Step-by-step explanation:
That is the answer? Is there another question?
A bag of chip = 0.85, let a bag of chip be x
a bag of gatorade is 1.50, let gatorade be y
23.70 is the amount Kennedy spent in all
0.85x + 1.50y = 23.70
step 1: shows the wrong step already, because you shouldn't take out a -0.85, and y is not 0.85 either, but 1.50, so y should still have 1.76 left
so your answer should be step 1.
hope this helps
4x+6y=-12
Make y by itself
6y=-4x-12
y=-2/3x-2
Y intercept: (0,-2)
X-intercept:
0=-2/3x-2
2=-2/3x
x= -3
(-3,0)
Hope that helps
Answer:
it would equal <em>2p-1 </em>as a mathematical equation
Step-by-step explanation:
Answer:
A. P=0.4013
B. P=0.9884
C. P=0.3222
Step-by-step explanation:
We can model this with a binomial random variable.
The sample size is n=10.
The probability is p=0.05 for scrap and p=0.05+0.15=0.20 for degraded or scrap.
The probability of having k scrap gears in the sample is:

The probability that one or more is scrap can be calculated as 100% less the probability that no one is scrap:

The probability that 8 or more are not scrap is equal to the probability of having 2 or less that are scrap:

The probability that more than two are degraded or scrap (p=0.2) is calculated as:
