A is probably the one that would represent most of the population since it has a bigger fraction.
And it would be around 410 seniors who would plan to go to a 4-year college.
We have to determine whether the following surveys probably would best represent the entire population of seniors.
What is the probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Therefore, A is probably the one that would represent most of the population since it has a bigger fraction.

An estimated 416 seniors plan to attend a 4-year college.
Now, For the number of seniors who plan to go to a 4-year college, we can use the proportion of seniors in the sample who plan to attend a 4-year college and apply it to the entire senior class.
From the sample in option a), 16 out of 25 seniors plan to attend a 4-year college.
To estimate the number of seniors who plan to attend a 4-year college, we can use the following proportion:
16/25 = x/650
Solving for x, we get:
x = (16/25) x 650
x = 416
Therefore, an estimated 416 seniors plan to attend a 4-year college.

The number of possible arrangements of pictures she can hang on her wall is 120.
How many possible arrangements of pictures can she hang?
The number of possible arrangements can be determined by dividing the factorial of 6 by the factorial of 3.
Number of possible arrangements = 6! / 3!
( 6 x 5 x 4 x 3 x 2 x 1) / (3 x 2 x 1) = 6 x 5 x 4 = 120

11(15g-13)=-6 help please
Answer:
g = 0.83
Step-by-step explanation:
11(15g-13) =-6
165g - 143 = -6
165g = 137
165 165
g = 0.83
The solution of the given equation 11(15g-13) = -6 is g = 0.83
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
11(15g-13) = -6
To solve the above equation following steps are taken,
Divide both the side of the equation by 11
11(15g-13)/11 = -6/11
Solving them we get,
15g - 13 = -6/11
Adding 13 both the sides,
15g - 13 + 13 = -6/11 + 13
So we obtain,
15g = -6/11 + 13
Solving the numbers right hand side,we get
15g = 137/11
Dividing both the sides by 15 we get,
g = 137/165
or, g = 0.83
Hence,The solution of the given equation 11(15g-13) = -6 is g = 0.83

Write an equation in slope-intercept form for the line described. Slope 9/2, passes through (0,-13/2)

We know that the slope is 9/2
[tex]y=\frac{9}{2}[/tex]
[tex]y=\frac{9}{2}x+b[/tex]
To solve for b, we can plug in the point given, since it's on the line.
[tex]-\frac{13}{2}=\frac{9}{2}(0)+b[/tex]

Given the graph, find the distance of GH. Round to the nearest tenth.
Answer:
GH = 6.3 units
Step-by-step explanation:
Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).
Distance between G and H = [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] G(-2, -3) = (x_1, y_1) [/tex]
[tex] H(0, 3) = (x_2, y_2) [/tex]
[tex] GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2} [/tex]
[tex] GH = \sqrt{(2)^2 + (6)^2} [/tex]
[tex] GH = \sqrt{4 + 36} = \sqrt{40} [/tex]
[tex] GH = 6.3 units [/tex] (nearest tenth)

What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
Your car can drive 300 miles on a tank of 15 gallons
300 miles → 15 gallons
Let x be the number of miles or distance a car travel in 40 gallons
x → 40 gallons
300/x = 15/40
x = (300×40)/15
x = 800 miles
Thus, the car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

Find the midpoint of the segment joining X(5,6) and Y(9,2).
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
[tex]M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})[/tex]
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
[tex]M=(\frac{5+9}{2},\frac{6+2}{2})[/tex]
Add:
[tex]M=(\frac{14}{2},\frac{8}{2})[/tex]
Divide by 2:
[tex]M=(7,4)[/tex]

Find the general solution of the following equation: y'(t) = 3y -5
Answer:
The general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
Step-by-step explanation:
Since the differential equation is given as y'(t) = 3y -5
The differential equation is re-written as
dy/dt = 3y - 5
separating the variables, we have
dy/(3y - 5) = dt
dy/(3y - 5) = dt
integrating both sides, we have
∫dy/(3y - 5) = ∫dt
∫3dy/[3(3y - 5)] = ∫dt
(1/3)∫3dy/(3y - 5) = ∫dt
(1/3)㏑(3y - 5) = t + C
㏑(3y - 5) = 3t + 3C
taking exponents of both sides, we have
exp[㏑(3y - 5)] = exp(3t + 3C)
3y - 5 = [tex]e^{3t}e^{3C}[/tex]
3y - 5 = [tex]Ae^{3t}[/tex] [tex]A = e^{3C}[/tex]
3y = [tex]Ae^{3t}[/tex] + 5
dividing through by 3, we have
y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
So, the general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
