Answer:
307.5
Step-by-step explanation:
He drove 123 miles in 2 hours. If you go 100 miles in 2 hours that means you went 50 miles in one hour right? Using the same logic we can convert 123 miles in 2 hours to 61.5 miles per hour and then multiply it by 5.
Step 3: 4x+8=4
Step 4: 4x=4-8 ⇒4x=-4
Answer: Step 4: 4x=-4
Step 5: x=-4/4=1
A(n) = D. value of the nth term
a = C. value of the first term
n = A. number of the nth term
d = common difference
Answer:
Angle 1 is the alternate exterior angle.
Answer: A B
Group A 0.25 0.75
Group B 0.45 0.55
Step-by-step explanation:
Since we have given that
Number of people of A in Group A = 15
Number of people of B in Group A = 45
Number of people of A in Group B = 20
Number of people of B in Group B = 25
Total number of people in Group A = 15+45 = 60
Total number of people in Group B = 20+25 = 45
So, Relative frequencies will be given below:
Relative frequency of A in Group A is given by
![\frac{15}{60}=0.25](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B60%7D%3D0.25)
Relative frequency of B in Group A is given by
![\frac{45}{60}=0.75](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B60%7D%3D0.75)
Relative frequency of A in Group B is given by
![\frac{20}{45}=0.45](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B45%7D%3D0.45)
Relative frequency of B in Group B is given by
![\frac{25}{45}=0.55](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B45%7D%3D0.55)
Hence, A B
Group A 0.25 0.75
Group B 0.45 0.55
