Answer:
456
Step-by-step explanation:
11.5 oz would be 2 standard deviations below the mean... z -score = -2 = .0228 (from Z-Score table)
22.8% of 2000 = 456
1. Y=X-4
2. Y=X*4
3. Y=X+3
4. Y=X/6
Answer:7.775
Step-by-step explanation:
So u do 130.05 ÷18 =7.225
Now u do 15 - 7.225 = 7.775
7.775 is the money she can still spend for them.
Also u could do 15 x 18 = 270
270 ÷ 2 = 135
The probability that will not rain today is: 85%
100% - 15% = 85%
The correct answer is A
Answer:

Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization

Now we take (x + 4) as a common factor

If we have an expression of the form
we know that this expression is equivalent to:

In this case

So:

Finally:

The solutions are:
