You measure 40 watermelons' weights, and find they have a mean weight of 67 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, what is the maximal margin of error associated with a 99% confidence interval for the true population mean watermelon weight.
Answer:
\(35.36,44.64\)
Step-by-step explanation:
Sample size \(n=40\)
Mean weight \(\=x =67\)
Standard deviation \(\sigma=11.4\)
Confidence Interval \(CI=0.99\)
\alpha==0.01
Therefore
\(Z_{\frac{\alpha}{2}}=Z_[0.005]\)
From table
\(Z_{\frac{\alpha}{2}}=2.576\)
Generally, the equation for Margin of error is mathematically given by
\(M.E=Z_{\frac{\alpha}{2}}*(\frac{\sigma}{sqrt{n}}\)
\(M.E=2.576*(\frac{11.4}{\sqrt{40}}\)

Suppose 100 children were killed by guns in 1950. If the original statement is true, about how many
children were killed by guns in 1995?
children
Using an exponential function, it is found that if the original statement is true, \(3.52 \times 10^{15}\) children were killed by guns in 1995.
Exponential function:An increasing exponential function is modeled by:
\(A(t) = A(0)(1 + r)^t\)
In which:
A(0) is the initial value. r is the increase rate, as a decimal.In this problem:
Researching on the internet, the original problem states that the number of children killed by guns has doubled each year since 1950, hence there is an increase of 100% every year, that is, \(r = 1\).100 children were killed by guns in 1950, hence \(A(0) = 100\).Then:
\(A(t) = A(0)(1 + r)^t\)
\(A(t) = 100(1 + 1)^t\)
\(A(t) = 100(2)^t\)
1995 is 45 years after 1950, hence:
\(A(45) = 100(2)^{45} = 3.52 \times 10^{15}\)
If the original statement is true, \(3.52 \times 10^{15}\) children were killed by guns in 1995.

Your best friend, who is on spring break in Europe, e-mailed you that the temperature in Paris today is . Use the formula F
, where F is degrees and C is degrees , to find the approximate Paris temperature in degrees .
Answer:
Assuming your friend said the temperature over there was 68 degrees Fahrenheit in degrees C it would be 20 °CStep-by-step explanation:
The question is not complete, as the information, your best friend in Europe about the temperature over there is missing, nevertheless, we can proceed with this problem by plugging in an assumed temperature.
The expression for conversion from degrees F to degrees C is given as
T(°C) = (T(°F) - 32) × 5/9
Now say temperature your friend e-mailed you is 68 degrees Fahrenheit (you can as well plug in your own value)
T(°C) = (68°F - 32) × 5/9
T(°C) = (36) × 5/9
T(°C) = 180/9 = 20 °C
T(°C) = 20 °C
What is the value of X when the richer scale rating is 3.1 round your answer to the nearest hundredth
3172.97 joules is the value of x when the Richter scale rating is 3.2
The equation that relates earthquake magnitude (M) and energy (E) is:
M = 2/3 × log(E) - 1.8
We have to find the value of X when the richer scale rating is 3.1
If an earthquake with a rating of 3.2 is not usually felt, then we can assume that x corresponds to the energy released by an earthquake that is just barely felt.
According to the United States Geological Survey, an earthquake with a magnitude of 2.5 corresponds to an energy release of about 1.3 × 10⁸ joules.
Using this as a reference point, we can set up the following equation:
3.2 = 2/3 × log(x) - 1.8
Solving for x, we get:
2.3 = 2/3 × log(x)
log(x) = 3.45
x = 3172.97
Therefore, the value of x when the Richter scale rating is 3.2 is approximately 3172.97 joules.

You decide to use the larger suitcase to transport rectangular prism watermelons back home. The watermelons are about 720 cubic inches. If one of the watermelons is about 10 inches long and 9 inches wide, about how tall would it be? (Hint: V=LxWxH, so plug in 720=10x9xH and solve for H).
If the watermelons are about 720 cubic inches, what is the MAXIMUM amount of watermelons you’ll be able to bring home in your larger suitcase, assuming all you have in the suitcase is the watermelons. (Hint: Divide the larger suitcase volume and the volume of the watermelon).
1. The volume of the black bag is 1728 cubic inches. 2. The volume of the blue bag is 2700 cubic inches. 3. The black bag will fit in the Check Box. 4. The bigger suitcase is 27 times larger than the smaller suitcase.
What is volume?Volume, which is commonly expressed in cubic units, is the amount of space occupied by a three-dimensional object. By multiplying an object's length, breadth, and height, as well as other formulas depending on the shape of the object, one can get the volume of the thing. Volume is a key concept in many practical applications, including calculating container capacity, constructing structures, and estimating the amount of material required for a construction project. Volume is utilised in many branches of mathematics, science, and engineering.
For the given dimensions of the bags we have:
1. The volume of the black bag is:
18 x 12 x 8 = 1728 cubic inches
2. The volume of the blue bag is:
18 x 15 x 10 = 2700 cubic inches
3. The black bag will definitely fit in the Check Box because its volume of 1728 cubic inches is less than the volume of the Check Box, which is 2772 cubic inches.
4. The ratio of bigger suitcase to smaller suitcase is:
75 x 20 x 18 = 27000 cubic inches
25 x 8 x 9 = 1800 cubic inches
27000 / 1800 = 27
The bigger suitcase is 27 times larger than the smaller suitcase.

