so, total number of chocolates = 18×8 = 144 chocolate s
Explanation: To find out the original amount of chocolates she originally started with all you will have to do is multiply the amount of children their are and the amount they each got ( 18 x 8 ) and that will get you your answer (144)
Harpreet took out a payday loan of $500.00. He had to repay $540.00 within 7 days.
A) What was the daily interest on the loan
B) What was the annual interest?
Answers
Answer:
a) 1,14%
b) 317%
Step-by-step explanation
J = C . i . t
540 - 500 = 500 . i . 7
40 = 500 . 7 . i
i = 0,0114 = 1,14% within day
-------------------------------------------
J = 500 . 0,0114 . 365 = 2085,71
2085,71 - 500 = 500 . i . 1
1585,71 = 500 . i
i = 3,17 = 317% annual
Option a to buy a house has a monthly cost of 618 dollars, up-front cost of 24,000 dollars, and advantages of a home equity and a yard for a pet. option b to rent close to work has a monthly cost of 950 dollars, up-front cost of 1,900, and advantages of convenient location, garage, and pool. option c to rent further out has a monthly cost of 600 dollars, up-front cost of 1,200, and advantages of 2 bedrooms, light-rail, and pool. which housing choice fits within your recommended monthly budget of $650-780? which option requires you to have at least $24,000 saved?
Answers
Option c is the best option that can be recommended since it has the least total cost for a year.
What is the up-front cost?An upfront cost is an initial sum of money owed in a purchase or business venture.
Option a:
Monthly cost = $618
Up-front cost = $24000
Total cost for a year= 618*12+24000 = $31416
Option b:
Monthly cost = $950
Up-front cost = $1900
Total cost for a year= 950*12+1900= $13300
Option c:
Monthly cost = $600
Up-front cost = $1200
Total cost for a year= 600*12+1200= $8400
Therefore, option c is the best option that can be recommended since it has the least total cost for a year.

A medical researcher says that less than 25% of US adults are smokers. In a random sample of 200 US adults, 18.5% say that they are smokers. At α=0.05, is there enough evidence to reject the researchers claim?
Step 1: Identify the specific claim to be tested, and put it in symbolic form：
Step 2: Give the symbolic form that must be true when the original claim is false (the opposite)：
Step 3: Show the null and alternative hypotheses：
Step 4: Select the significance level α：
Step 5: Find the test statistic and critical value. Draw a graph and show the test statistic and critical value：
Step 6: Make a decision with regard to the null hypothesis (i.e. reject or fail to reject):
Step 7: Restate the decision in step 7 in simple nontechnical terms, and address the original claim:
Answers
The specific claim to be tested is that less than 25% of US adults are smokers. Let's represent this claim symbolically as H₀: p ≥ 0.25, where p represents the proportion of US adults who are smokers. The symbolic form that must be true when the original claim is false (the opposite) is H₁: p < 0.25.
The null hypothesis (H₀) is that the proportion of US adults who are smokers is greater than or equal to 25% (p ≥ 0.25). The alternative hypothesis (H₁) is that the proportion is less than 25% (p < 0.25).
We select the significance level α = 0.05, which represents the probability of rejecting the null hypothesis when it is true.
To test the hypotheses, we calculate the test statistic and critical value. The test statistic is the z-score, which can be computed using the sample proportion, the population proportion, and the sample size. The critical value corresponds to the z-score that corresponds to the chosen significance level.
After calculating the test statistic and comparing it with the critical value, we find that the test statistic falls within the critical region. Thus, we have enough evidence to reject the null hypothesis. In simple terms, the data suggests that the proportion of US adults who are smokers is less than 25%.
Therefore, based on the results of the hypothesis test, we can conclude that there is enough evidence to reject the claim made by the medical researcher and support the alternative hypothesis that less than 25% of US adults are smokers.

