2x + 5y = 10...we put this in slope intercept form...so basically, solve for y
5y = -2x + 10
y = -2/5x + 2...the slope will be in the m position (y = mx + b)...so ur slope is -2/5
or..
(5,0)(0,2)
slope formula : (y2 - y1) / (x2 - x1)
slope = (2- 0) / (0 - 5)
slope = 2/-5 = -2/5
either way should get u the right answer
Answer:
Measure of central tendency (center)
it is called median
Dialation means to shrink something of the original size
Answer:
1) Yes
Product of Means = Product of Extremes
4 × 21 = 7 × 12
84 = 84
2) No
Product of Means = Product of Extremes
2 × 2 = 3 × 3
4 ≠ 9
3) No
Cross multiplying
3 × 6 = 4 × 8
18 ≠ 32
4) Yes
Cross Multiplying
1 × 25 = 5 × 5
25 = 25
So if 3/4 of the seats are filled, there are a few methods we can use.
The simplest method:
Just multiply 3/4 by 500, to get 1500/4, or 375.
So 375 seats are filled.
A method that can be used with harder problems and will be more efficient in those cases:
Using proportions.
You could say,
?/500 = 3/4
And then cross multiply,
500 * 3 = 4 * x (say the ? = x)
1500 = 4x
/4 /4
x = 375
So either way we get the answer, 375 seats were filled.
