Answer:
it is 4/45
Step-by-step explanation:
i wrote down and did the work on a piece of paper
192 people should prefer Company B.
32+75+18=125
750/125=6
32*6=192
Answer:
The response to this question can be defined as follows:
Step-by-step explanation:
For point a:
For point b:
For point c:
For point d:
D.
first, eliminate B and C, because the highest degree in these two equation is 3, a 3-degree equation has 3 roots, not 4.
between A and D, A has the roots 0, 0, 7, and -7, all real roots.
D can be factored into (x²-49)(x²+1)=0
x²=49 or x²=-1
x=7 or -7, x=i or -i two real roots, two unreal roots
for the second equation:
first, find the first term by using the formula:
the nth term=the first term + (n-1)*difference
you are given the 13th term and d=3.7
a13=a1+(13-1)d
1.9=a1+12*3.7
a1=-42.5
the sum of the first 13 terms is S=(a1+a13)*(13/2)=(-42.5+1.9)*6.5=-263.9
The answer would be D. (11,14),(8,18)
To find the answer you need to find an equal slope.
To find the slope you need to do y2-y1/x2-x1
Y2 is 18, y1 is 13, x2 is 8, and x1 is 11
18-13/8-11
5/-3=
-5/3
