Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 12 ( add 4x to both sides )
3y = 4x + 12 ( divide the terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex] and y- intercept c = 4
---------------------------------------------------
Given
- 5x + 3y = - 9 ( add 5x to both sides )
3y = 5x - 9 ( divide the terms by 3 )
y = [tex]\frac{5}{3}[/tex] x - 3 ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 3

A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah
Answer:
D
As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.
Step-by-step explanation:
The property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
Number of samples = 40
30% of them have period 4 lunch.
Total population = 380
25% of them have period 4 lunch.
Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.
We collect parameters from the population and statistics from the sample.
Thus, the property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

The set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant
is a A. Hyperbola.
What is a hyperbola?A hyperbola is symmetric along its conjugate axis and resembles the ellipse in many ways.
Examples of the hyperbola that are frequently seen include the path taken by the tip of a sundial's shadow, the scattering trajectory of subatomic particles, etc.
We all know the pictorial representation of a circle, ellipse, parabola, and hyperbola.
A hyperbola is subject to concepts like foci, directrix, latus rectus, and eccentricity.
The given diagram and statements represent a hyperbola.

The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. What is the average distance from venus to mars?
Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:
[tex] d_{t} = d_{1} + d_{2} [/tex]
First, we need to equal the base power 10 so we can sum both distances:
[tex]2.25 \cdot 10^{8} = 2.25 \cdot 10^{7} \times 10 = 22.5 \cdot 10^{7} km[/tex]
Now, average distance:
[tex]d_{t} = 2.5 \cdot 10^{7} + 22.5 \cdot 10^{7} = (2.5 + 22.5) \cdot 10^{7} = 25 \cdot 10^{7} km = 2.5 \cdot 10^{8} km[/tex]
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

Would someone please help me? Ravi decides to eliminate just 100 calories per day from his diet. He knows that each pound of body fat equals 3500 calories. How long will it take for Ravi to lose 10 pounds?
Answer:
350 days
Step-by-step explanation:
If Ravi is eliminating 100 calories per day, and one pound of body fat is 3500 calories, then it will take him 35 days to lose one pound of body fat.
Multiply 35 by 10 to find how long it will take for him to lose 10 pounds:
35(10)
= 350
So, it will take him 350 days to lose 10 pounds.
Answer:

Answer:
30 m
Step-by-step explanation:
Picture the question as a triangle
The length of the string is the hypotenuse, 60 m
The angle from the ground is 30
The right angle C is from the height of the kite to the ground
The missing angle A 60 is located on the top of the kite
now find b, the height
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(A)=adj/hyp
cos(A)=b/c
b=c*cos(A)
b=60*cos(60)
b=30

Answer: I just did the test so the answer is A. 5.8 units

The correct option is A.
What is length of line segment?The distance between any two points is the length of the line segment joining the points.
The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)
D = √((x2 – x1)² + (y2 – y1)²)
This is called the Distance Formula.
Given,
Coordinates of points Q (8, 2) and R (5, 7)
Length of QR = Distance between point Q and point R.
D = √((x2 – x1)² + (y2 – y1)²)
D = √((5 - 8)² + (7 - 2)²)
D = √(-3² + 5²)
D = √9 + 25
D = √34
D = 5.83 units
Length of QR rounded to one decimal = 5.8 unit
Hence, 5.8 unit is closest to the length of QR = 5.83units
