The number of carbon atoms in a fossil is given by the function y= 5100(0.95)^x where x represents the number of years since being discovered what is the percent change each year? Explain your answer.
The function y = 5100(0.95)^x represents an exponential decay of the number of carbon atoms in a fossil, with a base of 0.95. Therefore, the percent change each year is -5%, reflecting a decrease, consistent with the decay of carbon-14.
Explanation:The function y = 5100(0.95)^x represents an exponential decay, with 0.95 being the base of the exponent. This base number, when subtracted from 1 and multiplied by 100, gives the percent change each year for the number of carbon atoms in the fossil.
Using this method, we find: (1-0.95)*100 = 5. So the percent change is -5% each year, with the negative sign indicating a decrease. This is consistent with the decay of carbon-14 (C-14) in fossils, a process used in carbon dating to estimate the age of the fossil.

8) An ultimate frisbee team has to order jerseys, shorts, and hats. They have a budget of $1350 to
spend on $50 jerseys, $20 shorts, and $15 hats. They want to buy 40 items in preparation for the
oncoming season and must order as many jerseys as shorts and hats combined. How many of
each item should they order? Write a system of equations to help you solve this problem.
Answer:
Step-by-step explanation:
By using j, s ,h to represent the number of jerseys,shorts and hats respectively.
System of Equations:
j + s + h = 40
j = s + h
50j + 20s + 15h = 1350
(s + h) + s + h = 40
2s + 2h = 40
s + h = 20
s = 20 – h
50[(20 – h) + h] + 20(20 – h) + 15h = 1350
50(20) + 400 – 20h + 15h = 1350
1400 – 5h = 1350
5h = 50h
h = 10
s = 20 – 10
s = 10
j = 10 + 10
j = 20
20 jerseys, 10 shorts, 10 hats
They order 20 jerseys, 10 shorts, 10 hats
What is system of equation?A system of equations, also known as a set of simultaneous or equation system, is a finite set of equations for which we sought the common solutions.
According to the question
By using j, s ,h to represent the number of jerseys ,shorts and hats respectively.
System of Equations:
j + s + h = 40. . . . . Equation (1)
j = s + h. . . . . . .Equation (2)
50j + 20s + 15h = 1350 . . . . . . Equation (3)

The 2003 Statistical Abstract of the United States reported the percentage of people 18 years of age and older who smoke. Suppose that a study designed to collect new data on smokers and non smokers uses a preliminary estimate of the proportion who smoke of .30.a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of.02? use 95% confidence.b. Assume that the study uses your sample size recommendation in part (a) and finds 520 smokers. What is the point estimate of the proportion of smokers in the population?c. What is the 95% confidence interval for the proportion of smokers in the population?
Answer:
Step-by-step explanation:
Confidence interval is written as
Sample proportion ± margin of error
Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
a) From the information given,
Margin of error = 0.02
p = 0.3
q = 1 - 0.3 = 0.7
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.5 = 0.05
α/2 = 0.05/2 = 0.025
This is the area in each tail. Since we want the area in the middle, it becomes
1 - 0.05 = 0.975
The z score corresponding to the area on the z table is 1.96. Thus, confidence level of 95% is 1.96
Therefore,
0.02 = 1.96 × √(0.3 × 0.7)/n
0.02/1.96 = √0.21/n
0.0102 = √0.21/n
Taking square of both sides, it becomes
0.00010404 = 0.21/n
n = 0.21/0.00010404
n = 2018
Sample size = 2018
b) if n = 2018
x = 520
Then
p = 520/2018 = 0.26
Point estimate of the proportion of smokers in the population is 0.26
c) q = 1 - 0.26 = 0.74
the 95% confidence interval for the proportion of smokers in the population is
0.26 ± 1.96 × √(0.26)(0.74)/2018
= 0.26 ± 0.019
Answer:
a) n = 2017
b) Point estimate is 0.2578
c) 95% Confidence Interval is Minimum = 0.2387, Maximum 0.2769
Step-by-step explanation:
Here we have
At 95%, we have
[tex]z_{\alpha /2}[/tex] = 1.96
To determine sample size, we have
[tex]n = \frac{(z_{\alpha /2})^2 \hat p \hat q}{E^2}[/tex]
Where:
[tex]\hat p[/tex] = 0.3
[tex]\hat q[/tex] = [tex]1-\hat p[/tex] = 0.7
E = 0.02
Therefore, n = 2016.84 ≈2017
b) The point estimate is given by
[tex]\hat p =\frac{x}{n} = \frac{520}{2017}[/tex] = 0.2578
c) The confidence interval is given by;
[tex]CI=\hat{p}\pm z\times \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]
Which gives
[tex]CI=0.2578\pm 1.96\times \sqrt{\frac{0.2578(1-0.2578)}{2017}}[/tex]
Hence CI = Min = 0.2387 to Max = 0.2769

\(4x\) divided by the GCF (4) is \(x\), and \(16\) divided by the GCF (4) is \(4\). Therefore, the expression \(4x + 16\) can be factored as \(4(x + 4)\) using the distributive property.
To summarize:
- GCF of 4 and 16 is 4.
- \(4x\) divided by the GCF (4) is \(x\).
- \(16\) divided by the GCF (4) is \(4\).

