Answer:
A
Step-by-step explanation:
Median can be described as the number that occurs at the middle of a set of observations.
for example, in the set of numbers, 1 2 3 4 5, the median is 3
median = (first number + last number) / 2
If there are 29 students,
median = (1 + 29) / 2 = 30/2 = 15
the 15th students scored 84
and students between 1 - 14 scored lower than 84
so, 15 students scored an 84 or lower
What is the answer to the Brain Teaser below
Answer:
19
Step-by-step explanation:
The boots are the value of 10, since 3 equal 30. The man is the value of 5 since there are two men (10) and one boot (also 10) which made 20. The ribbon is the value of 4 since there is one man (5) and 2 ribbons (8 ) which made 13. add 10, 5 and 4 and you get 19.
Answer:
16
Step-by-step explanation:
From the first equation, I can infer that one pair of boots equals 10 because 10+10+10=30. Also, I can infer that just one boot equals 5 because there are 6 boots in total and 5+5+5+5+5+5=30
From the second equation, I can infer that one boy equals 5 because 2 boys which equal 10 plus one pair of boots which equals 10 is 20.
From the third equation, I can infer that one pair of ribbons is 4 because the boy equals 5 and 13-5=8. There are two pairs of ribbons so 8/2=4. I can also infer that just one ribbon is 2 because 8 divided by 4 individual ribbons is 2.
So, for the last equation, it would be 5+9+2 which the answer would equal 16. The one boot that would equal 5 plus the boy and 2 individual ribbons he's holding in his hands would equal 9 plus one ribbons which would equal 2 would all equal 16.
Hope this is helpful.
Paul and Mia have stamp collections. Paul has 446 stamps and Mia has 625 stamps. How many more stamps does Mia have?
Answer:
179
Step-by-step explanation:
Step 1: Subtract the lesser amount from the larger amount
[tex]625 - 446 = 179[/tex]
Therefore, Mia has 179 more stamps than Paul

Can you find the
triangle's perimeter
I’m marking branliest
Answer:
The perimeter would be 6x + 12
Step-by-step explanation:
The perimeter of a triangle is the sum of all its sides.
The measures of the sides of the given triangle are:-
3x + 2, x + 6 and 2x + 4
So, to find perimeter add these values together:-
3x + 2 + x + 6 + 2x + 4
Bring all the 'x' terms together first and then the other numbers so we can add them:-
3x + 2x + x + 2 + 6 + 4
6x + 12
The perimeter of the triangle would be 6x + 12AB = [tex]x[/tex] + 6
BC = 2 [tex]x[/tex] + 4
AC = 3 [tex]x[/tex] + 2
To find:-The perimeter of the triangle.
Solution:-[tex]{\boxed{\mathcal{\red{The\: perimeter \:of\:the\:triangle\:is\: 6x\:+\:12.\:✅}}}}[/tex]
Step-by-step explanation:-We know that,
[tex]\sf\pink{Perimeter\:of\:a\:triangle\:=\:Sum\: of\: all \:three\: sides}[/tex]
[tex] = AB + BC + AC \\ = x + 6 + 2x + 4 + 3x + 2 \\ = 6x + 12[/tex]

Show your work. a2 + b2 = c2
c is the side length of the hypotenuse. c2 is the hypotenuse side length multiplied by itself. You need to find the square root of the c2 value in order to solve for c.
We'll be using the Pythagoras property to solve this question.
According to the Pythagoras property,
H² = B² + P²H denotes hypotenuse
B denotes base
P denotes perpendicular
Here,
H = xP = 35 cmB = 12 cm→ (x)² = (35 cm)² + (12 cm)²
→ x² = 1225 cm² + 144 cm²
→ x² = 1369 cm²
→ x = √(1369 cm²)
→ x = 37 cm
Therefore, value of x is 37 cm.

