Answer:
I believe the answer is B. 6.9
Step-by-step explanation:
Answer: 0.6065
Step-by-step explanation:
Given : The machine's output is normally distributed with
Let x be the random variable that represents the output of machine .
z-score :
For x= 21 ounces
For x= 28 ounces
Using the standard normal distribution table , we have
The p-value :
Hence, the probability of filling a cup between 21 and 28 ounces= 0.6065
Answer: x=-1 and y=6
Steps:
So two of the equations are, " 8x+y=-2" and " -5x-2y=-7 "
8x+y=-2
8x= -2-y
x= (-2-y)/8
Now place this equation for x on the other equation.
-5 * {(-2-y)/8} -2y=-7
(10 + 5y)/8 -2y = -7
(10 + 5y - 16y)/8 = -7
10 - 11y = -7 * 8
-11y= -56 - 10
y= - 66/-11
y= 6
Now place the value of y in the first equation
8x + 6 = -2
8x= - 2 - 6
x= -8/8
x= -1
