Angle R is congruent to Angle Y
Side QR is congruent to side XY
Answer:
Step-by-step explanation:
Equation of line k is y = (-4/7)x + 1
point (-5,-10); m = -4/7
Line L is perpendicular to k so the perpendicular slope will be 7/4
Equation of line L is (y - y1) = m(x-x1)
y+10 = (7/4) (x +5)
4y + 40 = 7x + 35
4y = 7x - 5
y = (7/4)x - (5/4)
The answer is $8.75. You have to find what one costs which is 1.25 so if you have 7. 1.25 times 7 is $8.75
Answer:
14
Step-by-step explanation:
Total number of chips = 500
Percentage of green chips = 28%
P(green chips) = 0.28
Expected number of green chips from a simple of 50
Sample size, n = 50
p of green chips = 0.28
Recall:
Mean, m = n*p
Expected number of green chips = 50 * 0.28 = 14
14 green chips
