Answer:

Step-by-step explanation:

Use the 2 points for which you have both an x and y coordinate to write the equation of the line containing those 2 points.  When you get the equation, sub in the x value of 6 and solve for y.  

Begin by finding the slope of the line:

m=\frac{-13-(-5)}{-4-0}=\frac{-13+5}{-4}=\frac{-8}{-4}=2

Then use one of the points in point slope form to write the equation in slope-intercept form.  I used (0, -5).  But either point you choose will give you the exact same line...promise.

y - (-5) = 2(x - 0) and

y + 5 = 2x and

y = 2x - 5

Now sub in the x value of 6 for x and solve for y:

y = 2(6) - 5 and

y = 12 - 5 so

y = 7

iragen [17]
We have to find how the chess player can move a knight from one location to another.
Also we have to remember that the bottom - left square is labelled ( 1 , 1 ).
First he wants to move a knight from ( 3 , 2 ) to ( 5 , 1 ).
Answer: 2 squares left, 1 square down.
Then he wants to move it from ( 5 , 1 ) to ( 6 , 3 ).
Answer: 2 squares right, 2 squares up, 1 square left.

n 2018, homes in East Baton Rouge (EBR) Parish sold for an average of $239,000. You take a random sample of homes in Ascension p
Olenka [21]

Answer:

Conclusion

   There is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Step-by-step explanation:

From the question we are told that

   The population mean for EBR is  \mu_ 1  = \$239,000

    The sample mean for Ascension parish  is \= x_2  = \$246,000

   The  p-value  is  p-value  =  0.045

     The level of significance is  \alpha = 0.01

The null hypothesis is  H_o : \mu_2  = \mu_1

The  alternative hypothesis is  H_a  :  \mu_2 > \mu_1

Here \mu_2 is the population mean for Ascension parish

   From the data given values we see that  

          p-value  >  \alpha

So we fail to reject the null hypothesis

So we conclude that there is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Now Cathy is three times as old as Katie. In six years Cathy will be only twice as old as Katie. How old is each girl now?
BabaBlast [244]
Katie is 6; Cathy is 18!

X- Katie’s age now and 3x -Cathys age now
In 6 years, Katie is 12 and Cathy is 24.

2 x (X+6) = 3x + 6
2x + 12 = 3x + 6
6 = x

Suppose there are 100 cookies in a jar. if 30 are chocolate chip, 40 are oatmeal raisin, 20 are peanut butter, and 10 are sugar
lubasha [3.4K]
If there's 100 cookies, of which there are 40 oatmeal raisin and 10 sugar cookies, there are 50 out of 100 cookies which you want. Hence by chance, there is a 50/100, or 1 in 2 chance of you obtaining an oatmeal raisin or a sugar cookie.
