M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
Answer:
8861 : 9495
Step-by-step explanation:
Ratio of income in 2001 to 2003:
53,166 : 56,970
Then, you can simplify by dividing both sides by 6:
8,861 : 9,495
Can't simplify anymore, Therefore this is the answer!
8861 : 9495
Hope I helped! Have a good day :)
Answer:
(x) = x - 5
Step-by-step explanation:
Let y = f(x) and make x the subject
y = x + 5 ( subtract 5 from both sides )
y - 5 = x
Change y back into terms of x, thus
(x) = x - 5
Question: In the following questions, look at different ways to represent the relation given by the equation y = x2 - 1. The table below shows some values for the given equation. Find the values of a and b.
Answer:
a= 3
b= 0
Answer:
a) P(k≤11) = 0.021
b) P(k>23) = 0.213
c) P(11≤k≤23) = 0.777
P(11<k<23) = 0.699
d) P(15<k<25)=0.687
Step-by-step explanation:
a) What is the probability that the number of drivers will be at most 11?
We have to calculate P(k≤11)




b) What is the probability that the number of drivers will exceed 23?
We can write this as:




c) What is the probability that the number of drivers will be between 11 and 23, inclusive? What is the probability that the number of drivers will be strictly between 11 and 23?
Between 11 and 23 inclusive:

Between 11 and 23 exclusive:

d) What is the probability that the number of drivers will be within 2 standard deviations of the mean value?
The standard deviation is

Then, we have to calculate the probability of between 15 and 25 drivers approximately.
