3/7 because if u do the cross cancel, 6 divided by 2 u get 3 so it’d be 3/7 x 1/1 equals to 3/7

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.

If Starbucks’s marketing department estimates the income elasticity of demand for its coffee to be 2.8, how will the prospect of

cluponka [151]

Answer:

The percent change in quantity is -0.14%.

Step-by-step explanation:

The formula to compute the change in quantity is:

$Income\ elasticity\ of\ demand=\frac{Percent\ change\ in\ qunatity\ demanded}{Percent\ change\ in\ price}$

The income elasticity of demand is 2.80.

Percent change in price is -5% (since the prices decreases)

Compute the percent change in quantity demanded as follows:

$Income\ elasticity\ of\ demand=\frac{Percent\ change\ in\ qunatity\ demanded}{Percent\ change\ in\ price}\\2.80=\frac{Percent\ change\ in\ qunatity\ demanded}{-5\%}\\Percent\ change\ in\ qunatity\ demanded=2.80\times(-5\%)\\=-0.14\%$

Thus, the percent change in quantity is -0.14%.

Which ordered pair (x, y) satisfies the system of equations shown below?

Dima020 [189]

Answer: (7, 0)

Step-by-step explanation:

We have the system of equations:

9*x - y = 63

x = y + 7

We can see that the "x" is isolated in the second equation, then we can replace it in the first equation to get:

9*x - y = 63

9*(y + 7) - y = 63

Now we have an equation that only depends on one variable, so we can solve it:

9*y + 63 - y = 63

8*y + 63 = 63

8*y = 63 - 63 = 0

y = 0/8 = 0.

Now we know the value of y, we can replace this in one of the initial equations to find the value of x, i will replace this in the second equation:

x = y + 7 = 0 + 7 = 7

Then the point that is a solution for the system of equations is (7, 0)
