Just divide them and see which one gives you 60.
300 / 6 = 50
300 / 5 = 60
240 / 6 = 40
240 / 5 = 48
Therefore B has a unit rate of 60 MPH.
Answer:

Step-by-step explanation:
I really don't know at all
The formula for the sum of the squares of the deviations is
SS = s² (N -1)
We are given
SS = 316
N = 9
Substituting
316 = s² (9 - 1)
Solving for s
s = 6.28
The standard deviation is 6.28
Answer:
We have 8 more boys than girls on the swim team.
Step-by-step explanation:
The ratio of boys to girls on a swim team is represented as:
4 : 2
Total number of athletes is given as 24
Total ratio is given as:
4 + 2 = 6
Step 1
We find the number of boys and girls
Number of boys = 4/6 × 24 = 16 boys.
Number of girls = 2/6 × 24 = 8 girls.
Therefore, since we have 16 boys and 8 girls on the swim team, we have 8 more boys than girls on the swim team.
1=63
3=163
4=325
I hope this answered your question
