Which model represents a percent error of 25%? A model with 12 squares labeled exact value and 3 squares labeled error. A model with 10 squares labeled exact value and 5 squares labeled error. A model with 9 squares labeled exact value and 3 squares labeled error. A model with 8 squares labeled exact value and 4 squares labeled error.
Answer:
A model with 12 squares labeled exact value and 3 squares labeled error.
Step-by-step explanation:
The proportion of error is the number of errors divided by the number of trials. The percentage is the proportion multiplied by 100.
A model with 12 squares labeled exact value and 3 squares labeled error.
3/12 = 0.25
0.25*100 = 25%
This is the answer.
A model with 10 squares labeled exact value and 5 squares labeled error.
5/10 = 0.5
0.5*100 = 50%
A model with 9 squares labeled exact value and 3 squares labeled error.
3/9 = 0.3333
0.3333*100 = 33.33%
A model with 8 squares labeled exact value and 4 squares labeled error.
4/8 = 0.5
0.5*100 = 50%

solve the equation x^4+7x^2-18=0 and express each solution in a+bi form
Answer:
The following are the solutions found for x:
+√2 + 0i
-√2 + 0i
0 + 3i
0 - 3i
Step-by-step explanation:
The given equation is:
x⁴ + 7x² - 18 = 0
Rewrite x4 as (x²)²
(x²)² + 7x² − 18 = 0
Let u = x²
u² + 7u − 18 = 0
Factorize:
u² + 9u - 2u - 18 = 0
u(u+9) -2(u+9) = 0
(u-2)(u+9) = 0
(x²-2)(x²+9) = 0
Seperate both equations:
x² - 2 = 0 x² + 9 = 0
x = ±√2 x = ±√-9
x = ±√2 x = ± 3√-1
x = ±√2 + 0i x = 0 ± 3i

How many integers are between sqrt 37 and 5*sqrt 11?
Answer:
There are 10 integers between the given values
Step-by-step explanation:
We start by finding approximations of the two real values given that include square roots of non-perfect-square numbers:
[tex]\sqrt{37} \approx6.0827[/tex]
then this point is located in between the integers 6 and 7 on the x-axis.
[tex]5\,\sqrt{11} \approx 16.58[/tex]
therefore, it is located between the integers 16 and 17 on the number line.
Then between [tex]\sqrt{37}[/tex], and [tex]5\,\sqrt{11}[/tex], we have the following integers:
7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
That is 10 integers

Find the inequalities which describe the regions that’s shaded
Answer:
The lines that make up this region are y = 5 (light blue line), x = 2 (green line) and y = x (purple line). The graph tells us that the answer is y ≤ 5, y ≥ x and x ≤ 2.
Answer:
Green: x is less than or equal to 2
Purple: y is greater than or equal to x
The horizontal line near the top is y=6, so the blue shaded area below is y is less than or equal to 6
Step-by-step explanation: Solid lines mean equal to or < >
Sorry my keyboard doesn't have the real symbol for those.
Since the y-intercept for the purple area is 0, there is no constant to enter in the slope-intercept form: y=mx+b And since the slope is 1, there is no coefficient with x.

Select the statements that are true.
Answer:A And B
Step-by-step explanation:
The true stetement is:
The standard deviation of B is greater than the standard deviation of A.
1. The interquartile range (IQR) is a measure of the spread of the data. Since the new brand with only 74% of kernels popped has the lowest percentage, including it in the data set B would likely increase the range of values and therefore increase the interquartile range.
Therefore, this statement is false.
2. The mean is affected by the values of the data set, and including the package with the least kernels popped in data set B would likely lower the overall mean compared to data set A. Therefore, this statement is false.
3. Adding the package with the least kernels popped to data set B might shift the median to a lower value compared to data set A. Therefore, this statement is false.
4. Including the package with the least kernels popped in data set B would increase the spread of the data because it introduces a lower value compared to the other percentages. Therefore, this statement is false.
5. Including the package with the least kernels popped in data set B would likely increase the variability and spread of the data, leading to a greater standard deviation compared to data set A.
Therefore, this statement is true.
6. Including the package with the least kernels popped in data set B would likely shift the center of the data towards a lower value due to the lower percentage. Therefore, this statement is false.

A catcher's and a pitcher's uniform numbers are consecutive integers whose product is 306. If the catcher's was the smaller number, determine the uniform number of each player. catcher's number pitcher's number
Answer:
Catcher's number = 17
Pitcher's number = 18
Step-by-step explanation:
Let two consecutive numbers be represented by x and (x + 1)
Hence,their product
= x(x + 1) = 306
= x² + x - 306 = 0
We factorise
= x² + 18x - 17x - 306 = 0
= x(x + 18) - 17(x + 18) = 0
= (x + 18)(x - 17) = 0
x + 18 = 0 = -18
x - 17 = 0 = 17
x = 17 and -18
Our answer can't be a negative integer
Hence x = 17
The second consecutive integer = x + 1
= 17 + 1 = 18
Hence the uniform numbers are 17 and 18.
We are told in question that: If the catcher's was the smaller number, determine the uniform number of each player.
Therefore,
The Catcher's uniform number = 17
The Pitcher's uniform number = 18

A graph is a way to represent a lot of data in a visual format. The graph which correctly displays the data from the list and table is graph c.
What is a graph?A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
The bar graph that can represent the given situation will have the name of the color pattern on the x-axis, while the number of students who choose the pattern will be listed on the y-axis.
Since the last pattern is the yellow pattern, therefore, it should be on the leftmost side of the equation and must have the smallest candle. while the first candle should be the second-largest candle as it is selected by only four students. Since the second candle and the third candle has the value of 6 and 12. Therefore, the length of the third candle should be half of the length of the second candle.
Now, the only graph that fits these criteria is graph C.
Hence, the graph which correctly displays the data from the list and table is graph c.

