Answer:
I think the answer is 8 rounding tho would be 10
Step-by-step explanation:
B=kt
constant is k
b=0.25t
constant of proprtionality is 0.25
Answer:
Step-by-step explanation:
finding PR ( public relations :D , not that PR , the PR on this triangle thingy )
use law of cosines, again
c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]
where
c=PR
a= 9
b = 22
C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°
they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math
then
PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
PR = sq rt [ 81 + 484 -203.9550777 ]
( notice that now it is a subtraction sign instead of a plus sign, this time? )
PR = sq rt [361.0449 ]
PR = 19.0011
to the nearest 10th
19.0 :)

Answer: D) 72</h3>
======================================
Work Shown:
Angle PQR = (far arc - near arc)/2
2x+72 = ( (2x+252) - (2x+108) )/2
2x+72 = 144/2
2x+72 = 72
2x = 72-72
2x = 0
x = 0/2
x = 0
-------------
Angle PQR = 2x+72
Angle PQR = 2(0)+72
Angle PQR = 72 degrees
Answer:
Each value (1 to 6) has exactly the same probability of being rolled.
Step-by-step explanation:
Given
Rolls: 10
Outcome: 5 5 1 3 2 1 5 6 5 1
Required
Which is true about the next 10 rolls
In the roll of a fair die (as stated in the question), each face has equal probability of being the outcome of individual rolls.
This implies that options (a), (b) and (c) are not true because they do not support the above statement,
<em>Hence, (d) is correct</em>
