Answer:
Stuck In same question
Step-by-step explanation:
It would be 50% because it’s equally likely
-1 (-12 - 9i) + 4i (-12 - 9i)
= 12 + 9i + -48i + 9i^2
= 9i^2 + 39i + 12
Answer:
58 units squared
Step-by-step explanation:
**I'm doing the question with the 7 by 3 triangle in the picture, not 777 by 333**
Pythagorean Theorem: , where c is the length of the hypotenuse.
The given sides are legs, therefore,
c is also one of the sides of the square. A square's area is one of the sides' lengths squared, so:
Since the standard deviation for the population is known, the z-distribution is used.
<h3>When to use the t-distribution and the z-distribution?</h3>
- If the population standard deviation is known, the z-distribution is used.
- If the population standard deviation is not known, only the sample standard deviation, the t-distribution is used.
In this problem, the <u>standard deviation for the population is known</u>, hence the z-distribution is used.
