The mean is 10
To find the mean you add up all of the numbers (70) and then divide it by how many number there are. so in this question there are 7 numbers. 70/7= 10
Answer:
The probability is 1/2 or 50%
Step-by-step explanation:
P(roll less than 4) = Probability of rolling less than 4
There are 3 numbers that are less than 4.
1, 2, 3, 4, 5, 6.
There is a total of 6 sides.
So,
3/6 simplified to 1/2 or 50%
$33.60. 20% of 40 is 8. 40 minus 8 is 32. 5% of 32 is 1.60, with a sum of 33.60, the total for the shirt.

Step-by-step explanation:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.

Answer: C) All real values of x such that 
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
