18) 1, because [tex]2^{4}/{2^{4} =1[/tex]. Therefore [tex]2^{4}/{2^{4} = 2^{4-4}=2^{0}=1[/tex]
Step-by-step explanation:
12) Exponent Zero rule. Anything raise to 0 power equals 1.
13) Exponent Negative rule: [tex]b^{-n} =\frac{1}{b^n}[/tex]
14) Exponent Quotient rule: [tex](a^n/a^m)=a^{n-m}[/tex]
In this case, [tex](3^3/3^5)=3^{3-5}=3^{-2}=1/3^2=1/9[/tex]
15) Exponent Product rule: [tex](a^n*a^m)=a^{n+m}[/tex]
In this case, [tex](5^8*5^{-8})=5^{8-8}=5^0=1[/tex]
16) Same rule as #15, [tex](7^2*7^{-2})=7^{2-2}=7^0=1[/tex]
17)We can work backwards here, we know [tex]2^{2} = 4[/tex] and [tex]3^{1} =3[/tex], so we need [tex]2^2/3^1=4/3[/tex].
To achieve this, use Exponent Quotient rule, what x-4=1? x=5.
Similar base: [tex](3^5/3^4)=3^{5-4}=3^{1}=1/3[/tex]. Put [tex]2^{2}[/tex] back for [tex]\frac{4}{3}[/tex]
18) 1*1*1*1=1. Anything raise to 0 power equals 1 (Exponent Zero rule). To prove this, any number(except 0) divided by itself equals 1.
Ex: 1/1=1, 4/4=1, [tex]2^4/2^4=1[/tex].
We can prove this with the Exponent Quotient rule. [tex]1=\frac{3}{3} =\frac{3^1}{3^1}=3^{1-1}=3^0=1[/tex]. No matter how I write it, it's equal to 1.
The one exception is [tex]0^{0}[/tex], which is undefined, since dividing by zero is illegal.
Hope this helps. ;)

Answer: The train travels 50 miles per hour
Step-by-step explanation:
You already figured out the slope! The explanation is that the train travels 50 miles each hour.
The Slope Intercept form of the equation would be y=50x
If you substitute x with any number you can solve to see how much hours the train traveled.
So the train travels 50 miles per hour!

Tyrese wants to buy 15 packs of baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchased. Sales tax is 7%. Tyrese gives the cashier $100 to pay for his baseball cards.
How much change will he receive in return?
Answers
Answer:
$39.81
Step-by-step explanation:
$5.00 per pack
15 packs
25% discount for 10 or more packs
7% sales tax
paid $100
change?
A 25% discount means that you pay 75% of the price.
75% = 0.75
A 7% sales tax means that you pay 107% of the price.
107% = 1.07
15 × $5 × 0.75 × 1.07 = $60.19
$100 - 60.19 = $39.81
Answer: $39.81

whats the formula for simple interest?....HELP
Answers
The formula for calculating simple interest is:
Simple Interest = (Principal x Rate x Time) / 100
Where:
Principal = the initial amount of money (the "principal sum")
Rate = the interest rate (expressed as a decimal or percentage)
Time = the length of time the interest is applied (usually in years)
It's important to note that simple interest is a method where the interest is calculated only on the original principal sum, not on any accumulated interest.
The simple interest formula is
i = P*r*t
where,
i = interestP = deposit or starting amount or loan valuer = annual interest rate in decimal formt = number of years--------------------
An example:
You borrow $500 at a simple interest rate of 2% over 3 years
P = 500r = 0.02t = 3Use those values to compute the following:
i = P*r*t
i = 500*0.02*3
i = 30
The amount of interest only is $30; meaning the total amount to pay back is $500 + $30 = $530

-What is the y-intercept of the line of best fit?
-What is the slope of the line of best fit for this scatter plot?
-What is the equation of the line of best fit?
Answers
Answer:
y-intercept : 8
slope: -1/2
equation: [tex]y = -\dfrac{1}{2}x + 8[/tex]
Step-by-step explanation:
The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)
Slope of the line can be found by the formula (y2-y1) / (x2-x1) where 9x1, y1) and (x2, y2) are two points on the line
Let's take the points (0, 8) and (10, 3) the two extreme points on the line
Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2
Equation of a line in slope intercept form is
y = mx + c
where m is the slope
b is the y intercept
The equation of the line is therefore
[tex]y = -\dfrac{1}{2}x + 8[/tex]
Answer:
Y-intercept = 8
Slope = -1/2t
Equation = y =-1/2x+8
Step-by-step explanation:
When x = 0, y = y-intercept.
Therefore, the y-intercept is 8.
We can find the slope using the formula y2-y1 / x2-x1 = m.
Let's use the points (0,8) and (4,6)
6-8 / 4-0 = m;
m = - 1/2.
Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:
y = -1/2x+8.

What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that a gamer drew one card and recorded its value.
They continued this for a total of 100 draws.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
The total number of cards drawn is 4+7+5+6+7+6+8+10+7+10+8+12+10 = 90.
The number of cards drawn that are either a J, Q, or K is 10+8+12 = 30.
Therefore, the experimental probability of drawing a J, Q, or K is:
30/90 = 1/3
Hence, the experimental probability that the card selected was a J, Q, or K is 1/3.

Answers
Answer:
a=-2
b=3
Step-by-step explanation:
Solve the system of equations.
2a -5b = -19
3a + 5b = 9
Add the two equations together.
2a -5b = -19
3a + 5b = 9
------------------------
5a = -10
Divide by 5
5a/5 = -10/5
a = -2
Now we can find b
2a-5b = -19
2(-2) -5b = -19
-4 -5b = -19
Add 4 to each side
-5b = -15
Divide by -5
b = 3
a=-2
b=3
Given
2a-5b= -19 (equation1)
3a+5b = 9 (equation2)
now add both equation 1 and equation 2
2a-5b=-19
3a+5b= 9
------------------
5a = -10 (as +5b and -5b get canceled)
5a = -10
a = -2
(substitute in equation 2 or in equation 1)
3(-2)+ 5b= 9
-6 +5b =9
5b = 9+6
5b = 15
b= 3
therefore
a= -2
b= 3
verification:
2(-2)-5(3) = -19
-19 = -19
hence verified.

You roll 2 dice. How likely is it that you roll a 2 and a 5?
Impossible
Unlikely
Equally Likely
Likely
Certain
Answers
Answer:
It is likely that you roll a 2 and a 5. There are 36 possible combinations when rolling two dice, and one of those combinations is a 2 and a 5. Therefore, the probability of rolling a 2 and a 5 is 1 in 36, which is considered likely.
Explanation: If you have two dice and roll each one once, both dice has 1 in a 6 chance of rolling a 2 and a 5. One dice has to roll a 2 and the other dice has to roll a 5. The odds of them rolling a 2 and a 5 are highly unlikely, but not impossible.
