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.

Answer:

0.6

Step-by-step explanation:

We know that there are 5 counters in total. 3 white and 2 black.

So we know that 3 out of 5 are white and 2 out of 5 are black.

Therefore the chance to get white is 3/5. And for black: 2/5.

We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)

And 2/5 = 0.4 (You can make it 4/10 to make it easier.)

Answering the question, you should put your cross/marker on 0.6

A puddle originally contained 2.5 gallons of water. After a hot day, only 1 gallon of water remains.

What is the percent decrease?

Enter your answer in the box.

%

Answers

Answer:

60%

Step-by-step explanation:

There is a 60% decrease because 60% of 2.5 = 1.5

So, 2.5 - 1.5 = 1.

Or

1.5/2.5 = 0.60 (which is 60% as a percentage)

Step-by-step explanation:

well if you take 35x, which is 35 times whatever, + 70, you get y. so the first one is 35(1) + 70 = 105.

so i’ll go in order

35 x 1 + 70 = 105

35 x 2 + 70 = 140

35 x 3 + 70 = 175

35 x 4 + 70 = 210.

just multiply then add 70

hope this helped

Answers

Answer:

D, A, A, B, C

Step-by-step explanation:

1.

P(odd) = 3/6 = 1/2

P(blue) = 1/5

P(odd and blue) = 1/2*1/5 = 1/10

2.

Possible outcomes are 9 as all non-zero digits. And 8 is one of them.

P(8) = 1/9

3.

Non-zero digits: 1, 2, 3, 4, 5, 6, 7, 8, 9

5 of them are odd and 4 of them are even.

One digit is discounted as can't repeat and 4 out of remaining 8 are even.

P(even) = 4/8 = 1/2

4.

Remaining marbles: 2 orange, 3 black, 4 pink. Total 9

P(pink) = 4/9

5.

Each spinner has 3 colors.

P(red or orange) = 2/3

P(both red or orange) = 2/3*2/3 = 4/9

Step-by-step explanation:

The rate of change (which is basically the slope) can be found by dividing the rise/run or the distance up and sideways from a point on a line to another point.

If we go from the first point (0, -4) to the next point on the line (1, -1), we would go up 3 spaces and right one space. 3/1 which would be 3
