Answer:

The value of given expression is -22.

Step-by-step explanation:

We are given attached graph with the question.

The graph consist of plot for two function y = f(x) and y= g(x).

We need to evaluate the value of expression:

-3\times f(-8) + 7\times g(2)

From the given graph, it is easy to calculate value for f(-8) and g(2).

From graph:

f(-8) = -2

g(2) = -4

These values were obtained by looking the corresponding y-value for given x-values from the graph.

Putting the values in the expression, we get:

(-3)\times (-2) + 7\times (-4) = 6 - 28 = -22

Hence, the value of given expression is -22.

Answer:

-22

Step-by-step explanation:

-3•f(-8)+7•g(2)=

The value of f(x) at x=-8 is

f(-8) = -2

The value of g(x) at x=2 is

g(2) = -4

Substituting these values into the equations

-3 * -2 +7*-4

6 -28

-22

Lo siento, no hago matemáticas por favor hazlo tú mismo. En caso de que no traduzcas esto voy a poner un par de números. 34 es el número para hacer que alguien que habla inglés esto es legítimo. 45 = 28 + x28. Te quiero

Three friends, Ana, Jack and Nick come together to purchase a special from a pizza place. It is a half pepperoni, half mushrooms
maw [93]

Answer:

Paula would choose the side with all of the mushrooms and half of the pepperoni. She wont choose any sausage because she doesn't like it, but luckily David likes sausage twice as much as mushroom so he's fine with getting all of the sausage and half of the pepperoni. They both equally like pepperoni so it makes sense for them to share.

Using a sample of 60 undergraduates, Dr. Hotchkins discovers a negative correlation between stress and emotional well-being. Whi
svet-max [94.6K]

Answer and explanation:

A negative correlation means a relationship between two variables whereby each variable affects the other such that an increase in one variable means a decrease in the other and vice versa. This is the situation with the correlation graph/scatter plot of Dr. Hotchkins: An increase in stress would cause a decrease in emotional well being and vice versa

An Outlier is a data point on the scatter plot that does not fall into the pattern of the correlation graph. From the above, 4 points are outliers: extremely high points on stress and emotional well being. These points would affect (increase or decrease) the correlation coefficient depending on where they fall in the pattern. In this case there are 4 outliers out of 60 data points and we know that the more outliers there are the more effect they have on the correlation coefficient and vice versa(also depending on where the outlier is on the scatter plot)
