d - distance
v - speed
t - time
Car A:
Car B:
15 mph faster than car A
Both cars traveled equal distances:
Car B traveled at the speed of 60 mph.
Get all the n together so 3n+2n=5n
5n-17=38
Minus 17 from both sides
5n= 55
N= 11
Answer:
yes they are
Step-by-step explanation:
they are both congruent because they are the same shape and size, they are just on opposite sides
(congruent means that 2 objects are the same shape and size)
D,
You basically see if statements are correct or not. Remember this is sample, sample is portion of population so if everything is dome correctly, the results of sample will also display the results of population +- error (standard deviation). So you can just use the sample results to answer questions about the population.
A is correct because social studies has 4 students and reading has 8. Math has twice.
B is correct because reading has 2 and math has 8. Reading is one fourth of math 8*1/4 = 8/4=2.
D is NOT correct because math is 8, social studies is 4. Math is not half of social studies. Social studies is half of math.
Answer:
Mean=9.75
Median = 9.5
Mode = 8,9,10,12
Range = 6
Step-by-step explanation:
Arrange number in ascending order;
6,7,8,8,9,9,10,10,11,12,12,15
Mean = sum of terms/number of terms
=(6+7+8+8+9+9+10+10+11+12+12+15)/12
=117/12
=9.75
Median = middle number in a list; since we have two numbers we add them together and divide by 2
= (9+10)/2
= 19/2
=9.5
Mode = 8,9,10,12 (multimodal) this is when there are more than one mode
Range = highest number - lowest number
=15-9
=6
