Given:
The initial population = 750,000
23% of the population becomes a zombie everyday.
To find:
The function that represents p, the number of unaffected people after x days.
Solution:
The general exponential decay function is:
[tex]P=P_0(1-r)^x[/tex] ...(i)
Where, [tex]P_0[/tex] is the initial population, r is the rate of decay and x is the time period.
We know that,
The initial number of unaffected people = 750,000
The unaffected people decreasing by 23% . The decimal form of 23% is 0.23.
Putting [tex]P_0=750000, r=0.23[/tex] in (i), we get
[tex]P=750,000(1-0.23)^x[/tex]
[tex]P=750,000(0.77)^x[/tex]
Therefore, the required function is [tex]P=750,000(0.77)^x[/tex], where p is the number of unaffected people after x days.

Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items?
Answer:
Total amount pay by Ben = $82.27 (Approx.)
Step-by-step explanation:
Given:
2 Shirts = $16 each
3 pairs of socks = $2.50 each
1 pair of jeans = $37.75 each
Sales tax = 6.5%
Find:
Total amount pay by Ben
Computation:
Total amount for shirts = 2 x 16
Total amount for shirts = $32
Total amount for socks = 3 x 2.50
Total amount for shirts = $7.50
Total amount before tax = $32 + $7.50 + $37.75
Total amount before tax = $77.25
Total amount pay by Ben = Total amount before tax[1+tax]
Total amount pay by Ben = 77.25[1+6.5%]
Total amount pay by Ben = $82.27 (Approx.)

The area of Lebron's scale copy is 54 square inches.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
Here actual dimensions of the drawing are 12 feet by 18 feet.
Given that the scale is 1 inch = 2 feet.
This means 1 feet = 1/2 inch
So scale dimensions of the drawing :
12 × 1/2 inch and 18 × 1/2 inch
6 inches and 9 inches
Now, the area of Lebron's scale copy :
⇒ 6 inches × 9 inches
⇒ 54 square inches
Thus, the area of Lebron's scale copy is 54 square inches.

Step-by-step explanation:
Answer:
(3) (4x - 9)(4x + 9)
Step-by-step explanation:
4x times 4x will give you 16x^2, and 9 times 9 is 81, but you need to have one of the nines negative to give you the -81.
You needed the square root of 16 and the square root of x^2, then the square root of 81.

A game decreased in price by 1/4
After the reduction it was priced at £27.
What was the original price of the game
Answer:
£36.
Step-by-step explanation:
Because the game was reduced by 1/4
This means that:
£27 = 3/4.
To find 1/3, divide 27 by 3. this gives us 9. Now we know that the game was reduced by £9. To find the original price, instead of taking £9 away, we do the inverse and add the £9. This gives us £36.
You can even check your answer also, as 9 is 1/4 of 36, this proving that the price before the reductio was £36.

Alan rented a truck for one days.There base fee of $20.99,and there was an additional charge of 84 cents for each mile driven. Alan had to pay $267.11 when he returned the truck. How many miles did he drive the truck?
Answer: 293 miles
Step-by-step explanation:
First remove the fixed cost of the base fee so we can find out the amount spent on the miles driven:
= 267.11 - 20.99
= $246.12
Alan is charged 84 cents for each mile driven and the total came to $246.12.
84 cents in dollar notation = $0.84
The total miles driven is therefore:
= 246.12 / 0.84
= 293 miles

According to the Statistical Abstract of the United States, in 2000, 10.7% of Americans over 65 years of age use the Internet. A researcher believes the proportion of Americans over 65 using the Internet has changed since then. Determine the null and alternative hypotheses. Label which one is the claim. You must write the correct parameter, inequality/equality symbol and value to receive full credit.
Answer:
H0 : μ = 0.107
H1 : μ ≠ 0.107
Step-by-step explanation:
The claim is the alternative hypothesis. H1 ; which is a researcher's opinion that the proportion of Americans aged 65 and above using the internet as changed from the mean value of 10.7% (0.107). The direction of the change is not given, hence. We cannot use the greater or less Than sign as the direction of the change isn't specified by the researcher or data Given. Hence, the shift could be either to the right or left. Hence, the use of the equal to and not equal to sign.
The null will oppose the alternative hypothesis and take the stance that the proportion hasn't changed from the initial mean.