Integrate the ODE
dy/dx = x² √y, 0 < x < 2, y(0) = 1
using Euler's method (Δx = 0, 2) to compute y(2). Obtain analytical solution to the ODE and compare y(2) obtained using Euler's method with that obtained analytically.
Answers
we find that the numerical approximation using Euler's method gives y(2) ≈ 1.865, while the analytical solution gives y(2) = 2.5.
Using the formula y(n+1) = y(n) + Δx * f(x(n), y(n)), where f(x, y) = x² √y, we can calculate the values of y at each step. Here's the step-by-step calculation:
Step 1: For x = 0, y = 1 (initial condition).
Step 2: For x = 0.2, y = 1 + 0.2 * (0.2)² * √1 = 1.008.
Step 3: For x = 0.4, y = 1.008 + 0.2 * (0.4)² * √1.008 = 1.024.
Step 4: For x = 0.6, y = 1.024 + 0.2 * (0.6)² * √1.024 = 1.052.
Step 5: For x = 0.8, y = 1.052 + 0.2 * (0.8)² * √1.052 = 1.094.
Step 6: For x = 1.0, y = 1.094 + 0.2 * (1.0)² * √1.094 = 1.155.
Step 7: For x = 1.2, y = 1.155 + 0.2 * (1.2)² * √1.155 = 1.238.
Step 8: For x = 1.4, y = 1.238 + 0.2 * (1.4)² * √1.238 = 1.346.
Step 9: For x = 1.6, y = 1.346 + 0.2 * (1.6)² * √1.346 = 1.483.
Step 10: For x = 1.8, y = 1.483 + 0.2 * (1.8)² * √1.483 = 1.654.
Step 11: For x = 2.0, y = 1.654 + 0.2 * (2.0)² * √1.654 = 1.865.
Therefore, using Euler's method with a step size of Δx = 0.2, we approximate y(2) to be 1.865.
To obtain the analytical solution to the ODE, we can separate variables and integrate both sides:
∫(1/√y) dy = ∫x² dx
Integrating both sides gives:
2√y = (1/3)x³ + C
Solving for y:
y = (1/4)(x³ + C)²
Using the initial condition y(0) = 1, we can substitute x = 0 and y = 1 to find the value of C:
1 = (1/4)(0³ + C)²
1 = (1/4)C²
4 = C²
C = ±2
Since C can be either 2 or -2, the general solution to the ODE is:
y = (1/4)(x³ + 2)² or y = (1/4)(x³ - 2)²
Now, let's evaluate y(2) using the analytical solution:
y(2) = (1/4)(2³ + 2)² = (1/4)(8 + 2)² = (1/4)(10)² = 2.5

Step one: Decide if the two terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the two terms only have a 1 in common which is of no help.
Step 2: Rewrite the original problem as a difference of two perfect cubes.
Step 3a: “Write What You See” If you disregard the parenthesis and the cubes in step 2, you should see:
Step 3b: “Square-Multiply-Square” If you square the first term, x, you get x2. If you multiply the two terms, x and 4, you get 4x. Finally, if you square the second term, 4, you get 16.
Step 3c: “Same, Different. End on a Positive” This will determine the signs of the problem. The first sign should be the same as the original question, the next sign should be different then the first, and the last sign should always be positive.

Answers
Answer:
x and y can be any two numbers greater than zero such that y is also greater than x
D.no more than 45
C.50 miles per hour
Step-by-step explanation:
Let the two numbers be such that x< y because we have been given y/x>1 and x/y< 1 .
Suppose we take y= 9 and x= 3 then
9/3 > 1
3>1
Also
3/9 < 1
1/3 < 1
x and y can be any two numbers greater than zero such that y is also greater than x
2. Total weight that can be carried is 3000 pounds.
The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.
The smaller machines weigh 60 pounds
The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.
3. Total distance = Speed * time
= 48 * (40/60) = 32 miles
New distance = 32+ 8= 40 miles
New time = 48 minutes
Speed = distance / time = 40/ 48/60= 50 miles per hour

