Mathematics

Answer:

(D)

Step-by-step explanation:

Circumcenter of the triangle is the  point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices.

From the figure drawn, E is the circumcenter of the triangle at which the perpendicular bisectors of the sides of a triangle ABC intersects and which is equidistant from the three vertices that are A, B and C.

Thus, the option which best describes the circumcenter of a triangle is (D.) the point where the perpendicular bisectors of the three sides of the triangle intersect.

A stem and leaf plot (histogram) shows the mode as the longest list of "leaves." It is the easiest to use for finding mode.

A box-and-whisker plot tells you nothing about relative frequencies.

A scatter plot or line graph would require careful re-interpretation to determine the mode. If the amount of data is large and there are many data values with about the same high frequency, these charts may be unhelpful, too.

Martin is considering the expressions 12(7x+48) and − (12x−3)+4(x+5) . He wants to know if one expression is greater than the ot
kenny6666 [7]
The expression 12(7x+48) is greater than (12x-3) +4(x+5)
As,
12(7x+48) = 84x+576 and, 
(12x-3) +4(x+5) = 16x+2
∴ Its clearly shown that 84x+576>16x+2

Step-by-step explanation:

1) 8/2= 4

   4 multiplied by 7 = 28

answer is 28

2) 4x-7=49

        add 7 to both sides

    4x=49+7

     4x=56

         divide 56 by 4

    56/4=12

answer is 12

What is the standard deviation of the following data set rounded to the nearest tenth?
tamaranim1 [39]
Formula\ for\ standard\ deviation\ :\\\\
x=\sqrt{y^2}\\
y-variance\\\\
y^2=\frac{(a_1-a)^2+(a_2-a)^2...+(a_n-a)^2}{n}\\
n-amount\ of\ numbers\\
a-mean\\\
a=\frac{11+5+12+8+5+12+10}{7} =\frac{63}{7}=9\\\\
y^2=\frac{(11-9)^2+(5-9)^2+(12-9)^2+(8-9)^2+(5-9)^2(12-9)^2+(10-9)^2}{7}
\\y^2=\frac{(2)^2+(-4)^2+(3)^2+(-1)^2+(-4)^2+(3)^2+1^2}{7}=\\ \frac{4+16+9+1+16+9+1}{7}=\frac{56}{7}=8\\\\
x=\sqrt8=2\sqrt2
