Answer:
Value for x cannot be deduced
Step-by-step explanation:
To solve this question we will have to open the bracket first...we will solve using bodmas rule
1/2(10x+5)-3/2=2x+6+3x
Open the bracket
5x+5/2-3/2=2x+6+3x
Let's collect the like terms
5x-2x-3x=6-5/2+3/2
Lcm for the right side is 2
0=12-5+3/2
0=10/2
0=5
Therefore the value for x cannot be deduced due to the fact that x has been cancelled when solving
The correct answer is 67 to the third power
The dot product of two vectors is defined as the sum of the multiplication of each of its components.
We have then:
B = [2 8 .6 3]
A = [3 0 2 -1]
Making the product point:
BA = [2 8 .6 3] [3 0 2 -1]
BA = (2 * 3) + (8 * 0) + (0.6 * 2) + (3 * (- 1))
BA = 4.2
Answer
BA = 4.2
If you have $8 and something’s cost $3 you will be getting $5 dollars back
Answer:
2.86%
Step-by-step explanation:
assuming there is no replacement
There is a total of 6 envelopes
Since the question is asking for red, then green, then red, order is very important
The probability of a red is 3/7
Since we have selected 1 envelope, there are only 6 total envelopes left so the probability of a green is 1/6
Then we need a red again
Since we have selected 2 envelopes, one of which is red, there are only 5 total envelopes and 2 red envelopes so the probability of a red is 2/5
Now we multiply all of these so 3/7x1/6x2/5 = .02857142857
To find the percentage, you multiply by 100 so 2.857142857
Im pretty sure they want you to estimate it so 2.86% is what I would put but it depends on your teacher
