Answer:
Step-by-step explanation:
45h + 75 = 210
45h = 135
h = 3 hours
25 - 4x = 15 - 2x + 10
-10 - 10
15 - 4x = 15 - 2x
-15 -15
-4x = - 2x
no solution
Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE
Answer:
The answer is 43% or 0.43
Step-by-step explanation:
Given:
Probability that person selected aged 35years or older is a smoker = 17.5%
Probability that person selected aged 35years or older is a female comma =25.5%
Solution:
a) Probability (35yrs or older is a smoker) + probability (35years or older is a female comma)
= 17.5% + 25.5%
= 43% 0r 0.43
b) No, it would not be unusual because it is by chance, it may and it may not.
