The card one is 4/52 for kings but then 20/51 because you take a card the first time and you do not replace it.
The marbles is 1/4 chance. 10 green 10 not. For ball 1 it’s a 1/2 (50:50) chance of picking green. that’s reduce because you want to pick 2 green balls (25% chance)
Answer:
(x+7)(x-7)
The factors are -7 and 7
Step-by-step explanation:
Given the function x²-49, to find the factors, we will factorise the expressed using the different of two square.
If a and b are two numbers, then based on difference of two square;
a²-b² = (a+b)(a-b)
Applying this to the function in question
x²-49
= x²-7²
= (x+7)(x-7)
The factors can be gotten by equating the function to zero according to factor theorem.
(x+7)(x-7) = 0
x+7 = 0 and x-7 = 0
x = -7 and 7
Answer:
39.25
Step-by-step explanation:
Area of circle is pi(3.14) times r^2.
Semi means half
So 3.14 times 5^2 = 78.5
Its a semi ciricle so its 78.5/2 which is 39.25
Ok well, not technically yes, but jk's midpoint is (1,5) and ln is (5,3). So they're not the same. In this case in my opinion, it's no.
The point (-2, 5) is not included in the solution area
<h3>The graph of the inequalities</h3>
The system of inequalities is given as:
y > 5x + 5
y > -2x+1
See attachment for the graph.
Since the inequalities use the greater than symbol, then the lines of the inequalities would be a dotted line and the upper part would be shaded
<h3>The solution area</h3>
The point is given as:
(-2, 5)
The point (-2, 5) is not in the shaded area of the system of inequalities
Hence, the point is not included in the solution area
Mathematically, we have:
5 > 5 * -2 + 5 ⇒ 5 > -5 --- true
5 > -2 * -2 +1 ⇒ 5 > 5 --- false
Since both inequalities are not true, then the point is justified
