Answer:
P = 12.50 + 1.25t
Step-by-step explanation:
To find an equation to represent the price of a pizza, we need to first figure out the original price of a pizze.
Since the price is 16.25 dollars, and there are 3 toppings, each of which cost 1.25, the original price would be:
16.25 - 3(1.25) = 12.50
Thus, we can represent the cost of a pizze with toppings as:
P = 12.50 + 1.25t, where P = Price and t = amount of toppings.
Hope this helps!
. A polling organization announces that the proportion of American voters who favor congressional term limits is 64%, with a 95% confidence margin of error of 3%. If the opinion poll had announced the margin of error for 80% confidence rather than 95% confidence, this margin of error would be (a) 3%, because the same sample is used. (b) less than 3%, because we require less confidence. (c) less than 3%, because the sample size is smaller. (d) greater than 3%, because we require less confidence. (e) greater than 3%, because the sample size is smaller.
When C.I. is given as 80% then the margin of error will be 1.9591% as calculated from the given data.
We are given that the first margin of error (MOE) is 3%.
Also, confidence interval
first C.I.=95%
second C.I.=80%
Therefore , MOE at 80% will be ,
The formula for proportion is given as (P),
P=x/n , here 64%.
The values are same or constant as in general, this means standard deviation is also constant
Now formula for MOE is given by
MOE = Z x ( SD ) / √n
where , Z is value for confidence interval
MOE ∞ Z-value
So we can say that ,
MOE = k x Z ( where k = proportionality constant).
So , for 95 % Z=1.96 and for 80% Z=1.28
MOE then calculated will be , 1.95% .

The number of visits Jaya can make to earn his first free movie ticket is 8
Total reward points received for signing up by Jaya = 85 rewards point
Total reward points received for each visit to the theatre by Jaya = 8.5 rewards point
Total reward points needed to Jaya for getting a free movie ticket = 153 rewards point
Let x represents the number of visits to the movie theatre
According to the question,
We can write it as:
85 + 8.5x ≥ 153 ------(i)
Now subtract 85 from both the side of equations,
We will get it as follows:

How do you calculate seed multiplication ratio?
The number of seeds produced from a single seed when it is sown and harvested is referred to as the seed multiplication ratio.
What is Seed?A seed is an undeveloped plant embryo and food reserve that is encased in a protective outer covering in botany. More broadly, "seed" refers to anything that can be sown, which could include seed and husk or tuber.
Seeds are the result of a ripened ovule being fertilised by sperm from pollen, resulting in a zygote. The embryo within a seed develops from the zygote, forming a seed coat around the ovule and growing to a certain size within the mother plant before growth stops.
The formation of the seed is a step in the reproduction process of seed plants (spermatophytes). Other plants, such as ferns, mosses, and liverworts, do not have seeds and must reproduce through water-based means.

How do you check if an inverse is a function?
If a value of y relates only to one value of x, then the function does have an inverse function.
Define the term function and its inverse?A relation between such a collection of inputs and outputs is known as a function.
A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is just the input.If and only if the outcome of reflecting a function's graph about the line y = x is the function's graph, then the function f does have an inverse (passing from the vertical line test).Thus, if a value of y relates only to one value of x, then the function does have an inverse function.

The population of Smallville in the year 1890 was 6250. Assume the population increased at a rate of 2.75% each year. a) Estimate the population in 1915 and 1940. b) Predict when the population reached 50,000
If the population grew 2.75% each year then each year the population was multiplied by 1+2.75%=1+0.0275=1.0275
What is the population of Smallville in 1890 was 6250?Population in the year 1890 = 6250. Population increased at the rate of 2.75% per year or increased by 11400 , which will become 411400 after the increaseif you were to do it a step at a time it would mean multiplying 6250 by 0.0275(2.75%), and adding the result to 6250, then repeating the operation with the new number for each year until you reached the amount of years required (25 and 50 years).Now an easier way to do that first step would be multiplying by 1.0275, which already takes care of adding the original number.

, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 6 years
The amount of money in the account after 6 years is $68,847.56
To solve this problem, you can use the formula for compound interest,
V = Pe^(rt)where V is the final value of the account, P is the initial principal, r is the annual interest rate (expressed as a decimal), and t is the number of years the money is invested.
The formula for compound interest, V = Pe^(rt) is used to calculate the future value of an investment. It takes into account the effect of compounding, which means that interest is earned not only on the initial investment but also on the accumulated interest over time.
Plugging in the given values, we have
V = 51200e^(0.0546) = 51200e^0.324. e^0.324 is approximately 1.38, so the final value of the account is 512001.38 = $68,847.56

The correct option is option (E) 15
To calculate the number of cookies they will need, they first determine the number of students who will be attending the meeting. Since attendance is down by 25%, the number of students attending is 108*(1-0.25) students.
=108 students * 0.75 = 81 students.
To figure out the number of cookies they will need, they multiply the number of students by the number of cookies per student, which is 81 students * 2 cookies= 162 cookies.
Since each recipe makes 15 cookies, they need to make 162 cookies / 15 cookies/recipe = 10.8 recipes.
Since they cannot make partial recipes, they round up and make 11 recipes of cookies for their smaller party.

I need help with this please
Answer in explanation:
*change the problem to [tex]\frac{5}{6}[/tex] x [tex]\frac{3}{1}[/tex]
(change 3 into a fraction by putting 1 in the place of a denominator)
next cross multiply
5 x /1
/2 1
3 can go into 6- 1 time
since anything multiplied by 1 is 1, the answer is [tex]\frac{5}{2}[/tex]
Hope this helps ya!
*(disclaimer lol: alternatively, you could cross multiply without changing 3 to a fraction and get the same answer-- however, I wanted to explain as clearly as possible, and figured it was less confusing this way!)
What is the value of 5 by 2?
The value of 5 divided by 2 is 2.5.
Therefore the answer is 2.5.
When dividing 5 by 2, we are trying to find out how many times 2 can fit into 5. The answer is 2 with a remainder of 1, this is why it can also be written as 2 and 1/2.
When dividing 5 by 2, we can also write the result as a fraction, in this case, it is 2 and 1/2 or 2.5 in decimal form. It is the exact same thing as 2.5, just represented in a different way.
It's important to note that, in general, dividing integers will give a decimal number. If you want the result to be a fraction, you will have to express it as such.
