lorasvet [3.4K]

Answer:

b= -4.68

Step-by-step explanation:

Hello!

We have to study variables:

Y: Monthly coffe sales

X: Price per pound of coffe ($)

The estimate regression line is

^Yi= a + bxi ∀ (i=1,.....,10)

The slope of the estimated regression line is represented by b.

The formula I'll use to calculate it is:

b= [n∑xiyi -(∑xi)*(∑yi)]/ n∑xi²-(∑xi)²

To calculate b we need to do some auxiliary calculations:

∑xiyi= 4213.15

∑xi= 87.47

∑yi= 545

∑xi²= 883.3703

Then we replace the formula:

b= [10*4213.15-(87.47)*(545)]/ n883.3703-(87.47)²

b= -4.68

I hope you have a SUPER day!

According to Masterfoods, the company that manufactures M&M's, 12% of peanut M&M's are brown, 15% are yellow, 12% are re

algol13

Answer:

0.77 or 77%

Step-by-step explanation:

Given:

Percentage of brown peanuts = 12%

Percentage of yellow peanuts = 15%

Percentage of red peanuts = 12%

Percentage of blue peanuts = 23%

Percentage of orange peanuts = 23%

Percentage of green peanuts = 15%

Total = 0.12 + 0.15 + 0.12 + 0.23 + 0.23 + 0.15 = 1

Probability that a randomly selected peanut M&M is not orange:

P(orange)' = 1 - P(orange)

Where,

P(orange) = 23% = 0.23

Thus,

P(orange)' = 1 - 0.23

P(orange) ' = 0.77

Probability that a randomly selected peanut is not orange = 0.77

In the diagram below of triangle PQS, S is the midpoint of PR and T is the midpoint of QR. If ST = 5x - 22, and PQ = 3x + 19, wh

SIZIF [17.4K]

Answer:

PQ = 46

Step-by-step explanation:

The midsegment ST is half the length of the third side PQ , that is

ST = $\frac{1}{2}$ PQ , so

5x - 22 = $\frac{1}{2}$ (3x + 19) ← multiply both sides by 2 to clear the fraction

10x - 44 = 3x + 19 ( subtract 3x from both sides )

7x - 44 = 19 ( add 44 to both sides )

7x = 63 ( divide both sides by 7 )

x = 9

Then

PQ = 3x + 19 = 3(9) + 19 = 27 + 19 = 46

What is the total number of relative maximum and minimum points of the function whose derivative for all x is given by f ‘ (x) =

Alexeev081 [22]

Answer:

There are in total 3 maximum and minimum points of f(x)

Step-by-step explanation:

To find the number of stationary points (maximum and minimum points) in any function (f(x)), we need to find for what values of x does the derivative of f(x) equal to 0.

mathematically, for how many values of x does f'(x) = 0

$f'(x) = x(x-3)^2(x+1)^4$

$0 = x(x-3)^2(x+1)^4$

since the factors can be separately solved we can write

$0 = x, 0 = (x-3)^2, 0 = (x+1)^4$

$x= 0, \sqrt{(x-3)^2} = \sqrt{0}, \sqrt{(x+1)^4}=\sqrt{0}$

$x=0, (x-3)=0, (x+1)=0$

$x = 0, x = 3, x = -1$

Since there are 3 answers of x for which f'(x) = 0, we can say that the there are a total of 3 stationary (maximum or minimum) points in f(x).
