Answer:
The answer is B) 21, 34, 65
Step-by-step explanation:
21 + 34 + 65 = 120
120 divided by 3 = 40.
In order to find the mean you must add up all of the numbers in the numerical data set, then divide that by how many numbers there are. Hope this helps! :)

Answer: Choice B</h3><h3>2W+2( W+4 1/4) = 124 1/2</h3>
=========================================
Explanation:
L = length
W = width
"The length is 4 1/4 longer than the width" (paraphrase) so
L = W + 4 1/4
This means,
P = perimeter = 124 1/2
P = 2L+2W
2L+2W = P
2W+2L = P
2W+2( L ) = P
2W+2( W+4 1/4) = 124 1/2
Answer:
Step-by-step explanation:
Knowing the measure of the <u>three angles</u><u> </u>can help us know if the triangle is acute, obtuse, right, isosceles, or equilateral and also compared with another we can tell if it is similar to another Δ.
Knowing the measures or the <u>three sides </u>of a triangle we can know if the triangle is right, isosceles, or equilateral and also compared with another we can tell if it is congruent or similar with another Δ.
We can see that knowing the sides will tell us more about the <u>congruency of triangles </u>whereas knowing just the angles can tell us that triangles are similar yet we will not know if the triangles are also congruent.

Answer:
-4<1,0>+9<0,1>=<-4,9>
Step-by-step explanation:
i=<1,0>
j=<0,1>
We are required to find scalar multiples c₁ and c₂ such that
c₁i+c₂j=<-4,9>
c₁<1,0>+c₂<0,1>=<-4,9>
<c₁,0>+<0,c₂>=<-4,9>
This implies that
c₁+0=-4
c₁=-4
0+c₂=9
c₂=9
Since we have found the values of the scalar multiples c₁ and c₂, we next express <-4,9> as a linear combination of i and j.
This is given as:
-4<1,0>+9<0,1>=<-4,9>
