Answer:
7/2 or 3.5
Step-by-step explanation:
The y-axis represents the cost is dollars. The x-axis is the amount of gasoline in gallons. To find the cost in dollars per gallon, choose a point on the graph, and divide the dollars (y-coordinate) by the gallons (x-coordinate).
cost = (21/4) / (3/2)
cost = 21/4 * 2/3
cost = 42/12
cost = 7/2 = 3.5
Total beads = 42 + 28 + 12 + 18 = 100
Not yellow or green = 12 + 18 = 30
P(not yellow or green) = 30/100 x 100 = 30%
Total beads = 42 + 28 + 12 + 18 = 100
Red or green = 18 + 28 = 46
P(red or green) = 46/100 x 100 = 46%
Answer: <span>The probability of Kayla not drawing a yellow or a green bead is 30%.
</span><span> The probability of Kayla drawing a red or a green bead is 46%. </span>

i don't know. it doesn't depend my major. so hard for me
According to the model, the year will the population exceed 470 million is 2060
What is the first step to take?
The first step in this case is to use the model to compute the population figure in each year as shown below:
N = 3.21t + 277.3
Year 2020:
t=20
N = 3.21(20) + 277.3
N=341.50
Year 2025:
t=25
N = 3.21(25) + 277.3
N= 357.55
Year 2030:
t=30
N = 3.21(30) + 277.3
N=373.60
Year 2035:
t=35
N = 3.21(35) + 277.3
N= 389.65
Year 2060:
t=60
N = 3.21(60)+ 277.3
N= 469.90
Year 2065:
t=65
N = 3.21(65)+ 277.3
N= 485.95
Since all the years given do not give the correct year, let us equate the target population figure to the model and solve for t
470= 3.21t + 277.3
470-277.3=3.21t
192.70=3.21t
t=192.70/3.21
t=60.03(approximately 2060)
