Is (5,1) a solution of the system
Answers
Answer:no, (5,1) is not a solution for the equation. (1/7,1) will be a solution for the equation.
Step-by-step explanation:
one way to do it is to plug 1 as the y-value into the first equation which does work but when you plug 5 as the x-value and 1 as the y-value in the second equation, it will get you to 41 which does not match so it will not be an equation. the other way to check is to solve by substitution which for the first equation, you divide both side by -5 and get y=1 then substitute y with 1 in the second equation and subtract both side by 6 and get 7x=1 and divide both side by 7 to get 1/7. the y-value match but the x-value don't so (5,1) is not a solution.
A test of hypothesis is conducted to determine whether annual income and education level are independent. It is determined that the value of test statistic is 24.32 and the critical value of test statistics is 13.32. What specific conclusion can we draw about annual income and education level
Answers
Answer: We concluded that annual income and education level are not independent.
Step-by-step explanation:
For the given situation, the null and alternate hypothesis can be formulated as:
[tex]H_0:[/tex] annual income and education level are independent.
[tex]H_a:[/tex] annual income and education level are not independent.
Given, the value of test statistic is 24.32 and the critical value of test statistics is 13.32.
i.e. the test statistic value is greater than the critical value, thus we have enough evidence to reject the null hypothesis.
Therefore, we reject null hypothesis .
So , we concluded that annual income and education level are not independent.

B 241.5 in.?
C 258.75 in
D 286.5 in.?
Answers
Answer:
D.
Step-by-step explanation:
Given: Dimensions of a rectangular prism are [tex]7.5\,\,inches,3\,\,inches\,,\,11.5\,\,inches[/tex]
To find: total surface area of the rectangular prism in square inches
Solution:
Length of the rectangular prism (l) = 7.5 inches
Breadth of the rectangular prism (b) = 3 inches
Height of the rectangular prism (h) = 11.5 inches
Total surface area of the rectangular prism = 2(lb+bh+hl)
= [tex]2(7.5\times3+3\times11.5+11.5\times7.5 )[/tex]
[tex]2(7.5\times3+3\times11.5+11.5\times7.5 )=2(22.5+34.5+86.25)\\=2(143.25)\\=286.5\,\,square \,\,inches[/tex]

Answers
Answer:
6.
Step-by-step explanation:
2.3 repeating = 2 1/3
So 3 2/3 + 2 1/3
= 5 + 1
= 6.
Answer: 6
Step-by-step explanation:
[tex]3\frac{2}{3}+2.3^-[/tex]
Let's begin by converting the repeating decimal to a fraction and then to a mixed number.
Take the number:
[tex]2.3^-[/tex]
Let x (our result) be equal to that number.
[tex]x=2.3^-[/tex]
Multiply by 1 followed by as many zeros as repeating decimals; in this case 1. Therefore, 10.
[tex]10x=2.3^-*10[/tex]
This basically moves the decimal point one number to the right and since we have infinite 3's, we simply move 1 three and add another.
[tex]10x=23.3^-[/tex]
Subtract this and the original equation ([tex]x=2.3^-[/tex])
[tex]10x=23.3^-\\-x=2.3^-[/tex]
-----------------
10 - 1 = 9 and we have the same infinite repeating number 3, therefore they cancel out, leaving 23-2 = 21
[tex]9x=21[/tex]
Divide by 9
[tex]x=\frac{21}{9}[/tex]
Simplify by 3.
21/3=7
9/3=3
[tex]x=\frac{7}{3}[/tex]
Now, convert to a mixed number. To do this, divide.
7/3=2
6
-------
1
The 2 is the whole number, 1 is the numerator and 3 the denominator.
[tex]2\frac{1}{3}[/tex]
------------------------------------------------------------------------------------------------
Now we can solve this;
[tex]3\frac{2}{3}+2\frac{1}{3}[/tex]
Add the whole numbers and the fractions separately.
[tex](3+2)+(\frac{2}{3}+\frac{1}{3})[/tex]
[tex]5\frac{3}{3}[/tex]
3 and 3 can be simplied.
3/3=1
3/3=1
[tex]5\frac{1}{1}[/tex]
The result is 1, add this to the 5.
[tex]5+1=6[/tex]

