We can write a proportion between short and long legs:

Solving for k yields

Answer:
c) -1.75°
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 0, standard deviation of 1:
This means that 
Find the reading that separates the bottom 4% from the others.
This is the 4th percentile, which is X when Z has a p-value of 0.04, so X when Z = -1.75.




The correct answer is given by option c.
1 quart= 2 pints so 31 pints = 15.5 quarts so 15.5+13=23.5-20= 3.5 left hope this explains it better!!
4/3 ig I kept I did y2-y1 division
x2-x1 division
Answer:
x=14
Step-by-step explanation:
45 = 3 (x + 1)
Distribute the 3 to both terms in the parentheses
45 = 3x +3
Subtract 3 from each side
45-3 = 3x+3-3
42 = 3x
Divide each side by 3
42/3 = 3x/3
14 =x
