The number of writing instruments in some teachers' desks is displayed in the dot plot. Which is greater the mean or the median? Explain your reasoning using the shape of the distribution.
Answer:
the median is greater.
Step-by-step explanation:
the median would be 2 when you take the average of the middle two numbers. the mean would be 1.75 when you average all of them. 2 is greater.
Answer:
Median is greater than the mean
median = 9.5
mean = 9
Step-by-step explanation:
The shape of the distribution is skewed right, so the median will most likely have a higher value than the mean
A recipe for fluffy slime calls for 3 % cups of shaving

would you need if you were making enough slime
for ten people?

Which of the following equations has a slope of 3?
O 6x - 2y = 5
O 3x + 4y = 12
O y = 4x + 3
The answer 6x - 2y = 5
Step-by-step explanation:
The general formula of linear equations is y = mx + c
where m is the slope
so when we put this in the general form, it will be
-2y = -6x + 5
y = 3x - 5/2
and so the slope is 3

Ankit's father is five years older than three times of Ankit's age. 50 years old, then calculate the present age of Ankit
Step-by-step explanation:
Let,
Ankit's age = x
So, ankit's father's age = 3x + 5
Given,
Age of Ankit's father's age = 50
Therefore,
By the problem,
=> 3x + 5 = 50
=> 3x = 50 - 5
=> 3x = 45
[tex] = > x = \frac{45}{3} [/tex]
=> x = 15
Hence,
Present age of Ankit is 15 years (Ans)

Which is a prime number?
A.0
B.1
C.3
D.9
Answer:
3
Step-by-step explanation:
NotePrime numbers are numbers that have two factors thus 1 and the number itself . Example; 2 ,3,5 ,7 and 11
BesidesAlso 0 and 1 is not a prime number
Answer:
C. [tex]\displaystyle 3[/tex]
Step-by-step explanation:
Prime Numbers consist of two factours -- 1 and that number. Just so you know, you can AUTOMATICALLY eliminate the first two choises because those two numbers are not composite nor prime. Now, I can predict that your next lesson will probably be about prime factorisation, in which you have to find the prime factorisation of numbers, using two methods:
Factour TreeLadder DiagramFactour Tree Ladder Diagram
3 3|3
| ⁻⁻
3 1
Factour Tree Ladder Diagram
9 3|9
/\ ⁻⁻
3 3 3|3

So, the prime factorisation of 9 is [tex]\displaystyle 3^2,[/tex]and the prime factorisation of 3 is 3.

Evaluate each function. Step by step.
1) k(t) = -2|3t| + 2; Find k(-5)
2) g(n)=-3n^2+3+2n; Find g(-3)
Answer:
Substitute what t and n equals to in the equation and just solve using algebra.
So number 2, plug in -3 where ever the variable N is located in and solve.
g(-3) = 3(-3)^2+3+2(-3) ---> g(-3) = 27+3-6 ---> g(-3) = 24 That's the answer for 2.
For 1
plug in -5 into the t variable and solve.

Answer:
x=15 y=3
Both (4x+10y) and (6x) equal 90 degrees, as angle 4x+10y is vertical to a 90 degree right angle, and angle 6x is directly beneath the right angle, making it equivalent. To find x, you simply do 90/6, which is 15, meaning x=15. Now plug in that into 4x+10y=90, which will make it 60+10y=90. Subtract 60 from 90, and divide the difference, 30, by 10, giving you 3, thus showing that y=3. You can double check by plugging in the x and y values.

and give me an explanation if you can (optional).
THANK YOU!!!!
Answer:
Kamille paid $34.88 for her outfit after tax.
Ms. Roth will pay $59.16 in total.
Step-by-step explanation:
Kamille brought a new outfit that cost $32.00. The tax rate is 9%. How much did she pay for the outfit after tax?
32.00 x 0.09 = 2.88
32 + 2.88 = 34.88
Ms. Roth went to I-Hop for breakfast. She ordered pancakes for $5.00, eggs for $3.50, and orange juice for 42.50. if she tips the waiter 16%, how much will she pay in total?
5 + 3.5 + 42.50 = 51
51 x 0.16 = 8.16
51 + 8.16 = 59.16

Justify the equation by stating one of the properties of real numbers.
x + (37 + (-37)) = x + 0
Answer:
The property is the neutral element, in this case, it's the 0
The equation is justified using the additive inverse property of real numbers. The equation [tex]\(x + (37 + (-37)) = x + 0\)[/tex] is justified by the additive inverse property of real numbers.
According to the additive inverse property, for any real number a, there exists another real number -a such that their sum is equal to zero:
[tex]\(a + (-a) = 0\)[/tex]
In the given equation, 37 and -37 are additive inverses of each other, meaning [tex]\(37 + (-37) = 0\).[/tex] Therefore, the equation simplifies to:
[tex]\(x + (37 + (-37)) = x + 0\)\(x + 0 = x\)[/tex]
So, the equation is justified using the additive inverse property of real numbers.
