3x + 2y = 6 ⇒ -3x - 2y = -6
-x + y = -2 ⇒ <u>-3x + 3y = -6</u>
<u>-5y</u> = <u>0</u>
-5 -5
y = 0
3x + 2(0) = 6
3x + 0 = 6
<u> - 0 - 0</u>
<u>3x</u> = <u>6</u>
3 3
x = 2
(x, y) = (2, 0)
I got 2/3 .... Is it correct? Seems weird...
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50
Answer:
C
Step-by-step explanation:
Answer:
The correct answer is:
There is a positive correlation because women's weight tend to increase when height increases (D)
Step-by-step explanation:
The units that might be used to measure each variable are:
Height : meter (m) or foot (plural, feet) (Ft.)
weight : kilograms (kg) or Pounds (lb)
A positive correlation is said to occur between two variables when they both move in the same direction, that is, when they both increase or decrease, while a negative correlation occurs when the movement is not in tandem, i.e, as one increases, the other decreases. The relationship between height and weight is a positive correlation because, an increase in height, which is mainly as a result of elongation of bones, leads to an accumulated increase in total body mass, which in turn increases the body weight.