Red: 3 inches
Orange: 4 inches
Yellow: 5 inches
Green: 7 inches
Blue: 9 inches
Purple: 12 inches
1. How many triangles can she make with them if each side is a different color? List the combinations that work.
2. Karen was just trying different combinations of colored rods one at a time, placing the colored rods together to see if they make a triangle. What method did you use to determine the triangle options? Which method do you think is better and why?
Answer:
9 possible combinations: RGB, RYG, RGB, OYG, OGB, OBP, YGB, YBP, GBP
Step-by-step explanation:
We need to consider The Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.Let's see what are the possible combinations:
3+4= 7 so possible 3rd side is 5
3, 4, 5 or ROY3+5= 8 so possible 3 rd side is 7
3, 5, 7 or RYG3+7= 10 so possible 3rd side is 5 or 9 (5 is repeat of the one above)
3, 7, 9 or RGB3+9= 12 so possible 3rd side is 7, see one above
3+12= 15 so possible 3 rd side is none
4+5=9 so possible 3rd side is 7
4, 5, 7 or OYG4+7= 11 so possible 3rd side is 9
4, 7, 9 or OGB4+9= 13 so possible 3rd side is 12
4, 9, 12 or OBP5+7= 12 so possible 3rd side is 9
5, 7, 9 or YGB5+9= 14 so possible 3rd side is 12
5, 9, 12 or YBP7+9= 16 so possible 3rd side is 12
7, 9, 12 or GBPSo the possible 9 combinations are:

a. The value will be greater than 1 because (negative 3) divided by (negative 9) is a positive number. A number in scientific notation with a positive exponent has a value greater than 1.
b. The value will be greater than 1 because (negative 3) minus (negative 9) = 6. A number in scientific notation with a positive exponent is greater than 1.
c. The value will be less than 1 because 5.68 divided by 8.54 is less than 1. The negative exponents will make it even smaller.
d. The number will be less than 1 because 5.68 times 10 Superscript negative 3 is a very small number and division always makes the size of a number smaller.

Step-by-step explanation:
[tex]900 \times (1+0.6\%)^5[/tex]
[tex]900 \times (1+0.6/100)^5[/tex]
[tex]900 \times (1+0.006)^5[/tex]
[tex]900 \times (1.006)^5[/tex]
[tex]900\times \:1.03036[/tex]
[tex]927.32594[/tex]
Answer:

Step-by-step explanation:
Total Population = 900
Annual rate of increase = 0.6 % of 900
=> [tex]\frac{0.6}{100}* 900[/tex]

Use the method of equating coefficients to find the values of a, b, and c: (x+4)(ax2+bx+c)=2x3+9x2+3x−4
Answer:
[tex]a = 2; b = 1\ and\ c = -1[/tex]
Step-by-step explanation:
Given
[tex](x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
Required
[tex]Find\ a,b,c[/tex]
[tex](x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
Open Bracket
[tex](x)(ax^2+bx+c)+(4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
[tex]ax^3+bx^2+cx+4ax^2+4bx+4c=2x^3+9x^2+3x-4[/tex]
Collect like terms
[tex]ax^3+bx^2+4ax^2+cx+4bx+4c=2x^3+9x^2+3x-4[/tex]
By comparing coefficients; we have
[tex]ax^3=2x^3\\bx^2+4ax^2=9x^2\\cx+4bx=3x\\4c=-4[/tex]
Remove all traces of x from both sides
[tex]a=2\\b+4a=9\\c+4b=3\\4c=-4[/tex]
From the first equation;
[tex]a = 2[/tex]
From the last equation
[tex]4c = -4[/tex]
Divide both sides by 4
[tex]\frac{4c}{4} = \frac{-4}{4}[/tex]
[tex]c = \frac{-4}{4}[/tex]
[tex]c = -1[/tex]
Substitute -1 for c in the third equation
[tex]c+4b=3[/tex]
[tex]-1 + 4b = 3[/tex]
Add 1 to both sides
[tex]1-1 + 4b = 3+1[/tex]
[tex]4b = 4[/tex]
Divide both sides by 4
[tex]\frac{4b}{4} = \frac{4}{4}[/tex]
[tex]b = \frac{4}{4}[/tex]
[tex]b = 1[/tex]
Substitute 2 for a in the second equation [To confirm the value of b]
[tex]b+4(2)=9[/tex]
[tex]b + 8 = 9[/tex]
Subtract 8 from both sides
[tex]b + 8 - 8 = 9 - 8[/tex]
[tex]b = 1[/tex]
Hence;
[tex]a = 2; b = 1\ and\ c = -1[/tex]

3rd term=(3)^-5 = 1/243
So, 10th term will be (10)^-5=1/100000
The first term is -4, second term is -1, third term is 4 and 10th term is 95.
What is sequencea group of connected actions, moves, or things that happen in succession and have a specific order.
Given that,
The nth term of sequence = n² - 5 (1)
To find terms, Substitute values of n in equation (1),
Substitute n=1, the first term = 1-5 = -4
Substitute n=2, the second term = 4-5 = -1
Substitute n=3, the third term = 9-5 = 4
For 10th term, substitute n= 10,
10th term = 100-5 = 95
First term =-4, second term = -1, third term = 4 and 10th term = 95.
