How many atoms of element X with one valence electron will combine with one oxygen atom?
A.) 2
B.) 1
C.) 3
D.) 5

Answer:  1/16

In decimal form, this is equivalent to 0.0625

=====================================================

Explanation:

Each of the four sections are of equal area, so that means the probability of landing on any given color is 1/4.

The probability of landing on green first is 1/4, then followed by red is another 1/4. We multiply these fractions. This is valid because each event of spinning the spinner is independent of one another. None of the spins affect any others.

We then get (1/4)*(1/4) = (1*1)/(4*4) = 1/16

The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required event / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Assuming that each section of the spinner has an equal chance of being landed on, the probability of landing on the green on the first spin is 1/4.

Since each spin is independent of the others, the probability of landing on red on the second spin is also 1/4.

To find the probability of both events happening, we multiply the probabilities of each event:

P(green and red) = P(green) × P(red) = 1/4 × 1/4 = 1/16

Therefore,

The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.

[tex]-27x^2\\[/tex]

Step-by-step explanation:

(Assuming you can use a calculator)

[tex]\sqrt[3]{-729x^6} = \sqrt[3]{-1} * \sqrt[3]{729} * \sqrt[3]{x^6} \\\sqrt[3]{-1} =-1\\\sqrt[3]{729} = 27\\\sqrt[3]{x^6} = ((x^6)^{1/3}) = x^(6/3) = x^2\\\\hence\\\sqrt[3]{-729x^6} = -1*27*x^2 = -27x^2[/tex]

Answer:

It’s true

Step-by-step explanation:

Proof by induction

Let the four chosen numbers be x_1, … x_4 and, without loss of generality, let x_1 < x_2, … < x_4.

For x_1 = 1, the smallest possible choice, let x_2 = x_1 + 20 = 21 be the smallest possible choice that has a difference larger than 19. Likewise, x_3 = x_2 + 20 = x_1 + 40 = 41. Then x_4 has to be at least x_3 + 20 = x_1 + 60 = 61 which is out of range.

For the induction, suppose that x_4(n) = x_1(n) + 60 > 60 and therefore x_4(n) can’t be chosen for a given x_1(n). Then incrementing x_1(n+1) = x_1(n) + 1 would require x_4(n+1) to be at least x_1(n) + 1 + 60 = x_4(n) + 1 > 61, so this is out of range as well.

For another induction, suppose that x_4(n) = x_2(n) + 40 > 60 and therefore x_4(n) can’t be chosen for a given x_2(n). Then incrementing x_2(n+1) = x_2(n) + 1 would require x_4(n+1) to be at least x_2(n+1) + 40 = x_4(n) + 1 > 61, so this is out of range as well.

Likewise, for the induction, suppose that x_4(n) = x_3(n) + 20 > 60 and therefore x_4(n) can’t be chosen for a given x_3(n). Then incrementing x_3(n+1) = x_3(n) + 1 would require x_4(n+1) to be at least x_3(n+1) + 20 = x_4(n) + 1 > 61, so this is out of range as well.

Therefore all choices of x_1, x_2, x_3 with differences greater than 19 leaves no choice of x_4 within range with x_4 > x_3 + 19.

Answer:The answer is =3,7

Step-by-step explanation:

Answer:

nth term = 10 + (n - 1)-3

Step-by-step explanation:

a) 10, 7, 4, 1

First term,a = 10

Common difference,d = 7 - 10 = -3

nth term = a + (n - 1)d

nth term = 10 + (n - 1)-3

b 6, 4, 2,0

First term,a = 6

Common difference,d = 4 - 6 = -2

nth term = a + (n - 1)d

nth term = 6 + (n - 1)-2

c) 9,4 -1,-6

First term,a = 9

Common difference,d = 4 - 9 = -5

nth term = a + (n - 1)d

nth term = 9 + (n - 1)-5

d) 2.5, 2. 1.5, 1

First term,a = 2.5

Common difference,d = 2 - 2.5 = -0.5

nth term = a + (n - 1)d

nth term = 2.5 + (n - 1)-0.5

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

The least 3 digit number divisible by 30 is 120 and the greatest is 990.

Answer: 30

Step-by-step explanation:

Divisible by 2,3 and 5 means divisible by 2*3*5=30

So we require to calculate number of multiples of 30 in the range 100 to 999.

The least 3 digit number divisible by 30 is 120 and greatest is 990.

This is an AP series with common difference 30.

First number is 120 and n'th number is 990.

We need to find n.

Using the AP series formula

120 + (n-1)*30= 990

or n= 30

There are 30 3-digit numbers divisible by 2,3 and 5.
