Which option identifies which of the two studies described has the more reliable data set and explains why?

Study 1: A survey was conducted 10 times, and the standard deviation was 7.8 percent of the mean.

Study 2: A survey was conducted 100 times, and the standard deviation was 14.5 percent of the mean.

Because the data distribution is more spread out as standard deviation increases, study 1 is more reliable.
Because the margin of error increases as sample size increases, study 1 is more reliable.
Because the data distribution is less spread out as standard deviation increases, study 2 is more reliable.
Because the margin of error decreases as sample size increases, study 2 is more reliable.

Ben drinks tea at an incredible rate. He drinks 7/2 liters of tea every ⅔ of an hour. How many liters of tea did he drink in one hour. Show your work.

Answers

Answer:

[tex]\frac{21}{4}[/tex] or 5.25 litres

Step-by-step explanation:

Hi there,

Since 1 hour is equivalent to [tex]\frac{3}{3}[/tex] and we have the amount for [tex]\frac{2}{3}[/tex] of an hour, we can find the amount Ben drinks for [tex]\frac{1}{3}[/tex] hour and multiply by 3.

To find the amount Ben drinks in [tex]\frac{1}{3}[/tex] hour, we should divide the amount at [tex]\frac{2}{3}[/tex] hour by 2.

[tex]\frac{7}{2}[/tex] ÷ 2 = [tex]\frac{7}{4}[/tex]

Now that we know the amount at [tex]\frac{1}{3}[/tex] hour, we can multiply by 3 to determine the amount of tea he drank in one hour.

[tex]\frac{7}{4}[/tex] × 3 = [tex]\frac{21}{4}[/tex]

Therefore, Ben drank [tex]\frac{21}{4}[/tex] or 5.25 litres of tea in one hour.

Hope this answer helps. Feel free to ask questions.

23.7 – y ____ y = 10

Answers

Answer:

23.7 - 10 = 13.7

Step-by-step explanation:

Question

23.7 - Y (____)   Y = 10

                                                                                                                                     

Answer

So the starting number is 23.7 if Y = 10 and we have to subtract the answer would be (13.7)

Hence, all that information all we had to do was subtract 23.7 - 10 = 13.7

Answers

X=12

Dkdndiekodrn rjrjrnrirnr

Answer:

x=12

Step-by-step explanation:

start with this equation:

26-x=14

it's best to make the x variable positive at all times.

to do that, you need to make everything else positive.

-26+x=-14

then add 26 to both sides.

x=-14+26

which basically says 26-14...

x=12

Write an equation to represent the amount of water in the bucket, y, in terms of the number of minutes, x, since the faucet was turned on

Answers

Answer:

y= 3x+125

Step-by-step explanation:

y intercept is 125

gradient is 3

y=Mx+c

y=3x+125

Answer:

y = 75x + 125

Step-by-step explanation:

Write in form y = mx + b

75 is the slope (m)

125 is the y-intercept (b)

So the equation would be y = 75x + 125.

BTW, the slope is written in rise/run form. For this graph, it is 75/1.

Which fraction is less than the fraction represented by the model? A circle divided into 8 equal parts. 5 parts are shaded. Three-fourths Start Fraction 11 Over 16 End Fraction Start Fraction 13 Over 16 End Fraction Start Fraction 2 Over 4 End Fraction

Answers

Answer:

Step-by-step explanation:

The fraction represented by the model is 5/8. To compare it with the given fractions, we need to convert them to have the same denominator of 8.

- Start Fraction 11 Over 16 End Fraction = 11/16 = 0.6875

- Start Fraction 13 Over 16 End Fraction = 13/16 = 0.8125

- Start Fraction 2 Over 4 End Fraction = 2/4 = 1/2 = 0.5

To compare these fractions to 5/8, we can see that 0.5 is less than 0.625 (which is 5/8), so Start Fraction 2 Over 4 End Fraction is less than the fraction represented by the model. Therefore, the answer is Start Fraction 2 Over 4 End Fraction.
