Answer:
1.$3÷12=0.25
each egg would cost 25 cents
2.12×18=216
216×25=5,400
Answer:
a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.
Step-by-step explanation:
<u> Population:-</u>
<em>The totality of observations with which we are concerned, whether this number be finite or infinite is called population.</em>
<em>Given data population is 376 teachers at a university were female'</em>
<u><em>Sample:-</em></u>
A sample is a subset of a Population
sample of given data = 14teachers
The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.
<em />
<em> = 3.72%</em>
When we talk about free form shapes, it can be curve, lines or simple concave or convex polygons.
1. The shape can be closed or open.
2. The curve can cross each other, that is lines or doodled lines may intersect.
3. The free form shape consist of either lines or doodled lines, which we call an open curve.
When we talk about Geometric Shapes, it consist only of Polygons, which consist of triangles, Quadrilaterals, polygons.
1. The curve is simple closed curve.
2. It consist entirely of line segments.
3. The intersection within the curve is a point.
A.In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10.
correct:
90(10 - 12) = 90 · 10 - 90 · 12 or 90(10 - 12) = 90 · (-2)

Trying to factor by splitting the middle term
2.1 Factoring 8x2-6x-3
The first term is, 8x2 its coefficient is 8 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 8 • -3 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -6 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
8x2 - 6x - 3
