Answer:
A = 63.59
C = 28.26
Step-by-step explanation:
r = 4.5
Area of a circle:
A = πr²
A = 3.14(4.5²)
A = 3.14(20.25)
A = 63.59
Circumference:
C = 2πr
C = 2(3.14)(4.5)
C = 28.26
The school is hosting a game night. you are in charge of buying prizes for giveaways. movie tickets cost 8.50 and restaurant gift cards cost 15 you need at least 12 prizes but must spend less thatn 150
With the given budget, you can buy 12 movie tickets and 3 restaurant gift cards.
As the person in charge of buying prizes for the game night, your goal is to purchase at least 12 prizes while spending less than $150.
Movie tickets cost $8.50 each, and restaurant gift cards cost $15 each.
To determine how many of each prize you can buy, let's start by considering the cost of movie tickets.
If you buy 12 movie tickets at $8.50 each, the total cost would be 12 * $8.50 = $102.
Next, let's see how many restaurant gift cards you can buy.
Subtracting the cost of the movie tickets from the total budget of $150 gives us $150 - $102 = $48 remaining.
Since each gift card costs $15, you can buy $48 / $15 = 3 gift cards.
Now, let's summarize what you can buy with the given budget.
You can purchase 12 movie tickets at a cost of $102 and 3 restaurant gift cards at a cost of $45.
In total, this would be $102 + $45 = $147.
To double-check, we can verify that the total cost of the prizes is less than $150, which it is.
So, with the given budget, you can buy 12 movie tickets and 3 restaurant gift cards.

Is the decibel level of a siren discrete or continuous? O A. The random variable is discrete. B. The random variable is continuous.
The correct answer is option A: The random variable is discrete. A decibel is a unit of measure used to quantify the loudness or intensity of sound.
From 0 dB (the quietest level of sound) to 140 dB (the loudest level of sound), it is measured on a logarithmic scale (the highest level of sound).
The decibel level of a siren is normally between 110 and 120 dB, which is regarded to be within or close to the threshold of human hearing.
The decibel level of a siren is measured on a logarithmic scale, making it a discrete variable. This indicates that it is measured in whole numbers rather than fractions of a decibel.
For instance, a siren's decibel level can be 110 dB, 111 dB, 112 dB, etc., but it cannot be 110.5 dB or 111.5 dB. Therefore, the decibel level of a siren is a discrete variable.

Simplify the following expression: F = AB’C + AC’D + AC’D’ + AB May have to try using any or all of the three simplification theorems.
The simplified expression of the given expression F = AB’C + AC’D + AC’D’ + AB is F = AB’C + AC’D + AB’CD + AB’C’D + AB’C’D’.
To simplify the given expression F = AB’C + AC’D + AC’D’ + AB, we can apply Boolean algebra simplification theorems.
1.
Distributive Law (A(B + C) = AB + AC):
Apply the distributive law to the first term:
F = AB’C + AC’D + AC’D’ + AB
= AB’C + AB + AC’D + AC’D’
2.
Complement Law (A + A’ = 1):
Identify terms where a variable and its complement appear:
F = AB’C + AB + AC’D + AC’D’
= AB’C + AB + AC’D + AC’D’ + AB’CD + AB’C’D + AB’C’D’
(Added extra terms by multiplying by 1)
3.
Absorption Law (A + AB = A):
Combine terms where one term is a subset of another term:
F = AB’C + AB + AC’D + AC’D’ + AB’CD + AB’C’D + AB’C’D’
= AB’C + AC’D + AB’CD + AB’C’D + AB’C’D’

What is the median of this data set? 15, 14, 6, 10, 7, 15, 7, 8
The median of this set is:
9
A median is:In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result.

