A slow 24-hour clock loses 25 minutes a day. At noon on the first of October, it is set to show the correct time. When will this clock next show the correct time?
Answer:
Nov 27 at 14:24 hours
Step-by-step explanation:
First let's figure out exactly when the slow clock will synchronize with a correct clockAt the rate of loss of 25 minutes per day, let x be the number of days when the two clocks coincideThe total time lost in x days = 25x minutesThe clocks will synchronize when the total time lost is exactly 24 hours.57.6 days equates to 57 days, 14 hours, 24 minutes (using a calculator)
Adding to Oct 1 at 12:00:00 we get this as Nov 27 at 14:24 hours

cutting out the circle, what was the area of the piece of paper that was left after she
cut out the circle? Use 3.14 form.
The area of the piece of paper left after cutting out the circle is 29.76 in².
Area of a figure:
The amount of unit squares that completely encircle the surface of a closed figure is its area. Area is measured in square units like cm² and m². A shape's area is a two-dimensional measurement. The term “area” refers to the space inside the boundary or perimeter of a closed shape.
You need to first determine the rectangle's area.
8x10=80 in²
determine the circle's overall area.
The diameter is 8 in so you would use 4 as the radius
A=πr²
A=3.14x4²
A=3.14x16
A=50.24 in²
The area of the circle must then be subtracted from the area of the rectangle.
80-50.24=29.76
The area of the piece of paper is 29.76 in ².

do you think this model satisfies assumptions for multiple regression? list 4 of the assumptions and next to each one tell why you do or do not think it is valid.
In multiple regression, we have 4 assumptions listed and explained below. They are valid.
Following are assumptions for multiple regression model:
1. Linear connection: Each predictor variable and the responder variable have a linear relationship.
Making a scatter plot of each predictor variable and the response variable is the simplest technique to check if this premise is true.
2. Lack of Multicollinearity: There is no significant correlation between any of the predictor variables.
Calculating the VIF value for each predictor variable is the quickest approach to see if this premise is true.
3. Independence: Each observation has its own validity.
The Durbin-Watson test, a formal statistical test that informs us whether or not the residuals (and consequently the observations) exhibit autocorrelation, is the easiest approach to find out if this assumption is true.
4. Homoscedasticity: At every point in the linear model, the residuals' variance is constant.
The simplest technique to check if this premise is true is to plot the standardized residuals against the expected values.

What is a Hexagon?A hexagon, also known as a sexagon, is a six-sided polygon that forms the shape of a cube in geometry. Any basic hexagon has a total internal angle of 720°.
In a regular hexagon, all sides are equal
Which means:
AB= BC
5p + q -5p = 6p-5p
q = p
So, every side of the hexagon is p = q
Which means that AB = BC = CD = DE = EF = FA = p =q
Recall that at the center, each side forms an angle
There are six sides in a hexagon.
Total angle = 360°
6x= 360°
x= 60°.
By the symmetry of regular hexagon, OA = OB
<OAB = <OBA
<AOB = x = 60°
Sum of all angles in a triangle is 180°
We add the values
<OAB = 60°.
<OAB is an equilateral triangle, thus every side is equal
Hence,
a. OA = Q = Q
b. OB = P =Q
c. EB = 2P =2Q.

Find each exact value if 0
Sin (x - y) if cos x = 8/17 and cos y = 3/5
Work Shown:
If cos(x) = 8/17, then sin(x) = 15/17. Use the identity [tex]\sin^2(\text{x}) + \cos^2(\text{x}) = 1[/tex] to determine this.
If cos(y) = 3/5, then sin(y) = 4/5 using that same identity.
So,
sin(x-y) = sin(x)cos(y) - cos(x)sin(y)
sin(x-y) = (15/17)*(3/5) - (8/17)*(4/5)
sin(x-y) = 45/85 - 32/85
sin(x-y) = (45 - 32)/85
sin(x-y) = 13/85

Area of ABCD=40cm^2
Work out the values of f and g.
You must show all your working
The values for g and f for the length of sides of the trapezium are 8 and 6 respectively.
How to evaluate for the values of g and f for the trapeziumGiven the area of trapezium = 60 cm², then:
1/2 × (g + 4g) × f = 60 cm²
by simplification
f(g + 2) = 60 cm²...(1)
for the area of ABCD = 48 cm², then:
f × g = 48 cm²
f = 48/g...(2)
put 48/g for f in equation (1) to get g;
48/g(g + 2) = 60
60g = 48g + 96 {cross multiplication}
60g - 48g = 96 {collect like terms}
12g = 96
g = 96/11 {divide through by 11}
g = 8
put 8 for g in equation (2) to get f;
f = 48/8
f = 6.
Therefore, the values for g and f for the length of sides of the trapezium are 8 and 6 respectively.

The provided parallelogram has angles of 45 degrees and 45 degrees, as well as 48 degrees and 48 degrees.
What is parallelogram?A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure. A parallelogram is a quadrilateral with opposing sides that are parallel and equal. It has equal interior opposite angles. In addition, the angles on the same side of the transversal add up to 180 degrees or are additive to each other.
Here,
A parallelogram has two pairs of opposite angles that are equal.
Since one angle of the parallelogram is 48 degrees, its opposite angle must also be 48 degrees.
The other two angles must add up to 90 degrees (since they form a right angle), so they must each be equal to 180 - 90 = 90 degrees / 2 = 45 degrees.
