The first y equals -3 and the second y equals -9
Answer:
a^2-1
Step-by-step explanation:
(a+1)(a-1)
=a^2-1
The answer is A.
From looking at the A graph, you must plug in the x variable into<span> y = -2x + 4.
y = -2(0) + 4 = 4
y = -2(1) + 4 = 2
y = -2(2) + 4 = 0</span>
Answer:
=11x=qrst/x
Step-by-step explanation:
Mean weight of the bag of pears = u = 8 pounds
Standard deviation = s = 0.5 pounds
We have to find what percentage of bags of pears will weigh more than 8.25 pounds. This can be done using the z score.
We have to convert x = 8.25 to z scores, which will be:
z score = 0.5From the z table, the probability of z score being greater than 0.5 is 0.3085
Therefore, the probability of a bag to weigh more than 8.25 pounds is 0.3085
Thus 0.3085 or 31% (rounded to nearest integer) of bags of pears will have weight more than 8.25 pounds at the local market.
