Answer:
400%
Step-by-step explanation:
We can write a percent proportion:
600/x = 150/100
a:b = c:d
a and d are linked and b and c are linked. So if a is missing, you would do (b*c)/d to get a, if b was missing, you would do (a*d)/c to get b, etc.
So over here we do
(600*100)/150 = 60,000/150 = 400, so x = 400, so that means it's 400% of 150
We can also use benchmark fractions which I find much easier:
100% of 150 is 150.
So 200% of 150 is 300
So 300% of 150 is 450
And 400% of 140 is 600
Every time it increases by 100%, it also increases by 150 on the other side, which makes sense
Let me know if you have any questions.
Answer:
D: 1/35
Step-by-step explanation:
First, you have to know how many marbles there are, and if you count them all up there are 15 marbles in total. Next, there are 3 blue marbles, so you would put the fraction as 3/15, or simplified to 1/5. Now, if you don't replace that blue marble, you now only have 14 marbles, and there are 2 yellow, which means you have a 2/14 chance of drawing a yellow marble, simplified to 1/7. But because there are two parts of the problem you are going to multiply 1/5 by 1/7 to get 1/35, which is your answer.
Answer:
24.5
Step-by-step explanation:
The mean is calculated as
mean =
The consecutive terms in the sequence have a common difference d
d = 7 - 2 = 12 - 7 = 17 - 12 = 5
This indicates the sequence is arithmetic with sum to n terms
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 5 , thus
= [ (2 × 2) + (9 × 5) ]
= 5(4 + 45)
= 5 × 49 = 245 , then
mean = = 24.5
No
if you solve the equation
2x - 3 = 9
2x = 9 + 3
2x = 12
x =12/2
x =6
answer is B (second choice)