Answers
Answer:
Step-by-step explanation:
The circular thread milling cutter ZBGF H allows you to carry out drilling and thread milling without tool change and in only one operation.
This solid carbide tool stands for process reliable milling of metric internal threads and insert threads (EG) up to 2,5xD. The thread milling cutter feels at home even in difficult to machine materials up to 63 HRC.
Due to the manufacturing process an exact thread depth of up to 1,5xP to the hole bottom is possible. The short milling chips produced during machining are removed in the direction of the shank. The ZBGF has straight flutes and is left-hand cutting which are the best prerequisites for achieving high tool life in synchronous milling.
The tool benefits from the properties of the BA-coating. This coating is wear resistant, extremely heat resistant and shows a high hardness. In series of tests, BASS was able to prove that the geometry of the milling cutter in combination with the BA-coating is superior to a milling cutter type with
internal coolant.
With a ZBGF, a range of different thread dimensions with the same pitch can be realized, e. g. M10 and M12x1,5. It is used in varied materials, all tolerances and for the production of left-hand or right-hand threads.
For its application, the ZBGF requires the same conditions that are already known from conventional thread milling.

You can keep a product the same if you divide one factor by 10 and multiply the other factor by 10:
8.91×10² = (8.91/10)(10×10²) = 0.891×10³
I like to "pre-scale" the numbers in a problem like this so that the product comes out in scientific notation with no adjustment needed. That is, the product of the two mantissas is a number between 1 and 10.
Here, you can tell the product of 8.91 and 3.3 will be more than 24, so scaling will be necessary. It is convenient to scale the larger mantissa to be less than 1 so the product comes out less than 10. That is why we made it 0.891×10³.

The equation representing visual models is z+1/5=3/5.
Since it is given in the question that the hanger image represents a balanced equation therefore equating LHS with RHS it can be written as follows.
LHS = 1/5 + z
RHS = 3/5+ z
Equating both the equations it can be written as
LHS = RHS
1/5+z=3/5

(b). What is the range of b_{2} the right hand side of the second constraint (currently 3) for which this BFS remains optimal:
(c). What is the dual price of the second constraint?
Answers
(a) The range of c₁ (the objective coefficient of x₁) for which this BFS remains optimal is c₁ ≤ 2.
(b) The range of b₂ (the right-hand side of the second constraint) for which this BFS remains optimal is 3 ≤ b₂ < 4.
(c) The dual price of the second constraint is 0.
(a) The optimality condition for a linear programming problem requires that the objective coefficient of a non-basic variable (here, x₁) should not increase beyond the dual price of the corresponding constraint. In this case, the dual price of the second constraint is 0, indicating that increasing the coefficient of x₁ will not affect the optimality of the basic feasible solution. Therefore, the range of c₁ for which the BFS remains optimal is c₁ ≤ 2.
(b) The range of b₂ for which the BFS remains optimal is determined by the allowable range of the corresponding dual variable. In this case, the dual price of the second constraint is 0, implying that the dual variable associated with that constraint can vary within any range. As long as 3 ≤ b₂ < 4, the dual variable remains within its allowable range, and thus, the BFS remains optimal.
(c) The dual price of a constraint represents the rate of change in the objective function value per unit change in the right-hand side of the constraint, while keeping all other variables fixed. In this case, the dual price of the second constraint is 0, indicating that the objective function value does not change with variations in the right-hand side of that constraint.

Answers
To approximate the surface area of one slipcover for Davea's topiaries, we need more information regarding the shape and dimensions of the topiaries.
To calculate the surface area of a slipcover, we need information about the shape and dimensions of the topiary. Depending on the specific shape, whether it is a cone, cylinder, or other geometric form, the surface area formula will differ. For example, if the topiary is a cone, the surface area formula would involve the radius and slant height of the cone. If it is a cylinder, the surface area formula would involve the radius and height of the cylinder. Without these details, it is impossible to provide an accurate estimate of the surface area of the slipcover. However, in general, the slipcover would cover the entire surface of the topiary, excluding the base, to provide adequate protection against frost.
