Coco buys a very large rectangular chocolate bar and decides that each day, she
will cut the largest possible square off of the bar and eat it. When the remaining
part of the chocolate bar is a square, she will eat all that is left. The table shows
the area, in square centimeters, of the square Coco eats on each day. If Coco
finishes the chocolate bar on Day 6, what was the length of the longer side of the
chocolate bar when Coco bought it?
Table is included need answer ASAP.

Answer: 39
Step-by-step explanation:
On each of the six days Coco ate a square piece of chocolate with side length 15 cm, 15 cm, 9 cm, respectively. Then find the slope versus. 15*15+9*1=236. Then you have to do 236-200=36. Later 36+3, since there were three numbers to get 39.

In a distribution, a score of X=60 has a z-score of -3.0.. A score of X=85 has a z-score of 2.0. What are the mean and standard deviation for this population?
Answers
[tex]z=\frac{X- \mu}{\sigma}[/tex]
We don't have μ, the mean, or σ, the standard deviation. We can, however, set up a system of two equations with the information we do have. We know:
[tex]-3=\frac{60- \mu}{\sigma} \text{ and } 2=\frac{85- \mu}{\sigma}[/tex]
We can make this look more like a "typical" system of equations by cancelling the fractional part of each equation. We do this by multiplying the bottom of each equation by σ:
[tex]-3*\sigma=\frac{60- \mu}{\sigma}*\sigma \text{ and } 2*\sigma=\frac{85- \mu}{\sigma}*\sigma \\ \\-3\sigma=60- \mu \text{ and } 2\sigma=85- \mu[/tex]
Now we'll get the variables on the same side of the equation. We'll do this by adding μ to both sides:
[tex]-3\sigma + \mu=60- \mu + \mu \text{ and } 2\sigma+ \mu =85- \mu + \mu \\ \\-3\sigma+\mu=60 \text{ and } 2\sigma+\mu=85[/tex]
Now we'll write this vertically:
[tex] \left \{ {{-3\sigma+\mu=60} \atop {2\sigma+\mu=85}} \right. [/tex]
We will "eliminate" μ by subtracting the bottom equation:
[tex] \left \{ {{-3\sigma+\mu=60} \atop {-(2\sigma+\mu=85)}} \right. \\ \\-5\sigma=-25[/tex]
Divide both sides by -5:
[tex]\frac{-5\sigma}{-5}=\frac{-25}{-5} \\ \\\sigma=5[/tex]
Our standard deviation is 5. Substituting this into our top equation we have:
-3(5)+μ=60
-15+μ=60
Cancel the -15 by adding it to both sides:
-15+μ+15=60+15
μ=75
Our mean is 75.
Final answer:
By using the z-score formula and solving a system of linear equations, we find that the mean (μ) of the population is 75, and the standard deviation (σ) is 5.
Explanation:
To find the mean (μ) and standard deviation (σ) of the distribution based on the given z-scores, we can use the z-score formula:
z = (X - μ) / σ. Rearranging this formula, we can express X as X = zσ + μ.
For the two provided z-scores and X values:
For X = 60 and z = -3.0: 60 = (-3)σ + μ
For X = 85 and z = 2.0: 85 = (2)σ + μ
We now have a system of linear equations that can be solved to find μ and σ:
-3σ + μ = 60
2σ + μ = 85
Solving for σ and μ:
Multiplying the first equation by 2, and the second equation by 3 and adding them gives us:
(-3)(2)σ + 2μ = 120
(2)(3)σ + 3μ = 255
Adding these together yields 5μ = 375, so μ = 75.
Now, substitute the μ value into either equation to find σ:
-3σ + 75 = 60
σ = (75 - 60) / 3
σ = 5
Therefore, the mean (μ) of the population is 75 and the standard deviation (σ) is 5.

A news reporter wants to estimate the percentage of registered voters who will vote for a particular candidate in an upcoming election. Which statement describes a method that will help him accurately estimate this percentage?
Answer: In order to estimate the percentage of registered voters who will vote for a particular candidate in an upcoming election, a news reporter can randomly take a sample from the registered list of voters and based on their opinion a reporter can accurately estimate percentage of registered voters who will vote for a particular candidate in an upcoming election. Therefore, the option C will be correct.
Therefore the correct method is C) He could take a random sample of registered voters, and then calculate the percentage of the sample who will vote for the particular candidate.
The other options to gather the opinion about the percentage of the sample who will vote for the particular candidate are non probabilistic and there is every possibility of introduction of bias in the estimate. The only option which is probabilistic is option c because it involves random selection of respondents. Therefore the appropriate option is c.