15 > 2x – 9 > -23
The answer is 12>x>-7
Step-by-step explanation:
it's first divided into 2 parts
1 . 15 > 2x - 9
2. 2x - 9 > -23
Then solve them individually.
let's do it,
First half
15 > 2x - 9
15+9 > 2x
24 > 2x
24/2 > x
12>x
Second half
2x-9>-23
2x>-23+9
2x>-14
x>-14/2
x>-7
Joining of the two halves
We have :
12>x>-7

When you multiply a number by a fraction, the number always decreases. When you multiply a number by 1/2, it's always half of the original number
Step-by-step explanation:
For example, take 4 x 1/2. It can be written as four halves. What do we get when we add four halves together?
1/2 + 1/2 + 1/2 + 1/2 = 2!
2 is less than 4. It is also half of the number four
which equation best represent the line of fit that is drawn??
A)
y=0.8x+15
B)
y=1.0x+10
C)
y=1.6x+8
D)
y=–0.8x +12
Answer: Choice B
y=1.0x+10
==============================================================
Explanation:
Without the actual (x,y) coordinates for each point, it's nearly impossible to get the answer. However, we can note that the blue regression line is intersecting the y axis at y = 10 (or around there). So its very likely that the answer is y=1.0x+10 which is choice B
The equation y=1.0x+10 is in the form y = mx+b with,
m = 1.0 = slopeb = 10 = y interceptThe next best answer is y = -0.8x+12, since 12 is fairly close to 10. The y intercept portion isn't fully shown but again it appears the blue line is crossing at y = 10.

A line is perpendicular to x + 3y - 4 = 0 and has the same y-intercept as 2x + 5y - 20 = 0. Find the equation for the line.
This is equivalent to y = 3x+4 (slope intercept form)
By "standard form", I mean the form Ax+By+C = 0.
====================================================
Explanation:
Let's solve the first equation for y
x+3y-4 = 0
x+3y = 4
3y = 4-x
3y = -x+4
y = (-x+4)/3
y = (-x/3) + (4/3)
y = (-1/3)x + (4/3)
The equation is now in y = mx+b form, aka slope intercept form, with m = -1/3 as the slope and b = 4/3 as the y intercept. We'll focus on the slope.
Apply the negative reciprocal to this so that we go from -1/3 to +3/1 or simply 3. Flip the fraction and the sign. Note how -1/3 and 3 multiply to -1. Perpendicular slopes always multiply to -1, assuming neither line is vertical.
So this mystery perpendicular line we're after has a slope of 3.
It has the same y intercept as 2x+5y-20 = 0. Plug in x = 0 and solve for to determine the y intercept.
2x+5y-20 = 0
2(0)+5y-20 = 0
5y-20 = 0
5y = 20
y = 50/5
y = 4
The y intercept of 2x+5y-20 = 0 is y = 4, so it's also the y intercept of our final answer. Let b = 4.
-------------------------------------
We found that:
m = 3 is the slope of the perpendicular lineb = 4 is the y intercept of the perpendicular lineSo we know that,
y = mx+b
y = 3x+4
is the slope intercept form of the answer. Since your teacher gave you the equations in standard form (one version of it anyway), let's convert y = 3x+4 to that form as well
y = 3x+4
y-3x = 4
-3x+y = 4 .... one way to express standard form
-3x+y-4 = 0 .... another standard form
Some math textbooks use Ax+By = C as standard form, while others use Ax+By+C = 0. Unfortunately, it's a bit confusing because the same phrasing is used.

Hunter did not want to spend more than 150$ for a flight from Reno to Los Angeles. Write the inequality that models this situation and determine the first two possible solutions
Answer:
[tex](a)\ x < 150[/tex]
[tex](b)\ x = 149; x = 148[/tex]
Step-by-step explanation:
Given
[tex]Amount = 150[/tex] --- not more than
[tex]x \to[/tex] spending
Solving (a): Represent as an inequality
Not more than means <
So, the inequality is:
[tex]Spending < Amount[/tex]
[tex]x < 150[/tex]
Solving (b): The first two possible solutions
These are the numbers closest to 150 i.e. 149 and 148
Hence, [tex]x = 149; x = 148[/tex]
