Answer:
0.006369
Step-by-step explanation:
Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.
By mere guessing p = probability for a right answer = 1/5 =0.20
There are two outcomes and each question is independent of the other.
X no of questions right is Bin (10,0.20)
the probability that the student will pass the test
= prob of getting more than 60%
=![P(X\geq 6)](https://tex.z-dn.net/?f=P%28X%5Cgeq%206%29)
=0.006369
Answer:
2nd choice: The ball first bounced up to the height of 2 meters, and then falls 2 meters towards the ground
Step-by-step explanation:
1. Lamar sold 3 boxes of cookies.
2. Anna sold 4 boxes of cookies.
3. They each sold $24 worth of cookies.
1.64 million rounded to the nearest million is 2 million.
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
![\frac{y_{2} - y_{1}}{x_{2} - x_{1}}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%20)
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
![\frac{z-c[tex]y-w= \frac{z-x}{y-w} (x-c)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz-c%5Btex%5Dy-w%3D%20%5Cfrac%7Bz-x%7D%7By-w%7D%20%28x-c%29)
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29)
Now we can substitute
m for the slope, and use any points to plug in
![x_{1}](https://tex.z-dn.net/?f=x_%7B1%7D)
and
![y_{1}](https://tex.z-dn.net/?f=y_%7B1%7D)
.
Hope this helps! :^)
