If you draw this triangle on a graph as described, tan theta is -4(square root)33/33
Answer:
7 Celsius
Step-by-step explanation:
Initial temperature at 12pm is 1 Celsius.
Rises by 6 (add by 6).
To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28
<span>2 to 3 students will get greater than 20 measurement</span>
