Select the correct answer from each drop-down menu. Margie is practicing for an upcoming tennis tournament. Her first serve is g

ood 20 out of 30 times on average. Margie wants to know the estimated probability that her first serve will be good at least four of the next six times she serves. How could she design a simulation for this scenario? The scenario can be simulated by rolling a six-sided die ---- times. The ----- would represent the number of Margie's good first serves. If the ------- appear in a set of outcomes one time each, it would mean that at least four of the next six first serves that Margie makes will be good. 1)2,4,6,10 ------------------------------ 2)numbers 1 to 3 numbers 1 to 4 numbers 4 to 6 numbers 2 to 4. ----------------------------- 3)numbers 0 to 1 numbers 5 to 6 numbers 4 to 6 numbers 1 to 4

Hey there!

GUIDE:

2 negatives = positive

2 positives = positive

1 negative & 1 positive = negative

1 positive & 1 negative = negative


ANSWERING THE GIVEN QUESTION

y = -4x

y = -4(7)

y = -28

Because, remember we said a NEGATIVE (-4) & a POSITIVE (7) gives you a negative [-28]


Therefore, the answer should be: -28


Good luck on your assignment & enjoy your day!

What is porpotinal to 1/5
Irina-Kira [14]

An equation of the form y=ax+b, where y and x are variables, and a and b are constants, is called a linear equation.

The reason it is called linear is because the graph of the equation is a line.

The line passes through the origin only if b=0, as in our problem.

Any line (except vertical lines) represents a proportional relationship in that the change in y is proportional with the change in x. It is not a condition that the line passes through the origin.

In our specific case, y=(1/5)x, means that the change in y is always 1/5 of the change in x. That is, if x changes by 5 units, y changes by 1. If x changes by 10 units, y changes by 2, and so on.

So, the constant of proportionality is 1:5, or 0.2.
