Answer:

z^{2} +\frac{1}{2} +11z

Step-by-step explanation:

→ Minus the z² terms

1\frac{1}{2} z^{2} -\frac{1}{2}  z^{2}=1 z^{2}

→ Minus the whole numbers

3\frac{1}{2} -3=\frac{1}{2}

→ Add the z terms

11z

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 2
Anton [14]
Well , the diameter means a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. The area means what the extent or measurement of a surface or piece of land. So area means inside so all you need to do is  just to divide each side by knowing what 20/4 is and that = 5 meters

The table shows the outputs, y, for different inputs, x:
ASHA 777 [7]
Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.

Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.

Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>

Divide 50 by half and add 20 and <br> multiply by 2
aivan3 [116]

The value of the expression will be equal to 145.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that make an expression for divide 50 by half and add 20 and multiply by 2.

The expression will be solved as below,

E = 50/2 + 25 x 2 + 50 + 20

Solve the above expression by PEMDAS,

E = 25 + 50 + 70

E = 145

If A and B are independent events and P(A) and P(B) are both greater than 1/2
elixir [45]

Answer:

P(A and B) is greater than 1 is never happened ⇒ C

Step-by-step explanation:

Two events are independent if the result of the second event is not  affected by the result of the first event

If A and B are independent events, the probability of both events  is the product of the probabilities of the both events  P (A and B) = P(A) · P(B)

∵ The probability of any event is less than 1

∵ P(A) < 1

∵ P(A) > \frac{1}{2}

- That means P(A) is greater than half and less than 1

∴ \frac{1}{2} < P(A) < 1

∵ P(B) < 1

∵ P(B) > \frac{1}{2}

- That means P(B) is greater than half and less than 1

∴ \frac{1}{2} < P(B) < 1

∵ P(A and B) = P(A) . P(B)

- Remember the product of any fractions less than 1 is less than 1

∴ \frac{1}{4} < P(A) . P(B) < 1

- That means any expression equals to P(A) . P(B) must be greater

   than \frac{1}{4} and less than 1

∴ \frac{1}{4} < P(A and B) < 1

∴ P(A and B) is greater than 1 is never happened
