Answer:
the median for A is 26 and the mean for B is 24
Step-by-step explanation:
since 24 and 28 are both in the middle we need to find the mean of 24 and 28 to find A's median.
18+19+21+25+29+32=144
144 divided by the # of terms 6 gives our mean 24 for B.

What are the solutions to the system of equations?
x² + y² = 5
y= 2x
Answer:
(x1, Y1) = ('1, '2) (x2, Y2) = (1,2)
Step-by-step explanation:
Which of the following statements correctly illustrate the addition property of equality?
Check all of the boxes that apply.
If a = b, then a + c = b + c.
If x = y, then x + 2 = y- 2.
If w + 2 = 7, then w + 2-2 = 7- 2.
Answer: The first one and the third one
Step-by-step explanation:
The first one because a+c would equal the same as b+c due to the fact that a and b are equal. The second one would be because when solving for w+2=7 then you would subtract 2 from both sides and get 5 and the second one states after being simplified that w=5

A man spends 2/5 of his salary on food, 3/10 on his rent and 1/8 on other expenses. What fraction of his salary is still left with him?
Answer:
[tex]\frac{7}{40}[/tex]
Step-by-step explanation:
[tex]1-(\frac{2}{5}+\frac{3}{10}+\frac{1}{8})[/tex]
[tex]1-\frac{33}{40}[/tex]
[tex]\frac{7}{40}=0.175[/tex]
Answer:
7/40 is still left with him.
Step-by-step explanation:
LCM 5,10,8 = 40
2/5 = (x8) = 16/40 = food
3/10 = (x4) = 12/40 = rent
1/8 = (x5) = 5/40 = other expenses.
16/40 +12/40 + 5/40 = 33/40
40/40 - 33/40 = 7/40
What is the explicit formula for the sequence?
7, 2, –3, –8, –13, . . .
===========================================================
Explanation:
[tex]a_1 = 7[/tex] is the first term
[tex]d = -5[/tex] is the common difference, telling us to add -5 to each term to get the next term. This is the same as subtracting 5 from each term
The nth term of the arithmetic sequence is,
[tex]a_n = a_1 + d(n-1)\\\\a_n = 7 + (-5)(n-1)\\\\a_n = 7-5(n-1)\\\\a_n = 7-5n+5\\\\a_n = -5n+12\\\\[/tex]
----------------
As a check, let's plug in n = 4 and we should get -8 as our fourth term
[tex]a_n = -5n+12\\\\a_4 = -5(4)+12\\\\a_4 = -20+12\\\\a_4 = -8\\\\[/tex]
so that confirms that portion of the sequence. I'll let you check the other values.

the triple of the area of a square is 1587 m2 What is the side of the square?
Answer:
23 m
Step-by-step explanation:
Given that triple the area = 1587 m² , then
area = 1587 ÷ 3 = 529 m²
The area of a square = s² ( s is the measure of the side ), thus
s² = 529 ( take the square root of both sides )
s = [tex]\sqrt{529}[/tex] = 23 m

You are a judge and the following case have come before you. Apply the Rule and make a decision as to whether these "vehicles" can drive through the park. Explain your reasoning.
An ambulance has a dying car accident victim in it and is racing to the hospital. The shortest route is through the park, so the ambulance drives through.
Well, my decision would be to let these kinds of vehicles like ambulances, police cars, fire-fighter trucks, etc., drive through the park. The reason I'd decide to let these vehicles drive through the park is because, well, you never know if someone is in critical danger and needs urgent assistant. If the shortest route to get to the person is through the park, it'd be reasonable and understandable because you don't want that person do get hurt do you?
so sorry if I went a bit off. Although, I hope this helped, have a great day!

find the area of this figure
Answer: 49.12 ft²
Step-by-step explanation:
To find the area of this figure, we can separate it into 2 parts. We can find the area of the semi circle and the area of the triangle. Then we add together to areas.
Area of Triangle
A=bh/2
A=6(8)/2
A=48/2
A= 24 ft²
Area of Semi Circle
A=πr²/2 (Divide by 2 because semi circle is half of a circle, so we divide the area by 2)
A=π(4)²/2
A=(3.14)(16)/2
A=25.12 ft²
Total area
A=24+25.12=49.12 ft²
Travis has the following problem for homework:
82 - 16 x 4 + 18+ [(36/6) - 2]
His neighbor, Ted, says "just solve it working left to
right." Ted gets an answer of 51.
What is the correct answer? (Hint: Ted doesn't know
PEMDAS).
Answer:
The correct answer is -4
Step-by-step explanation:
First you have to solve what is in the parenthesis. So do 36/6 which is 6 and then subtract 2 to get 4. Then you have to do the multiplication so 16 x 4 and you get 64. then you can go left to right. 82-64+18+4 and when you do that you get -4
A picture was marked at $90.00. It was sold at 3/4 of its marked price. What was the sale price?
Answer: $67.50
Step-by-step explanation:
Marked price = $90
It is sold at 3/4 of marked price
3/4 of 90
3*4 x 90 = 135/2
= 67.50 = sale price
find the slope of the line that passses thruogh 1,5 and 10,9
Answer: The slope is 4/9 or -4/-9.
Step-by-step explanation:
(1,5)
(10,9) Find the difference in the y values and divide it by the difference in the x values.
5-9= -4
1- 10= -9
-4/-9= 4/9
so the slope is 4/9
Using the slope we could also find the y-intercept and write the equation.
5=4/9 (1) + b where b is the y-intercept
5= 4/9 + b
-4/9 -4/9
b= 41/9
Now we will have the equation y= 4/9 + 41/9

The function ƒ(x) = 4x + 1 is transformed to g(x) = 2x + 1. What type of transformation has occurred? A) Reflection and Vertical Translation B) Rotation C) Reflection D) Rotation and Vertical Translation
Answer:
B) Rotation
Step-by-step explanation:
The only difference between functions f(x) and g(x) is the slope. To get from f(x)=4x+1 to g(x)=2x+1, you would need to rotate slightly clockwise about point (0,1) - the y-intercept. This would make the graph less steep (2x is less steep than 4x) while still retaining the (0,1) y intercept.
Answer:
Rotation
