Answer:
<em><u>x = -0.5</u></em><em> </em>
Step-by-step explanation:
<em>You need to combine like terms</em>
x * 2 + 5x = -6
<em>Add x to 5x</em>
6x * 2 = -6
<em>Divide 2 from both sides</em>
6x = -3
<em>Divide 6 from both sides to get x alone</em>
x = -0.5
<em>Hope this helps</em>

Step-by-step explanation:
A=a+b
2h=15+25
2·5=100
We are given:
p = probability = 0.12<span>
n = total students = 39 </span>
x = left handers = 5<span>
u = mean = p* n = 4.68
σ = standard dev = √ ( n*p*(1-p)) = √ ( 39 * 0.12 * 0.88 ) =
2.03</span>
Calculating for the z score:
z = (x – u) / σ<span>
z = (5 – 4.68) / 2.03</span>
<span>z
= 0.1576 = 0.16
</span>
Using the standard tables for z, the p value is:
p value = 0.5636 = 56.36%
Hence there is a 56.36% chance.
