Answer:
P(.6666...) or P(2/3)
Step-by-step explanation:
We know we have one single event with 3 outcomes. We can figure that 5 is the only other odd number not 1-3, so that means we have 3+1 outcomes
Ok, so no we know we have 1 singular event with 3+1 possible outcomes
This means the probability is 4/6, due to a normal die having 6 faces.
Therefore, the probability is 4/6, 2/3, or .666666......
Please note that I have not done P&S for over 1 year now and I learned it in geometry, but don't be discouraged as I googled how to do this, but if I wrong, tell me.
The Probability of obtaining a number less than 3 or odd when a standard number cube is tossed is 2/3.
In probability theory, the question is asking for the possibility of tossing a number cube and landing on a number less than 3 or an odd number.
In a standard number cube which is a die, we have six numbers (1, 2, 3, 4, 5, 6).
Numbers less than 3 are 1 and 2.
The odd numbers are 1, 3 and 5.
However, 1 is common to both cases, so we add the total unique outcomes which are 1, 2, 3, and 5.
So, we have four favorable outcomes.
To find the probability, you calculate the ratio of the favorable outcomes to the total possible outcomes.
In this case, it will be 4 favorable numbers against 6 possible numbers altogether.
Hence, P(less than 3 or odd) is 4/6 which can be simplified to 2/3.

Melanie paid $42.50 for 3 adult tickets and 2 student tickets at Theater A. Drew paid $47 for 4 student tickets and 2 adult tickets at Theater A. Theater B charges $9 for each adult ticket and $7 for each student ticket.
Which of the following statements is TRUE?
A
The price for each adult ticket is the same at both theaters
B
The price for each student ticket is the same at both theaters.
C
The price of an adult ticket at Theater A is $0.50 less than the price of an adult ticket at Theater B.
D
The price of a student ticket at Theater B is $0.50 less than the price of a student ticket at Theater A.
Answer:
B. The price for each student ticket is the same at both theaters
Correct Option is B.
System of Linear equations:
A system of linear equations is a set of equations which are satisfied by the same set of variables.
Ex : 2x - y = 12 , x - 2y = 48
Here,
Let's take adult ticket price in theatre A = x
And the student ticket price in theatre A = y
So, (Given), 3x + 2y = $42.50 (Melanie paid)
=> 2y = $42.50 - 3x --(1)
Also given, 2x + 4y = $47 (Drew paid)
=> 4y = $47 - 2x
2(2y) = $47 - 2x
Now, substitute 2y value from eq-(1), we get
2($42.50 - 3x) = $47 - 2x
$85 - 6x = $47 - 2x
=> $85 - $47 = 6x - 2x
=> $38 = 4x
=> x = ($38)/4 => 9.5
Substitute x value in eq-(1), we get
2y = $42.50 - 3(9.5) => y = $7.
In the given options only Option B is the correct answer.

A group of friends went to play minigolf at Adventureland. Anna's score was 262 putts, Daniela's score was 313 putts, Luiza's score was 393 putts, and Vera's score was 323 putts. Find the mean absolute deviation (MAD) of the data set.
Answer:
35.25
Step-by-step explanation:
There are 4 data:
262, 313, 393, and 323
The formula for MAD (mean absolute deviation) = [tex]\frac{SUM(|x_{i}-XBar|)}{n}[/tex]
Where x_i are the each individual values (stated)
XBar is the average value
n is the number of data
First, let's find XBar, or the average. We add up all the 4 numbers and divide by 4 to get:
XBar = (262+313+393+323)/4=322.75
Now, let's calculate MAD:
MAD = [tex]\frac{|262-322.75|+|313-322.75|+|393-322.75|+|323-322.75|}{4}\\=35.25[/tex]

By showing that 0.20 is greater than 0.18 by doing 0.20-0.18 which gives a positive 0.02, thich means that its greater.
0.2 is greater than 0.18.
What inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
We have to Compare 0.2 and 0.18.
First we have two digits in 0.18 after decimal.
Then, make 0.2 with two digits after decimal as 0.20.
Now, compare the after decimal value
20 > 18

Find the future value and interest earned if $8706.54 is invested for 8 years at 6%
Answer:
Flat 12,885.68
Compound 13,876.90
Step-by-step explanation:
Flat rate (6% of only the amount you invested originally per year (based on investment) -
(8706.54*.06)*8+8706.54=12885.68 (rounded)
Compound interest (6% interest on total money earned per year(based on amount invested previous year).)
(((((((8706.54*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)=13,876.90
The future value of the investment is $13876.90 and the interest earned is $5170.36.
To solve this problemWe can use the following formulas:
Future value = [tex]Principal * (1 + Interest rate)^N^u^m^b^e^r ^o^f^ y^e^a^r^s[/tex]
Interest earned = Future value - Principal
Substituting the known values into the formulas, we get:
Future value =[tex]$8706.54 * (1 + 0.06)^8 = $13876.90[/tex]
Interest earned = $13876.90 - $8706.54 = $5170.36

