Answer:
0.4 or 0.40
Step-by-step explanation:
There are 10 total numbers. 4 of them are in set B.
So, 4/10 are in set B.
The probability is 0.4 because 4 divided by 10 is 0.4.
Answer:
½
Step-by-step explanation:
A coefficient is any number that comes before a variable and is multiplies that variable.
In the equation given, the term involving the variable x is x³/2. Therefore, the coefficient of x³/2 would be ½.
i.e. ½ × x³
First, make your ratios into fractions.
You have 2/5 = 3/4.
Now, in your calculator, divide 2 by 5. You get 0.4
Then in your calculator, divide 3 by 4. You get 0.75
0.4 does not equal 0.75
Therefore, there is no solution/they are not equivalent.
Y=x²+8x+14
to make a square, if a is 1, add (half of b)²
in this case, a=1, b=8, half of 8 is 4
y=x²+8x+4²-4²+14
y=(x+4)²-16+14
y=(x+4)²-2
B is the answer.
another way to do it:
the vertex is at x=-b/2a=-8/2*1=-4
when x=-4, y=(-4)²+8(-4)+14=-2
so the equation is y=[x-(-4)]²-2, which is y=(x+4)²-2, the same answer B
I believe the answer is 1.2
