Answer:
∠ TUW = 127°
Step-by-step explanation:
∠ QRU and ∠ TUW are corresponding angles and are congruent , thus
∠ TUW = ∠ QRU = 127°
The percentage of the runners who have times less than 14.4 sec is 0.15%
The times of all 15-year old who run a certain race are approximately normally distributed with a given mean of 18 sec and a standard deviation of 1.2 sec.
We know that,
where,
X = raw score = 14.4
μ = mean = 18
σ = standard deviation = 1.2
Putting the values,
Finding the probability from the z score table, we get
P(z < -3) = 0.00135 = 0.135%

The median is 4 and the range is 5 the average should be 4.5
The median is where the middle is so if you count on either side until you get to the middle you have the median. The average is all the numbers added up divided by the number of numbers ( you might want to check me incase I typed it in wrong on my calculator. The range is just the highest- the lowest:)
