Answer: Answer A: Both classes have a range of 45
Step-by-step explanation:
above the two graphs we can see a number line ranging from 50-100
bellow that, we can see 2 box and whisker plots, one for second period and one for fourth period. the larger rectangular boxes show all the number results, the line in between them states the average result. Both lines have starting points at 55 and ending points at 100.
100-55=45 45 being the range. Since 2nd and 4th both share the same range answer A could possibly be correct
B is wrong because 2nd period has a median of 90
C is wrong because no periods have a median of 100
D is wrong because most of the students scored an 85+
conclusion: answer A is correct
Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:
Subtract 6x from both sides:
Subtract 2 to both sides:
Answer:
14.9 min
Step-by-step explanation:
r=rate
r25=5*7
r25=35
r=35/25
r=1.4
substitution
r160=t*15
t=time
r=1.4
1.4*160=t*15
224=t*15/15
224/15=t
14.9 min
Answer:
1 cm=8 km
Step-by-step explanation:
We can use a ratio to determine the scale. Take the distance on the map on the left and the "real distance" on the right
6 cm=48 km
Divide by 6
6 cm/ 6 = 48 km /6
1 cm=8 km
Answer:
5 days
Step-by-step explanation:
1/2 + 1/2 = 3 (2 days) times by 2 makes it 4 days and finally 5th day 7 1/2
