Let f(x)=2x^4+x^3+x^2-3x+r. For what value of r is f(2)=0?
Answer:
the answer is 0
Step-by-step explanation:
Answer:
r = -38
Step-by-step explanation:
For what value of r in the formula: f(x) = 2x4 + x3 + x2- 3x + r does f(2) = 0?
Replace x with 2: 2·24 + 23 + 22- 3·2 + r = 32 + 8 + 4 - 6 + r = 38 + r
This value is to equal 0: 38 + r = 0
r = -38

Angela collected the data displayed in the table below.
-8,6.2,2.5,12,-2,-1.3,15,-2,0,7
What is the mean absolute deviation for this set of data?
A 2.94
B 1.25
C 4.59
D 5.688
Answer: A
2.94
Step-by-step explanation:
add all the numbers together -8+6.2+2.5+12+-2+-1.3+15+-2+0+7=29.4.
next you divide 29.4 by how much numbers there are in the equation which in this case its 10.
29.4/10=2.94
so its A :)
The mean absolute deviation of the given data set is 5.688 so option (D) will be correct.
What is the mean absolute deviation?The average distance between an observation's mean and its variance is shown by the mean absolute deviation, a measure of b. mean makes understanding simpler by using the data's original units.
Given the data set ;
-8,6.2,2.5,12,-2,-1.3,15,-2,0,7
Mean of this data set ;
Mean = (-8 + 6.2 + 2.5 + 12 - 2 - 1.3 + 15 - 2 + 0 + 7)/10
Mean = 29.4/10 = 2.94
Now,
Mean absolute deviation is given by ;
MAD = Σ |x - m|/n where x is the data value while n is a number of data and m is the mean.
So,
MAD = |-8 - 2.9 | + | 6.2 - 2.9| + |2.5 - 2.9| + .. so on / 10
MAD = 56.688/10
⇒ 5.688
Hence "The mean absolute deviation of the given data set is 5.688".

Christel wants to know what the most popular color at her school is. She surveys students grades 1,2,3.
Will the sample be representative or biased? And can you please explain how that answer works. Thx! :)
Answer:
It will be biased.
Step-by-step explanation:
By surveying only grades 1, 2, and 3, she is not taking a representation of the entire school. It is possible that the popular color or the color the students like would change over time and the opinion of the younger kids could be different from that of the older kids. Therefore, the sample is biased unless she surveys students from all grades.

Match the two numbers with their least common multiple (LCM). (6 points)
1.
8 and 4
2.
8 and 10
3.
8 and 6
a.
8
b.
24
c.
40
Answer:
1. 4 = 2× 2, 8 = 2 × 2 × 2
LCM of 4 and 8 = 2 × 2 × 2 = 8
The correct answer is a.
2. 8 = 2 × 2 × 2, 10 = 2 × 5
LCM of 8 and 10 = 2 × 2 × 2 × 5 = 40
The correct answer is c.
3. 6 = 2 × 3, 8 = 2 × 2 × 2
LCM of 6 and 8 = 2 × 2 × 2 × 3 = 24
The correct answer is b.
- 1/2 - 2/3v = 4/5 please help
Answer:
-39/20 (decimal is -1.95)
Step-by-step explanation:
First, you have to isolate the variable term (-2/3v). You can do this by moving -1/2 to the other side. Then, the right side would be 4/5+1/2. Make this side common by changing the denominators to being the same thing (8/10+5/10=13/10). Now, we know that 13/10 is equal to -2/3v. You can then divide both sides by -2/3 to get v. If you're lazy like me, just use a calculator to divide 13/10 by -2/3. What you get then is your answer!
Hope this helps! Please mark me as brainliest!
Answer:
v = - 39/20
Step-by-step explanation:
-1/2 - 2/3v = 4/5
-2/3v= 4/5 + 1/2
-2/3v = 8/10 + 5/10
-2/3v = 13/10
v = 13/10 * -3/2
v = - 39/20
Hope this helps!

-20y+16y= -4y
-4y+15=2+11
-11
-4y+4=2
-4
-4y=2
÷-4
y=-2
Answer:
The answer is y = 1/2
Step-by-step explanation:
-20y + 15 = 2 - 16y + 11 <----This is the original problem.
-20y + 15 = 13 - 16y <----- Use the commutative property and addition.
-20y + 15 = 16y -13 <-----Use commutative property.
-20y + 15 - 15 = 16y - 13 - 15 <----- Subtract 15 from both sides.
-20y = 16y - 2 <----- Simplify
-20y + 16y = 16y - 2 + 16y <------Add 16y to both sides.
-4y = -2 <---- Simplify
-4y/-4 = -2/-4 <---- Divide both sides by -4
y = 1/2

Answer Counterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axis explanation the given figure has vertices p(1,2),q(2,1),r(3,2),s(3,3)recall that for counterclockwise rotation about the origin, (x,y)\rightarrow (-x,-y)when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will become p1( - 1, - 2),q1( - 2, - 1),r1( - 3, - 2),s1( - 3, - 3)next, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,p'(1, - 2),q'(2, - 1),r'(3, - 2),s'(3, - 3)

All the while the dog sat in the snow, its wolf-brush of a tail curled around warmly over its forefeet, its wolf-ears are forward intently as it watched the man. And the man, as he beat and threshed with his arms and hands, felt a great surge of envy as he regarded the creature that was warm and secure in its natural covering.
Why is the man envious of his dog? Make sure to explain his reasoning for being jealous.
Answer:
The man is envious because he's jealous of the dog's fur. For he has natural covering and is kept warm because of it. The man has to wear several layers of clothing to be warm while the dog is warm enough with his fur/natural covering.

The list shows the number of songs that five students each downloaded last week.
32, 43, 38, 28, 51
What is the mean absolute deviation of the numbers in the list?
F 34.4
G 6.88
H 38.4
J 7.68
Answer:
g)6.88
Step-by-step explanation:
We’ll begin by finding the mean of the data set.
32+43+38+28+51=192 then 192/5=38.4
Then find the absolute value of the difference between each data value and the mean.
l32-38.4l=6.4
l43-38.4l=4.6
l38-38.4l=0.4
l28-38.4l=10.4
l51-38.4l=12.6
Lastly, find the sum of the absolute values and divide by the number of the values
6.4+4.6+0.4+10.4+12.6=34.4
34.4/5=6.88