A prism with a volume of 270 m³ is dilated by a factor of 3. What is the volume of the dilated prism? Enter your answer in the box.
If we dilate each dimension by 3, then the volume of the figure will be dilated by [tex] 3^{3} [/tex] .
[tex] 3^{3} [/tex] =3*3*3 =27
So, the volume of the dilated prism is [tex] 3^{3} [/tex] *volume of original prism
Volume of dilated prism=27*270[tex] m^{3} [/tex]
Volume of dilated prism=7290[tex] m^{3} [/tex]
The volume of a prism when dilated by a factor of 3 increases to 7290 m³,
A prism with a volume of 270 m³ that is dilated by a factor of 3 will have its new volume calculated by cubing the scale factor and multiplying it by the original volume.
Original Volume (V1) = 270 m³
Scale Factor (k) = 3
Dilated Volume (V2) = V1 × k³
So, V2 = 270 m³ × 3³
V2 = 270 m³ × 27
V2 = 7290 m³
Hence, the volume of the dilated prism is 7290 m³.

there are 238 juniors at a high school. the ratio of girls to boys in the junior class 3:4. how many Juniors are girls? how many are boys?
Answers
1. Add the numbers in the ratio together:
3 + 4 = 7
2. Divide that number by the quantity given:
238 / 7 =
34
3. Multiply each part of the ratio by the quotient:
4 x 34 = 136
3 x 34 = 102
102 + 136 = 238
4. Answer the problem using the information you just found:
The ratio of girls to boys in the junior class is 102 : 136.
The number of juniors in a class is 238 and the ratio of girls to boys is 3:4. We can use this information to calculate that there are 102 girls and 136 boys in the junior class.
Explanation:The question provides us with the information that there are 238 juniors in the school and the ratio of girls to boys in this class is 3:4. This means for every 7 students (3 girls and 4 boys), there are 3 girls and 4 boys.
First, let's find out how many 'sets' of 7 students there are in the total number of juniors. To do this, we divide 238 by 7, which equals 34 sets.
To find out the number of girls, we multiply these 34 sets by 3 (because the ratio tells us there are 3 girls in each set). This comes to 102 girls.
Similarly, to find out the number of boys, we multiply these 34 sets by 4 (because the ratio tells us there are 4 boys in each set). This gives us 136 boys.
Therefore, in the junior class, there are 102 girls and 136 boys.

t = 5
if

r'(u)du = 0?
Answers
Final answer:
The bee returns to the starting point at (5, -5, -3) after 5 seconds since the integral of its velocity over that period is zero, indicating no net change in position.
Explanation:
To find where the bee is located at time t = 5, we start by looking at the given velocity vector r'(t). Since ∫05r'(u)du = 0, this implies that the integral of the velocity function over the interval from 0 to 5 seconds results in zero net displacement. Thus, the total change in position of the bee over these 5 seconds is zero.
Since the bee starts at the position (5, −5, −3) at t = 0, and there is no net change in position over 5 seconds, the bee must return to the starting point at t = 5. Therefore, the bee is located at (5, −5, −3) at time t = 5 seconds.

C) (58 + 32) x 4= ?
D) (58 - 32) x 4= ?
Answers
Answer:
The right option is (C) (58 + 32)×4
Step-by-step explanation:
Total number of rooms = 4
Number of seats on left = 58 seats in each room
Number of seats on right = 32 seats in each room
Total number of seats in a room = 58 + 32 seats
Total number of seats in the movie theater = Number of rooms × Number of seats in each room
Total number of seats in the movie theater = 4 × (58 + 32) = 360 seats
Hence the right option is (C) (58 + 32)×4

X is less than or equal to -8 graphed on a number line
Answers
x <= - 8
Notice that the inequality solution is
(-inf, -8]
In the graph the parenthesis implies that the value of minus infinity is not included. The bracket implies that the value x = -8 is included in the solution of the inequality.
See attached graph.
Graphing x \<= -8 involves placing a solid circle at -8 on a number line and shading everything to the left to represent all numbers less than or equal to -8.
To graph x \<= -8 on a number line, you need to include every number that is less than or equal to -8. Start with a number line and locate the point -8 on it. Then, draw a solid circle at -8 to indicate that -8 is included in the solution (because of the '<=' symbol). Next, shade or draw a thick line to the left of -8, going towards the negative direction, to cover all numbers that are less than -8. This shaded area represents all the possible values for x that satisfy the inequality x \<= -8.
Visual Representation on Number Line
A visual representation helps to understand the solutions to the inequality. When graphing, remember that the area to the left of the chosen point on a number line includes all numbers less than the indicated value, and if the circle is solid, that point is also part of the solution set.
The process described here provides a straightforward approach to graphing linear inequalities on a number line, which is a fundamental concept in algebra.
