Mean= 5
Median= 4
Mode= No mode
Range= 9
is {(-7,8),(5,-5),(-7,-3)(3,-4,)} a relation a function
yes or no
Answer:
Step-by-step explanation:
A function can only have one y value for any given x value. If there is more than one value of y for a single x value it is said to have failed the ‘vertical line test.
Since there are points (-7,8) and (-7,-3) this is NOT a function.

Answer:
Step-by-step explanation:
1. I can't see the first one very well.
2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]
3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.
We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'
Work out the area by doing 1/2(2+6)4 = 16' squared.
4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.
To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.
The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared
Which of the following expressions are equivalent to x+y+z
A: z+y+x
B: x+z-y
C: none of above
Need help
The first option is correct. As long as the signs remain the same for the specific terms, it's correct.
x+y+z is equivalent to z+y+x
Solve for x. Rounds the answers to the nearest tenth.

Answer: there is no solution
Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13
Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution

6.Write the equation of the line in slope-intercept form that has a slope of -4 and passes through the point (-1, -3).
Answer:
y = - 4x - 7
Step-by-step explanation:
Line is passing through the point (-1, - 3) and has a slope (m) = - 4
[tex]y - ( - 3) = - 4 \{x - ( - 1) \} \\ \\ y + 3 = - 4(x + 1) \\ \\ y + 3 = - 4x - 4 \\ \\ y = - 4x - 4 - 3 \\ \\ y = - 4x - 7[/tex]
Hi! I am trying to solve this question for a homework assignment, but I can’t figure out what the answer is. Can someone please help?
In a scientific journal, we read that a certain substance weighs 0,000,418 grams.
Write this number in scientific notation.
Answer:
4.18 × 10^ 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
I am assuming that number began with a decimal point.
Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes
4.18X10^(-5)

11. One-third of the result of three times a number that is increased by 12
Answer:
n * 3 +12 / 3
Step-by-step explanation:
One third of the result of a number * 3 is once the number is multiplied by 3, the number is then added to 12, because the result is divided by 3, meaning you must multiply by 3 first, then add 12, and then divide by 3.
Equation formed will be:
1/3 (3x + 12)

36.Find the following using suitable identities.
a) (7a – 4b) (7a + 4b)
b) 501 x 502
Would appreciate if you send a pic of the solutions<3
Answer:
1) [tex]49 {a}^{2} - 16 {b}^{2} [/tex]
2) [tex]251502[/tex]
Step-by-step explanation:
a) Question :-[tex](7a - 4b)(7a + 4b)[/tex]
Identity used here :-[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
So,
[tex](7a + 4b)(7a - 4b)[/tex]
[tex]=> {(7a)}^{2} - {(4b)}^{2} [/tex]
[tex]=> 49 {a}^{2} - 16 {b}^{2} [/tex]
b) Question :- [tex]501 \times 502[/tex]
Identity used here :-[tex](x + a)(x + b) = {x}^{2} + (a + b)x + ab[/tex]
So,
[tex]501 \times 502 = (500 + 1)(500 + 2)[/tex]
[tex] = > {(500)}^{2} + (1 + 2)500 + 1 \times 2[/tex]
[tex] = > 250000 + 1500 + 2[/tex]
[tex] = > 251502[/tex]

Write a quadratic polynomial, sum and product of whose
zeroes are -4 and -21 respectively.
Answer:
x^2 -4x -21
Step-by-step explanation:
Here, we want to write a quadratic polynomial
We have the sum as -4
Let us have x as the variable
so the sum of the variables is -4x
while the product is -21 x^2
Two factors of 21 that can work here is -7x and 3x
So we have
x^2 - 7x + 3x -21
= x^2 -4x -21
i hate geometry if someone could help me i would appreciate it so much
Answer:
Step-by-step explanation:
150 + 150 + x = 360
x = 60
∠ADC = 60°
they are the same
360 can be written as 2^x * 3^y * 5, where x and y are positive integers.
Work out the value of x and the value of y.
Answer:
x = 3, y = 2
Step-by-step explanation:
[tex]360 = {2}^{x} \times {3}^{y} \times 5 \\ \\ \frac{360}{5} ={2}^{x} \times {3}^{y} \\ \\ 72 = {2}^{x} \times {3}^{y} \\ \\ 8\times 9 = {2}^{x} \times {3}^{y} \\ \\ {2}^{3} \times {3}^{2} = {2}^{x} \times {3}^{y} \\ \\ equating \: like \: terms \: on \: both \: sides \\ {2}^{3} = {2}^{x} \\ \\ \implies \: x = 3 \\ \\ {3}^{2} = {3}^{y} \\ \\ \implies \: y= 2 \\ \\[/tex]
