The two-way frequency table above shows data on grade level and method of traveling to school for the students at central high school. which of the following statements is true? a) a 10th grade student is more likely to travel by bike than car
b) less than 1/2 of the 11th grade students travel by car
c) 11th grade students are more likely than 9th grade students to travel by bike
d) most students are in 11th grade

c, d

Step-by-step explanation:

a) There are more cars than bike so it should be the opposite for 10th grade students. Therefore, this choice is wrong.

b) There are more cars than any other choice for 11th graders. Therefore, it should be more than 1/2 of the 11th grade students travel by car not less than.

c) In 11th grade, 27 people ride bikes. In 9th grade, 20 people ride bikes. Therefore, more people from 11th grade are more likely to travel by bike. This means this option is correct.  

d) 139 students are in 11th grade, 51 students are on 9th grade, 46 students are in 10th grade, and 44 students are in 12th grades. Because there are more students in 11th grade than any other grade, this option is also correct.

your welcome.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
