Answer:
x=3
Step-by-step explanation:
We are given the equation

This can be rewritten as

Now using the quotient rule for logarithms we can combine these two

Next we can remove the log by using an inverse operation

Now we can solve for x

Answer: D. 0.9967
Step-by-step explanation: To solve this, you need to do the z-score formula with both numbers. So 30-22/2.5 = 3.2. On the z-score chart, that equals .9993. Hold onto that number. Then you do the same with 15. 15-22/2.5 = -2.8. On the z score chart, that equals .0026. Subtract those numbers. .9993 - .0026 = .9967. It's not as compacted as it looks <3
Answer:
x = 30°
The angles:
- 2x° = 60°
- 3x° = 90°
- x° = 30°
Step-by-step explanation:
Hello!
The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.
Solve the equation:
- 2x° + 3x° + x° = 180°
- 6x° = 180°
- x° = 30°
We can replace 30° for all the angles.
The measures are:
- 2(30°) = 60°
- 3(30°) = 90°
- 1(30°) = 30°
