Answer:
0.188
Step-by-step explanation:
The computation is shown below;
First we have to determine the no of smokers
= Total no of persons - number of non-smokers
= 271 - 220
= 51
Now we have to estimate the proportion
So for this
= 51 ÷ 271
= 0.188192
= 0.188
Hence, the estimation is 0.188
The same is to be considered

Scientists are studying a bacteria sample. The
function f(x) = 245(1.12) gives the number of
bacteria in the sample at the end of x days.
Which statement is the best interpretation of one of
the values in this function?
The initial number of bacteria is 12.
The initial number of bacteria decreases at a rate of 88% each
day.
The number of bacteria increases at a rate of 12% each day.
The number of bacteria at the end of one day is 245.
The best interpretation of one of the values of the function is that the rate increases by 12% each day.
Step-by-step explanation:
Given:
F(x)=245(1.12)^x
To Find:
statement is the best interpretation of one of the values of the function
Solution:
Depending upon the values given the statement can be developed
As the function is itself the exponential growth structure ,
In this the statement ,Growth can be significantly depends on all factor
Such as time period initial value and rate.
But here the formula is simplified as ,
Here A= initial value r=rate and t =time period
Here A=245 and 1+r=1.12
i.e r=0.12 i.e 12%
Hence the rate give the best interpretation and more information about the function and scenario.

Answer:
[tex]\bold{y=3x-11}[/tex]
Step-by-step explanation:
Begin with the equation [tex]y=mx+b[/tex]. Let's first find [tex]m[/tex].
For each time [tex]x[/tex] increases by 2 (the rows skip by 2), [tex]y[/tex] increases by 6. Since the relationship is linear, if [tex]x[/tex] were to increase by just 1 (half of 2), [tex]y[/tex] would increase by 3 (since we halve each component). Therefore, [tex]m=3[/tex].
To find [tex]b[/tex] (the y-intercept), we plug in the first value of [tex]x[/tex] we are given and notice the result. In this case, [tex]4 *3=12[/tex]. However, the first value of [tex]y[/tex] is 1, so we must subtract 11 so that the first term is 1. Hence, [tex]y=3x+11[/tex].

If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
Answer:
The future value is $3793.776
Step-by-step explanation:
Given
[tex]PV = 2940[/tex] --- present value
[tex]r = 3.2\%[/tex] --- rate
[tex]t = 8[/tex] --- time
[tex]n = 4[/tex] --- quarterly
Required
Determine the future value
This is calculated using:
[tex]FV = PV(1 + \frac{r}{n})^{nt[/tex]
So, we have:
[tex]FV =2940 * (1 + \frac{3.2\%}{4})^{4*8[/tex]
[tex]FV =2940 * (1 + \frac{3.2}{400})^{32[/tex]
[tex]FV =2940 * (1 + 0.008)^{32[/tex]
[tex]FV =2940 * (1.008)^{32[/tex]
[tex]FV =2940 * 1.2904[/tex]
[tex]FV =3793.776[/tex]

Hello, I Am BrotherEye
Answer:
Median = 46.5
Minimum = 32
Maximum = 62
Lower quartile = 38
Upper quartile = 59
Step-by-step explanation:
Before we can proceed to solving any of these, it is best you arrange your data first from least to greatest
32 34 37 39 41 45 48 53 58 60 61 62
First we have the median. The Median is the middle value. In this case we an even number of data, which is 12 data points. The middle value of the data would be found in between the 6th and 7th data point:
45 and 48
To get the middle value, you need to solve for the value that is in the middle of 45 and 48 by getting the sum of both numbers and dividing it by two.
45 + 48 = 93
93 ÷ 2 = 46.5
The minimum and maximum value is merely the least and greatest number.
Here we have:
Minimum = 32
Maximum = 62
To get the lower and upper quartiles, just remember that quartiles divide the data into 4 equal parts. All you need to do is find the value that is in between each quarters of the data:
Q1 (Lower) Q2(Median) Q3(Upper)
32 34 37 | 39 41 45 | 48 53 58 | 60 61 62
Like the median, we will find the value that comes in between each quarter.
Q1
37 + 39 = 76
76 ÷ 2 = 38
Lower quartile = 38
Q3:
58 + 60 = 118
118 ÷ 2 = 59
Upper quartile = 59
Answer:
median - 46.5
Lower quartile - 38
Upper quartile - 59
Maximum - 62
Minimum - 32

Answer:
6 × 5
Step-by-step explanation:
If you want to reduce the fraction 12/30, you want to find the greatest common factor of 12 and 30. We can find that by looking at the prime factorization of each number.
12 = 2·2·3
30 = 2·3·5
The greatest common factor is 2·3 = 6. This means ...
[tex]\dfrac{12}{30}=\dfrac{12}{6\times5}[/tex]
The product of interest is 6 × 5.

