Answer:
(3,-4)
Step-by-step explanation:
3x+(first equation)=5
3x+(-x-1)=5
2x-1=5
x=3, solve for y;
y=-3-1, y=-4
b) 8
they were asking you about the rate of increase in students per year
so you take increase in students/years= (224-120)/(2005-1992)=104/13=8
Answer:
Negative correlation.
Step-by-step explanation:
Negative correlation means that as x increases, y decreases
Positive correlation means that as x increases, y also increases.
No correlation means that neither of the two above cases happens.
In the graph, we can see that on the right (when x is negative) the general y values are larger.
As x increases, the y-values decrease.
(Particularly, we could adjust these data with a linear equation with a negative slope)
Then this is a negative correlation.
<h2>= 316</h2><h2>_______________</h2>
<u>Step-by-step explanation:</u>
= 100+[12×{20−(10÷5)}]
= 100+[12×{20−2}]
= 100+[12×18]
= 100+216
= 316

Answer:
The probability is 3/5
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 2 + 4 + 4 + 4 + 2 + 4 = 20 itens.
Of those, 2 + 4 + 2 + 4 = 12 itens have white or red.
So
12/20 = 3/5
