Satyam and Shivam are playing a game. One of them codes a number and the other has to decode it. They use a part of the keyboard (shown below) for coding their messages. Using this coding system, Satyam asks Shivam to find out his phone number which he coded as symbols.
Which of the following is his phone number?
The coded message "&*()" corresponds to the phone number 6789. By matching the symbols with the corresponding keyboard numbers, Satyam's phone number can be decoded.
To decode the coded message and find out Satyam's phone number, we need to match the symbols in the coded message with their corresponding keyboard numbers.
Given the coding system provided, let's decode the coded message:
CODE&*() represents the symbols used in the coded message.
Comparing the symbols with the keyboard numbers, we have:
& corresponds to 6
* corresponds to 7
( corresponds to 8
) corresponds to 9
Therefore, the decoded message translates to the phone number: 6789.
In conclusion, Satyam's phone number, which was coded using the symbols &, *, (, and ), is 6789.
This decoding process involves a simple one-to-one mapping between the symbols and the corresponding keyboard numbers. By identifying the symbols in the coded message and matching them with the appropriate keyboard numbers, we can accurately determine Satyam's phone number.

Answer:
Candle burns down 1 cm per hour
I’m doing the assignment!
The correct statement that describes how the slope is related to the burning of a candle is "Candle burns down 1 cm per hour."
The correct option is D.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
The statement "The slope of the graph is -1" indicates that for each unit of increase in the horizontal variable (e.g. time), the vertical variable (e.g. height of the candle) decreases by 1 unit.
Therefore, the correct statement that describes how the slope is related to the burning of a candle is "Candle burns down 1 cm per hour."
Option A ("Candle height increases 1 cm per hour") and option C ("Candle is 1 cm tall") are not consistent with a negative slope.
Option B ("Candle height decreases 9 cm per hour") is not consistent with a slope of -1, as it implies a steeper slope.

4 friends share 3 pizzas equally how much pizza did each friend get?
Answer:
3/4
Step-by-step explanation:
No matter how many pizzas there are, if we divide each pizza to 4 slices, each one gets one slice from each pizza, that is 1/4 of a pizza for each brother. Since there are 3 pizzas, simply multiply 3 x 1/4 = 3/4
Answer:
It depends on the amount of slices
Step-by-step explanation:
It depends on the amount of slices
If there are 8 slices on each pizza, than it's 6 slices per friend. If it's 6, than its 4.5. I assume you mean with 8 slices, so it's 6 slices per friends

Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.
Through (15,3) and (3,15)
Answer:
y=-x+18
Step-by-step explanation:
Equation of a line
A line can be completely defined by two points. Suppose we know the line passes through points A(x1,y1) and B(x2,y2).
The equation for a line can be written as:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept. Both values can be determined by using the coordinates of the given points.
First, determine the slope with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are: A(15,3) B(3,15)
[tex]\displaystyle m=\frac{15-3}{3-15}=\frac{12}{-12}=-1[/tex]
The equation of the line can be written as:
[tex]y=-x+b[/tex]
Now, use any point to determine the value of b. Substitute (15,3):
[tex]3=-15+b[/tex]
Solve for b:
b=18
The equation of the line is
y=-x+18
The slope is -1 and the y-intercept is 18.

What is surface area of a sphere?A sphere is defined as the set of all points in three-dimensional Euclidean space that are located at a distance.
The area occupied by a three-dimensional object by its outer surface is called the surface area.
The surface area of a sphere is expressed as;
SA = 4πr²
where r is the radius and it's calculated as;
C = 2πr
9 = 2πr
r = 4.5/π =
SA = 4 π × (4.5/π)²

What is the graph of a function?The graph of a function shows the correlation between its inputs (represented by x-values) and matching outputs (represented by y-values). It is a means of illustrating the actions and traits of a function.
Plotting points that conform to the function's rule in a cartesian coordinate system results in the graph of the function. An input-output pair for the function is represented by each point on the graph. The point's x-coordinate represents the input value, while its y-coordinate represents the output value.
We can further use the graph to determine the range, domain, y-intercept, x-intercept and so many others from a graph.

According to the Census Bureau, 3.29 people reside in the typical American household. A sample of 16 households in Arizona retirement communities showed the mean number of residents per household was 2.76 residents. The standard deviation of this sample was 1.29 residents. At the 0.05 significance level, is it reasonable to conclude the mean number of residents in the retirement community household is less than 3.29 persons?
(a) State the null hypothesis and the alternate hypothesis. (Round your answer to 2 decimal places.)
H0: μ ≥

(Click to select)Fail to rejectReject H0. Mean number of residents (Click to select)is necessarilyis not necessarily less than 3.29 persons.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Alpha = 0.05
Sample size (n) = 16
Population mean(σ) = 3.29
Sample mean (m) = 2.76
Sample standard deviation (sd) = 1.29
(1)
Null hypothesis : μ ≥ 3.29
Alternative hypothesis : μ < 3.29
(2)
From the t distribution table :
The Null hypothesis should be rejected if
t < - t0
To obtain t0:
Degree of freedom (df) = n - 1 = 16 - 1 = 15 at alpha = 0.05
t0 = 1.753 ( left tailed) = - 1.753
(3)
Value of test statistic:
t = (m - σ) / (sd / √n)
(2.76 - 3.29) / (1.29 / √16)
-0.53 / 0.3225
t = - 1.643
Comparing t < - t0
But : -1.643 > - 1.753
Hence,
t > - t0
Hence, we fail to reject the null hypothesis
