The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
Answer: Null hypothesis : 
Alternative hypothesis : 
Step-by-step explanation:
Let 
be the proportion of women using supplements and 
be the proportion of women who did not to have died during that period .
Then the set of hypothesis for testing if the proportion of women elderly women who use dietary supplements is different than those who do not will be :-
Null hypothesis : [∵ it takes equality sign]
Alternative hypothesis : [∵ it takes ≠ sign to show difference]
Answer:
x = 15
Step-by-step explanation:
The segment that is x units long is the midsegment of the largest triangle. The midsegment is half as long as the line parallel to the midsegment. It is half as long as the 30 unit long segment.
Note how the vertical sides (marked with the double tickmarks) are congruent to one another. The smaller pieces are both the same length, so they combine to something twice as big. Go in reverse: one segment with a pair of double tickmarks is exactly half as long as the entire vertical side. The same can be said about the horizontal sides as well.
Answer:
To figure this out we need to balance out the equation.
When a number is right next a variable, it is considered as multiplication. So, to balance the equation we need to divide.
Step-by-step explanation:
1.2/1.2 =x
1.2/6=5
Answer; x=5
