The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.
Answer:
x = -9
(-5,-3) since plug in a=b-2 into the first equation and then solver for b. You get -3.-3-2=-5 which is a
Answer:
5.14 and 18.86
Step-by-step explanation:
They give us the following information:
mean (m) = 12
standard deviation (sd) = 3.5
For cutting extreme 5% under the normal distribution curve standard normal score is + - 1.96
we have to:
z = (x - m) / sd
Lower limit is
-1.96 = (x -12) /3.5
-6.86 = x - 12
x = 5.14
Upper limit is
1.96 = (x -12) /3.5
6.86 = x - 12
x = 18.86
Therefore, the raw scores are 5.14 and 18.86
