Answer:
Step-by-step explanation:
The x- intercepts of the graph are the roots expressed in factorization form.
In this Case :
When y=0
X=2 or x=1/2
Therefore the factorization expression is: (x-2)(x-1/2) =0
To answer this problem, you have to have a good foundation in factoring polynomial expressions. It has to be taken into account the knowledge in division and fractions.
The expression
(y+7)^2 - 100
can be factored as
[ (y+7) + 10 ] [ (y+7) - 10 ]
Further simplifying the expressions
[ y + 7 + 10 ] [ y + 7 - 10 ]
( y + 17 ) ( y - 3)
So the product of two linear binomials is
(y+17)(y-3)
Part A:
Finding the probability of P(Z < -1.27), we refer to the z-table to the left of the distribution and we have
Therefore
Part B:
Doing the same process as above, however we also need to find the P(Z < 1.68)
Solving for P(-1.27 < Z < 1.68) we have
The coefficient of a is 7
Answer:
yes they would be 1 25/30 and 2 6/30
