An education researcher is interested in comparing the learning outcomes of students who are taught a lesson using five different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researcher will randomly place the students into five equally sized treatment groups suitable for comparison.

Which number range would be needed to label the students correctly?

A 0–4
B 1–5
C 00–75
D 01–75

Answer:

Time with 4.2MB/S speed = 7314.3 seconds

Time with 900 KB/S speed = 34952.5 seconds

Step-by-step explanation:

Given that:

Internet download speed = 4.2 MB/S

File to download = 30 GB

1 GB = 1024 MB

30 GB = 30*1024 = 30720 MBS

Time required = [tex]\frac{30720}{4.2}[/tex]

Time required = 7314.3 seconds

With 900 KB/S

1 MB = 1024 KB

30720 MB = 30720 * 1024 = 31457280 KBS

Time = [tex]\frac{31457280}{900}=34952.5\ seconds[/tex]

Hence,

Time with 4.2MB/S speed = 7314.3 seconds

Time with 900 KB/S speed = 34952.5 seconds

Answer:

Time with 4.2MB/S speed = 7314.3 seconds

Time with 900 KB/S speed = 34952.5 seconds

Step-by-step explanation:

Given that:

Internet download speed = 4.2 MB/S

File to download = 30 GB

1 GB = 1024 MB

30 GB = 30*1024 = 30720 MBS

Time required =

Time required = 7314.3 seconds

With 900 KB/S

1 MB = 1024 KB

30720 MB = 30720 * 1024 = 31457280 KBS

Time =

Hence,

Time with 4.2MB/S speed = 7314.3 seconds

Time with 900 KB/S speed = 34952.5 seconds

[tex]LM = 20[/tex]

Step-by-step explanation:

Given

[tex]LN = 23[/tex]

[tex]MN = 3[/tex]

Required

Find LM

Because M is between L and N, then

[tex]LN = LM + MN[/tex]

Substitute values for LN and MN

[tex]23 = LM + 3[/tex]

90/4=22.5

Ian - 1 mile in 22.5 minutes

2x60=120

60/2=30

120+30=150

150/7=21.43

Bob - 1 mile in 21.43

Answer:

They are not the same because Ian - 1 mile in 22.5 minutes and Bob - 1 mile in 21.43

[tex] \boxed{ \boxed{ \tt{ \: 4. \: \: \: \: \: \: \: \underline{13 \sqrt{3} \: cm}}}}[/tex]

Step-by-step explanation:

First , A simple way how to remind the three basic trigonometric functions is by reminding the famous word " SOHCAHTOA". We divide the word in three words with three letters.

[tex] \underline{ \underline{ \sf{SOH , \: CAH , \: TOA}}}[/tex] :

We write :

Now , Let's work on it :

3. Based on the figure ( 3 ) , we know the hypotenuse ( i.e 15 ) & the angle 53° & we have to find the opposite ( x ).

[tex] \sf{ \sin(53) = \frac{opposite}{hypotenuse} }[/tex]

⇾ [tex] \sf{0.79 = \frac{x}{15}} [/tex]

⇾ [tex] \sf{x = 11.85}[/tex]

----------------------------------------------------------------

5. Based on the figure ( 4 ) , we know the adjacent ( i.e 13 cm & the angle 60° & we have to find the opposite ( x ).

[tex] \sf{ \tan(60}) = \frac{opposite}{adjacent} [/tex]

⇾ [tex] \sf{ \sqrt{3} = \frac{x}{13} }[/tex]

⇾ [tex] \sf{x = 13 \sqrt{3}} [/tex] cm

And we're done !

Hope I helped ! ツ

Have a wonderful day / night ! ♡

The small medium from in center to all the three sides of triangle is equal.

The length of the SQ is 5 units.

The in-center of a triangle is the point of intersection of all the three interior angle bisectors of a triangle.

The small medium from in center to all the three sides of triangle is equal. Thus,

[tex]SQ=SP=SR[/tex]

Given information-

The length of MR is 12 units.

The length of MS is 13 units.

In the [tex]\Delta MRS, \angle MRS[/tex] is the right angle triangle. Thus by the Pythagoras theorem,

[tex]MS^2=MR^2+RS^2[/tex]

Rewrite the equation as,

[tex]RS^2=MS^2-MR^2[/tex]

Put the  values,

[tex]RS^2=13^2-12^2\\RS^2=169+144\\RS^2=25\\RS=\sqrt{25}\\RS=5\\[/tex]

Thus the length of RS is 5 units. As the length of RS is equal tot he length of the SQ. Thus,

[tex]SQ=RS=5[/tex]

Hence the length of the SQ is 5 units.

Answer:

540 m^3

Step-by-step explanation:

We will use the formula V = Bh where B is the base and h is the height. To find the base, we will multiply the length times the width .

18 m * 5 m = 90 m^2

Them, we will multiply the height.

90m^2 * 6 m = 540 m^3

Distance between the two points

AB = √52 = 7.2111

Step-by-step explanation:

Explanation:-

Given points are (-1,-2) and (5,2)

Distance formula

                 [tex]= \sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1})^{2} }[/tex]

                [tex]= \sqrt{(5-(-1) )^{2} +(2 -(-2))^{2} }[/tex]

               [tex]= \sqrt{(6 )^{2} +(4)^{2} }[/tex]

              =   √36+16

             =√52

            = 7.2111

Final answer:-

Distance between the two points

AB = √52 = 7.2111
