Seems to me that if you need help your brain isn’t rlly all that good...i’m good with my brain thanks!
Step-by-step explanation:
<h2>-20 is the right answer.</h2>
Answer:
$50
Step-by-step explanation:
x is distance and y is cost because the cost is dependent on the distance which makes the distance the independent variable. you can always use y=mx+b for these problems!!
Answer:
- 127.3
- 52.7
- 127.3
- 52.7
Step-by-step explanation:
Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).
52.7 + x = 180
x = 127.3
Best of Luck!
Answer:
Step-by-step explanation:
Given
---- proportion of watches with defects
--- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means:
So, the probability is represented as:
Solving (b): Calculate
Normal or Poisson: Normal distribution is characterized by 2 parameters and .
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
Calculate standard deviation
By continuity correction, we have:
So, we have:
Calculating , we have:
Calculate z score
So, we have:
Using the z score probability table, we have:
So, we have:
