Answer:
C: x = 5 and y = (5√3)/2
Step-by-step explanation:
Looking at the triangle, we can use trigonometric ratios to find x and y since it's a right angled triangle.
Thus;
(5/2)/x = sin 30
x = (5/2)/½
x = 5
Similarly, (5/2)/y = tan 30
tan 30 in surd form is 1/√3
Thus;
(5/2)/y = 1/√3
y = 5/2 × √3
y = (5√3)/2
Answer:
You can hold 188.19 or a rounded 188 pounds per cubic feet
Step-by-step explanation:
First we need to find the area which is 271
I found this using the formula 2(WL+HL+HW)
If you can fit 271 square feet then you need to divide that by 4 to find cubic feet.
if you do this you get 67.75 cubic feet
next divide 67.75 by 0.36
you get 188.19
Answer:
0.86 (Approx)
Step-by-step explanation:
Given:
n = 35
P = 55% = 0.55
Q = 1 - p = 0.45
Computation:
Standard deviation σ = √npq
Standard deviation σ = √(35)(.55)(.45)
Standard deviation σ = 2.9432
Mean μ = np = 35 x 0.55 = 19.25
p[(x-np)/ σ ]
P[z<1.04204]
= 0.86 (Approx)
B. congruent, im pretty sure
Answer:
k=6 and x=-11. Another way to say it is 6,11.