What is the end behavior of the graph of f(x) = x5 – 8x4 + 16x3?
Answer: B.) f(x) => -∞ as x => -∞; f(x) => +∞ as x => +∞
The graph touches, but does not cross, the x–axis at x =__
The graph of the function crosses the x–axis at x = ___
Answer:
Step-by-step explanation:
f(x) = x⁵ – 8x⁴ + 16x³
As x approaches +∞, the highest term, x⁵, approaches +∞.
As x approaches -∞, x⁵ approaches -∞ (a negative number raised to an odd exponent is also negative).
Now let's factor:
f(x) = x³ (x² – 8x + 16)
f(x) = x³ (x – 4)²
f(x) has roots at x=0 and x=4. x=4 is a repeated root (because it's squared), so the graph touches the x-axis but does not cross at x=4.
The graph crosses the x-axis at x=0.

graph of which exponential function passes through the points (0,4) and (1,24)?
Answer:
see explanation
Step-by-step explanation:
The exponential function is of the form
y = a [tex]b^{x}[/tex]
Substitute the given points into the equation to find a and b
Using (0, 4), then
4 = a[tex]b^{0}[/tex] ⇒ a = 4
Using (1, 24), then
24 = 4 [tex]b^{1}[/tex] ⇒ b = 6
Exponential function is
y = 4 × [tex]6^{x}[/tex]
The equation of the exponential function that passes through the points (0,4) and (1,24) is y = 4(6)^x.
Explanation:To find the equation of the exponential function that passes through the points (0,4) and (1,24), we can use the general form of an exponential function: y = ab^x, where a is the initial value and b is the growth/decay factor.
Using the point (0,4), we plug in x=0 and y=4 to get the equation 4 = ab^0, which simplifies to a = 4.
Using the point (1,24), we plug in x=1, y=24, and a=4 to get the equation 24 = 4b^1, which simplifies to b = 6.
Therefore, the equation of the exponential function is y = 4(6)^x.

What are the steps to find (2+2i)(5+3i)?
Answer:
Step-by-step explanation:
(2+2i)(5+3i)
(2)5+(2)3i=10+6i
(2i)5+(2i)3i=10i+6i^2
10+6i+10i+6i^2
6i^2+6i+10i+10
6i^2+16i+10
To find the product of (2+2i)(5+3i), apply the distributive property to multiply each part. The result is 10 (real*real), 6i (real*imaginary), 10i (imaginary*real), and -6 (imaginary*imaginary, since i^2=-1), which are summed to give 4 + 16i.
Explanation:The product of two complex numbers, such as (2+2i)(5+3i), can be found by using the distributive property (also known as foil - first, outer, inner, laters). In this case:
First, multiply the real parts: 2*5 = 10. Second, multiply the outer parts: 2*3i = 6i. Then, multiply the inner parts: 2i*5 = 10i. Lastly, multiply the imaginary parts: 2i * 3i = 6i^2. But, since i^2 = -1, this becomes -6.
Sum these results together: 10 + 6i + 10i - 6. Thus, (2+2i)(5+3i)= 4 + 16i.

If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?
A) 3π cm
B) 6π cm
C)
9/4
π cm
D)
9/2
π cm
Answer: option B
Step-by-step explanation:
The circumference of a circle can be calculated with this formula:
[tex]C=2\pi r[/tex]
Where "C" is the circumference of the circle and "r" is the radius of the circle.
The area of a circle can be calculated with:
[tex]A=\pi r^2[/tex]
Where "r" is the radius.
Knowing the area, you can solve for the radius:
[tex]r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm[/tex]
Substituting into [tex]C=2\pi r[/tex], you get that the circumference of this circle is:
[tex]C=2\pi (3cm)=6\pi\ cm[/tex]
Answer:
B
Step-by-step explanation:
The area (A) of a circle = πr² ← r is the radius
here A = 9π, hence
πr² = 9π ( divide both sides by π )
r² = [tex]\frac{9\pi }{\pi }[/tex] = 9
r = [tex]\sqrt{9}[/tex] = 3
The circumference (C) of a circle is C = 2πr, hence
C = 2π × 3 = 6π → B

If m<1= 10x + 4 and m<2 =5x-4 find m<2
Answer:
m∠2 = 56°
Step-by-step explanation:
Given;
m∠1 = 10x + 4 and m∠2 = 5x - 4
Angles 1 and 2 are supplementary angles meaning that they add up to 180°
i.e,
(10x + 4) + (5x - 4) = 180°
10x + 5x + 4 - 4 = 180°
15x = 180°
x = 180/15 = 12
m∠2 = 5(12)° - 4° = 60° - 4° = 56°
