What is a scale factor?In Geometry and Mathematics, a scale factor simply refers to the ratio of two corresponding side lengths in two similar geometric figures such as pentagons, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.
In Geometry, the scale factor of the dimensions of a geometric figure can be calculated by using the following formula:
(Scale factor of dimensions)² = Scale factor of area
(Scale factor of dimensions)² = 25
Scale factor of dimensions = √25 = 5

Answer:
a) 11.283 dollars
b) 1.435 hour
Step-by-step explanation:
1 kilo watt of electricity used for 1 hour
Charges of electricity per unit = $0.05224
Laura uses 5 heaters to warm her house. The electricity consumed by each use 1800 wats or 1.8 kilo wats
a) Charges in one day = 5 heaters * 1.8 kilo wats per hour * 24 hour* $0.05224 per kilowats per hour
= 11.283 dollars
b) 75 wat light bulb consumes 0.075 kilo wats per hour
Charge per kilowat per hour = $0.05224
In order to cost 1 $, the 75 wat bulb need to be on for 1.435 hour

A) Create a confidence interval for the percentage of people to company contracts

Answers
Create a 90% confidence interval for the percentage of people the company contacts who may buy something.
Answer:
CI = (8.84%, 11.92%)
We are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.
Step-by-step explanation:
We are given;
n = 1060
x = 110
Confidence level = 90%
Sample proportion; p^ = x/n = 110/1060
p^ = 0.1038
DF = n - 1 = 1060 - 1 = 1059
From the table attached, the critical value for a confidence level of 90% at a DF greater than 1000 is 1.645
Formula for CI is;
CI = p^ ± t√(p^(1 - p^)/n)
CI = 0.1038 ± 1.645√(0.1038(1 - 0.1038)/1060)
CI = 0.1038 ± 0.0154
CI = (0.0884, 0.1192) or
CI = (8.84%, 11.92%)
Thus, we are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.

Answer:
100%
Step-by-step explanation:
The percentage change can be computed from ...
pct change = ((new value)/(old value) -1) × 100%
= ((1/2)/(1/4) -1) × 100%
= (2 -1) × 100%
= 100%
The increase by 1/4 from 1/4 to 1/2 is an increase of 100%.

A racing car driver is investigating whether the type of fuel he uses in his car affects his overall speed. He uses three different types of fuel. The driver runs an experiment where he fills his car with each type of fuel 20 times, and each time records the time taken to drive one lap of a track. A one-way ANOVA test is conducted to test the null hypothesis that type of fuel is not a significant factor in determining speed. The result of the test is that the null hypothesis is not rejected.
The conclusion that follows from this test is that: __________
a. it has been proven that the type of fuel is a significant factor in determining speed
b. it cannot be ruled out that the type of fuel is an insignificant factor in determining speed
c. it has been proven that the type of fuel is an insignificant factor in determining speed
d. it has been proven that the type of fuel can sometimes be a significant factor in determining speed
Answers
Answer:
b. it cannot be ruled out that the type of fuel is an insignificant factor in determining speed.
Step-by-step explanation:
From the question :
Let the speed of each fuel be represented as ;
u1, u2, u3
The null hypothesis, H0 ;
H0 : u1 = u2 = u3
H0 is of the notion that fuel type is not a significant factor in determining speed
The alternative hypothesis, H1;
H1 : u1 ≠ u2 ≠ u3
The alternative is the opposite of the null, fuel type is a significant factor in determining speed
If after conducting the statistical test, the null hypothesis cannot be rejected ;
Then the conclusion will be ;
There is no significant evidence to conclude that the fuel type is a significant factor in determining speed ;
Hence, fuel fuel type remains an insignificant factor in determining speed.

The functions f(x) = x^2 – 3 and g(x) = –x^2 + 2 are shown on the graph.
The graph shows f of x equals x squared minus 3, which is an upward-opening parabola with a vertex at 0 commas negative 3 and a point at negative 1 comma negative 2, and a point at 1 comma negative 2. The graph also shows g of x, which is a downward opening parabola with a vertex at 0 commas 2 and a point at negative 1 comma 1, and a point at 1 comma 1.
Explain how to modify the graphs of f(x) and g(x) to graph the solution set to the following system of inequalities. How can the solution set be identified?
y ≤ x^2 – 3
y > –x^2 + 2
Answers
The solution set to the given system of inequalities is represented by the shaded region under the curve of f(x) = x^2 – 3 (including the points on the curve) and above the curve of g(x) = –x^2 + 2 (excluding the points on the curve). The overlapping region between these shaded areas represents the solution set to the system.
To graph the solution set to the system of inequalities y ≤ x^2 – 3 and y > –x^2 + 2, we can modify the graphs of f(x) = x^2 – 3 and g(x) = –x^2 + 2 accordingly. Here's how:
For the inequality y ≤ x^2 – 3:
The original graph of f(x) = x^2 – 3 is an upward-opening parabola with a vertex at (0, -3).
To graph y ≤ x^2 – 3, we need to shade the region below or on the parabola. This includes all points on the parabola itself.
Therefore, we shade the area under the curve of the original graph of f(x) and include the points on the curve.
For the inequality y > –x^2 + 2:
The original graph of g(x) = –x^2 + 2 is a downward-opening parabola with a vertex at (0, 2).
To graph y > –x^2 + 2, we need to shade the region above the parabola. This excludes all points on the parabola itself.
Therefore, we shade the area above the curve of the original graph of g(x) but exclude the points on the curve.
By modifying the graphs of f(x) and g(x) according to these shading instructions, we can graphically represent the solution set to the system of inequalities.
The solution set can be identified by observing the overlapping region or the intersection between the shaded area under the curve of f(x) and the shaded area above the curve of g(x). The points within this overlapping region satisfy both inequalities simultaneously.

The length of a rectangular floor is 4 feet longer than its width w. The area of the floor is 525 ft^2. A) Write a quadratic equation in terms of w that represents the situation. B) What are the dimensions of the floor? Show your work.
Answers
Answer:
w² + 4w - 525 = 0
Width of rectangle = 21 feet
Length of rectangle = 25 feet
Step-by-step explanation:
Given:
Area of rectangular floor = 525 ft²
Find:
Equation
Dimensions of the floor
Computation:
Assume;
Width of rectangle = w feet
So,
Length of rectangle = w + 4 feet
Area of rectangular floor = length x width
Area of rectangular floor = w(w + 4)
525 = w² + 4w
w² + 4w - 525 = 0
w² + (25 - 21)w - 525 = 0
w² + 25w - 21w - 525 = 0
w(w + 25) -21(w + 25)
(w + 25)(w - 21)
So,
w = -25 , w = 21
So,
Width of rectangle = 21 feet
Length of rectangle = w + 4 feet
Length of rectangle = 21 + 4 feet
Length of rectangle = 25 feet

You need to find x. In order to do this you can use that butterfly method/cross multiplication. You do 4 times set equal to 18*16.
Next, you get 18*16=288 and you must divide the other side (4x) to get your final answer. So, 288/4= 72 minutes.
