Answer:
5) x = 24
6) x = 48
Step-by-step explanation:
I'd be glad to help :)
For question 5, we know that 62 and the unknown angle is a straight angle, so 62+y = 180. y = 118. We also know all the angles in a triangle add up to 180, so x+(x+14)+118 = 180. Therefore, 2x+132 = 180. We now know that 2x = 48, so x = 24 for question 5.
For question 6, We know that because the line is divided up, (x+35) can be moved down a line, so (2x+1)+(x+35) = 180, so 3x+36 = 180. We now know that x = 48 for question 6
72% as a fraction is 18/25.
Change 72% into a decimal, which is 0.75.
Then change the decimal into a fraction, 72/100.
Last step is to simplify 72/100 in its lowest form which gets us 18/25.

Deviation is how much data in the set differs from the mean or average of the set. This is true.
Answer:
9
Step-by-step explanation:
take the x and drop it down after that the - needs to become the postive with takes multiple and so then after tyat it needs to add the extra 1 bc if the 1
Answer:
P(x ≤ 5 ) = 0.9707
P ( x ≥ 6) = 0.0293
Step-by-step explanation:
The probability of a binomial mass distribution can be expressed with the formula:
where;
n = 8 and π = 0.36
For x = 5
The probability 
to 4 decimal places
b. x ≤ 5
The probability of P ( x ≤ 5)
P(x ≤ 5 ) = 0.0281+0.1267+0.2494+0.2805+0.1972+0.0888
P(x ≤ 5 ) = 0.9707
c. x ≥ 6
The probability of P ( x ≥ 6) = 1 - P( x ≤ 5 )
P ( x ≥ 6) = 1 - 0.9707
P ( x ≥ 6) = 0.0293
