If the correlation coefficient is .87, is its relationship considered to be strong positive,weak positive,strong negative,weak n

myrzilka [38]

Answer:

strong positive correlation co efficient

Step-by-step explanation:

correlation:-

A correlation co-efficient is a numerical measure of some type of correlation,meaning a statistical relationship between two variables.

positive correlation:-

Positive correlation occurs when an increase in one variable increases the value in another.

Negative correlation:-

negative correlation occurs when an increase in one variable decreases the value of another.

Strong positive correlation:-

A co-efficient of correlation of + 0.87 indicates a strong positive correlation between the independent variables

Strong negative correlation:-

A co-efficient of correlation of - 0.87 indicates a strong negative correlation between the independent variables.

Zero correlation:-

There is no relationship is called zero correlation

weak positive correlation:-

A co-efficient of correlation below 0.2 indicates a weak positive correlation between the independent variables.

weak negative correlation:-

A co-efficient of correlation below -0.2 indicates a weak negative correlation between the independent variables.

What is 14.853 oz rounded to the nearest ounce?

Nookie1986 [14]

Answer:

15 oz.

Step-by-step explanation:

Rounding to the nearest ounce:

14.853

Rounding notes:

If the number one place to the right of the rounding number is greater than 5, the number increases by 1.

If the number one place to the right of the rounding number is less than 5, the number stays the same and anything to the right of the rounding number changes to 0.

Work:

4 represents the 'ounces' place value.

To identify the rounding of 4, we need to determine if the value 8 is greater than 5, or less than 5.

8 > 5, meaning 4 increases to 5.

New rounded number = 15 oz.

Jason hires groundskeepers. They work an average of 60 hours per month. If seven groundskeepers are hired at $12/hour, what is t

Kamila [148]

Multiply the cost per hour by 60 to find the cost for a groundskeeper
cost = 12 × 60
cost = 720
The cost for each groundskeeper is $720

Find the cost for seven groundkeepers
Multiply cost for each groundskeeper by 7
cost = 720 × 7
cost = 5,040

The monthly labor cost for seven groundskeepers is $5,040
