Answer: 25%
Step-by-step explanation:
A coin has Head and tail
Thd likelihood that he will make his next two penalty kicks is synonymous to having head and head
Which is 1/2 × 1/2 = 1/4
Converting this to percentages gives 1/4 × 100 = 25%
Answer:
Step-by-step explanation:
The value with the exponent is the "multiplier". It is 0.05.
This value is less than 1, so the function represents <em>decay</em>.
The initial value is the number that multiplies the exponential term. It is the value of A when t=0: 250.
- original amount: 250
- growth or decay: decay
- multiplier: 0.05
Answer:

Step-by-step explanation:
Given
x 2 4 6 8
y 1 -2 -5 -8
Required
Determine the slope
First, pick any two corresponding x and y values.


The slope (m) is then calculated using:

Substitute in, the x and y values




Divide numerator and denominator by 3


<em>Hence, the slope is -3/2</em>
You're question asks why the given mixed numbers are equal.
In fact, they're equal.
Lets make it easier for you to understand:
8 4/3 has a improper fraction "4/3", that fraction is over 1 whole.
You could look at 8 4/3 as:
8 + 3/3 + 1/3
The 3/3 turns into 1:
8 + 1 + 1/3
9 + 1/3
9 1/3
You would see that it turns into 9 1/3, therefore they are equal.
Answer:
14.14
Step-by-step explanation:
Recall :
The sides of a square are always equal ;
Since all sides are equal, the the diagonal of the square will be :
XZ² = XY² + WX²
XZ² = 20² + 20²
XZ² = 400 + 400
XZ² = 800
XZ = √800
XZ = 28.28
WY = XZ
WV = 1/2 WY
WV = 1/2 * 28.28
WV = 14.14
