Find The Volume Of The Composite Solid (STEP BY STEP PLEASE) 25 POINTS

Answers

Answer 1

The composite solid has a volume equal to 2268π cubic feet.

How to determine the volume of a composite solid

In this problem we have the case of a solid as a result of the combination of a cylinder and a hemisphere. The volume formulas for the cylinder and the hemisphere are, respectively:

Volume of cylinder

V = π · r² · h

Volume of hemisphere

V = (2π / 3) · r³

Where:

r - Radius, in feeth - Height, in feet

Volume of the composite solid:

V' = π · r² · h + (2π / 3) · r³

If we know that r = 9 ft and h = 22 ft, then the volume of the composite solid is:

V' = π · (9 ft)² · (22 ft) + (2π / 3) · (9 ft)³

V' = 2268π ft³

The volume of the composite solid is equal to 1053π cubic feet.

An electronics store receives a shipment of 30 graphing​ calculators, including 7 that are defective. Four of the calculators are selected to be sent to a local high school. How many of these selections will contain no defective​ calculators?

Answers

Based on probability, three of the four selected calculators will contain no defective.

What is the probability?

Probability refers to the likelihood or chance that an expected outcome occurs in the midst of many possible outcomes or events.

Probability is zero when uncertain and one when 100% certain.  Otherwise, probability lies between zero and one, which yields a fractional value denoted by decimals, percentages, or fractions.

The number of shipped graphing calculators = 30

The number of defective calculators = 7

The probability of defective calculators = 0.233 (7/30)

The probability of no defective calculators = 0.767 (1- 0.233)

The number of calculators to be sent to a high school = 4

The number of these that will contain no defective calculators = 3.068 (4 x 0.767)

= 3

Thus, the local high school will probably receive 3 non-defective units.

Here we have give that researchers are testing a new diagnostic tool designed to identify a certain condition. the null hypothesis of the significance test is that the diagnostic tool is not effective in detecting the condition. for the researchers, the more consequential error would be that the diagnostic tool is not effective, but the significance test indicated that it is effective.

And we need to find in which of the following should the researchers do to avoid the more consequential error.

According to the given question, the null hypothesis is that the new diagnostic tool is not effective in detecting the condition.

Here the more consequential error described is that the diagnostic tool is not effective, but the significance test indicated that it is effective. This is a type I error.

And in Hypothesis testing, a type I error involves rejecting the null hypothesis and accepting the alternative hypothesis when in reality, the null hypothesis is true.

Therefore, it involves saying there is significant evidence to show that the new diagnostic tool is effective in detecting the condition when in reality, it isn't.

When the level of significance (α) of a hypothesis test directly gives the probability of a type I error. So, by setting it lower, we reduce the chances of a type I error.

Answers

The length of the segment of the MN is 10 units, by using the midpoint formula and distance formula.

Distance Formula

The algebraic phrase is known as the distance formula, which provides the distances between two places in terms of their coordinates (see coordinate system). The distance formulas for points in rectangular coordinates in two- and three-dimensional Euclidean space are based on the Pythagorean theorem.

Since M is the midpoint of side AB and N is the midpoint of side AC, we can use the midpoint formula to find the coordinates of points M and N.

Midpoint Formula: (x₁ + x₂)/2, (y₁ + y₂)/2

For M:

(A x + B x)/2, (A y + B y)/2

= (18 + 0)/2, (0 + 0)/2

= 9, 0

For N:

(A x + C x)/2, (A y + C y)/2

= (18 + 20)/2, (0 + 0)/2

= 19, 0

Step 4: Now that we have the coordinates of M and N, we can use the distance formula to find the length of the segment MN.

Distance Formula: √((x₂ - x₁)² + (y₂ - y₁)²)

For MN:

√((19 - 9)² + (0 - 0)²)

= √(100)

= 10

Therefore, the length of the segment MN is 10 units.

Consider The Following Problem: Min - X1 + X2 S.T. X1 + X3 – 2xı = 0 (X1, X2) E X Where X Is The Convex Combination Of The Points (-1,0), (0,1) (1,0), (0,-1). a. find the optimal solution graphically b. Do the frizt john or KTT condition hold the optimal solution in part (a)? if not explain in the term of the theorem 4.3.2.and 4.3.7 in the textbook.

Answers

The objective function is -x1 + x2. Also, the multiplier associated with the x1 + x3 - 2x1 = 0 constraint is 0,  satisfies the KKT condition.

To find the optimal solution graphically, first plot the points (-1,0), (0,1), (1,0), and (0,-1) on the coordinate plane. These points form a square. The objective function for this problem is to minimize -x1 + x2. So we need to find the point on the square that is as low as possible on the y-axis (because the y-axis represents x2).

The constraint in question is x1 + x3 - 2x1 = 0, which can be rewritten as x3 = 2x1. Since x1 and x3 are variables, this represents a line on the coordinate plane. You can draw this line by selecting two points on this line and connecting them with a line. For example, you can select points (-1, -2) and (1, 2). These points lie on the line x3 = 2x1 and the connecting lines are plotted in the coordinate plane.

