Answer:
probability is usually what is EXPECTED to happen not guaranteed to happen.
We can see that the statement that says probability can be used to predict the result of an activity is incorrect because:
Probability is actually used to determine an expected outcome of events.

Answer:
3 units
Step-by-step explanation:
By intersecting chords theorem:
[tex] AE \times EB = CE \times ED[/tex]
[tex] \therefore 3 \times 4= x \times (x+1)[/tex]
[tex] \therefore 12= x^2 +x[/tex]
[tex] \therefore x^2 +x-12=0[/tex]
[tex] \therefore x^2 +4x-3x-12=0[/tex]
[tex] \therefore x(x +4)-3(x+4)=0[/tex]
[tex] \therefore (x +4)(x-3)=0[/tex]
[tex] \therefore (x +4)=0, \: (x-3)=0[/tex]
[tex] \therefore x=-4, \: x=3[/tex]
Since, the value of x can not be negative.
[tex] \therefore x\neq - 4[/tex]
[tex] \implies x = 3[/tex]
[tex] \implies CE = 3[/tex]
1) Em uma rua há duas casas e em cada casa há dois galinheiros. Em cada galinheiro há dois cercados, em cada, há duas galinhas, e cada galinha tem dois pintinhos. Qual o total de pintinhos dessas casas?Pergunta sem título *
Answer:
Hay 32 pollitos en total.
Step-by-step explanation:
Para contestar a la pregunta planteada se debe realizar el siguiente razonamiento matemático:
Casas = 2
Gallineros = 2
Cercados = 2
Gallinas = 2
Pollitos = 2
2 x 2 x 2 x 2 x 2 = X
4 x 2 x 2 x 2 = X
8 x 2 x 2 = X
16 x 2 = X
32 = X
Por lo tanto, hay 32 pollitos en total.

Use the Pythagorean Theorem to find the missing length and then round the
result to the nearest tenth.
b = 2, c = 3
a =
Answer:
A=2.2
Step-by-step explanation:
PYTHAGOREAN THEOREM:
a^2+b^2=c^2
STEP 1:
Lets put in the given number into the Theorem.
x^2+ 2^2= 3^2
I put x in the "a" place because there is no Number that goes into there, so we put in a variable.
STEP 2:
We find the numbers, which are
x^2+4=9
STEP 3:
We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)
After subtracting from both sides we have
x^2=5
STEP 4:
Once we have that, we have to find the square root of 5 which is 2.23606798
STEP 5:
Since you say to round to the nearest tenth, we get 2.2
TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex] Which is the same as 2.23606798.

I: base length
w: base width
h: pyramid height
Now, put the values in the formula to form an equation and solve it.
V = l * w * h / 3
= 6.3 * 2.4 * 3.6 / 3
= 18.144 mm3

Answer:
[tex]Domain =\{0,4,7,10,13\}[/tex]
[tex]Range = \{-5\}[/tex]
[tex]y = -5[/tex] --- function
Step-by-step explanation:
Given

Solving (a): The domain
The x values represent the domain.
Hence, the domain is:
[tex]Domain =\{0,4,7,10,13\}[/tex]
Solving (b): The range
The y values represent the range
Hence, the range is:
[tex]Range = \{-5\}[/tex]
Solving (c): The function
By observation, we can see that for all values of x the value of y remains unchanged (-5)
Hence, the function is:

Sum of place value and face value of 5 in 75897 is
Given:
The number is 75897.
To find:
The sum of place value and face value of 5 in the given number.
Solution:
The given number is:
75897
The face value is 5 is always 5.
The number of is 5 on thousands place. So, the place value of 5 is:
[tex]5\times 1000=5000[/tex]
The sum of place value and face value of 5 in the given number is:

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?
Answer:
$86.36
Step-by-step explanation:
Tax: 7%, or 0.07
Tip: 20%, or 0.2
Substitute the values:
Tip: 68 * 0.07 = 4.76
Tip: 68 * 0.2 = 13.6
Just the meal cost: 1 * 68 = 68
Add these all together
4.76 + 13.6 + 68 = 86.36
Thus, the total cost of the meal would be $86.36
After solving the system x+2y=10 and x-2y=2. What is the sum of x+y equal to?

2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
Answer:
6 + 2 = 8
Step-by-step explanation:
[tex]x + 2y = 10 \\ + \\ x - 2y = 2 \\ = \\ 2x = 12 \\ x = 6 \\ 6 + 2y = 10 \\ 2y = 4 \\ y = 2 \\ x + y = 6 + 2 = 8[/tex]

1. Find the five-number summary of each data set. Then construct box-and-whisker plots of the data sets. Draw both plots above the same number line. Label the plots with the girls’ names.
Answer:
hope this helps sweetie :)
Step-by-step explanation: So first what you want to do find the data sets. You can do that by crossing out the numbers to find the median which would be in the very middle. Then draw the box and whisker plot, and boxes around each number. this should give you everything you need to draw the number line and label the plots.
Answer:
Sherelle: Venita:
minimum = 26 minimum = 44
maximum = 85 maximum = 79
First Q. = 60.5. First Q. = 53
Third Q. = 74.75 First Q. = 72.25
Median = 69.5. Median = 63.5
