7. A battery manufacturer makes batteries that have a failure rate of .015. That is, 15 out of each 1,000 batteries are defectiv
azamat
The answer to this probability question is .86 or 86%. The probability that a batch of 10,000 batteries will contain at least 175 defective batteries is  86 percent. I calculated the failure rate of 10,000 batteries (10k*.015) and yielded 150, meaning there will be 150 batteries that will be defective in a set of 10,000. Then i divided 150 by 175 to get the probability.

Help!! Find the area of the triangle.
grigory [225]

Answer:

Area = 60.0 units²

Step-by-step explanation:

First, let's find the height of the triangle using Pythagorean Theorem:

Height = √(11² - 8²)

= √57

Height = 7.5 (nearest tenth)

✔️Find the area:

Area = ½*base*height

Base = 2*8 = 16

Height = 7.5

Plug in the values

Area = ½*16*7.5

Area = 60.0 units² (nearest tenth)
