.-37

Answer: I don't know what you meant by remainder but i hope this helps :)

$x=\frac{-3+\sqrt{29}}{4},\:x=-\frac{3+\sqrt{29}}{4}\\$

Step-by-step explanation:

$\left(4x^2+7x-1\right)=\left(4+x\right)\\\mathrm{Refine}\\4x^2+7x-1=4+x\\\mathrm{Subtract\:}x\mathrm{\:from\:both\:sides}\\4x^2+7x-1-x=4+x-x\\Simplify\\4x^2+6x-1=4\\\mathrm{Subtract\:}4\mathrm{\:from\:both\:sides}\\4x^2+6x-1-4=4-4\\\mathrm{Simplify}\\4x^2+6x-5=0\\\mathrm{For\:}\quad a=4,\:b=6,\:c=-5:\\\quad x_{1,\:2}=\frac{-6\pm \sqrt{6^2-4\times \:4\left(-5\right)}}{2\times \:4}$

$\frac{-6+\sqrt{6^2-4\times \:4\left(-5\right)}}{2\times \:4}\\=\frac{-6+\sqrt{6^2+4\times \:4\times \:5}}{2\times \:4}\\=\frac{-6+\sqrt{116}}{2\times \:4}\\=\frac{-6+\sqrt{116}}{8}\\\\Let\: simplify\: ; -6+2\sqrt{29}\\=-2\times \:3+2\sqrt{29}\\=2\left(-3+\sqrt{29}\right)\\=\frac{2\left(-3+\sqrt{29}\right)}{8}\\=\frac{-3+\sqrt{29}}{4}\\$

$\frac{-6-\sqrt{6^2-4\times \:4\left(-5\right)}}{2\times \:4}\\\\=\frac{-6-\sqrt{6^2+4\times \:4\times \:5}}{2\times \:4}\\\\=\frac{-6-\sqrt{116}}{2\times \:4}\\\\=\frac{-6-2\sqrt{29}}{8}\\\\=-\frac{2\left(3+\sqrt{29}\right)}{8}\\\\=-\frac{3+\sqrt{29}}{4}\\\\\\x=\frac{-3+\sqrt{29}}{4},\:x=-\frac{3+\sqrt{29}}{4}$
