281.2 units³
volume of Prism: Base Area x Height
Here given:
Base Area: 38 units²
Height: 7.4 units
Solve for volume:
38 x 7.4
281.2 units³
Answer:
Write the equation (3 $3) + (2 $7) = total cost of five hours. (B)
Step-by-step explanation:
6x+2=2x-2
6x+2-2=2x-2-2
6x=2x-4
6x-2x=2x-4-2x
4x=-4
4x/4= -4/4
x= -1
hope this helps :)
Answer: Option D
![P=0.3079](https://tex.z-dn.net/?f=P%3D0.3079)
Step-by-step explanation:
We can use the binomial formula to solve this problem.
![P(X=x)=\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D%2Ap%5Ex%281-p%29%5E%7Bn-x%7D)
Where p is the probability of success, n is the sample size and x is the number of successes expected.
Note that in this case
(probability that a part is defective)
![n = 25](https://tex.z-dn.net/?f=n%20%3D%2025)
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
Then we calculate the probability
![P(X=1)=\frac{25!}{1!(25-1)!}*0.02^x(1-0.98)^{25-1}](https://tex.z-dn.net/?f=P%28X%3D1%29%3D%5Cfrac%7B25%21%7D%7B1%21%2825-1%29%21%7D%2A0.02%5Ex%281-0.98%29%5E%7B25-1%7D)
![P(1)=0.3079](https://tex.z-dn.net/?f=P%281%29%3D0.3079)
