Step-by-step explanation:
Yes!
Answer:
- a) j+c=310; j-c=40
- b) (j, c) = (175, 135)
- see attached
- Jose earned $175; Camden earned $135
Step-by-step explanation:
Let j and c represent Jose's and Camden's earnings, respectively.
(a) One equation can be written for the total; another for the difference:
j + c = 310 . . . . their total earnings
j - c = 40 . . . . . the difference in their earnings
__
(b) It is convenient to add these two equations to eliminate c:
(j +c) +(j -c) = (310) +(40)
2j = 350
j = 175
Then c can be found as ...
c = j -40 = 175 -40 = 135
The solution is (j, c) = (175, 135).
__
(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.
__
(d) Jose earned $175 over the summer; Camden earned $135.
x + 12/x + 2 = x/x + 8 <- multiply each side by x
x^2 + 12 + 2x = x + 8 <- rearrange
x^2 + x +4 = 0
Your formula is incorrect as,
Answer:
Gender is a categorical variable. The sum gives the total number of students in class.
Step-by-step explanation:
We are given the following in the question:
The variable Male, is categorical, even though its values are numbers.
Categorical variable:
- These variable are the non parametric variable.
- They do not need values to express the data.
- They only use number and numerical to express the data or represent the data.
- There is no relation with true value of numerical.
Thus, gender is a categorical variable. Numbers are only used to represent the data.
Numbers are just a representation.
The sum of these represent the total male and female students in class. Thus, the sum gives the total number of students in class.
