A class rolled number cubes. The results are shown in the table. What is the experimental probability of rolling the number five? Round your answer to the nearest tenth.
Answers
Answer:
17.5%
Step-by-step explanation:
First you have to find how many times the number cube was rolled. To do that you add up all of the occurrences and get 42+44+45+44+47+46=268.
After finding the total amount of times the cube was rolled, you must find how many times the outcome you are looking for occurred, which in this case is 47 as 5 was rolled 47 times.
Now all you have to do is divide 47/268 and that will get you your answer as probability is expressed as how many times a specific outcome is observed (rolling a 5) over how many times you roll the dice. At the end you can simply multiply by 100 to turn it from decimal form to percent form.

Answers
Answer:
QRST is a rectangle.
Step-by-step explanation:
To decide whether this is a rectangle or not, we have the following options to choose from:
Prove that:
2 pairs of sides are parallel and one angle is 90°
2 pairs of opposite sides are equal and one angle is 90°
1 pair of sides is parallel and equal and one angle is 90°
All four angles are 90°
The diagonals are equal and bisect each other. (same midpoint)
I will go with option 1, because this only requires finding the slope of each of the 4 lines.
Note that:
points Q and R have the same

Pamela is 8 years older than Jiri. The sum of their ages is 62. What is Jiri's age?
Answers
Answer:
Jiri's age = 27
Step-by-step explanation:
Let's use x for Jiri's age.
Jiri's age = x
And because Pamela is 8 years older:
Pamela's age = x + 8
Since their ages added up equal 62, the equation will be:
x + x + 8 = 62
2x + 8 = 62
2x + 8 - 8 = 62 - 8
2x = 54
2x/2 = 54/2
x = 27
And because Jiri's age is x, Jiri's age will therefore be 27.
Hope this helped!
Answer:
Jiri is 27 years old.
Step-by-step explanation:
Step 1: Declare variables
Let Jiri’s age be \(\displaystyle x\) years old.Since Pamela is 8 years older than Jiri. Then, Pamela’s age is \(\displaystyle{8+x}\) years old.
Step 2: Form an equation
The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of \(\displaystyle{x+8+x=62}\) (sum of Jiri’s age and Pamela’s).
Step 3: Solve for x-term - add like terms (x-term)
\(\displaystyle{2x+8=62}\)
Step 4: Subtract both sides by 8
\(\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}\)
Step 5: Divide both sides by 2
\(\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}\)
Since Jiri’s age is defined as \(x\) years old. Therefore, Jiri’s age is 27 years old.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?
Answers
Answer:
We can start by using the formula:
time = distance / speed
Let t be the time (in hours) for Tom and Katherine to meet.
Tom's distance = Tom's speed x time = 14t
Katherine's distance = Katherine's speed x time = 10t
Since they are riding towards each other, the total distance they cover is the sum of their distances:
Tom's distance + Katherine's distance = 42 miles
14t + 10t = 42
Simplifying:
24t = 42
t = 42 / 24
t = 1.75 hours
Therefore, Tom and Katherine will meet after 1.75 hours of riding.
Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?
Answers
Answer:
Step-by-step explanation:
You are finding out each time how much is the items Zachary bought.
Then inputting a equation
$1,600 - ??? = $1,370
To find the unknown number, you must subtract the 2 original numbers.
$1,600 - $1,370 = $230
Computer costs: $230 leaving Zachary with $1,370 left.
Next, it says he purchased another computer...
$1,370 - ??? = $1,140
Again, we subtract the 2 original numbers to find the unknown.
$1,370 - $1,140 = $230 leaving Zachary with $1,140 left.
Now we input this data into an equation...
y = -230x + 1600.

Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answers
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Third Day:
50 - .14(50)
.9(50) + 50 + .06(50) + 50 - .14(50)

141
Answer:
They made 45 dollars the first day, 53 dollars the second day, and 43 dollars the third day. In total the made 141 dollars.
Step-by-step explanation:
For the first day you multiply the goal amount by the decimal or fraction that represents the percentage to get your answer. So it would be:
50 x 0.90 = 43For the second day you do the same as above, but once you get the answer to that step, you add fifty to it. You can also do it all in one step. It would look like:
50 x 0.06 = 33 + 50 = 53OR
50 + (50 x 0.06) = 53For the third day you would do the same as you did for the first day, then you would take that answer and subtract it from fifty. You can do this all in one step too. It should look like this:
50 x 0.14 = 750 - 7 = 43OR
50 - (50 x 0.14) = 43Then to get your final answer, you would just add all of the days up like this:
45 + 53 + 43 = 141So your answer would be 141 dollars, or $141.00

Answer:
Y= mx + b
so Y = 1/3x + 2

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Step-by-step explanation:
Total birds= 500
No.of geese= 30*500/100

Let no.of ducks =x
no.of chickens= x+50
No. of ducks+ chickens= 500-150= 350
x+x+50=350
2x=300
x=150
Thus he has 150 ducks.
30% of 500 = 150
There are 150 geese.
chickens > ducks.
500 - 150 = 350
"..50 more chickens than ducks.."
350 - 50 = 300
300 ÷ 2 = 150
150 + 50 = 200
there are 200 chickens
There are 150 ducks
