Answer:
Sanjay calculation of Train speed is more than Marcus calculation of Train speed
Step-by-step explanation:
Given in question as
Marcus want to calculate Train speed , covering distance of 0.5 mile in 6 min
Now as we know that Speed = 
Let take this as S1 = 
S1 = 
mile per min
S1 = 
mile per hour
Note 1 hour = 60 min
So, S1 = 5 mile per hour
Now , Sanjay want to calculate the Train speed , covering distance of 6 mile in 0.5 hour
Let take S2 = 
S2 = 
S2 = 12 mile per hour
Hence We can say that Sanjay calculate more Train speed than Marcus .
Answer
To find the x and y-intercept you plug in zero for the corresponding value that you are looking for. For example, if you are looking for x, plug 0 in for y.
To solve x-intercept: To solve y-intercept:
0=-2x-3 add 3 to other side y=-2(0)-3 substitute 0 for x
3= -2x divide 3 by -2 to isolate x y= 0-3
3/-2 = x (3/-2 , 0) is your x intercept y=-3 ( 0,3) is your y-intercept.

Answer:
10 quarters, 23 dimes
Step-by-step explanation:
Make dimes = d and quarters = q. Let the number of dimes and quarters add up to 33 and the value of the dimes and quarters add up to 4.80. The system of equations should look like:
- d + q = 33
- 0.10d + 0.25q = 4.80
Solve for d in the first equation. Subtract q from both sides.
d = 33 - q
Substitute d into the second equation.
0.10(33 - q) + 0.25q = 4.80
Distribute 0.10 inside the parentheses.
3.3 - 0.10q + 0.25q = 4.80
Combine like terms.
3.3 + 0.15q = 4.80
Subtract 3.3 from both sides.
0.15q = 1.5
Divide both sides by 0.15.
q = 10
Substitute this value of q into where we solved for d (d = 33 - q).
d = 33 - (10)
d = 23
Answer:
A. 0.009899
B. 0.005624
Step-by-step explanation:
Data:
Let the probability that an item is defective = 
The probability that the item is not defective = 
The probability that the fifth item is defective = 
= 0.009899
Probability that one in 5 items is defective = 0.005624
