you roll two fair dice. find the probability that the first die is a 6 given that the minimum of the two numbers is a 4.

The correct unit prices are,

1. 20 for $1.56 = A. 7.8 cents each

2. $3.78 for 6 = B. 63 cents each

3. 2 1/2 for one dollar = C. 40 cents each

4. 5 at $3.90 = D. 78 cents each

5. 1 1/2 for $1.58 = E. $1.05 each

From the given cases;

1. Given that 20 things cost $1.56,

So, the price of one item is = $1.56/20

                                             = $0.078.

Cents for every dollar,

So, $0.078 equals $0.078 * 100

                              = 7.8 cents.

2. Since the cost of six products is $3.78, 

The cost of one item is 3.78/6

                                    =  $0.63.

Cents for every dollar,

Thus, $0.63 equals $0.63 * 100

                               = 63 cents.

3. 2 1/2 = 5/2 = 1 as a price

So, the price of one item is equal to 2/5 of a dollar, or 100 cents.

$2/5 equals 2/5 * 100, or 40 cents.

4. Given that the price of 5 things is $3.90

The price of 1 item is 3.90/5, or $0.78.

Cents for every dollar

So, $0.78 = $0.78 * 100 = 78 cents.

5. Cost of 1 1/2 = 3/2 = $1.58

So, cost of 1 item =  1.58/(3/2)

                            = 1.05

Hence, these are the solutions for the given cases.

Answer:

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

All the sides have equal lengths.  Set the two sides equal to each other and solve for y

[tex]\frac{5}{4}[/tex]y + 1 = [tex]\frac{7}{3}[/tex]y  -2  I am going to clear the fractions by multiplying through by 12

[tex](\frac{12}{1})[/tex][tex]\frac{5}{4}[/tex] y + (12)(-1) = [tex](\frac{12}{1})[/tex][tex]\frac{7}{3}[/tex] y - (12)2

15y - 12 = 28y - 24  Subtract 15y from both sides

-12 = 13y - 24  Add 24 to both sides

12 = 13y  Divide both sides by 13

[tex]\frac{12}{13}[/tex] =  y

Plug 12/13 into the expression for either side to find the length of BC.  All the sides have the same length

[tex]\frac{7}{3}[/tex][tex](\frac{12}{13})[/tex]  -  2

[tex]\frac{28}{13}[/tex] - [tex]\frac{26}{13}[/tex] = [tex]\frac{2}{13}[/tex]

There is not evidence that the population mean waiting time is different from 3.6 ​minutes.

What is the p-value?

A statistical measurement known as a p-value is employed to check a hypothesis' validity against actual data. A p-value calculates the likelihood of getting the outcomes that were observed, presuming that the null hypothesis is correct. The statistical significance of the difference that was found increases with decreasing p-value.

From the question, we know that the size (n), the mean (x), and the standard deviation (s) of the sample are 81, 3.45 minutes and 0.9 minutes. Additionally, we are going to decide if the waiting time is different or not from 3.6 minutes, so the null and alternative hypotheses are:

H0: m=3.6

H1:  m≠3.6

Where m is the mean of the population.

Then, we don't need to be concerned about the shape of the population distribution because the value of the n is bigger than 30 and we can use the statistic z as:

[tex]z = \frac{x-m}{\frac{a}{\sqrt{n} } }[/tex]

So, replacing the values, the test statistic is:

[tex]z = \frac{3.45 - 3.6}{\frac{0.9}{\sqrt{81} } }[/tex]

= 2.50

On the other hand, the p-value for this test is calculated as:

p-value = 2P(z >2.50) = 2(0.0668) = 0.134

Taking into account that the p-value is bigger than the level of significance 0.01, the null hypothesis is not rejected, and there is not evidence that the population mean waiting time is different from 3.6 ​minutes.

If the bond angle between two adjacent hybrid orbitals is 180 degree then the hybridization  is sp hybridization , it forms linear molecules with an angle of 180°.

Hybridization is a theory that is used to explain certain molecular geometries that would have not been possible otherwise.

In sp hybridization, the s orbital of the excited state carbon is mixed with only one out of the three 2p orbitals. It is called sp hybridization because two orbitals (one s and one p) are mixed.

The resulting two sp hybrid orbitals are then positioned at 90 degree and 180 degree, respectively, with the two 2p unhybridized orbitals:

Process of elimination.

A is incorrect because 6 out of 10 people is 60 percent.

C is wrong because if you consider just half (50 percent) of 65, you'll get 32.5 . In order to get 65 percent, C would have to be over 32.5, and 10 is not.

D is wrong because once again, half (50 percent) of 13 is 6.5 and in order to get 65 percent, D would have to be over 6.5, and 5 is not.

Answer:

  sum = 65

Step-by-step explanation:

You want the sum of the set of 5 consecutive positive integers such that the sum of the even integers in the set is 26.

The sum of even integers will be a multiple of 3 if the middle integer of the set is even. Here, that sum is 26, not a multiple of 3. Hence the middle integer of the set is 26/2 = 13, and the sum of the set is 13·5 = 65.

The sum of the five integers is 65.

