A) Here's your table as far as I can determine. Start by filling in the given numbers. The rest is simple addition and subtraction.
B) 5/100 = 5% of respondents don't like either volleyball or soccer.
C) 20% dislike soccer; 55% dislike volleyball. It seems that there is a greater dislike for volleyball.
Answer:
-3 I think
Step-by-step explanation:
Plz mark brainliest
Answer:
i think is b
Step-by-step explanation:
because the equation 8x＜-48 means -48 greater than 8x so it if you choose a than i will become 8(6)＜-48 this is wrong because positif integer always is greater,zero also greater than negatif integer.So by comparing the another i think the answer is b.I hope it will help you and it is correct.
Answer:
N = 105/u
U = 105/n
Step-by-step explanation:
Let's solve for n.
un=(5)(21)
Step 1: Divide both sides by u.
nu/u = 105
un = 105/u
__________________________
Let's solve for u.
un=(5)(21)
Step 1: Divide both sides by n.
nu/n = 105/n
u = 105/n
Please include the instructions; I assume your job is to find the value of x.
<span>1/(x+1) - 1/(x+2) = 1/2 would better be written as
1 1 1
</span><span>-------- - ------------ = ----
x+1 x+2 2
Identify the LCD. It is (x+1)(x+2)(2). Mult. all 3 terms of the equation by this LCD:
2(x+2) - 2(x+1) = 2(x+1)(x+2)
We can factor out the 2 from all terms:
x+2 - x - 1 = x^2 + 3x + 2
Let's move all terms from the left to the right side:
0 = x^2 + 3x + 2 - x - 2 + x + 1
Then x^2 + 3x + 1 = 0. This is a quadratic with a=1, b=3 and c=1.
What is x?
-3 plus or minus sqrt( 9-4(1)(1) ) -3 plus or minus sqrt(5)
x = --------------------------------------------- = ---------------------------------
2 2
I rather expected to obtain an integer value for x.
Why don't you give this problem a try yourself? Suggestion: First mult. every term by 2. This will give you:
2 2
------- - ------- = 1 and this may be slightly easier to work with. Please
x+1 x+2 give it a try: try to find x that satisfies this equation.
Important: note that x cannot equal either -1 or -2.
