Relative frequency of students who use online class in percentage = 62.17%
What is percentage?
Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.
For example 2% means [tex]\frac{2}{100}[/tex]. Here 2 is expressed as a fraction of 100.
Here,
Number of students using mobile in traditional class = 46
Total number of students in traditional class = 74
Relative frequency of students who use online class in percentage =
[tex]\frac{46}{74} \times 100[/tex]

The angle is a straight angle. It measures exactly 180 degrees.
What is the equation in slope -intercept form , of the line that is parallel to the guven line and passes through the point (0, 12
Answer:
A. y=-5+12
Step-by-step explanation:
It asks for slope intercept form which is y=mx+b. This matches the first option but not the last.
First you can rewrite the given equation (10x+2y=-2) in slope intercept form. That will give you y=-5x=1. (in the slope intercept form the number in front of the X is ur slope and the last number is ur Y intercept).
The question says that ur line is parallel to the given equation line. This means that they have the same slope. In your rewritten equation, y=-5x=1, the slope is -5 because it is in front of the X. A is the only option with -5 in the slope position.
All options are eliminated now but in case u want to know, when it tells you that the line passes through (0,12) that means the X intercept is 12. Because 0 is the x axis, and 12 is the Y. Y intercept just means the point where your line touches the Y axis.
Y intercept goes at the end and that also matches your first equation.

Given that 1+i is a root of the equation
x³ + 2x² + λx + μ = 0,
(a) find the values of the real constants λ and μ,
(b) find all the other roots of the equation.
[10]
(a) The values of the real constants λ and μ are -6 and 8, respectively.
(b) The roots of the equation are (1 + i), (1 - i), and -4.
We are given an equation. The equation is cubic in nature. It means the equation has three roots. The equation is given below.
x³ + 2x² + λx + μ = 0
One of the roots of the equation is given to us. The known root is "1 + i". The given root is a complex root. We know that complex roots occur in conjugate pairs. So, another root of the equation is "1 - i". Let the third root be represented by the variable "a". We can form the factors as given below.
[x - (1 + i)][x - (1 - i)](x - a) = 0
[x² - x(1 - i) - x(1 + i) + (1 + i)(1 - i)](x - a) = 0
[x² - x + ix - x - ix + (1² - i²)](x - a) = 0
[x² - 2x + (1 + 1)](x - a) = 0
(x² - 2x + 2)(x - a) = 0
x³ - ax² - 2x² + 2ax + 2x - 2a = 0
x³ - (a + 2)x² + (2a + 2)x - 2a = 0
This equation must be the same as the given equation. Now we will compare the coefficients of different powers of "x".
First, we compare the coefficient of x².
2 = -(a + 2)
a + 2 = -2
a = -4
Now, we compare the coefficient of x.
λ = 2a + 2
λ = 2*(-4) + 2
λ = -8 + 2
λ = -6
Now we compare the constant terms.
μ = -2a
μ = -2*(-4)
μ = 8

What is the equation for g(x) in simplest form?
g(x) = ____
g (x) = 4x² + 10 is the equation for g(x) in the simplest form.
What is a function?A special relationship where each input has a single output is called a function.
Given that, f(x) = 4x² + 6, the quadratic function g(x) is f(x) translated 3 units up.
The translation of a function f (x) in the Cartesian coordinate domain can be done by following the given guidelines:
Translation guidelines ;
Horizontal shifts
Right : f (x) → f (x - a)
Left : f (x) → f (x + a)
Vertical shifts
Up : f (x) → f (x) + b
Down : f (x) → f (x) - b
General shift (Horizontal and Vertical shift) is;
f (x) → f (x ± a) ± b
We will use the guidelines for Vertical shifts, where in this case the magnitude of b = 4.
f (x) = 4x² + 6
g (x) = f (x) + 4
g (x) = 4x² + 6 + 4
g (x) = 4x² + 10
Hence, the equation for g(x) in the simplest form is g (x) = 4x² + 10

Answer:1.7
Step-by-step explanation:
One Decimal Place Rule #1: If the last digit in 1.74 is less than 5, then remove the last digit.
One Decimal Place Rule #2: If the last digit in 1.74 is 5 or more and the second to the last digit in 1.74 is less than 9, then remove the last digit and add 1 to the second to the last digit.
One Decimal Place Rule #3: If the last digit in 1.74 is 5 or more and the second to the last digit in 1.74 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.When rounding 1.74 to one decimal place we use
One Decimal Place Rule #1. Therefore, the answer to "What is 1.74 rounded to 1 decimal place?" is:
The estimated answers by rounding each number to a 1 decimal place and then adding them together are 14.3, 35.9, 30.6, respectively.
Here are the estimated answers to the following calculations:
12.55 and 1.74 rounded to 1 decimal place are 12.6 and 1.7. The sum is 14.3.
30.38 and 5.49 rounded to 1 decimal place are 30.4 and 5.5. The sum is 35.9.
19.16 and 11.42 rounded to 1 decimal place are 19.2 and 11.4. The sum is 30.6.
The sum of all three calculations is 14.3 + 35.9 + 30.6 = 80.8.
To estimate the answers, we simply rounded each number to 1 decimal place. This means that we lost some precision, but the overall accuracy of the estimates is still good. For example, the actual sum of 12.55 and 1.74 is 14.29, which is very close to our estimate of 14.3.

Answer:
30 is the missing number.
Step-by-step explanation:
The equation is,
→ 2³ × x × 5 = 120
Then the value of x will be,
→ 2³ × x × 5 = 120
→ 8 × x × 5 = 120

The denominator of a fraction is three more than the numerator
Let it be x the numerator. Then we have:
• x + 3: Denominator.
,• x + 9: Numerator increased by nine.
,• (x + 3) + 9: Denominator increased by nine.
Since the simplified result of the fraction is 13/14, we can write and solve for x the following equation.
[tex]\begin{gathered} \frac{x+9}{(x+3)+9}=\frac{13}{14} \\ \frac{x+9}{x+3+9}=\frac{13}{14} \\ \frac{x+9}{x+12}=\frac{13}{14} \\ \text{ Apply cross product} \\ (x+9)\cdot14=13\cdot(x+12) \\ \text{ Apply distributive property} \\ 14\cdot x+9\cdot14=13\cdot x+13\cdot12 \\ 14x+126=13x+156 \\ \text{ Subtract 126 from both sides } \\ 14x=13x+156-126 \\ 14x=13x+30 \\ \text{ Subtract 13x from both sides} \\ 14x-13x=13x+30-13x \\ x=30 \end{gathered}[/tex]Now, we replace the value of x into the left expression from the equation we just solved.
[tex]\begin{gathered} \text{ Original fraction }=\frac{x+9}{(x+3)+9} \\ \text{ Original fraction }=\frac{30+9}{30+3+9} \\ \text{ Original fraction }=\frac{39}{42} \end{gathered}[/tex]Therefore, the original fraction is 39/42.
