your company makes game parts using 3-d printers. one customer wants a circular game coin that is 2.0 centimeters across and 0.5 centimeters thick, as shown below. you need to estimate the amount of plastic you will need for each batch of 50 coins. how many cubic centimeters is that, rounded up if necessary to be a multiple of 10 cubic centimeters?
Answers
The amount of plastic needed for each batch of 50 coins is equal to the volume of 50 coins that is 80 cu.cm.
The diameter of the coin is 2.0 cm.
As radius is half of the diameter, so its radius will be 1.0 cm.
It is given that the coin is circular in shape, so the area of the circular surface will be πr² = 3.14 × 1² = 3.14 sq. cm. (π = 3.14)
The thickness of the coin is 0.5 cm, which will be considered as the height of the coin.
So, the volume of each coin will be = 3.14 × 0.5 = 1.57 cu. cm.
Therefore, the plastic needed for the batch of 50 coins is,
1.57 × 50 = 78.5 cu.cm and in multiple of 10 it will be 80 cu.cm.

Answers
Answer: P(7)=P(5)=12
Step-by-step explanation:
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.
The total number of the sweets will be given as,
Total events = 7 + 5 = 12
The probability of choosing milk will be given as,
P = (7/12)
P = 0.5833
The probability of choosing not to milk will be given as,
P = (5/12)
P = 0.4167
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

• Mg : 24.305 g/mol
• S : 32.06 g/mol
• O : 15.999 g/mol
• H : 1.008 g/mol
Then MgSO₄•7H₂O has a total molar mass of about 246.466 g/mol. 7H₂O has a total molar mass of about 126.105 g/mol, so it makes up about 0.5117 or 51.17% of the total mass.
Now, 0.01132 mol of MgSO₄•7H₂O has a mass of

\(AB=12\) (sides opposite congruent angles in a triangle are congruent)
\(AB=36\) (segment addition postulate)
The value of AB = 36
What is an isosceles triangle?An isosceles triangle is a triangle with base angles equal with any two sides equal.
Analysis:
∠ACB = 120
ABC is isosceles, so ∠CAB = ∠CBA = x
x + x + 120 = 180 ( sum of angles in Δ ABC)
2x = 60
x = 30
∠AMC = 180 - ∠BMC( angles on a straight line)
= 180 - 60 = 120
∠ACM = 180 - (30 + 120) = 180 - 150 = 30°
∠MCB = 90°
using sine rule,
12/sin 30 = AM/ sin 30
AM = 12
MB/sin 90 = 12/sin30
MB sin 30 = 12 sin 90
MB = 12/sin 30 = 12/0.5 = 24

Answers
If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113
To find the value of P(B|A), follow these steps:
The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113.

If you have a short position in a bond futures contract, you expect that bond prices will ________. Question 16 options: 1) Rise 2) Fall 3) not change 4) fluctuate
Answers
If you have a short position in a bond futures contract, you expect that bond prices will fall.
This is because when you have a short position in a bond futures contract, you are essentially betting that the price of the underlying bond will decrease over time.
As bond prices fall, the value of the bond futures contract will also decrease, allowing you to buy it back at a lower price and pocket the difference as profit.Bond prices are affected by a number of factors, including interest rates, inflation expectations, and market demand. When interest rates rise, bond prices tend to fall, as investors demand higher yields to compensate for the increased risk. Similarly, when inflation expectations rise, bond prices tend to fall, as investors demand higher yields to protect against the eroding value of their investment.In general, bond prices and bond futures contracts tend to move in opposite directions. When bond prices rise, the value of a short position in a bond futures contract will decrease, and vice versa. This relationship allows investors to hedge against fluctuations in bond prices by taking opposite positions in the bond market and the futures market.Know more about bond prices