The equation of the line that passes through the point (6,-5)and has a slope of [tex]-\dfrac{3}{2}[/tex] is y+5 = -3/2(x+6).
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
WE need to find the equation of the line that passes through the point (6,-5)and has a slope of [tex]-\dfrac{3}{2}[/tex].
Given: m=-3/2 and x_1 = -6 and y_1 =-5
So the required equation of a line in a point-slope form;
y+5 = -3/2(x+6)

The equation of the line that passes through the point (6, -5) and has a slope of -3/2 is y = -3/2x + 4.
Explanation:To find the equation of the line, we can use the point-slope form of a linear equation, which is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. In this case, the point is (6, -5) and the slope is -3/2. Plugging these values into the equation, we get y - (-5) = -3/2(x - 6), which simplifies to y + 5 = -3/2(x - 6).
Expanding the equation further, we get y + 5 = -3/2x + 9. To isolate y, we can subtract 5 from both sides of the equation, resulting in y = -3/2x + 4. Therefore, the equation of the line that passes through the point (6, -5) and has a slope of -3/2 is y = -3/2x + 4.

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]

A shipping container in the shape of a rectangular solid must have a volume of 84 cubic meters. The client tells the manufacturer that, because of the contents, the length of the container must be one meter longer than the width, and the height must be one meter greater than twice the width. What should the dimensions of the container be?
Answer:
The Length , width and height of solid are 4 feet , 3 feet and 7 feet respectively.
Step-by-step explanation:
Let the width of rectangular solid be x
We are given that the length of the container must be one meter longer than the width
So, Length of solid = x+1
We are also given that height must be one meter greater than twice the width
So, Height of solid = 2x+1
So, Volume of solid = [tex]Length \times Width \times height[/tex]
Volume of solid = [tex](x+1) \times x \times (2x+1)[/tex]
Volume of solid =[tex](x^2+x)(2x+1)[/tex]
Volume of solid =[tex]2x^3+x^2+2x^2+x=2x^3+3x^2+x[/tex]
We are given that a rectangular solid must have a volume of 84 cubic meters
So, [tex]2x^3+3x^2+x=84\\2x^3+3x^2+x-84=0\\(x-3)(2x^2+9x-28)=0\\[/tex]
On equating
x-3=0
x=3
So, Length of solid = x+1=3+1 = 4 feet
Height of solid = 2x+1 =2(3)+1=7 feet
Width of solid = 3 feet
Hence The Length , width and height of solid are 4 feet , 3 feet and 7 feet respectively.
The volume of a rectangular solid shipping container = 84 cubic meters
The width of the container = 3m
The length of the container = (x + 1) = (3+1) = 4m
The height of the container = (2x + 1) = (2 x 3 + 1) = 7m
Given:
The volume of a rectangular solid shipping container = 84 cubic meters
Let: The width of the container be x
The length of the container must be one meter longer than the width.
So, The length of the container be (x + 1)
The height must be one meter greater than twice the width.
So, The height of the container be (2x + 1)
To find the dimensions of the container
The Volume of the container = Length x Width x Height
[tex]84=x(x+1)(2x+1)[/tex]
[tex]84=(x^{2} +x)(2x+1)[/tex]
[tex]84=2x^{3} +3x^{2} +x[/tex]
[tex]2x^{3} +3x^{2} +x-84=0\\(x-3)(2x^{2} +9x+28)=0\\x-3=0\\x=3[/tex]
So, The width of the container = 3m
The length of the container = (x + 1) = (3+1) = 4m
The height of the container = (2x + 1) = (2 x 3 + 1) = 7m

[tex]\frac{1}{2\frac{2}{7} } =\frac{1\frac{2}{5} }{x}[/tex] , where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
Answer:
3⅕ ft
Step-by-step explanation:
1 in --> 2 2/7 ft
2 2/7 = 16/7
1 2/5 in = 7/5 in
7/5 × 16/7 = 16/5 ft
3 1/5 ft
Find the Perimeter of the figure below, composed of a rectangle and two semicircles. Round to the nearest tenths place.
9514 1404 393
Answer:
43.1
Step-by-step explanation:
The perimeter is the sum of the lengths of the two straight edges, each of which is 9 units long, and the circumference of the full circle of diameter 8 units. The circumference is pi times the diameter.
P = 2(9) +8π = 18 +25.13
P ≈ 43.1 . . . units
The perimeter of the combination of a rectangle and two semicircles is found by adding the straight sides of the rectangle and the circumference of the resulting full circle formed by the semicircles. In this case, it's 43.1 units.
To find the perimeter of the combined shape consisting of a rectangle and two semicircles, we need to consider the lengths of the straight parts as well as the circumference of the circles. The perimeter is the sum of the lengths of the straight sides of the rectangle, each of which is 9 units long, and the circumference of the full circle with a diameter of 8 units.
Using the formula for the circumference of a circle (C = πd) where d is the diameter, the circumference of the full circle would be 8π. So, the total perimeter of the shape is:
P = 2*(9) + 8π
That gives us:
P = 18 + 25.13 approximately
So, P ≈ 43.1. . . units

Answer:
Step 2 is where this person went wrong
Step-by-step explanation:
Should be
11 + (9)(3)= x
11 + 27= x
x = 38
Answer:
Step 2 is where the error started. You can see the person did the order of operations wrong. The person was supposed to multiple (9)(3) first because of PEMDAS; (9)(3)=27 and then you add the 27 to 11 and get 38
