You and two friends visit a pizza shop. There are 13 toppings. 8 toppings are meat and the rest are vegetable. each of you order a different topping (No Repeats) at random. what is the probability that your group orders only meat toppings

Answers

Answer 1

Answer: The probability of the first person ordering a meat topping would be 8/13 because 8 are meat out of the possible 13 toppings.
The probability of the second person ordering a different meat topping would be 7/12 because there are 7 other meat options out of now 12.
The probability of the third person ordering a different meat topping would be 6/11.
Multiply these fractions together. 8/13 x 7/12 x 6/11 = 28/143

A local discount store is famous for their motto, "Shop with us and you'll pay 20% less". Their claim is that every item in the store is already marked down 20% off of retail prices. In this Sunday's ad, they are advertising a scuba mask and snorkel set at their discount price of $28. Use a percent model to determine the original retail price of the scuba mask and snorkel set.

Answers

Answer:

Original retail price: $35

Step-by-step explanation:

20% off means that the discounted price is equivalent to 80% (100% - 20%) of the retail price.

Calling x the retail price of the scuba mask and snorkel set, then a discounted price of $28 means that this amount of money is 80% of x. Mathematically:

80*x/100 = $28

x = $28*100/80

x = $35

Use percentage multipliers:
$28/0.8 = $35
The original price of the set is $35.

A colony contains 1500 bacteria. The population increases at a rate of 115% each hour. If x represents the number of hours elapsed, which function represents the scenario?A f(x) = 1500(1.15)x

B f(x) = 1500(115)x

C f(x) = 1500(2.15)x

D f(x) = 1500(215)x

Answers

Answer:

Option (c) is correct.

$f(x)=1500(2.15)^x$ function representing the increase of bacteria every hour x,

Step-by-step explanation:

Given : A colony contains 1500 bacteria. The population increases at a rate of 115% each hour.

we have to find the function that represents the given scenario.

Let x represents the number of hours elapsed.

Given A colony contains 1500 bacteria

and number of bacteria is increasing at a rate of 115% each hour.

Using formula for Compound interest , we have,

$A=P(1+(r)/(100) )^t$

Where A is amount

T is time period

R is rate of interest

Here, P = 1500

T = x hours

R = 115%

Let f(x) be the function representing the increase of bacteria every hour.

Substitute, we have,

$f(x)=1500(1+(115)/(100) )^x$

Simplify, we get,

$f(x)=1500(1+1.15)^x$

$f(x)=1500(2.15)^x$

Thus, $f(x)=1500(2.15)^x$ function representing the increase of bacteria every hour x,

its f(x)=1500(2.15)x so c hope this helps

Determine the area of the regular hexagon

Answers

Answer:To determine the area of a regular hexagon, we need to use the formula:

Area = (3√3 * s^2) / 2

Where:

- s represents the length of one side of the hexagon.

In the given question, the side length of the regular hexagon is not provided. Therefore, we cannot calculate the exact area without that information.

However, if we assume the side length is 7.79 meters, we can substitute it into the formula to find the area:

Area = (3√3 * (7.79)^2) / 2

Area = (3√3 * 60.6641) / 2

Area ≈ 104.434 square meters (rounded to three decimal places).

Again, please note that this answer assumes the side length of the hexagon is 7.79 meters. If the actual side length is different, the area will also be different.
