Y = 3x - 7 . . . . . (1)
6x - 2y = 12 . . . (2)
Putting (1) into (2) gives
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12
Therefore, there is no solution.
Answer:
The value of the test statistic is 
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
Test if the mean is equal to 5:
This means that the null hypothesis is 
A simple random sample of wrist breadths of 40 women has a mean of 5.07 cm. The population standard deviation is 0.33 cm.
This means that 
Find the value of the test statistic?
The value of the test statistic is
Answer:
A. y = 17x
B. 867 fluid ounces
C. 3 bottles
Step-by-step explanation:
There are few bottles of water that each contain 17 fluid ounces of water.
A. If the number of bottles is given by x and the total volume of water those bottles contain is y in fluid ounces, then the equation that relates x and y is
y = 17x ...... (1) (Answer)
B. If x =51, then the volume of water in 51 bottles will be given by equation (1) as
y = 51 × 17 = 867 fluid ounces. (Answer)
C. If y = 51 fluid ounces, then from equation (1), the number of bottles will be given by x = 51/17 =3 bottles. (Answer)
-2x+4=3
move the 4
-2x+4=3
-4 -4
-2x=-1
then you would move the -2 by using division
-2x=-1
__ __
-2 -2
x=0.5
Answer:
the y-intercept is -1, or (0, -1)
Step-by-step explanation:
Identify the coordinates of the point where the line crosses the y-axis. They are (0, -1), and so the y-intercept is -1, or (0, -1).
