Answer:
Mean of 64 and standard error of 0.9.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Phone bills from the residents of the city have a mean of $64 and a standard deviation of $9. Sample of 10.
By the Central Limit Theorem, the mean is 64 and the standard error is [tex]s = \frac{9}{\sqrt{100}} = \frac{9}{10} = 0.9[/tex]
So mean of 64 and standard error of 0.9.

What triangle is formed by the points (3,2), (4,7), and (5,6)?
Answer:
Scalene Triangle
Step.-by-step explanation:
Calculate the lengths of the sides:
Side 1 = √((4-3)^2+(7-2)^2) = √26.
Side 2 = √((6-7)^2+(5-4)^2) = √2.
Side 3 = √((6-2)^2+(5-3)^2) = √20.
So each side is different in length and so its a scalene triangle.
Ethan has a spinner that is divided into 5 equal-size sections colored red, blue, orange, white, and green. What is the probability that Ethan spins pink on the next spin?
Answer:
0
Step-by-step explanation:
Pink isn't on the spinner, and so he doesn't have any chance of spinning it.
Answer:
00%
Step-by-step explanation:
There is no color pink in one of the sections, meaning there is zero probability it will land on pink.

Answer:
X = 10.7
Step-by-step explanation:
25^2 - 16^2 = 369 which squared is approximately 19.2. We need X which is the smaller side so we minus 22^2 from 19.2^2 which is 115.36 which is squared to 10.7

does anyone know a edulastic hack?
Answer: The Pacing Method:
Use Edulastic to help convey weekly expectations and track student progress along the way
You can set up Edulastic to function as your check-in-tool with students, and Edulastic will help you in gathering student data during this process (#Edulasticforthewin!). This can help in estimating student participation grades and preparing reports to supervisors. It can also help with pacing and students staying on task.
When I was a high school science teacher I would structure “Check ins” with my students on written handouts that students had to present to me for my signature (upon meeting and discussing project updates, hearing feedback from me etc.). If I had access to Edulastic tools then, I could have instead coordinated these check ins digitally and privately using Edulastic. They could check-in on their own time, at home or at school. That makes things a heck of a lot more efficient than having students form a line waiting to talk to me at my desk! You can set this up to occur at the every other day mark, weekly mark, biweekly, or even monthly mark depending upon length and scope of a project in place.
Check out how this might look in Edulastic:

From a piece of paper, Sam cuts a rectangle with a length that is 2 inches (in.) longer than the width. He tapes a straw to the long side of the rectangle. Holding the straw horizontally at one end, he twirls it, causing the rectangle to create the image of a solid figure. Which statement best describes the solid figure?
a) A rectangular prism with a volume of w^{2\ }+\ 4w\ \ +4\ in^3w 2 +4w+4in 3 where w represents the width of the rectangle.
b) A rectangular prism with a volume of w^3+4w^{2\ }+4w\ in^3 w 3 +4w 2 +4win 3 where w represents the width of the rectangle.
c) A cylinder with a volume of \pi\left(w^3+2w^2\right)in^3π(w 3+2w 2)in 3 where w represents the width of the cylinder.
d) A cylinder with a volume of \frac{\pi\left(w^3+2w^2\right)}{3}in^33π(w 3+2w 2 ) in 3 where w represents the width of the cylinder.
Answer:
c)A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
Step-by-step explanation:
A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
The volume of a cylinder is given by V=Bh or V=πr²h
where B is the area of the base and h is the height of the cylinder.
V=πr²h-------equation1
V= π(w³ +2w² )--------- equation2
Comparing equation 1 and equation 2
πr²h=π(w³ +2w² )
r²h=(w³ +2w² )
r²h= w²(w +2 )
Taking w² common leaves w+2 which gives the height or length of the cylinder.
Therefore radius = width and height = length which gives the volume of the cylinder.

#4: 130/60, simplified is 13/6 (divide numerator and denominator by 10)
#5: 110/130, simplified is 11/13 (divide numerator and denominator by 10)
#6: 5/12
#7: 4/12, simplified is 1/3 (divide numerator and denominator by 4)
#8: 12/4, simplified is 3, or 3/1 (divide numerator and denominator by 4)
Step-by-step explanation:
#4: Part 1 is 60 miles, and the whole trip is 60 + 20 + 50 = 130 miles
So while #1 was 60 over 130 for "60 to 130", now we'll put the 130 on top of the 60 for "130 to 60" as a spoken ratio
#5: I think they mean add part 1 to part 3, then compare to the whole.
so 60 + 50 = 110, and your answer is 110/130

PLEASE HELP ME WITH THIS
Answer:
A. (0, 60)
B. 15x
Step-by-step explanation:
The initial value is the same as the y-intercept, which is 60 or (0, 60).
The rate of change would be the same as the slope. To find the slope, you do rise/run. You move 15 units up, and 1 to the right. That would be 15x.

Using the tangent ratio, the value of x, to the nearest tenth, is: 5.5.
How to Use the Tangent Ratio to Solve a Triangle?Given a right triangle with a missing length, x, we have the following:
∅ = 70°
Opposite side length = 15
Adjacent side length = x
The tangent ratio to be applied is:
Tan ∅ = opp/adj
Plug in the values
Tan 70 = 15/x
x(tan 70) = 15
x = 15/tan 70
x ≈ 5.5

HELP PLEASE! (SLOPE INTERSCEPT QUESTION)
SHOW HOW PLEASE!
Answer:
y = 4x +2
Step-by-step explanation:
The formula/equation for slope-intercept form is: y=mx+b. M stands for slope and b stands for the y-intercept.
In this question, you're already given the slope, 4, so luckily, you don't need to find that. However, you need to find the y-intercept, or otherwise known as b in the slope-intercept formula.
Given coordinates: (6, 26) ---> (6 is the x-intercept, and 26 is the y-intercept)
Slope: 4
Plug those values into y=mx+b
26 = 4(6) + b
26 = 24 + b
Subtract 24 on both sides to isolate out b.
2 = b
Now that you've found the y-intercept, plug in your stuff to form your slope-intercept equation/formula.
y = 4x + 2

The question is illustrated with the attached image
Required
Find [tex]\theta[/tex]
To do this, we use sine formula
i.e.
[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]
So, we have:
[tex]\sin(\theta) = \frac{10.8}{16.6}[/tex]
[tex]\sin(\theta) = 0.6506[/tex]
Take arc sin
[tex]\theta = \sin^{-1}(0.6506)[/tex]