Identify all of the root(s) of g(x) = (x2 3x - 4)(x2 - 4x 29). -1 1 -4 4 2 5i 2 - 5i -2 10i -2 - 10i
The roots are (x + 1), (x - 4), (2 + 5i), and (2 - 5i).
g(x) = (x2 - 3x - 4)(x2 - 4x + 29)
Let us first consider x^2 - 3x - 4
By splitting the middle term
= x^2 + 1x - 4x - 4
= x(x + 1) - 4(x + 1)
= (x + 1)(x - 4)
Now let us consider x^2 - 4x + 29
First group the terms with variable on LHS and move the constant on the other side
x^2 - 4x = -29
Add 4 on both sides
x^2 - 4x + 4 = -29 + 4
x^2 - 4x + 4 = -25
It can be written as perfect squares
(x - 2)^2 = -25
We know that
i =√1
Take square root on both sides
x - 2 = ± 5i
x = 2 ± 5i
So we get,
x = 2 + 5i and x = 2 - 5i
g(x) = (x + 1)(x - 4)(2 + 5i)(2 - 5i)

StartFraction 34 Over 149 EndFraction StartFraction 15 Over 49 EndFraction StartFraction 18 Over 52 EndFraction StartFraction 37 Over 149 EndFraction
The proportion of those surveyed who chose basketball as their favorite sport is 34.149 (option a)
Let's denote the proportion of adults who chose basketball as their favorite sport as P(Basketball). To calculate P(Basketball), we need to divide the total number of adults who chose basketball by the total number of surveyed adults. Mathematically, it can be represented as:
P(Basketball) = (Number of adults who chose basketball) / (Total number of surveyed adults)
To calculate the number of adults who chose basketball, we sum up the values from the age range categories:
Number of adults who chose basketball = Number of adults (18-30) who chose basketball + Number of adults (31-50) who chose basketball + Number of adults (51 and above) who chose basketball
Looking at the table, we find that the number of adults (18-30) who chose basketball is 15, the number of adults (31-50) who chose basketball is 8, and the number of adults (51 and above) who chose basketball is 11. Adding these values together, we get:
Number of adults who chose basketball = 15 + 8 + 11 = 34
Now, let's calculate the total number of surveyed adults. We can sum up the values from the age range categories:
Total number of surveyed adults = Total number of adults (18-30) + Total number of adults (31-50) + Total number of adults (51 and above)
From the table, we find that the total number of adults (18-30) is 49, the total number of adults (31-50) is 48, and the total number of adults (51 and above) is 52. Adding these values together, we get:
Total number of surveyed adults = 49 + 48 + 52 = 149
Now, we have the values we need to calculate the proportion:
P(Basketball) = (Number of adults who chose basketball) / (Total number of surveyed adults)
= 34 / 149
Hence the correct option is (a).

when an object 1.00 cm tall is placed 12 cm from a lens, the lens produces an upright image of the object that is 5.00 cm tall. what is the focal length of the lens?
The focal length of the lens is -15 cm. The negative sign indicates that the lens is a diverging lens.
To find the focal length of the lens, we can use the lens formula:
1/f = 1/v - 1/u
where f is the focal length of the lens, v is the image distance, and u is the object distance.
Given:
Object height (h_o) = 1.00 cm
Object distance (u) = 12 cm
Image height (h_i) = 5.00 cm
We can use the magnification formula to relate the object and image heights:
Magnification (m) = h_i / h_o
Given:
m = h_i / h_o = 5.00 cm / 1.00 cm = 5.00
Now, let's substitute the values into the lens formula:
1/f = 1/v - 1/u
Since the image is upright, the image distance (v) will be positive.
1/f = 1/v - 1/u
1/f = 1/v - 1/12
To find the value of v, we can use the magnification formula:
m = v / u
5.00 = v / 12
v = 5.00 * 12
v = 60 cm
Now, substitute the values of v and u into the lens formula:
1/f = 1/60 - 1/12
Simplifying:
1/f = (1 - 5) / 60
1/f = -4/60
1/f = -1/15
Taking the reciprocal of both sides:
f = -15 cm
