Answer:
P(red marble) = 6÷15
Step-by-step explanation:
First, we add all of it we get 15.
Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.
Here the favorable outcomes to red is 6,and the total outcome is 15.
So it is 6÷15.
Now we took one marble. And kept it away.
Now the total number of outcomes are 15-1=14
Now the favorable outcomes for green is 7,snd total outcomes are 14.
So the probability is 7÷14.
Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.

Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5

Answer: 53 points
Step-by-step explanation:
Let the number of points gotten by Kate be represented by x.
Since we are given the information that Kevin got 52 points which was 54 points less than 2 times that of kates points. This can be formed into an equation as:
(2 × x) - 54 = 52
2x - 54 = 52
2x = 52 + 54
2x = 106
x = 106/2
x = 53
Kate got 53 points
