The number of students in the class after the changes here are 35.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

The question tells us that 7 more juniors have joined this class, while 2 seniors have dropped the class. Then the ratio would be 5 : 2 from the question.

This would give us the ratios as

From here we would have to cross multiply

2(3x + 7) = 5(2x - 2)

6x + 14 = 10x - 10

6x - 10x = -10 - 14

- 4x = -24

x = 6

Put the value of x in both equations

3x + 7 = 3 x 6 + 7

= 25

2x - 2 = 2 x 6 - 2 = 10

The magnitude of earthquake on seismograph will be 3 .

What is seismograph?

A seismograph is a device that measures and records crucial data concerning earthquakes. Electromagnetic sensors in seismographs convert ground vibrations into electrical voltages. Seismograms are records that a seismograph generates and displays .

Main Body:

formula given : M = ㏒₁₀T           where T =1000

substituting the value of T in the formula

M = ㏒₁₀ 1000

M = ㏒₁₀10³

M = 3㏒₁₀           (㏒₁₀Xᵃ = a㏒₁₀)

M = 3                  (㏒₁₀10 =1)

Therefore the magnitude of the earthquake is 3.

Step-by-step explanation:

to create a vertical asymptote (a tangent of the curve in infinity) at x = n we define e.g.

f(x) = 1/(x - n)

the cost x gets to n, the much closer the function gets to 1/0 and infinity.

so, the part to get us the asymptote at x = -4 is

1/(x + 4)

the part to get us the asymptote at x = 2 is

1/(x - 2)

and the part that gives us a zero solution at x = 3 is

(x - 3)

because that is what the point (3, 0) is : when x = 3. then y = 0.

now we only need to multiply all 3 parts to combine them :

f(x) = 1/(x + 4) × 1/(x - 2) × (x - 3)

A sample should be 47 to be taken if the desired margin of error is two minutes at a 95% level of confidence

Given information:

A medical facility wants to determine the average amount of time each patient spends with a staff member while creating patient appointment schedules. utilize a planned value of seven minutes for the population's standard deviation.

б=7, ME=2

95% Confidence (to the nearest whole number):

For 95% confidence interval z-critical value is z_{c}=1.96. So

n = (z * б /ME )² = (1.96* 7/ 2)= 47.05

The Requried sample size is 47

If the acceptable margin of error is two minutes at a 95% level of confidence, then a sample of 47 should be taken.

We need to simplify the above expression and will find the value of a.

[tex]a+\frac{4}{a}=4[/tex]

⇒ [tex]\frac{a^2+4}{a}=4[/tex]

⇒ [tex]a^{2}+4=4a[/tex]

The number of books each boy had based on the 3:1 ratio of the books remaining is 34 books

A ratio is a quantitative expression of the relationship between two values that indicates the relative proportion of each amount.

The initial number of books Ben had = The initial number of books Charlie has

The number of books Ben gave away = 16 books

The number of books Charlie gave away = 28 books

The ratio of the number of books Ben and Charlie had left is 3:1

Let x represent the number of books each of them initially have. Representing the numbers as a ratio gives;

The number of books Ben had left = x - 16

The number of books Charlie had left = x - 28

[tex]\dfrac{x - 16}{(x - 16) + (x - 28)} = \dfrac{3}{3+1}[/tex]

Equations representing the total costs for plan A and B are A = 19 + 0.50x and B = 13 + 1.5x, respectively, where x is the number of movies watches.

Cost of both the plans will be equal for 6 movies.

A linear function is defined as a function that has either one or two variables without exponents.

Given that, Wyatt is deciding between two different film streaming sites to subscribe to, plan A costs $19 per month plus $0.50 per film watched, plan B costs $13 per month plus $1.50 per film watched.

According to question,

A = 19 + 0.50x and

B = 13 + 1.5x

For costs being equal, we have,

A = B

19 + 0.50x = 13 + 1.5x

x = 6

Hence, for 6 films the costs of both the plans will be equal and equation for both the plans are A = 19 + 0.50x and B = 13 + 1.5x
