150. 1:4. 120:30. 120-30=90
Answer:
A. 5 : 3
Step-by-step explanation:
Number of blue cups : Number of red cups
10 : 6
Divide to the lowest terms
10 ÷ 2 : 6 ÷2
5 : 3
<span>We simplify the equation to the form, which is simple to understand
<span>4x+8-2x=20
We move all terms containing x to the left and all other terms to the right.
<span>+4x-2x=+20-8
We simplify left and right side of the equation.
<span>+2x=+12
We divide both sides of the equation by 2 to get x.
<span>x=6</span></span></span></span></span>
Answer:
Likely
Step-by-step explanation:
The probability of occurrence of a certain event Given as 95% has a high probability figure and hence such event is LIKELY to occur. We cannot class this probability percentage as certain because, an event which is certain to occur who'll have a probability percentage of 100% or a value of 1. Therefore, a probability percentage of 95% occurrence still has 5% Chace of not happening, hence it is only very likely to occur. Hence, the phrase which best describes the probability of an event with 95% probability happening is LIKELY.
Answer:
So average of a set of values is the sum of given values divided by the number of values
So, in this case the given values are 12, 9 , 4 , 8 ,7 and x (letting the 6th friend's time be x)
so the average will be:
(12 + 9 + 4 + 8 + 7 + x)/6 = 9
40 + x = 54
x = 54 - 40
x = 14 hours
