To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer 1

Answer:

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

$\delta d$ . The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

$\delta r$ . The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).

The sum of the three interior angles of a triangle is 180 degrees.(there can be more than 1 answer)
please help

a.) x · y · z = 180°
b.) x + y + z = 180°
c.) 3a = 180°
d.) a + 55° + 36° = 180°
e.) x³ = 180°

Answers

It can be b), c) and d).

b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.

c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.

d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.

a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)

James Smith and Bill Ross purchased a property together for their business venture with stated proportionate interest of 1/3 and 2/3 respectively without the right of survivorship. Each of them wants his share to be inherited by his wife. They are a partnership and not a corporation. James and Bill most likely took title as:_________A) joint tenants.
B) tenants in common.
C) in severalty.
D) a general partnership.

Answers

Answer:

B) tenants in common.

Explanation:

There were two men, first was James Smith, and second was Bill Ross who bought a property mutually for their business venture by declared proportionate interest of 1/3 as well as 2/3 sequentially without the right regarding survivorship. Both of them want their shares to be acquired by their spouses'. Both hold a partnership but not a company. James, as well as Bill, most likely took the title as tenants in common.Because tenants in common possess versatility in whence they divide control as well as assign the rights concerning survivorship. Joint tenants, on the different hand, keep the property in similar shares while a common partnership is a business unit serving separate sharers. Severalty, as asserted beforehand, is individual ownership.

A map is drawn using a scale of 80 mi to 1 cm. On the map , the two cities are 7.5 cm apart. What is the actual distance between the two cities ??

Answers

we know that
scale =measure in the map/measure in the actual
measure in the actual=measure in the map/scale
scale=1 cm/ 80 mi
for
measure in the map=7.5 cm
measure in the actual=?
measure in the actual=7.5 /(1/80)-----> 7.5*80-----> 600 mi

the answer is
the actual distance between the two cities is 600 miles
