The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters. What is the length and the width of the table?
Answer:
Length = 13.5 m
Width = 4.5 m.
Step-by-step explanation:
Use an equation in x, where x = width of the table.
Length = 3x, so:
2*3x + 2x = 36
6x + 2x = 36
8x = 36
x = 36/8 = 4.5 metres.
So the length = 3*4.5 = 13.5 and width = 4.5 m.
Length = 13.5 m
Width = 4.5 m.
What is the perimeter?A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter.
Given, The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters.
Use an equation in B, where B = width of the table.
Length = 3B,
2*3B + 2B = 36
6B + 2B = 36
8B = 36
B = 36/8 = 4.5 meters.
So the length = 3*4.5 = 13.5 and width = 4.5 m.
Therefore, the length and the width of the given rectangle are 4.5 and 13.5 respectively.

how do you tell if an equation is a function
Answer:
Step-by-step explanation: You can tell whether a relation is a function by plotting the numbers on a graph and applying the vertical line test. If no vertical line passing through the graph intersects it at more than one point, the relation is a function.

Answer:
The ratio is 7 : 13
Step-by-step explanation:
Given that:
Number of plain glazed donuts made on Saturday = 13

Hey
Step-by-step explanation:
Where is the question
Select the correct answer.
The branch manager of a clothing store is analyzing the average total bill of sale for his location. The national manager has communicated that
the overall population mean is $45.90 with a standard deviation of $10.3.1. The branch manager has a sample of 400 total bills of sale for his
location. By the central limit theorem, which interval can the branch manager be 95% certain that the sample mean will fall within?
Answer:
We can be 95% certain that the sample mean will fall within $44.87 and $46.93
Step-by-step explanation:
Empirical Rule:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Central Limit Theorem:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $45.90, standard deviation $10.31.
Sample:
By the Central limit theorem, mean $45.90, standard deviation [tex]s = \frac{10.31}{\sqrt{400}} = \frac{10.31}{20} = 0.5155[/tex]
Which interval can the branch manager be 95% certain that the sample mean will fall within?
By the Empirical Rule, within 2 standard deviations of the mean. So
45.90 - 2*0.5155 = $44.87
45.90 + 2*0.5155 = $46.93
We can be 95% certain that the sample mean will fall within $44.87 and $46.93
It is a collection or set of units or
entities from whom we got the data.
universe
variable
population
sample
Answer:
Population.
Step-by-step explanation:
Population can be defined as a collection or set of units or entities from whom we got the data.
This ultimately implies that, a population is the larger set from which other units can be picked from.
Hence, a population is an entire collection of outcomes or objects from which we can obtain or collect data. For example, the number of new born babies in a hospital, a country and the total number of football players in a soccer league.
Population = Movies.
Subset (sample) = comedy movies, horror movies, romance movies, and action movies.

w=x^2-2yx make y the subject of the formula
Answer:
[tex]y=\dfrac{x^2-w}{2x}[/tex]
Step-by-step explanation:
The given equation is :
w=x²-2yx
We need to find the value of y.
Subtract x² from both sides.
w-x²=x²-2yx-x²
w-x² = -2yx
Dividing both sides by -2x
[tex]\dfrac{w-x^2}{-2x}=\dfrac{-2yx}{-2x}\\\\y=\dfrac{w-x^2}{-2x}\\\\y=\dfrac{x^2-w}{2x}[/tex]
So, the value of y is equal to [tex]\dfrac{x^2-w}{2x}[/tex].

The function below has at least one rational zero. Use this fact to find ALL zeros of the function.
g(x)=5x^3+x^2-20^x-4
If there is more than one zero, separate them with commas. Write exact values, not decimal approximations.
Answer: 4 zeros
Step-by-step explanation:
If you want to use the Rational Zeros Theorem, as instructed, you need to use synthetic division to find zeros until you get a quadratic remainder.
P: ±1, ±2, ±3, ±6 (all prime factors of constant term)
Q: ±1, ±7 (all prime factors of the leading coefficient)
P/Q: ±1, ±2, ±3, ±6, ±1/7, ±2/7, ±3/7, ±6/7 (all possible values of P/Q)
Now, start testing your values of P/Q in your polynomial:
f(x)=7x4-9x3-41x2+13x+6
You can tell f(1) and f(-1) are not zeros since they're not = 0Now try f(2) and f(-2):
f(2)=7(16)-9(8)-41(4)+13(2)+6
112-72-164+26+6 ≠ 0
f(-2)=7(16)-9(-8)-41(4)+13(-2)+6
112+72-164-26+6 = 0 OK!! There is a zero at x=-2
This means (x+2) is a factor of the polynomial.
Now, do synthetic division to find the polynomial that results from
(7x4-9x3-41x2+13x+6)÷(x+2):
-2⊥ 7 -9 -41 13 6
-14 46 -10 -6
7 -23 5 3 0 The remainder is 0, as expected
The quotient is a polynomial of degree 3:
7x3-23x2+5x+3
Now, continue testing the P/Q values with this new polynomial. Try f(3):
f(3)=7(27)-23(9)+5(3)+3
189-207+15+3 = 0 OK!! we found another zero at x=3
Now, another synthetic division:
3⊥ 7 -23 5 3
21 -6 -3_
7 -2 -1 0
The quotient is a quadratic polynomial:
7x2-2x-1 This is not factorable, you need to apply the quadratic formula to find the 3rd and 4th zeros:
x= (1±2√2)÷7
The polynomial has 4 zeros at x=-2, 3, (1±2√2)÷7

step 2
Find the unit rate
we know that
In a proportional relationship the constant of proportionality k is equal to the unit rate of change or slope m of the line, because the line passes through the origin
so
The units rate of change is 9
That means------> A change of 1 unit in t correspond to a change of 9 units in d
