The oxidation number of the nitrogen in the ammonia is negative 3. Then the correct option is A.

The number of allocated elements in a chemical combination is termed an oxidation number. The oxidation number is generally the count of the number of electrons that a molecule or atom shares, loses, or gains during bond formation.

The compound is NH₃ is given.

The chemical equation can be written as

NH₃ = N³⁻ + 3 H⁺

Thus, the oxidation number of the nitrogen in the ammonia is negative 3. Then the correct option is A.

Answer:

23/10

Step-by-step explanation:

To find the unit rate divide 84 by 36

84 ÷ 36 = 2.3

To convert 2.3 to a faction

2.3 = 2.0 + 0.3

0.3 = 3/10

3/10 + 2 = 2 3/10

2 3/10 = 23/10

Answer:

There is a 38% chance at least 1 was blue

Step-by-step explanation:

there are 8 marbles total 3 being blue. 3/8= .375 = 38%

The probability of getting at least 1 blue marble in the given situation is 0.375, i.e., 37.5%.

Probability is the ratio of favorable outcomes to the total number of outcomes.

It is given that there are 3 blue and 5 red marbles in the bag.

Therefore, the total number of marbles in the bag is 8.

Let's take two scenarios, one when one blue marble and one red marble are drawn and the second one when both marbles drawn are blue.

Let B and R be the events of drawing a blue marble and red marble, respectively.

Case 1:

The probability of getting one blue and one red marble is calculated as follows:

[tex]P(B =1, R=1) = \dfrac{3}{8}\times\dfrac{5}{7}[/tex]

                          [tex]= \dfrac{15}{56}[/tex]

Note that the replacement is prohibited.

Case 2:

The probability of getting two blue marbles is calculated as follows:

[tex]P(B =2) = \dfrac{3}{8}\times\dfrac{2}{7}[/tex]

               [tex]= \dfrac{6}{56}[/tex]

The probability of getting at least 1 blue marble is given as follows:

[tex]P(B\ge1) = P(B =1, R=1) + P(B =2)[/tex]

               [tex]= \dfrac{15}{56}+ \dfrac{6}{56}\\= \dfrac{21}{56}\\=\dfrac{3}{8}\\= 0.375[/tex]

Therefore, the probability of getting at least a blue marble is 0.375.

First off, let's make a table for y = sin(x)

(x , y): (0 , 0) (π/2 , 1) (π , 0) (3π/2 , -1) (2π , 0)

Now, making our table for y = 4sin(x) is simple. We just have to multiply all the y-values from the previous table by 4.

(x , y): (0 , 0) (π/2 , 4) (π , 0) (3π/2 , -4) (2π , 0)

Plotting these coordinates, we get the graph depicted in letter B.

a. -1.60377

b. 0.25451

c. 0.344

d. Option b) 78th

Step-by-step explanation:

The number of pieces in a regular bag of Skittles is approximately normally distributed with a mean of 38.4 and a standard deviation of 2.12.

a)What is the z-score value of a randomly selected bag of Skittles that has 35 Skittles? a) 1.62 b) -1.62 c) 3.40 d) -3.40 e)1.303.

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

z = 35 - 38.4/2.12

= -1.60377

Option b) -1.62 is correct

b) What is the probability that a randomly selected bag of Skittles has at least 37 Skittles? a) .152 b) .247 c) .253 d).747e).7534. .

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

z = (37 - 38.4)/2.12

= -0.66038

P-value from Z-Table:

P(x<37) = 0.25451

The probability that a randomly selected bag of Skittles has at least 37 Skittles is 0.25451

Option c) .253 is.correct

c) What is the probability that a randomly selected bag of Skittles has between 39 and 42 Skittles? a) .112 b) .232 c) .344 d).457 e).6125.

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

For 39 Skittles

z = (39 - 38.4)/2.12

= 0.28302

Probability value from Z-Table:

P(x = 39) = 0.61142

For 42 Skittles

z = (42 - 38.4)/2.12

= 1.69811

Probability value from Z-Table:

P(x = 42) = 0.95526

The probability that a randomly selected bag of Skittles has between 39 and 42 Skittles is:

P(x = 42) - P(x = 39

0.95526 - 0.61142

0.34384

= 0.344

Option c is.correct

d) What is the percentile rank of a randomly selected bag of Skittles that has 40 Skittles in it? a)82nd b) 78th c) 75th d)25th e)22nd

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

z = (40 - 38.4)/2.12

= 0.75472

P-value from Z-Table:

P(x = 40) = 0.77479

Converting to percentage = 0.77479× 100

= 77. 479%

≈ 77.5

Percentile rank = 78th

One way is to work backwards and check the factored form (x+6)(x-6) using the FOIL method.

Multiply the first terms, then outside terms, then inside terms, then last terms. Simplify and you will find the extended version of (x+6)(x-6) to be x^2-36, NOT the expression x^2-12x+36.

Answer:

D

Step-by-step explanation:

We simply put each of the points to test

For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate

So let’s proceed

(-3,8)

8 = -5(-3) - 7

8 = 15 -7

8 = 8

(-2,3)

3 = -5(-2) - 7

3 = 10 -7

3 = 3

(-1,-2)

-2 = -5(-1) - 7

-2 = 5-7

-2 = -2

(0,-7)

y = -5x -7

y = -5(0) - 7

y = 0-7 = -7

(1,-12)

y = -5(1) -7

-12 = -5 -7

-12 = -12

(2,-17)

-17 = -5(2) -7

-17 = -10-7

-17 = -17

We can see that all the listed points are on the given line

Although all these points lie on the line, we cannot say they represent the set of all solutions

The set of all solutions can simply be represented by the line of the equation

The value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

The inequality is given as

9.53 < √a < 9.54

On squaring both sides, we have

  9.54² > a > 9.53²

91.0116 > a > 90.8209

Thus, the value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.

The turtle walks away from the rock at a constant rate.

Step-by-step explanation:

A proportional relationship is one in which the two variables vary directly with each other and can be represented by the equation:

y = kx, where k is the constant of proportionality.

Also, a proportional relationship has a constant rate which is the ratio of the two variables.

A) The equation y = 3x is a proportional relationship because it is in the form y = kx, k =3

B) After 4 minutes, the turtle has walked 12 feet away from the rock.

We cant say that this is a proportional relationship because it may or may not be proportional.

C) The turtle walks for a bit, then stops for a minute before walking again.

It is not proportional

D) The turtle walks away from the rock at a constant rate

This is a proportional relationship because it has a constant rate
