The north campus had 600 students and the south campus had 600 students.Using this ratio, we can solve for the total number of students at the north campus, which is 600 students (10 women x 60 = 600 students).
Before the merger, the north campus had 10% of the students as women, which is the same as saying 10 out of every 100 students were women. This means that 100 students would have been 10 women. Using this ratio, we can solve for the total number of students at the north campus, which is 600 students (10 women x 60 = 600 students). The same process can be done for the south campus, which had 50% of its students as women. This means that 50 out of every 100 students were women, which means that the total number of students at the south campus would have been 600 (50 women x 60 = 600 students). Therefore, the north and south campuses had 600 students each before the merger, for a total of 1200 students between the two campuses.

A. 39°
Step-by-step explanation:
Adjacent angles on a straight line is equal to 180°
Vertical opposite angles are equal to each other

The width of the rectangle is the length minus 5 units. The area of the rectangle is 6 square units. What is the width, in units, if the rectangle?
Answer:The width of the rectangle is 1 unit
Step-by-step explanation:Let the length of the rectangle be x
let the breadth be x-5
Since ,area of rectangle=length*breadth
area = x*(x-5)
6=x^2-5x
x^2-5x-6=0
solving the above equation,
x^2-(6x-x)-6=0
x^2-6x+x-6=0
x(x-6)+1(x-6)=0
(x-6)(x+1)=0
x=6 and x=-1
since the breadth cannot have negative value
Hence ,the breadth of rectangle is 1 unit

Answer:
Step-by-step explanation:
The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.
Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:
Regression 1: y = -5.8x - 6.5, r = -0.7621
Regression 2: y = 2.4x - 14.7, r = 0.809
Regression 3: y = -7.4x - 17.4, r = -0.233
Regression 4: y = -3.4x - 8.5, r = -0.6121
Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

Which of the given functions could this graph represent?
OA. f(t) = (x - 1)(x - 2)(x + 1)(x + 2)
O B. f(x) = x(x - 1)(1 + 1)
Oc. /(x) = x(x - 1)(x - 2)(x + 1)(x + 2)
OD. (r) = x(x - 1)(x - 2)
The correct answer is option C. f(x) = x(x - 1)(x - 2)(x + 1)(x + 2)
Explanation:
To determine the correct answer, we need to look at the zeros of the given functions and compare them to the zeros shown on the graph. The zeros of a function are the values of x that make the function equal to zero. These are also the points where the graph of the function crosses the x-axis.
Option A: f(t) = (x - 1)(x - 2)(x + 1)(x + 2)
The zeros of this function are x = 1, x = 2, x = -1, and x = -2.
Option B: f(x) = x(x - 1)(x + 1)
The zeros of this function are x = 0, x = 1, and x = -1.
Option C: f(x) = x(x - 1)(x - 2)(x + 1)(x + 2)
The zeros of this function are x = 0, x = 1, x = 2, x = -1, and x = -2.
Option D: f(r) = x(x - 1)(x - 2)
The zeros of this function are x = 0, x = 1, and x = 2.
Comparing the zeros of these functions to the zeros shown on the graph, we can see that option C is the correct answer. The graph shows zeros at x = 0, x = 1, x = 2, x = -1, and x = -2, which are the same zeros as the function f(x) = x(x - 1)(x - 2)(x + 1)(x + 2).

A geometric sequence has first term 14 and common ratio 2. Which term of the sequence is 64?
The required, fourth term of the geometric sequence is 64.
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
We can use the formula for the nth term of a geometric sequence to solve the problem. The nth term of a geometric sequence with first term a and common ratio r is given by:
[tex]an = ar^(n-1)[/tex]
In this case, the first term is 14 and the common ratio is 2. So the nth term is:
[tex]an = 14*2^{n-1}\\[/tex]
So
[tex]14(2^{n-1}) = 64\\2^{n-1} = 64/14 = 32/7[/tex]
To solve for n, we can take the logarithm of both sides of the equation. We can use any base for the logarithm, but it's usually convenient to use base 2 since the equation involves powers of 2. So
[tex]log_2(2^{n-1}) = log_2(32/7)\\(n-1) = log_2(32/7)\\n = log_2(32/7) + 1[/tex]
Using a calculator, we can approximate log_2(32/7) as 2.665. So:
n = 2.665 + 1
n ≈ 3.665
Since n must be a whole number (we're looking for a specific term of the sequence), we can round up to the nearest integer to get:
n = 4
Therefore, the fourth term of the sequence is 64.

How to find the scale factor of the preimage to the image?The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.
The scale factor of the preimage to the image can be found by finding the ratio of the corresponding sides of the preimage to the image. That is:
scale factor = DC / D'C'
scale factor = 5/2
Also, the scale factor = BC / B'C' and the scale factor is constant (i.e. 5/2)

what is 10 feet to meters?
10 feet to meters can be find out by simply dividing the 10 feet by 3.081 so the value will be 3.048 meters.
Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
One foot is equal to 0.3048 metres, or 3048/10000 metres. So, you multiply 10 by either 0.3048 or 3048/10000 to convert 10 feet to metres.
For the decimal answer, we use 0.3048, and for the fractional answer, we use 3048/10000. The math, formulas, and conversions from 10 feet to metres are shown below.

In this case, the area of the inner cylinder is 2π(e^8/2)ln 8 and the area of the outer cylinder is 2πln 8e^8. The volume is then equal to the integral of the area of the cylindrical

if the sum of the measures of the interior angles of a polygon is 1980°, how many sides does the polygon have?
Answer:
The polygon has 13 sides.
Step-by-step explanation:
The sum of the interior angles of a polygon is (n - 2) * 180, where n is the number of sides. This formula can be set equal to the sum of the interior angles to determine how many sides it has.
(n - 2) * 180 = 1980
180n - 360 = 1980
180n = 2340
n = 13
