1.Were your two estimates the same? Did the mean length of all the straws in the bag change in between selecting the two samples? Explain your reasoning.

2.The actual mean length of all of the straws in the bag is about 2.37 inches. How do your estimates compare to this mean length?

3.If you repeated the same process again but you selected a larger sample (such as 10 or 20 straws, instead of just 5), would your estimate be more accurate? Explain your reasoning.





Remember that sample 1 mean= 4


Sample 2 mean = 3.8

Answer: 39°, 72°, 45°, 150°

Step-by-step explanation:

A circle has 360 degrees. [tex]\frac{1}{360}[/tex] would be equal to 1°

1) [tex]\frac{39}{360}[/tex] would be equal to 39° based on the rule above ^^

2) This fraction has a denominator of 5. Turn the denominator into 360. We can do this by multiplying the bottom by 72, since 360 ÷ 5 = 72 (make sure to multiply the numerator by 72 as well!)

[tex]\frac{1*72}{5*72}[/tex] = [tex]\frac{72}{360}[/tex]

This is equal to 72°

3) Use the same method as before

[tex]\frac{1*45}{8*45}[/tex] = [tex]\frac{45}{360}[/tex]

This is equal to 45°

4) Use the same method as before

[tex]\frac{5*30}{12*30}[/tex] = [tex]\frac{150}{360}[/tex]

This is equal to 150°

Answer: 96

Step-by-step explanation: the formula to finding the volume of a rectangular prism is width x length x height. after plugging our values in, we have 2 x 6 x 8, which is equal to 96

Answer: D

Step-by-step explanation:

$9 for each ball she buys, s, and the added shipping cost

Answer:

The correct answer is D

Step-by-step explanation:

EACH BALL COSTS $9

The number of balls they are going to buy is s.

They will cost 9s, but we get extra 10 to pay... so its 9s + 10

Answer:

32 pints

Step-by-step explanation:

Given :-

And we need to find how many pints of red paint will we use .So let us take that we used x pints.

According to the Question :-

[tex]:\implies[/tex] 4:3 = x : 24

[tex]:\implies[/tex] 4/3 = x/24

[tex]:\implies[/tex] 4 = x/8

[tex]:\implies[/tex] x = 8*4

[tex]:\implies[/tex] x = 32

Hence we will use 32 pints of red paint.

Answer:

probably 32.

Step-by-step explanation:

4x8= 32

3x8= 24

Answer:

Step-by-step explanation:

a) Let the cost of a Pizza = $ x

Cost of three pizza's = 3 *x = 3x

cost of 3 pizza + cost of a salad = $ 20.7

3x + 3 = 20.7

b) 3x + 3 = 20. 7     {Subtract 3 from both sides}

3x       = 20.7 - 3

     3x = 17.7  {Divide both sides by 3}

       x = 17.7/3

      x  = 5.9

Cost of one pizza = $ 5.9

Answer:

4) 724

5) 750

6) 390

Step-by-step explanation:

[tex]SA_1 = 2(lw + lh + wh) = 2(17 * 14 + 17 * 4 + 14 * 4) = 2(238 + 68 + 56) = 2 * 362 = 724[/tex]

[tex]SA_2 = 2(lw + lh + wh) = 2(19 * 13 + 19 * 4 + 13 * 4) = 2(247 + 76 + 52) = 2 * 375 = 750[/tex]

[tex]SA_3 = 2(lw + lh + wh) = 2(14 * 9 + 14 * 3 + 9 * 3) = 2(126 + 42 + 27) = 2 * 195 = 390[/tex]

Answer:

n+11

Step-by-step explanation:

Answer:

1. m > 6

2. t > 16/5

3. x < 26.75

4. n < 49.2

Answer:

m > 6

t > 16/5

x < 26.75

n < 49.2

Step-by-step explanation:

84<14m

84-(14*m) < 0     Set to zero

84 - 14m   =  -14 • (m - 6)      

m-84/-14 ( isolate 14 by - 14 both side)

ie) m -84/-14  = m 84/-14

m > -84/-14    (then divide -84  by -14)

m> 6

55t > 176

55t  / 55 >176/55   (working left to right divide both sides by 55)

t > 16/5

x + 22.5 < 49.25  

x+22.5−22.5<49.25−22.5     (working left to right -22.5 each side.)

x < 26.75

37.2>n−12  

n−12<37.2               ( by flipping equation)  

n−12+12<37.2+12    ( working left to right + 12 to both sides)

n<49.2

Given :-

Given :- Emilia pays $24 to rent a boat at the lake for up to 6 hours. She constructs the inequality and number line below to represent the number of hours .

Answer:

→ Emilia inequality for x number of hours = x ≤ 6 .

since, she pays $24 for upto 6 hours , she can use boat from 0 hours to maximum 6 hours .

therefore, Emilia's inequality x ≤ 6 is correct because the number of hours is less than or equal to 6 .

now, from image, we can see that, Emilia uses number line from 0 hours to 14 hours in number line .

But correct number should be from 0 hours to 1,2,3,4,5 and 6 hours only .

therefore, Emilia's number line is incorrect . The endpoint is filled in and the number line is greater than the endpoint.

Step-by-step explanation:

Answer: emilias inequality x<6 is correct because the number of hours is less than or equal to six. emilias Number line is correct. the endpoint is correctly filled in and the number line should be shaded to the left of the endpoint.

Answer:

Seth hikes 3.5 mph along the x-axis. David hikes 2.5 mph along the y-axis.

So the ordered pairs will be in the form

(3.5x, 2.5x), where x = number of hours.

Here are the correct ordered pairs:

(0, 0), (7, 5), (21, 15)
