Answer:
Step-by-step explanation:
The length of an injected-molded plastic case that holds tape is normally distributed with a mean length of 90.2 millimeters and a standard deviation of 0.1 millimeters. a. What is the probability that a part is longer than 90.3 millimeters or shorter than 89.7 millimeters
Answer:
2x^2-29 its A
Step-by-step explanation:
5x-5=-25
2x-2=-4
-25+-4=-29
X x X=x^2
X^2 + X^2=2x^2
The value of a from the equation is -63.
Here we have to find the value of a.
Given data:
The equation is = x³ + 8x² + ax -2
The equation is divisible by x -1
So we have:
x -1 = 0
x = 1
Now putting the value in the equation we get the remainder as o because the equation is divisible by x -1.
So;
1³ + 8² + a(1) - 2 = 0
63 + a = 0
a = -63
Therefore we get the value of a as -63.
