Answer:
20 out of 120 times
Step-by-step explanation:
As others have said, the general formula is:
expected successes = probability*number of trials
Perhaps an easier question: If you roll a die 6 times, how many 4s would you expect to get?
1, right? 1 out of every 6. That’s what 1/6 means.
If you roll a die 12 times, you expect 2. 2/12 = 1/6

ASAP I NEED HELP 26,244π cubic centimeters. Find the radius of the ball.
Answer:
r = 27 cm
Step-by-step explanation:
[tex]Volume \ of \ ball = \dfrac{4}{3}\pi r^{3}\\\\\\\dfrac{4}{3}\pi r^{3}= 26244\pi \\\\\\r^{3}=\dfrac{26244*\pi *3}{4*\pi }\\\\\\r^{3}= 6561*3\\\\r^{3} = 3*3*3*3*3*3*3*3*3\\\\\\r=\sqrt[3]{3*3*3*3*3*3*3*3*3}=3*3*3\\\\r = 27[/tex]

What is the name of the property illustrated below?
3(x+4)=(x+4)+3
a :associative property of addition
b :commutative property of addition
c: associative property of multiplication
d: commutative property of multiplication
Step-by-step explanation:
I think you made a mistake with the equation.
because that property, that you presented, did not exist.
but
3(x+4) = (x+4)3 exists
and it is the commutative property of multiplication (a×b = b×a).

There are 90 seats on a train. 63 of the seats are empty. What percentage of the seats on the train are empty?
Answer:
70%
Step-by-step explanation:
Explain why the square root of a number is defined to be equal to that number to the 1/2 power.
This is because of the law of indices which says:
[tex]\sqrt[x]{n}[/tex]= [tex]x^{\frac{1}{m} }[/tex]
So, if we have:
[tex]\sqrt{n}[/tex]
Then the following will be true because of this math law:
[tex]n^{\frac{1}{2} }[/tex]
Side note: The m value can be greater than n and or less than n, but if it is equal the m and n values cancel out.

Use the function f(x)=x^2+4x-5 and the coordinate plane. SHOW ALL WORK FOR EACH PART!
What are the values of a, b, and c? (3pts)
Does the parabola open up or down? How do you know? (2pts)
What is the maximum or minimum value? How do you know? (2pts)
What are the x-intercepts? (2pts)
What is the y-intercept? (1pt)
What is the vertex? (2pt)
9514 1404 393
Answer:
a) a=1, b=4, c=-5
b) opens up; a > 0
c) minimum = -9, the y-value of the vertex
d) x = -5, 1
e) y = -5, the value of c
f) (-2, -9)
Step-by-step explanation:
A graph drawn by a graphing calculator can answer all of these questions quickly and easily.
__
a) The values of 'a', 'b', and 'c' are the values of the coefficients of the terms in the function definition. They refer to the coefficients in the standard form:
f(x) = ax^2 +bx +c
f(x) = x^2 +4x -5 . . . . . . . your equation with a=1, b=4, c=-5
__
b) The parabola opens up. This is because the value of 'a' is greater than zero.
__
c) The minimum is the y-value of the vertex. When the function is written in vertex form it is ...
f(x) = (x -h)^2 +k . . . . . . . . . . . vertex (h, k)
Your function can be put into this form:
f(x) = x^2 + 4x +4 -5 -4 . . . . . . add and subtract 4 to complete the square
f(x) = (x +2)^2 -9 . . . . . . . . vertex form. The vertex is (-2, -9).
The y-value of the vertex is -9, the minimum value of the function.
__
d) Solving f(x) = 0, you get ...
(x +2)^2 -9 = 0
(x +2)^2 = 9 . . . . . . . . add 9
x +2 = ±√9 = ±3 . . . . . take the square root; next, subtract 2
x = -2 ±3 = {-5, 1} . . . . . the x-intercepts
__
e) The y-intercept is f(0) = c = -5.
__
f) The vertex was found in part (c) to be (-2, -9).

A line passes through the point (-6, -2) and has a slope of -5/2
Answer: y = -5/2 -17
Step-by-step explanation: First put the equation in point slope form
Y-y1 = m(x-x1)
y + 2 = -5/2(x+6) then simplify to slope int. form
Y= mx + b
Y = -5/2x-17
Answer:
y = (-5/2)x - 17
Step-by-step explanation:
Slope Intercept Formula:y = mx + b
m = slope
b = y-intercept
Plugin Information:
y = mx + b
Slope = -5/2
y = (-5/2)x + b [tex]\longmapsto\\[/tex] Input x and y values from given point
-2 = (-5/2)-6 + b
Simplify, Solve for b:-2 = (-5 * -6)/(2) + b
-2 = 30/2 + b
-2 = 15 + b
b = -2 - 15
b = -17
Rewrite Equation:y = mx + b
m = -5/2
b = -17
y = (-5/2)x - 17

Felicia wants to keep her bill under $55. A cell phone provider charges Felicia $50 per month for her plan plus $0.05 per minute of long-distance calls. Which graph correctly shows the number of long-distance minutes Felicia can use this month?
Answer:
.05x+50=55
100 minutes
Step-by-step explanation:
simplify
.05x=5 (subtract 50 on both sides)
5/.05=x
100=x
she can call for 100 minutes
Did you mention that multiplication is a shortcut for repeated addition?
Step-by-step explanation:
yes, in a similar way as division is a shortcut for repeated subtraction.
you do know, that you normally have to add the points win in a game, right ?
so, your score grows by 200 points each time you score.
that means
200
200
200
...
200
what do you think you do to get the total ? you add all the points.
you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.
but you did not have 200 hits, you only got 12 hits.
so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).
and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.
that is how multiplication works and helps with additions.