We can find the best solution by finding the point on the square that is the lowest possible on the straight line of y-axis and x3 = 2x1. The point that satisfies both of these conditions is the point (0,-1). This is the best solution for your problem.

To answer the second part of the question we need to determine whether the Fritz-John condition or the KKT condition is the optimal solution. The Fritz-John condition is an optimality requirement involving an objective function and problem constraints. A KKT condition is a necessary and sufficient condition for optimality that includes an objective function, a constraint, and a multiplier associated with the constraint.

The Fritz-John condition is not considered optimal for this problem. This is because the optimal solution does not satisfy the condition x1 + x3 – 2x1 = 0. The point (0,-1) does not satisfy the condition because it is not on the line x3 = 2x1.

KKT conditions are considered to be the best solution. This is because the point (0,-1) is a legal point (it lies on the square representing the legal region) and the global minimum of the objective function is -x1 + x2. Also, the multiplier associated with the x1 + x3 - 2x1 = 0 constraint is 0, which satisfies the KKT condition.

line m and point p are graphed on the coordinate grid below. which equation represents a line that passes through point p and is parallel to line m?

Answers

The equation of the graphed on the coordinate grid parallel to line M y = x and passing through the point P(4, -7) is equal to y = x - 11.

As given in the question,

Equation of the line M is given by :

y = x

Slope of the line M by comparing it with standard equation of the line with slope m is given by :

y = mx + c

Equation of the line M is y = x

Here m = 1

Slope of the required line is m₁ = 1 as it is parallel to line M

Equation of the required line which passes through ( x₁ , y₁) = ( 4, -7) with slope m₁ = 1 is given by:

y - y₁ = m₁( x - x₁)

⇒ y + 7 = 1( x - 4)

⇒ y= x - 4 -7

⇒ y= x - 11

Therefore, the equation of the required line which is parallel to line M and passing through point P is equal to y = x - 11.

Line M is graphed on the coordinate grid. y = x. Which equation can be used to represent a line parallel to M passing through the point P(4, -7)?

A.  x = 4          B. x = -7             C. y = -7              D. y = 4

Answers

This steady-state number of fish is ...  1200 - 1058 = 142 . . . . below the original carrying capacity

The differential equation is modified by adding a -100 fish per year constant term:

 (dN)/(dt) = (0.4)/(1200)N(1200-N) -50

The steady-state value of the fish population will be when N reaches the value that makes dN/dt = 0.

 (0.4/1200)(N)(1200-N) -50 = 0

 N(N-1200) = -(50)(1200)/0.4) . . . . rewrite so N^2 has a positive coefficient

 N^2 -1200N + 600^2 = -150,000 +600^2 . . . . complete the square

 (N -600)^2 = 210,000 . . . . . simplify

 N = 600 + √210,000 ≈ 1058

This steady-state number of fish is ...

 1200 - 1058 = 142 . . . . below the original carrying capacity

a brokerage firm keeps track of the total money spent on tesla stocks by their clients each day of the week, t(t). the function t(t) can be expressed as t(t)

Answers

a brokerage firm keeps track of the total money spent on tesla stocks by their clients each day of the week is C(T) = $730 + $25T

R(T) = $35T

T = 193 transact

C = cost ; R = revenue ; T = number of transactions

Amount paid per transaction = $25

Cost keeping office open = $730

Amount collected on each transaction = $35

(a) Find a formula that gives C as a function of T.

C(T) = Cost of keeping office open + (cost per transaction × number of transactions)

C(T) = $730 + $25T

(b) Find a formula that gives R as a function of T.

R(T) = (Amount collected per transaction * number of transactions)

R(T) = $35T

(c) Find the number of daily transactions that are needed to make the revenue $1200 more than the cost.

R = C + 1200

Substitute the value of R and C into the equation:

35T = 730 + 25T + 1200

35T - 25T = 730 + 1200

10T = 1930

T = 1930 / 10

T = 193 transactions

which of the variables listed above would best be displayed graphically using a bar graph? mark all that apply. group of answer choices number of minutes of exposure to secondhand smoke per day currently diagnosed with asthma race years of education gender

Answers

The two possible variables design are; "COHORT STUDY" and "CROSS-SECTIONAL STUDY".

Cohort study design is an observational study in which people who receives a particular treatment or are under a particular condition, are been observed and studied. This type of research model also allows a researcher to compare people affected by a condition to people unaffected by the same conditions.

The investigator is likely to use the cohort design because it will help in studying the children that are always exposed to smoke, and to observe the affected and unaffected children.

The CROSS-SECTIONAL design is an observational study in which a specific population are studied at a particular time. This type of research allows the researcher to study the difference in that population at a time interval.

This study design is likely to be used by the investigator, because it will help the investigator to determine the amount of secondhand smoke each child inhale at a particular time. It will also help the investigator to know the outcome of each child after 5years
