Answer:
D) 67.4°
Step-by-step explanation:
by observation, and noting that triangle PQR is a right triangle
sin R = opposite length / hypotenuse
in our case, the hypotenuse is PR = 13 and the length opposite form R is QP = 12
hence
sin R = opposite length / hypotenuse
sin R = 12/13
R = sin⁻¹ (12/13) = 67.4⁰
Answer:
we have
C = 1.5d
or
d=C/1.5
Step-by-step explanation:
when d is 12
C=1.5×12=18
when c=15
d=15/1.5=10
Answer:
C. x = 2
Step-by-step explanation:
The answer is b I got it right on my test
Find the median first. The middle of all the numbers.
5, 7, 8, 10, 11, 13, 14, 18, 27
11 is the median.
Then find the median of the upper quartile.
The upper quartile consists of numbers...
5, 7, 8, 10
Since it is an even set of numbers add the two in the middle and divided by two. So 7 plus 8= 15/2.
7.5 is your upper quartile.
