Mai is given these two systems of linear equations to solve: System 1: 5x + y = 13
System 2: 20x + 4y = 64
50 + y = 13
20x = 52 – 4y
She analyzed them for a moment, and then-without graphing
the equations-said, "I got it! One of the systems has no solution
and the other has infinitely many solutions!" Mai is right!
Which system has no solution and which one has many
solutions? Explain or show how you know (without graphing the
equations)

pleaseee i need help with this

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
