Answer:
Anle at B
b = 56.25°
Step-by-step explanation:
Triangle ABC is a right angle triangle. we are required to look for the angle at B
To do that we have one side of the triangle missing and we'd look for it first.
Let's side AC = c
AB = a
BC = b
c²=a² - b²
C² = 9² -5²
C² = 81 - 25
C² = 56
C = √56
For angle at B
√56/sinb = 9/sin90
Sin 90 = 1
Sinb = √56/9
b = sin^-1 (√56/9)
b = 56.251°
To the nearest hundredth
b = 56.25°
Answer: Q1 = 7.5
Q3 = 14
Step-by-step explanation:
Q1 means the lower quartile of a group of numbers and Q3 means the upper quartile. Once the median of such group of numbers are established then the the median of the lower set of numbers is the Q1 and the median of the upper set of numbers is the Q3.
We're given the data:
6,7,8,9, 11, 13, 14, 14, 18
Median of the general set of numbers = 11.
Q1= median of 6,7,8,9 = (7+8)/2 = 7.5
Q3 = median of 13,14,14,18 = (14+14)/2 = 14
