CAN SOMEONE DEVELOPE A STASTICAL QUESTION FOR ME BECAUSE I HAD TO REDO THIS 2 TIMES AND I DONT GET IT

Answers

Answer 1
1. I want to know what percent of the school has birthdays in the summer
2. A form with the months of the year listed, so each participant can just circle the month they were born in. I’d have pencils and a form collection box.
3. I would give the form to every fifth student to leave the cafeteria on one day. I will count up how many forms were completed and how many forms have a summer birth month circled. Then I can find the percentage of students surveyed who have summer birthdays.
————————-

I think what they’re looking for it is for you to get information that reflects a part of a larger group of students.

Statistics always wants a randomized sample, giving everyone an equal chance to be surveyed and/or represented in the survey. Getting the survey done in one day, on people leaving the cafeteria, where everybody has to go at some point in a day, and choosing every fifth person keeps you from showing any bias to who you’re surveying.

Please comment if you have questions about this, or if your teacher asks for more information.

A cone and cylinder each have a height of 10 inches and a radius of 5 inches. If you filled the cone completely with water and poured it into the cylinder. How many times would it take until the cylinder is completely full with water?

Answers

Answer:

The times that would take until the cylinder is completely full with water by the cone are:

3 times.

Step-by-step explanation:

To identify how many times we must fill a cone to fill completely a cylinder with the same height and radius, we must calculate the volume of the two containers and next divide the volume of the cylinder by the volume of the cone. To obtain the volume of the cylinder we can use the next formula:

Volume of a cylinder = [tex]\pi[/tex] * [tex]radius^{2}[/tex] * [tex]height[/tex]

If we replace the values in the formula, we obtain:

Volume of a cylinder = [tex]\pi[/tex] *(5 inches)^2 * 10 inchesVolume of a cylinder = 785.4 inches^3 approximately.

Now, we're gonna calculate the volume of the cone with the next formula:

Volume of a cone = [tex]\frac{\pi*radius^{2}*height }{3}[/tex]

As you can see just with the formula, The volume of a cone is three times less than that of a cylinder (because we add the dividend 3 to it), but we're gonna replace and prove it:

Volume of a cone = [[tex]\pi[/tex] *(5 inches)^2 * 10 inches] / 3Volume of a cone = [785.4 inches^3] / 3Volume of a cone = 261.8 inches^3 approximately.

And, if we divide the two volumes to obtain the times we need to fill the cone to fill completely the cylinder:

Times we need to fill the cone = 785.4 / 261.8Times we need to fill the cone = 3

By this reason, you must fill completely a cone 3 times to fill completely a cylinder with the same radius and height.

A salesperson is paid a base salary of $300 a week plus a 5% commission on the sales he generates. Which inequality best represents s, the amount of sales in dollars he must generate to earn more than $500 for the week? s greater-than 25 s greater-than 200 s greater-than 4,000 s greater-than 16,000

Answers

Step-by-Step:

A salesperson receives a base salary of $300 per week and a commission of 15% on all sales over $5,000. If x represents the salesperson’s weekly sales, express the total weekly earnings E(x) as a function of x and simplify the expression. Then find E(2,000) and E(7,000) and E(10,000).

15% as a decimal is written as 0.15.

Build our weekly earnings function

E(x) = Commission + Base Salary

E(x) = 0.15(Max(0, x - 5000)) + 300

Now find the sales salary for 2,000, 7,000, and 10,000 in sales

E(2,000) = 0.15(Max(0,2000 - 5000)) + 300

E(2,000) = 0.15(Max(0,-3000)) + 300

E(2,000) = 0.15(0) + 300

E(2,000) = 300

E(7,000) = 0.15(Max(0,7000 - 5000)) + 300

E(7,000) = 0.15(Max(0,2000)) + 300

E(7,000) = 0.15(2,000) + 300

E(7,000) = 300 + 300

E(7,000) = 600

E(10,000) = 0.15(Max(0,10000 - 5000)) + 300

E(10,000) = 0.15(Max(0,5000)) + 300

E(10,000) = 0.15(5,000) + 300

E(10,000) = 750+ 300

E(10,000) = 1,050

First rectangle :

Dimension = 40 yards by 20 yards

Area = 40 * 20 = 800 yd²

Rectangule 2 :

if a and b are roots of 3x2-6+2=0then find a+b​

Answers

Answer:

a + b =  2

Step-by-step explanation:

Given

ax² + bx + c = 0 ( equation in standard form )

Then the sum of the roots = - [tex]\frac{b}{a}[/tex]

3x² - 6x + 2 = 0 ← is in standard form

with a = 3, b = - 6 , then

sum of roots = - [tex]\frac{-6}{3}[/tex] = 2

Answer:

[tex]I \ think \ it \ is \ 6x\\\\3x^2 - 6x +2 = 0\\\\[/tex]

