Answer:
C(-4,-2), D(3,-7)

Step-by-step explanation:
we procced to identify points:
A(-4,-7), B(3,-2)
for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)
C(-4,-2), D(3,-7); Area of the rectangle Ar=b*h, where

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=
Answer:
(a) Null hypothesis: The new drug reduces the rate of first heart attacks by a percentage same as aspirin.
(b) Alternate hypothesis: The new drug reduces the rate of first heart attacks by a percentage greater than aspirin.
Step-by-step explanation:
(a) A null hypothesis is a statement from the population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.
(b) An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
The equation for this would be 4x+3=y where x is months and y is your amount of toys after x months.
plug in 4 for x -> 4(4)+3=y
solve -> 16+3=y
y=19