__

Additional comment

When working "consecutive integer" problems, it is often useful to think in terms of the average of the integers, the middle one of an odd-length set, or the number halfway between the two middle ones of an even-length set.

A set of 5 integers will have either 3 odds and 2 evens, or 3 evens and 2 odds. The set here obviously does not have 3 even integers (whose sum would be 3 times the middle one).

The set is s = {11, 12, 13, 14, 15}. 10 is not in the set, but 11 is. The sum of evens is 12+14=26.

Equation 1 needs to be multiplied with + 2

Equation 2 needs to be multiplied with  + 5.

Step-by-step explanation:

Here, the given system of equation is given as:

Equation 1 : 6 x − 5 y = -4

Equation 2: 4 x + 2 y = 28

Here, in equation 1, the coefficient of y  = - 5

Also, in the equation 2, the coefficient of  y = + 2

Now, in order to eliminate the y coefficients,

Coefficient  of y in  1  =   -  Coefficient of y in  2

Now, to make -5 and  + 2 to eliminate each other,

Multiply -5 with 2, we get            -5 x 2  = -10

And Multiply the coefficient + 2 with 5, we get   +2 x 5  = + 10

The new coefficient of y is equation 1 = - 10 y

The new coefficient of y in equation 2  = + 10 y

They will cancel out each other, when both equations are ADDED.

Hence, equation 1 needs to be multiplied with + 2

and the equation 2 needs to be multiplied with  + 5.

What are Similar Triangles ?

Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. We denote the similarity of triangles here by ‘~’ symbol.

In the given figure below, two triangles ΔABC and ΔXYZ are similar only if,

i)       ∠A = ∠X, ∠B = ∠Y and ∠C = ∠Z

ii)       AB/XY = BC/YZ = AC/XZ (Similar triangles proportions)

Hence, if the above-mentioned conditions are satisfied, then we can say that ΔABC ~ ΔXYZ

It is interesting to know that if the corresponding angles of two triangles are equal, then such triangles are known as equiangular triangles. For two equiangular triangles we can state the Basic Proportionality Theorem (better known as Thales Theorem) as follows:

For two equiangular triangles, the ratio of any two corresponding sides is always the same

Given that ,

For ΔABC , Length of shorter side = 3, Length of medium side = 4 , Length of longer side = 6.

Now,

For ΔDEF ,

Scale Factor = 2

Length of shorter side = 2*3 = 6, Length of medium side =2*4 = 8 , Length of longer side =2*6 = 12.

the standard deviation of the sample means:

σ(x) = σ/[tex]\sqrt{n}[/tex]

The central limit theorem states that if you have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement text annotation indicator, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large (usually n > 30). If the population is normal, then the theorem holds true even for samples smaller than 30. In fact, this also holds true even if the population is binomial, provided that min(np, n(1-p))> 5, where n is the sample size and p is the probability of success in the population. This means that we can use the normal probability model to quantify uncertainty when making inferences about a population mean based on the sample mean.

For the random samples we take from the population, we can compute the mean of the sample means:

Answer:

  (2)  11

Step-by-step explanation:

You want the area of the triangle with vertices (1, 3), (3, -1), and (-2, -2).

Pick's theorem says the area of a figure drawn on a grid can be found by counting the grid points on the boundary (b) and the interior grid points (i). Then the area is ...

  A = (b/2) +i -1

This figure has a boundary grid point at (2, 1) in addition to the three vertices. So, b = 4.

There are 10 interior grid points, a number that can be arrived at by counting them. The numbers in each row, starting from the bottom, are 4, 3, 2, 1.

Then the area is ...

  A = (4/2) +10 -1 = 11

The area of the triangle is 11 square units.

The area can be computed from the coordinates by the formula ...

  A = 1/2|x1(y2 -y3) +x2(y3 -y1) +x3(y1 -y2)|

  A = 1/2|1(-1 -(-2)) +3(-2 -3) +(-2)(3 -(-1))| = 1/2|1 -15 -8| = 11

The area is 11 square units.

The triangle can be bounded by a square 5 units on a side. The triangle area is smaller than the square area by the sum of the three triangles cut from the corners of the square. Clockwise from left, those triangle areas are ...

  1/2(5·3) +1/2(4·2) +1/2(1·5) = 1/2(15 +8 +5) = 14

Then the area of the triangle of interest is ...

  5² -14 = 11

The area of the triangle is 11 square units.

The angle the bottom edge makes with the horizontal is ...

  arctan(1/5) ≈ 11.3099°

and the length of that edge is ...

  5/cos(11.3099°) ≈ 5.099

The angle the left side makes with the horizontal is ...

  arctan(5/3) ≈ 59.0362°

and the length of that edge is ...

  3/cos(59.0362°) ≈ 5.831

The area of the triangle with sides 'a' and 'b' and angle C between them is ...

  Area = 1/2(ab·sin(C)) = 1/2(5.099·5.831·sin(59.0362° -11.3099°)) = 11

The area of the triangle is 11 square units.

Side lengths could also be determined using the Pythagorean theorem, and the angle between any two of them could be found using the Law of Cosines.

Heron's formula could be used to find the area from the three side lengths.