Mushrooms have a yield factor of 90%. A 15 pound flat of mushrooms cost $29.85. What is the ap,cost per pound?
Answer: $2.21
Step-by-step explanation:
To calculate the cost per pound of mushrooms, we need to use the yield factor given in the question. The yield factor tells us the percentage of the total weight of the mushrooms that can be used for cooking or sale. Here, the yield factor is 90%, which means that 90% of the weight of the mushrooms can be used. Let's begin with the calculation:
First, we need to find out how much of the weight of the mushrooms is usable: 90% of 15 pounds = 0.9 x 15 = 13.5 pounds
Now, we can find out the cost per pound of the mushrooms:
Cost per pound = Total cost / Total usable weight
Total cost = $29.85
Total usable weight = 13.5 pounds
Therefore, the cost per pound of mushrooms = $29.85 / 13.5 pounds ≈ $2.21 per pound
Therefore, the cost per pound of mushrooms is $2.21 per pound.

Kimberly had 2 times as many marshmallows as Chris. After eating 15 each, Kimberly had 3 times as many marshmallows as Chris. Kimberly had 60 marshmallows at first.
What is Kimberly's marshmallows count?Generally, Let's call the number of marshmallows that Kimberly had at first X.
We know that Kimberly had 2 times as many marshmallows as Chris at first, so Chris had X/2 marshmallows.
After eating 15 each, Kimberly had X - 15 marshmallows, and Chris had X/2 - 15 marshmallows.
We also know that Kimberly had 3 times as many marshmallows as Chris after eating 15 each, so
(X - 15) = 3 * (X/2 - 15).
(X - 15) - 3 * (X/2 - 15) = 0
Then, we can simplify the left side of the equation:
X - 15 - 3 * X/2 + 45 = 0
Combining like terms, we get:
-3 * X/2 + X - 15 + 45 = 0
Simplifying further:
-X/2 =-30
X = 60

giải phương trình Bermolli : y' +\(\frac{y}{x}\) =x\(y^{2}\)
Answer:
y(x) = -1/(x^2 + c_1 x)
Step-by-step explanation:
Solve Bernoulli's equation ( dy(x))/( dx) + y(x)/x = x y(x)^2:
Divide both sides by -y(x)^2:
-(( dy(x))/( dx))/y(x)^2 - 1/(x y(x)) = -x
Let v(x) = 1/y(x), which gives ( dv(x))/( dx) = -(( dy(x))/( dx))/y(x)^2:
( dv(x))/( dx) - v(x)/x = -x
Let μ(x) = e^( integral-1/x dx) = 1/x.
Multiply both sides by μ(x):
(( dv(x))/( dx))/x - v(x)/x^2 = -1
Substitute -1/x^2 = d/( dx)(1/x):
(( dv(x))/( dx))/x + d/( dx)(1/x) v(x) = -1
Apply the reverse product rule f ( dg)/( dx) + g ( df)/( dx) = d/( dx)(f g) to the left-hand side:
d/( dx)(v(x)/x) = -1
Integrate both sides with respect to x:
integral d/( dx)(v(x)/x) dx = integral-1 dx
Evaluate the integrals:
v(x)/x = -x + c_1, where c_1 is an arbitrary constant.
Divide both sides by μ(x) = 1/x:
v(x) = x (-x + c_1)
Solve for y(x):
y(x) = 1/v(x) = -1/(x^2 - c_1 x)
Simplify the arbitrary constants:
Answer: y(x) = -1/(x^2 + c_1 x)

The coordinates of the vertices of DEF are D(2,3), E(4,0), and F(1,−2). The coordinates of the vertices of TVW are T(0,3), V(−2,0), and W(1,−2).
Answer:
To find the equation of the line containing the segment DE, we can use the coordinates of D and E to find the slope:
slope = (change in y) / (change in x) = (0 - 3) / (4 - 2) = -3/2
We can use the point-slope form of the equation of a line, using either D or E as the point:
y - 3 = (-3/2)(x - 2)
Simplifying this equation, we get:
y = (-3/2)x + 6
Similarly, to find the equation of the line containing the segment EF, we can find the slope using the coordinates of E and F:
slope = (change in y) / (change in x) = (-2 - 0) / (1 - 4) = 2/3
Using either E or F as the point, we can write the equation in point-slope form:
y - 0 = (2/3)(x - 4)
Simplifying, we get:
y = (2/3)x - (8/3)
To find the equation of the line containing the segment TV, we can find the slope using the coordinates of T and V:
slope = (change in y) / (change in x) = (0 - 3) / (-2 - 0) = 3/2
Using either T or V as the point, we can write the equation in point-slope form:
y - 3 = (3/2)(x - 0)
Simplifying, we get:
y = (3/2)x + 3
Finally, to find the equation of the line containing the segment VW, we can find the slope using the coordinates of V and W:
slope = (change in y) / (change in x) = (-2 - 0) / (1 - (-2)) = -2/3
Using either V or W as the point, we can write the equation in point-slope form:
y - 0 = (-2/3)(x - (-2))
Simplifying, we get:
y = (-2/3)x + (4/3)

Bola will be 8 years old.
Let Bola's age be x
Dada's age be y
Ayo's age be z
If the sum of ages of Bola, Dada, and Ayo is 32 years, then;
x + y + z = 32
If they share a sum of money in the ratio of their ages, then the ratio of their ages will be x: y: z
Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:
T = 400 + 400 + 800
T = N1600
Next is to get the age of Bola
\(\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share\)
Substitute the required variables and values into the formula;
