Answer: x= 12
Step-by-step explanation:
3x+6 = 42
or, 3x = 36
so, x = 12
<span>Standard deviation shows the distribution present in a set. Range can be used to approximate this property.
Therefore, Set b (100, 140, 150, 160, 200 10, 50, 60, 70, 110) has the largest standard deviation because it has a range of 190 (i.e. 200 - 10)</span>
About 66 percent.
Because 24/36 are women, keep simplifying that divide by 6, 4/6, divide by 2, 2/3 = 0.66 = 66%.
Answer:
y²=4√2.x
Step-by-step explanation:
The focus is at (0,4) and directrix is y=x or x-y =0, for a parabola P.
The distance between the focus and the directrix of the parabola P is
=
{Since the perpendicular distance of a point (x1, y1) from the straight line ax+by+c =0 is given by 
}
Let us assume that the equation of the parabola which is congruent with parabola P is y²=4ax
{Since the parabola has vertical directrix}
Hence, the distance between focus and the directrix is 2a = , {Two parabolas are congruent when the distances between their focus and the directrix are same}
⇒ a=√2
Therefore, the equation of the parabola is y²=4√2.x (Answer)
Answer:
(B), Nominal.
Step-by-step explanation:
A nominal or categorical scale of measurement that is generally used to label or categorize the variables.
The person's "favorite sport" depicts the nominal scale of measurement.
Hence, the correct option is (B), Nominal.