Additional comment
Any of the factor pairs of 30 could be used. Only the one shown is useful for reducing the fraction to lowest terms.
30 = 1×30 = 2×15 = 3×10 = 5×6

This exposition impractically catches the pith of New York City much superior to anything I will ever have the capacity to. As a Californian, I view New York as I envision a New Yorker in the Nineteenth Century would view California. The contemplation is practically outlandish. California is the boundlessness edged pool of a landmass. Its wide open meanders perpetually, forever of the open doors which it holds until the land drops into nothingness and the Pacific devours it.
New York then again, shouldn't exist. Many think of it as the zenith of human accomplishment, a mixture of humankind existing together with an enthusiastic feeling of a club, all living under the standard held high that drains, "New York." It is where ten million drums play to their own beat, yet all ring to a similar congruity.
Didion's involvement in the city echoes these tones. The city is undoubtedly a spot where a half year can transform into eight years, and a night out can transform into a marriage. Didion expressed, "It was an unendingly sentimental idea, the puzzling nexus of all affection and cash and power, the sparkling and short-lived dream itself."
This exposition goes about as Didion's adoration letter to the city, one that isn't composed starting with one captivated sweetheart then onto the next, yet rather as Socrates would keep in touch with Zeus in an incredible miracle of his god-like power. Didion sees New York as legendary Fate, culling and cutting the strings of life which would decide her way of presence. Didion drives home the thought that New York is a thought. It represents something. New York is synonymous with America.
Opportunity. Renewed opportunities. Acts of futility. It is the New Mesopotamia, the support of life held in its bin by the two streams which give it its separated liveliness. American contemporary articles endeavor to restore the sentimental nature which used to drive American writers like Whitman and Thoreau to compose, and she completes a magnificent activity of that. My inquiry is how does Didion's association with the city influence her life?

Step-by-step explanation:
A. Directions: Find the surface of the following. Round your answer to nearest
hundredths. (Use n = 3.14) Write your answer in your notebook.
1) cone with radius of 15 cm and slant height of 12 cm
2) cone with radius of 8 cm and slant height of 11 cm
3) sphere with radius of 3.2 cm
4) sphere with diameter of 6 cm
Answer:
1. S.A of a cone = 565.56 cm².
2. S.A of a cone = 276.496 cm².
3. S.A of a sphere = 128.696 cm².
4. S.A of a sphere = 113.112 cm².
Step-by-step explanation:
Given the following data;
1. Radius, r = 15cm
Slant height, l = 12cm
Mathematically, the surface area of a cone is given by the formula;
Surface area of a cone = πrl
Substituting into the formula, we have;
S.A of a cone = 3.142 * 15 * 12
S.A of a cone = 3.142 * 180
S.A of a cone = 565.56 cm²
2. Radius, r = 8cm
Slant height, l = 11cm
Surface area of a cone = πrl
S.A of a cone = 3.142 * 8 * 11
S.A of a cone = 3.142 * 88
S.A of a cone = 276.496 cm²
3. Radius, r = 3.2 cm
Mathematically, the surface area of a sphere is given by the formula;
Surface area of a sphere = 4πr²
Substituting into the formula, we have;
S.A of a sphere = 4 * 3.142 * 3.2²
S.A of a sphere = 4 * 3.142 * 10.24
S.A of a sphere = 40.96 * 3.142
S.A of a sphere = 128.696 cm²
4. Diameter, d = 6cm
Radius, r = diameter/2 = 6/2 = 3 cm
Surface area of a sphere = 4πr²
S.A of a sphere = 4 * 3.142 * 3²
S.A of a sphere = 4 * 3.142 * 9
S.A of a sphere = 36 * 3.142
S.A of a sphere = 113.112 cm²

Can someone help me with this part A: Members of a high school sports team are selling two popular items for a fundraiser:
candy bars and bags of chips. They earn $0.75 for every candy bar they sell and $0.50 for every
Dag of chips. The members want to earn at least $100 from all sales. The members of the sport
team estimate that they won't be able to sell more than 200 units in total.
Part A: Select all the inequalities that model the constraints for this situation, where x
represent the number of candy bars sold and y represent the number of bags of chips.
A. x 20
B. y20

Answer:
All the inequalities that model the constraints for this situation:
(d) x + y < 200 ;
(e) 0.75 x + 0.50 y ≥ 100
Step-by-step explanation:
What is inequality ?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
As, x represent the number of candy bars sold & y represent the number of bags of chips sold.
It is given that,
price for one candy bar = $0.75
also, price for one dag of chips = $0.50
So, price for 'x' candy bar = $0.75x
also, price for 'y' of chips = $0.50 y
Is is mentioned in question, the sale of candy bar and bag of chips shoud be atleast $100.
the First ineqaulity be,
0.75 x + 0.50 y ≥100
(which should the sales of candy baar and dag of chips be equal to 100 dollar or greater than 100 dollar)
Now, the second situation
Again, it is mentioned in the question is number of units (candy bar and dag of chips) should be not more than 200 units.
the second inequality be,
x+ y < 200
(which shows that number of candy bar and dag of chips should be less than 200 units.)
All the inequalities that model the constraints for this situation
(d) x + y < 200
(e) 0.75 x + 0.50 y ≥100