The driving time varies inversely with the speed of the car if a certain trip takes 40 minutes when you travel 50 miles per hour how many minutes would it take if you travel 40 miles per hour
Answers
Answer:
It will take 50 minutes take if you travel 40 miles per hour
Step-by-step explanation:
The driving time varies inversely with the speed of the car i.e.
[tex]t\propto \dfrac{1}{v}[/tex]
or
[tex]\dfrac{t_1}{t_2}=\dfrac{v_2}{v_1}[/tex]
We have,
[tex]t_1=40\ min\\\\v_1=50\ mph\\\\v_2=40\ mph\\\\t_2=?[/tex]
Plugging all the values, we get :
[tex]t_2=\dfrac{t_1v_1}{v_2}\\\\t_2=\dfrac{40\times 50}{40}\\\\t_2=50\ min[/tex]
So, it will take 50 minutes take if you travel 40 miles per hour.
The number of minutes would it take if you travel 40 miles per hour is 50 minutes.
Calculation of the number of minutes:Since if a certain trip takes 40 minutes when you travel 50 miles per hour
So, the time for 40 miles per hour should be
[tex]= 40\times 50\div 40[/tex]
= 50 minutes
Therefore, The number of minutes would it take if you travel 40 miles per hour is 50 minutes.

The area of each triangular face is given by the formula ...
A = 1/2bh
The triangular faces have a base of b=8 cm, and a height of h=6 cm. Their area is ...
A = 1/2(8 cm)(6 cm) = 24 cm²
__
Each of the rectangular faces has a length of 20 cm. The width depends on which face is of interest. In each case, the area is given by ...
A = LW
Bottom face: A = (20 cm)(8 cm) = 160 cm²
Back face: A = (20 cm)(6 cm) = 120 cm²
Sloped face: A = (20 cm)(10 cm) = 200 cm²
__
The total area is the sum of the areas of all of the faces and bases. There are two triangular bases, so the total area is ...
(2×24 + 160 +120 +200) cm² = 528 cm²

Answers
Answer:
The man has been dead for 9 days. This is because this is the only day on the chart where all the types of insects coexist.
Step-by-step explanation:
5 species of insects were found at the same time alive on the dead man's body.
These 5 insects are then sent to the lab to be studied and larvae/eggs from them, raised under similar conditions to the conditions of the dead body.
The activity the eggs are them studied and presented in the chart provided
Insect/Day 1 2 3 4 5 6 7 8 9 10
Blowfly 1 1 1 1 1 1 1 1 1 0
Species A 0 0 0 0 1 1 1 1 1 1

Species C 0 0 0 0 0 0 0 0 1 1
Species D 0 0 0 0 0 1 1 1 1 1
Note that 0 represents a non-activity on the part of the egg of the insect specie.
From the chart, the first time all 5 insects coexist together at the same time just like they were found in the dead body is on the 9th day. Before the 9th day, all 5 insects do not coexist at the same time and even beyond the 9th day, on the 10th day, insect specie B stops existing.
So, it is evident that the man has been dead for 9 days as that's the only day on the chart where all the types of insects coexist.

The product of two consecutive natural numbers is 19 greater than their sum. Find thee numbers.
Answers
Answer:
The numbers are suppose to be natural numbers that is positive integers form 1 upward. So the numbers will be 5 and 6.
Step-by-step explanation:
The product of 2 consecutive natural numbers is 19 greater than their sum . We need to understand important terms in this question like consecutive and natural numbers.
Consecutive numbers are numbers that follows each other continuously from smallest to largest. Natural numbers are numbers that includes all the positive numbers from 1 to infinity example 1, 2, 3, 4............infinity.
Let the consecutive number be a and a+1.
The product of this 2 numbers are when you multiply them. Therefore,
a(a + 1) = a² + a
The sum of the 2 numbers are their addition. Therefore,
a + (a + 1) = 2a + 1
The product is 19 greater than the sum. This means the product of this numbers minus the sum of this numbers is equals to 19.
a² + a - (2a + 1) = 19
a²+ a - 2a - 1 = 19
a²- a - 20 = 0
Find the numbers that can be multiplied to get -20 and added together to get -1. The numbers are 4 and -5
a² + 4a - 5a - 20 = 0
a(a + 4) - 5(a + 4) = 0
(a + 4)(a - 5) = 0
a = - 4 and a = 5
The numbers are suppose to be natural numbers that is positive integers from 1 upward. So the numbers will be 5 and 6.
To prove it
5 × 6 = 30(products)

Answers
We have been given graph of function [tex]y=f(x)[/tex]. We are asked to find the value of [tex]f^{-1}(6)[/tex] from the graph of [tex]y=f(x)[/tex].
We know that to find an inverse function is a function that reverses another function. A function f(x) gives an output of y, when we input some value of x. The inverse of f(x) will give the same value of x from value of y.
So to find inverse of a function we need to switch all x and y values.
We can see that [tex]f(4)=6[/tex], so to to find value of [tex]f^{-1}(6)[/tex], we have to switch x and y values.
After switching x and y values, we will get:
