Create a Sample Space diagram and work out the probability - There is a 4 sided dice (numbers 1 to 4) and an 8 sided dice (numbers 1 to 8), the numbers on the 2 die are added together. What is the probability of scoring a number greater than 7? (write your answers in the form 1/2 with no spaces)
pls help quickly :)
Answer:
7 / 16
Step-by-step explanation:
Sample space is attached below :
Theoretical Probability of any event A
P(A) = (number of required outcome / Total number of possible outcomes)
Required outcome = sum greater than 7 = 14
Total number of possible outcomes = 32
P(sum greater than 7) = 14 / 32
P(sum greater than 7) = 7 / 16

A yard is equal in length to 3 feet the function takes a measurement in yards and returns a measurement and see what number will be the function return if the input is 10.5
Answer:
It will return 31.5 ft
Step-by-step explanation:
Here, the function is as follows;
let the yard be represented as y and the f be the feet
It takes in yards and return feet
Mathematically, using the relation between the two;
So for every yards it takes in, it returns 3 times the value in feet
Thus, for 10.5 yards, what it will return will be;
10.5 * 3 = 31.5 ft
James buys a shirt and a pair of socks on sale for 25% off.
If the price of the shirt before the sale was $24 and he spent a total of $24, what was the original price of the socks?
Enter your answer in the box.
I love these questions!
Anyway, let's figure out the original price, discount in percent, and new price. 25% is the discount in percent, the original price is unknown, and the new price is $24. Here is the equation.
O - Original price
d% - discount in percent
N - New price
O x (1 - d%) = N
O x (1 - 25%) = $24
O x (1 - 0.25) = $24
O x 0.75 = $24
0.75 0.75
O = $32
$32 - $24 = $8
Therefore, the original price of the socks is $8.
Answer:The Price of socks is
=$8
Explanation:Given -
Discount 25%
Price of shirt before discount =$24
Amount spent on both shirt and socks after applying discount
=$24
Assume the price of socks =$x
Then Shirt + Socks before discount =$(24+x)
After discount one has to pay 75% of the article.
Then = 75/100(24+x)=24
0.75(24+x)=24
18+0.75x=24
0.75x=24−18=6
x=6/0.75=8
The Price of socks is =$8
How to verify your answer -
One way
Price of shirt =$24
Price of socks =$8
Total =$32
Discount =25%
Discount for $32 is 32×25/100=$8
Amount one has to pay after discount =32−8=$24
Another way is -
Discount 25%
It means after discount it is enough if he pays 75% of the price.
In our case - Actual price is =$32
75% of $32 is =32×75/100=24

solve the following inequality for h. h-8> 4h+5
Answer:
h < -13/3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Inequality
h - 8 > 4h + 5
Step 2: Solve for h
Subtract h on both sides: -8 > 3h + 5Subtract 5 on both sides: -13 > 3hDivide 3 on both sides: -13/3 > hRewrite: h < -13/3Here we see that any value h smaller than -13/3 would work as a solution to the equation.

3e <= 6
e <= 2 (divide 3 on both sides)
The e-values that satisfy the inequality are:
e = 1 and e = 2.
Answer:
Solutions: e = 1 and e = 2
Step-by-step explanation:
3(1) ≤ 6
3 ≤ 6
3 is less than 6, so this works.
3(2) ≤ 6
6 ≤ 6
6 is equal to 6, so this works.
3(3) ≤ 6
9 ≤ 6
9 is not less than or equal to 6, so this does not work.

In 1995, the population of a town was 33,500. It is decreasing at a rate of 2.5% per decade.
a. Identify whether the function is a growth or decay function.
b. Write the function, f(n), that expresses the population of the town after (n) decades.
c. What is the population in the year 2025 to the nearest hundred?
Answer:
a. The function is a decay function
b. The function is f(n) = 33500 [tex](0.975)^{n}[/tex]
c. The population in the year 2025 is 31,800 to the nearest hundred
Step-by-step explanation:
The form exponential growth function is y = a [tex](1+r)^{x}[/tex] , where
a is the initial valuer is the rate of increase in decimalThe form exponential decay function is y = a [tex](1-r)^{x}[/tex] , where
a is the initial valuer is the rate of decrease in decimal∵ In 1995, the population of a town was 33,500
∴ a = 33,500
∵ It is decreasing at a rate of 2.5% per decade
→ The decrease means, it is a decay function, then use the 2nd form above
∴ f(n) = a [tex](1-r)^{n}[/tex] , where f(n) is the population in n decades
∴ It is a decay function
a. The function is a decay function
∵ The rate is 2.5% per decade ⇒ 2.5% each 10 years
∴ r = 2.5%
→ Divide it by 100 to change it to decimal
∵ 2.5% = 2.5 ÷ 100 = 0.025
∴ r = 0.025
→ Substitute the values of a and r in the f(n)
∴ f(n) = 33500 [tex](1-0.025)^{n}[/tex]
∴ f(n) = 33500 [tex](0.975)^{n}[/tex]
b. The function is f(n) = 33500 [tex](0.975)^{n}[/tex]
∵ We need to find the population in 2025
→ Find how many decades from 1995 to 2025
∵ There are 20 years from 1995 to 2025
∵ 1 decade = 10 years
∵ n is the number of decads
∴ n = 2 ⇒ (20/10 = 2)
→ Substitute n in the function by 2
∵ f(2) = 33500 [tex](0.975)^{2}[/tex]
∴ f(2) = 31845.9375
→ Round it to the nearest hundred
∴ f(2) = 31800
c. The population in the year 2025 is 31,800 to the nearest hundred
