Z-score is given by the formula:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the z-score for the data set with mean 13 and standard deviation of 2.5 will be:
z=(10-13)/2.5
z=-1.2
These two angles are vertical angles. Vertical angles are congruent, so you have to make an equation.
2x + 29 = 9x - 13
7x = 42
x = 6 degrees
Answer:
Step-by-step explanation:
<u>As per similarity, the ratios of corresponding sides are same:</u>
- x/120 = 65/50
- x = 120*65/50
- x = 156 ft
Answer:
62
Step-by-step explanation:
To find the mean, add the numbers together and divide the sum by the total amount of numbers.
