The graph shows the motion of two cars starting at different places on a highway. Their speeds can be compared by comparing the

steepness of the graphed lines.
Use the drop-down menus to complete the statements.
Car a travels (50,100,200,300) miles in 6 hours Car B travels (50,100,200,300) miles in 5 hours
Car A speed is (40,50,60,125,) miles per hour Car B speed is(40,50,60,125) miles per hour.
Car A traveled (faster than,slower than, the same speed) as Car B.
The graph for Car A is(steeper than,less steeperhan, or same steepness) as the graph for Car B

Answer:

Car a travels (300) miles in 6 hours

Car B travels (200) miles in 5 hours

Car A speed is (50) miles per hour

Car B speed is(40) miles per hour.

Car A traveled (faster than) Car B.

The graph for Car A is(steeper than) the graph for Car B

Step-by-step explanation:

distanc \:  = x - y

where x is starting location and y is the ending location

speed \:  =  \frac{distance}{time}

the rest we see once we have solve for distance and speed of the 2 cars

Sophie [7]
Equally divide 56 into 2 halves. 28 liters. 28 liters for muffins and 28 liters for cakes.
 
(muffins require 7 liters) 28÷7= 4
(cakes require 4 liters) 28÷4=7
x= 4 batches of muffins
y= 7 batches of cakes.

Answer:

P(X=7)

And using the probability mass function we got:

P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271  

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:  

X \sim Binom(n=15, p=0.23)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

And we want to find the following probability:

P(X=7)

And using the probability mass function we got:

P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271

What is the solution to the system of equations y23x3 x 2
bija089 [108]

The Solution for the given system of equations is (-2) and (\frac{5}{3}).

The given are linear equations as follow:
y = \frac{2}{3}x + 3              .. ... ...(1)
and x  = -2.          .. .... ...(2)

We already know the first part of the solution (x) which is -2.  We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = (\frac{2}{3})(-2) + 3
y = \frac{-4}{3} + 3

Taking the L. C. M of denominators which will be '3', we get:

y = \frac{-4 + 9}{3}

y = \frac{5}{3}

So the second part (y) of the solution of the given equation is \frac{5}{3}.

Hence, the overall solution to the given system of equation is (-2, \frac{5}{3}).
