Answer:
16
Step-by-step explanation:
Let S is smart car and T is Toyota car
Case 1: 6 smart cars and 7 Toyota's = 6S + 7T
Case 2: 8 smart cars and 4 Toyota's
When 2 smart cars increase = 3 Toyota's cars descrease
So the ratio between them is:
2S = 3T
<=> S= 3/2T
so the maximum number of toyotas aboard the ferry
6*3/2T + 7T = 16 T
Line through (-4,0) and (0,-2)
Slope is change in y over change in x
m = (-2 - 0)/(0 - -4) = -2/4 = -1/2
Answer: -2/4 = -1/2, second choice
Answer:
Yes. The city has a lower proportion of accidents by 16-year-old male drivers than the national proportion (16.7% compared to 21%).
Step-by-step explanation:
a) Data and Calculations:
Number of 16-year-old males involved in driver accident during year 2000 = 210
Sample number of drivers = 1,000
National rate of accidents for 16-year-old males for every 1,000 drivers = 21% (210/1,000 * 100)
Random sample of 16-year-old male drivers in a Midwest city = 150
Number of them involved in driver-accidents = 25
Proportion of 16-year-old males involved in driver-accidents = 25/150 * 100 = 16.7%
The city's 16.7% proportion is lower than the national proportion of 21%.
Answer:
8 ft
Step-by-step explanation:
The area (A) of a triangle = bh
where b is the base and h the perpendicular height
Using b = 20 and h = 12, then
A = 0.5 × 20 × 12 = 120 ft²
Using b = 30 and perpendicular height = h, then
0.5 × 30 × h = 120
15h = 120 ( divide both sides by 15
h = 8
