Find the value of each variable​

The arrangement in order of increasing radius is F⁻ < O²⁻ < Ne < Br⁻  < Rb

This is the distance between the outermost electron and the nucleus

This is the arrangement of electrons around the nucleus

This is the radius of an atom forming ionic bond

So, we have the electronic configurations of the corresponding ions in increasing order of ionic radius

F⁻ - 2, 8, < O²⁻ - 2, 8 < Ne - 2, 8 < Br⁻ - 2, 8, 18, 8 < Rb - 2, 8, 18, 8, 1

So, the arrangement in order of increasing radius is F⁻ < O²⁻ < Ne < Br⁻  < Rb

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

Percentage of dinner out = 65% - 40% = 25%

For 200 total tickets:

Number of dinning out raffle = 25% of 200 = 0.25 * 200 = 50 ticket

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.

Answer:

a)

Step-by-step explanation:

[tex]\dfrac{3p-1}{p^2-1}[/tex]

Factorize the denominator:

[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}[/tex]

Therefore,

[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}=\dfrac{A}{p+1}+\dfrac{B}{p-1}[/tex]

[tex]\implies 3p-1=A(p-1)}+B(p+1)[/tex]

When p = 1:

[tex]\implies 2=A(0)}+B(2)[/tex]

[tex]\implies B=1[/tex]

When p = -1:

[tex]\implies -4=A(-2)}+B(0)[/tex]

[tex]\implies A=2[/tex]

Therefore,

[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}=\dfrac{2}{p+1}+\dfrac{1}{p-1}[/tex]

Step-by-step explanation:

Relative Frequency =  [tex]\frac{Frequency*100}{Total Frequency}[/tex]

Frequency for the class with lower class is 23 =7

Total Frequency= 7+7+7+9+9+9+2=50

Relative Frequency =  [tex]\frac{7*100}{50}[/tex] = 14

The relative frequency for lower class limit 23 is 14

Answer:

582.76 square inches of glass is required to construct the tank.

Step-by-step explanation:

Base dimension = 22×12 inches

volume of fish tank =3960 cubic inches

volume= l×b×h

3960=22×12×h

h=3960/(22×12)

h=3960/462

h=8.57 inches

the glass used=lateral surface area of a rectangular prism

=2h(l+b)

=2×8.57(22+12)

=17.14(34)

=572.76square inches

Using the combination formula, it is found that 84 different groups of 6 people are possible from the 9 remaining friends.

The order in which the friends are chosen is not important, hence the combination formula is used to solve this question.

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

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

In this problem, 6 friends are chosen from a set of 9, hence:

[tex]C_{9,6} = \frac{9!}{6!3!} = 84[/tex]

84 different groups of 6 people are possible from the 9 remaining friends.

Answer:  that equivalent to the expression 2x+3x+8-3x-2 would be the choices A and C. If you notice, in choice A, you have just combined all the like terms which results in 2x+6 and in Choice C, you have combined all your constants and the the two terms 2x and 3x resulting in 5x-3x+6 which all remain equivalent to he original given expression

Step-by-step explanation:

Given -
