Answer:
x = 12
Step-by-step explanation:
Triangle DGH is isosceles with base angles at D and G. The external angle 134° at H is the sum of those two base angles, so we have ...
2(5x+7) = 134
5x +7 = 67 . . . . . divide by 2
5x = 60 . . . . . . . subtract 7
x = 12 . . . . . . . . divide by 5
Answer:
0.0000
Step-by-step explanation:
Given that a die is rolled 360 times. Let say that you want to use normal approximation to find the probability that the number of 4 was rolled exactly 100 times.
Here we know that getting 4 is binomial with p = 1/6 and n =360
By approximating to normal after checking conditions are satisfied we have
X = no of fours obtained is normal
with mean = 
and variance = 
Std dev = 7.072
X is N(60, 7.072)
For finding out prob x=100 we have to do continuity correction as

Step-by-step explanation:
previous =£400
present=£504
percentage=(£504-£400)/£504*100
=104/£504*100
=20.63%
Answer:
Considering the whole book as 100%, there’s 30% left.
Then, 30% of 230 = 0,3*230 = 69 pages.
