If they intersect they have the same x and y values so we can say y=y which can be expressed as:
-7x/8+1/4=-3x/4+1/2 make all terms have a common denominator of 8
-7x/8+2/8=-6x/8+4/8 now multiply all terms by 8
-7x+2=-6x+4 add 6x to both sides
-x+2=4 subtract 2 from both sides
-x=2 divide both sides by -1
x=-2, now we solve for y using either original equation...
y=-3(-2)/4+1/2
y=6/4+1/2
y=6/4+2/4
y=8/4
y=2 so the lines intersect at the point:
(-2, 2)
Bottom right corner box is the answer.
Answer: Frequencies .
Step-by-step explanation:
In statistics theory the chi-square test statistic is calculated by considering each cell and the expected frequency is subtracted from the observed frequency after that the difference is squared, and the total is divided by the expected frequency. This is highlight that the key focus of the chi-square test is the frequencies .
Answer:
m<5= 46 degrees
m<8= 134 degrees
Step-by-step explanation:
m<5: all you need to do is subtract 134 from 180
m<8: m<2 and m<8 have the same angle