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2a} \\\\a = 3, b = -6, c = 2\\\\x = \frac{-b + \sqrt{b^2 - 4*a*c} }{2a}, x = \frac{-b - \sqrt{b^2 - 4*a*c} }{2a} \\\\ \\\\x = \frac{6 + \sqrt{36 - 24} }{6} , x = \frac{6-\sqrt{36 -24} }{6} \\\\[/tex]

[tex]x = \frac{6+\sqrt{12} }{6} , x = \frac{6-\sqrt{12} }{6} \\\\x = \frac{3+\sqrt{3} }{3} , x = \frac{3-\sqrt{3} }{3}[/tex]

[tex]Let \ a = \frac{3 + \sqrt{3} }{3} , b = \frac{3-\sqrt{3} }{3} \\\\a + b = \frac{3+\sqrt{3} }{3} + \frac{3-\sqrt{3} }{3} = \frac{3+\sqrt{3} +3-\sqrt{3} }{3} = \frac{6}{3} = 2[/tex]

Use the box method to distribute and simplify (−6x^3-x^2 -6x+2)(6x-2). Drag and drop the terms to the correct locations of the table.

- 6x³           - 36x⁴          12x³

  - x²           - 6x³           2x²

- 6x           - 36x²         12x

   2              12x           - 4

What is Distributive property?

By the rule of distributive property, multiplying the sum of two or more addends by a number gives the same result as when each addend is multiplied individually by the number and the products are added together.

Given that;

The expression is;

⇒ (−6x³ - x² - 6x + 2) (6x - 2)

Now,

Solve the expression as;

⇒ (−6x³ - x² - 6x + 2) (6x - 2)

After multiplying, we get;

⇒ - 36x⁴ + 12x³ - 6x³ + 2x² - 36x² + 12x + 12x - 4

Thus, The complete table is,

                   6x            - 2

- 6x³           - 36x⁴          12x³

  - x²           - 6x³           2x²

Now, add the numbers to get 0 & multiple together to get -64

 -64 = 8 x -8

 8 + -8 = 0

Find the volume of the composite solid.

Answers

Answer:

156 ft³

Step-by-step explanation:

Volume of the composite solid = volume of the square prism + volume of the square pyramid

✔️Volume of rectangular prism = a²h

a = 6 ft

h = 3 ft

Volume = 6²*3 = 36*3

Volume = 108 ft³

✔️Volume of square pyramid = ⅓(a²*h)

a = 6 ft

h = 4 ft

Volume = ⅓(6²*4) = ⅓(36*4)

Volume = 48 ft³

✅Volume of the composite solid = 108 + 48 = 156 ft³

Alright, to start, slope-intercept form is y=mx+b, where m is the rate is it going up/down by, and b is the starting point.

With this, the question says that Coraz started with 0 naxvips then purchased 10 each month afterwards.

From this, we can fill in the equation, using m as the rate it is going up/down and b as the starting point:

The Equation:

y=10x+0

Next, it wants a table, so let's use the equation created to do this. X is the amount of months that have gone by, deciding how many naxvips Coraz has purchased.

So, to start, lets plug in 0 months into the equation into x:

y=10(0)+0

y=0+0

y=0

The answer resulted in 0 for month 0, understandably. Month 0 was when it said Coraz had 0 naxvips on his farms. With this, it would be (0,0) for this part.

For the next month, same thing, just plug it in:

y=10(1)+0

y=10+0

y=10

The answer resulted in 10 for month 1. Month 1 was when it said Coraz purchased his first batch of 10 naxvips. With this, it would be (1,10) for this part.

Again, with 2 months

y=10(2)+0

y=10+0

y=20

The answer resulted in 20 for month 2. Month 2 was when he got another 10 naxvips. With this, it would be (2,10) for this part. However, see the pattern? For every month, there will be 10 more naxvips added. With this, we can write out the table for it as well:

The Table:

(X, Y)

0, 0

1, 10

2, 20

3, 30

4, 40

Answer:

Step-by-step explanation:

the standard equation is

(x-h)²+(y-k)²=r²

where (h, k) is the center in our case ( -5, -5) and r is the radius that in our case r=2, so substitute

(x+5)²+(y+5)²=2²

Answer:

[tex](x+5)^2+(y+5)^2=4[/tex]

Step-by-step explanation:

Hi there!

Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius

1) Determine the center of the circle

On the graph, we can determine that the circle is centered at the point (-5,-5). Plug this into the equation:

[tex](x-(-5))^2+(y-(-5))^2=r^2\\(x+5)^2+(y+5)^2=r^2[/tex]

2) Determine the value of r²

In the graph, we can see that the radius of the circle is equal to 2 units. Therefore, the value of r² is 4. Plug this back into the equation:

[tex](x+5)^2+(y+5)^2=4[/tex]

 Grapes Rs 120.60

 Apples Rs 78.40
