Answer:
Step-by-step explanation:
first, you have to recognize that the two angles will be the same. They are like that b/c of how they are opposites. next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)
29 = 4x -1
29 + 1 = 4x -1 + 1
30 = 4x
30/4 = 4x /4
7.5 = x
now to find ∠DCE just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.
Answer:
A. For a lot of people, drinking beer causes a desire for ice cream, or vice versa.
Explanation:
We can conclude from the monthly sales that when a lot of people drink beer, a lot of people tends to take ice cream, and when less people take beer, less people tends to take ice cream, the fact shows that there is a correlation between the sales of beer and the sales of ice cream.
Answer:
A, B, D
Step-by-step explanation:
It's not C because the correlation coeffecient connot be greater than 1 or less than -1.
<span>lets assume number of iphones sold = a
number of ipads sold = b
i sold 4 iphones more than ipad that becomes
a = b+4
then the equation of total commission becomes
30a+20b = 520
substituting a =b+4 in the above equation
30(b+4)+20b = 520
30b+120+20b = 520
50b =520-120
50b = 400
b = 400/50
b=8
number of iphones i sold = a = b+4 = 8+4 = 12
number of ipads i sold = 8
so i sold 12 iphones and 8 ipads to earn the commission of $520</span>
