Step-by-step explanation:

When the car stops, the speed is zero.

When S = 0, -10t + 45 = 0, t = 4.5.

Hence it will take 4.5 seconds for the car to stop.

zavuch27 [327]

Answer:

The possible values for X is: {0,1,2,3,....,12}

Yes, it is a discrete random variable.

Step-by-step explanation:

Consider the provided information.

We need to determine whether the variable is discrete or not.

Discrete variables are which can only take on a finite number of values.

Let the variable X be the number of unbroken eggs in a randomly chosen standard egg carton.

In a standard egg carton we can put 12 eggs.

Therefore, the possible values for X is: {0,1,2,3,....,12}

The number of unbroken eggs (X) can take infinite values, thus by the above definition it is a discrete random variable.

Your question was incomplete. Please refer the content below:

Washington high school's head tennis coach, Ms. racket, runs a tennis camp for middle school students every summer. the students bring their own lunches, but Ms. racket provides them with snacks. there is a proportional relationship between the number of students who enroll in Ms. racket's tennis camp, x, and the total number of snacks she buys, y. what is the constant of proportionality? write your answer as a whole number or decimal. snacks per student.

X      Y

10     30

13     39

14     42

21     63

The constant of proportionality is 3 as for 1 student she buys 3 snacks.

The constant of proportionality means the ratio between the terms x and y.

It is calculated by dividing y by x.

Here we get that:

X      Y           constant of proportionality(Y/X)

10     30                               3

13     39                               3

14     42                               3

21     63                               3

Therefore, we get the constant of proportionality as 3.

Help me with this please everyone
cupoosta [38]
First, let's simplify each expression by combining like terms:

A: 9x-3x-4 = 6x-4

B: 12x-4 = 12x-4 (Already Combined terms)

C: 5x+x-4 = 6x-4

When looking at the list of equations, it is clear that only Expression A and C are equivalent. Brianna failed to combine like terms and plug in more points than 0. 

I Hope this Helps!
