Find the area of the triangle below
Step-by-step explanation:
I got 47.5 for this, not sure if its right though.
7
72√
14
142√
The value of x in the figure would be 14. Option 3.
To get x, we can use the following formula:
Sine 45 = opposite/hypotenuse
In this case:
opposite = 7√2
hypotenuse = x
Thus:
Sine 45 = 7√2/x
x = 7√2/sine 45
= 7√2/√2/2
= 7√2 x 2/√2
= 14
In other words, the value of x is 14.

Question
The times of all 15 year old who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and standard deviation Sigma = 1. 2 sec. What percentage of the runners have times less than 14. 4 sec?.
Answer:
A. 0.15%
Step-by-step explanation:
The times of all 15 year old who run a certain race are approximately normally distributed with a given mean as 18 sec and standard deviation as 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 the probability from z score table, we get
