Answer: 170 degree difference

Answer:

The difference between two numbers canbbe obtained substracting.

The diffence between 130 °F and -40 °F would be the same as substracting both numebrs (we should put an absolute value as the difference is positive).

130 - (-40) = 130 + 40 = 170 ° F

So the difference is of 179 °F

Answer:

0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Flagged as future criminal

Event B: Commits a crime.

In the year 2054 the government estimates that out of every 1,000,100 citizens 1,000,000 will remain law-abiding, and 100 will eventually commit a crime.

This means that [tex]P(B) = \frac{100}{1000100} = 0.00009999[/tex]

If a person is going to commit a crime, the Precogs identify that person correctly 99.999% of the time

This means that [tex]P(A|B) = 0.99999[/tex]

Probability of being identified as a criminal:

0.99999 out of 0.00009999(identified and commits crime).

(1-0.99999) out of (1-0.00009999) (identifed and does not commits crime). So

[tex]P(A) = 0.99999*0.00009999 + (1-0.99999)*(1-0.00009999) = 0.000109988[/tex]

What is the probability that a person flagged as a future criminal by the Precogs will actually commit a crime

[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.00009999*0.99999}{0.000109988} = 0.9091[/tex]

0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime

Answer:

1/27 cubic in.

Step-by-step explanation:

1/3*1/3*1/3= 1/27

The volume of the cube if, its edge length is 1/3 inch is 1 / 27 inches³.

The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.

Given:

The length of the edge = 1 / 3 inches,

Calculate the volume of the cube as shown below,

The volume of the cube = The length of the edge × The length of the edge × The length of the edge

The volume of the cube = 1 / 3 × 1 / 3 × 1 / 3

The volume of the cube = 1 / 27

Thus, the volume of the cube is 1 / 27 inches³.

#SPJ2

Answer:

The population decrease by 17%.

Step-by-step explanation:

This is because 66,400 is 83% of 80,000.

100%-83%= 17%

Therefore, the percentage of the population that decreased was 17%

Answer:

(a) [tex]x = 60[/tex]

(b) [tex]x = 2.64[/tex]

(c) [tex]x=15[/tex]

Step-by-step explanation:

Solving (a):

[tex]\frac{1}{4}x + \frac{2}{5}x = 39[/tex]

[tex]\frac{x}{4} + \frac{2x}{5} = 39[/tex]

Take LCM

[tex]\frac{13x}{20} = 39[/tex]

Multiply through by 20

[tex]20 * \frac{13x}{20} = 39 * 20[/tex]

[tex]13x = 39 * 20[/tex]

[tex]13x = 780[/tex]

Solve for x

[tex]x = 780/13[/tex]

[tex]x = 60[/tex]

Solving (b):

[tex]0.6x + 0.5x = 2.9[/tex]

This gives:

[tex]1.1x = 2.9[/tex]

Solve for x

[tex]x = \frac{2.9}{1.1}[/tex]

[tex]x = \frac{29}{11}[/tex]

[tex]x = 2.64[/tex]

Solving (c):

[tex]\frac{3}{5}x = 9[/tex]

Multiply both sides by [tex]\frac{5}{3}[/tex]

[tex]\frac{5}{3}*\frac{3}{5}x = 9 * \frac{5}{3}[/tex]

[tex]x = 9 * \frac{5}{3}[/tex]

[tex]x = \frac{9 *5}{3}[/tex]

[tex]x = \frac{45}{3}[/tex]

[tex]x=15[/tex]

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Both criteria require that two pairs of angles be congruent, but for congruence, you also need to know that the included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape. Thus option A is correct.

According to the Angle-Angle (AA) criterion, two triangle being considered comparable if "two angles from one triangle are equally equivalent to two angles of some other triangle."

According to the ASA congruence rule, two triangles are compatible when their two covered sides and two contained angles are equivalent to each other. However, thus according to AAS, if two triangles have two angles as well as one side that are identical to one another, then perhaps the triangles are congruent.

Because ASA and AAS are identical since it follows that if two images in one triangle are equal with two angles in another, therefore the third angles must likewise be identical. Therefore, option A is the correct option.

10d + 5.50 = x (the total cost)

Answer:

a) 0.0002 = 0.02% probability that all are silver.

b) 0.0033 = 0.33% probability that 5 are red and 2 are black

c) 0.0345 = 3.45% probability that 4 are red and the rest are silver

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the cars were selected is not important, so we use the combinations formula.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

(a) all are silver

Desired outcomes:

7 silver cars, from a set of 9. So

[tex]D = C_{9,7} = \frac{9!}{7!(9-7)!} = 36[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{36}{170544} = 0.0002[/tex]

0.0002 = 0.02% probability that all are silver.

(b) 5 are red and 2 are black

Desired outcomes:

5 red, from a set of 8

2 black, from a set of 5

[tex]D = C_{8,5}*C_{5,2} = \frac{8!}{5!(8-5)!}*\frac{5!}{2!(5-2)!} = 56*10 = 560[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{560}{170544} = 0.0033[/tex]

0.0033 = 0.33% probability that 5 are red and 2 are black

c) 4 are red and the rest are silver

Desired outcomes:

4 red, from a set of 8

3 silver, from a set of 9

[tex]D = C_{8,4}*C_{9,3} = \frac{8!}{4!(8-4)!}*\frac{9!}{3!(9-3)!} = 70*84 = 5880[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{5880}{170544} = 0.0345[/tex]

0.0345 = 3.45% probability that 4 are red and the rest are silver

Answer:

true that trump = worst president

Step-by-step explanation:

Answer:

1.)A rhombus is a quadrilateral with four equal-length sides and opposite sides parallel to each other. All rhombuses are parallelograms, but not all parallelograms are rhombuses.

2.) When all 4 sides of a rectangle are equal then the rectangle is a square. So, a rectangle can also sometimes be a square

3.)If you have a rhombus with four equal interior angles, you have a square. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.

4.)Yes. Every square is a closed figure, and every square has 4 straight sides, so every square is a quadrilateral.

Answer:

sigma should be used

Step-by-step explanation:

Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.

The above given is for sample of 27 size.

For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.

But once population std deviation is given, we use only that as that would be more reliable.

So here we can use population std deviation 1.4 only.

If population std deviation is used we can use normality and do Z test