Answers
Yes, two samples can have the same range but different means. The range of a dataset is a measure of the spread or dispersion and is determined by the difference between the maximum and minimum values. The mean, on the other hand, represents the average value of the dataset.
To illustrate this concept, let's consider two different samples:
Sample 1: 1, 5, 6, 9, 10
Sample 2: 2, 4, 7, 8, 10
Both samples have a range of 9 (10 - 1).
However, the means of the samples are different. The mean of Sample 1 is
(1 + 5 + 6 + 9 + 10) / 5 = 6.2,
while the mean of Sample 2 is
(2 + 4 + 7 + 8 + 10) / 5 = 6.2.
Despite having the same range, the means differ between the two samples.
The range only considers the extreme values of the dataset, whereas the mean takes into account all values and provides an average measure. It is possible for the individual values within the samples to be distributed differently, resulting in different means, even if the range remains the same.
Therefore, the range and the mean are distinct measures that capture different aspects of the dataset. While it is possible for two samples to have the same range, they can still have different means based on the specific values and their distribution within each sample.

you can rent time on computers at the local copy center for a $10 setup charge and an additional $2 for every 5 minutes. how much time can you rent for $25?
Answers
You can rent time on computers at the local copy center for 35 minutes with $25.
To find out how much time you can rent for $25 at the local copy center, follow these steps:
1. Subtract the $10 setup charge from the total amount you have: $25 - $10 = $15.
2. Now you have $15 left for renting time on the computers. Since it costs $2 for every 5 minutes, you need to find out how many 5-minute increments can be covered by $15.
3. Divide the remaining amount by the cost per 5-minute increment: $15 / $2 = 7.5. Since you can't have half an increment, round down to 7.
4. Multiply the number of 5-minute increments by the time per increment: 7 * 5 = 35 minutes.
So, you can rent time on computers at the local copy center for 35 minutes with $25.

Find equations of the normal plane and osculating plane of the curve at the given point.
x = 5t, y = t^2
, z = t^3
; (5, 1, 1)
(a) An equation for the normal plane is
O 5x + 2y + 3z = -30
O 30x + 2y + 3z = 30
O 5x + 3y + 2z = 30
O 5x + 2y + 3z = 30
O 5x + 2y - 3z = 30
b) An equation for the osculating plane is
O 3x - 15y + 5z = 5
O 3x - 15y + 5z = -5
O x - 15y + 3z = 5
O 3x - y + 3z= 5
O 3x - 15y + 5z = 15
Answers
Answer:
Step-by-step explanation:
To find the normal plane and osculating plane, we first need to find the required derivatives.
x = 5t, y = t^2, z = t^3
dx/dt = 5, dy/dt = 2t, dz/dt = 3t^2
So, the velocity vector v and acceleration vector a are:
v = <5, 2t, 3t^2>
a = <0, 2, 6t>
Now, let's evaluate them at t = 1 since the point (5, 1, 1) is given.
v(1) = <5, 2, 3>
a(1) = <0, 2, 6>
The normal vector N is the unit vector in the direction of a:
N = a/|a| = <0, 1/√10, 3/√10>
Using the point-normal form of the equation for a plane:
normal plane equation = 0(x-5) + 1/√10(y-1) + 3/√10(z-1) = 0
Simplifying this equation we get:
5x + 2y + 3z = 30
The osculating plane can be found using the formula:
osculating plane equation = r(t) · [(r(t) x r''(t))] = 0
where r(t) is the position vector, and x is the cross product.
At t = 1, the position vector r(1) is <5, 1, 1>, v(1) is <5, 2, 3>, and a(1) is <0, 2, 6>.
r(1) x v(1) = <-1, 22, -5>
r(1) x a(1) = <12, -6, -10>
v(1) x a(1) = <-12, 0, 10>
Substituting these values into the formula, we get:
osculating plane equation = (x-5, y-1, z-1) · <12, -6, -10> = 0
Simplifying this equation we get:
3x - 15y + 5z = 5
Therefore, the equations for the normal plane and osculating plane at (5, 1, 1) are:
(a) 5x + 2y + 3z = 30
(b) 3x - 15y + 5z = 5
