Which is more reliable, theoretical probability or experimental probability?Why?
Answer:
Theoretical probability is a calculated value whereas experimental is an observed value. Theoretical is more reliable because it is usually not subject to all the testing failures that are possible. Experimental probability is only used in practice or when there isn't any theory.
Both are useful, but theoretical probability is more reliable because it has been studied and matured, so it is more foolproof than experiments.
What is x if one and is 123 and the other is 3x on a straight line
Answer:
m24=123, mZ1=2x, mZ2=x+42. 123=3x+42. X=27. 193.
Step-by-step explanation:
The formula for volume of this rectangular prism is:
V=2x(exponent is 3) +17x (exponent is 2) +46x
use adjacent angles to solve for X
Answer:
69 degrees!
Step-by-step explanation:
Angle MKL = 180 - 146 = 34 (Angles on a straight line add up to 180)
Angle x = 180 - 77- 34 = 69 (Angles in a triangle add up to 180)

Add all the numbers in the teen section to find how many teens visited.
If you put teens over whole it will give you the fraction 86/758
If you divide 86 by 758 you will get 0.11345646438 .
Move the decimal two places to the right and round to get the percent 11.35.
A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in dollars, per fluid ounce between the two brands?
Answer:
$0.02
Step-by-step explanation:
Brand a
1.28 ÷ 8 = 0.16 per ounce
Brand b
1.68 ÷ 12 = 0.14 per ounce
0.16 - 0.14 = 0.02
Book club A charges $20 for membership and $2 per book rental. Book club B charges $10 for membership and $3 per book rental. For how many movie rentals will the cost be the same at both book clubs? What does that cost?
Given:
Book club A charges $20 for membership and $2 per book rental.
Book club B charges $10 for membership and $3 per book rental.
To find:
The number of books for which the cost be the same at both book clubs.
Solution:
Let x be the number of books.
Book club A charges $20 for membership and $2 per book rental. So, the total cost is
[tex]C_1=20+2x[/tex] ...(i)
Book club B charges $10 for membership and $3 per book rental. So, the total cost is
[tex]C_2=10+3x[/tex] ...(ii)
Equating (i) and (ii), we get
[tex]10+3x=20+2x[/tex]
[tex]3x-2x=20-10[/tex]
[tex]x=10[/tex]
The total cost is
[tex]C_1=20+2(10)[/tex]
[tex]C_1=20+20[/tex]
[tex]C_1=40[/tex]
Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
May someone answer these 4 questions for me? Find the area
What is the equation of the graph below?
А
y = 2(x + 4)2 – 2
B
y = (x – 4)2 – 2
C y = 2(x - 4)2 – 2
D
y = 2(x – 4)2 + 4
Answer:
f(x) = 1(x - 4)^2 - 2
Step-by-step explanation:
Recall that the vertex form of the equation of a parabola is
f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.
Looking carefully at the graph, we see that h must be 4 and k must be -2.
Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)
SOMEONE PLEASE ANSWER QUICK IM STUCK ON THIS ONE Factor 4n^2+12n.
What is the median?
A(18
B(27
C(33.2
D(34.5
Answer: 34.5
Step-by-step explanation:
First, write out all of the numbers from least to greatest.
which is (18,20,26,34,34,35,38,40,42,45)
Second, choose the number in the middle of the set of numbers you wrote out from least to greatest. (There are TWO numbers in this case, which are 34 and 35)
Lastly, since there are two numbers you add them both together and then divide by 2. (34+35=69 , 69 divided by 2 = 34.5)
What is the mean?
-9 -9 -3 -6 -7
Answer:
-6.8
Step-by-step explanation:
To find the mean, you add all the numbers together, then divide that number by the amount of numbers there were, so:
-9 + -9 + -3 + -6 + -7 = -34
-34/5 = -6.8

Thank you
Answer:
Step-by-step explanation:
Using the same proportion as the previous question
11/x = x / 8 Cross multiply
x^2 = 88 Factor 88 into at least 1 perfect square and something
x^2 = 4 * 22 Take the square root of both sides
x = sqrt(4 * 22)
x = 2*sqrt(22)
