If there is no relationship (linear or otherwise) between two quantitative variables as observed on a scatterplot, the value of

Ainat [17]

Answer:

Option 3) Closer to 0

Step-by-step explanation:

Correlation:

Correlation is a technique that help us to find or define a relationship between two variables.

A positive correlation means that an increase in one quantity leads to an increase in another quantity

A negative correlation means with increase in one quantity the other quantity decreases.
Range of Correlation

Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.

Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.

A value of 0 tells that there is no correlation between the two variables.

Thus, for the given situation, if there is no relationship between two quantitative variables then the value of the correlation coefficient, r, is close to 0

The table shows transactions in a checking account

Yuki888 [10]

Answer:

i) number of transactions for the month of January = 4

number of transactions for the month of February = 4

number of transactions for the month of March = 4

number of transactions for the month of April = 4

ii) Mean of four months = -495.7 /4 = -123.93

Step-by-step explanation:

i) number of transactions for the month of January = 4

number of transactions for the month of February = 4

number of transactions for the month of March = 4

number of transactions for the month of April = 4

ii) January February March April

-38.50 250.00 -14.00 -86.80

126.30 -135.20 99.00 -570.00

429.40 35.50 -82.70 100.00

-265.00 -62.30 -1.50 -280.10

Total 252.20 88.20 0.80 -836.9

Total of four months = 252.2 + 88.20 + 0.80 - 836.9 = -495.7

Mean of four months = -495.7 /4 = -123.93

A 3 ounce serving of tuna provides 21 grams of protein. Use equivalent ratios to find how many grams of protein are in 9 ounces

denis-greek [22]

Answer:

There would be 63 grams of protein in 9 ounces of tuna.

Step-by-step explanation:

Equivalent ratios compare two different quantities the have the same rate regardless of the amount. In this example, for every 3 ounces of tuna, there are 21 grams of protein. We can write this as a ratio of: 3/21. Like fractions, we can simplify ratios by dividing the numerator and denominator by the same greatest common factor. In this case, we would divide both the numerator and denominator by 3: (3÷3)/(21÷3) = 1/7. So, our new ratio is for every ounce of tuna, we have 7 grams of protein. Using equivalent ratios, we can set up our ratios to solve for the grams of protein in 9 ounces of tuna: 1/7 = 9/x. Since we have to multiply both the numerator and denominator by the same factor, in this case 9, then our x = 63 grams of protein.
