A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underw

ater. For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled, "The relation of dive duration (DD) to depth (D)." Duration DD is measured in minutes, and depth D is in meters. The report then says, "The regression equation for this bird is DD=2.69+0.0138D. What is the slope of the regression line?

Answer:

The slope of the regression line is 0.0138

Step-by-step explanation:

The problem tells us that there is a linear relationship between the dive duration and the depth.

Linear equations have the form y = mx + b where m is the slope, y is the dependent variable and x is the independent variable.

In this problem we have that the depth is the independent variable, the dive duration is the dependent variable and the regression equation is DD = 2.69 + 0.0138D where DD is the dive duration and D is the depth. From the previous paragraph, we can observe that the slope is the coefficient of the dependent variable. Therefore, for this equation the slope is 0.0138.

What’s the x-intercept of the graph of <br> 5x-4y= 20
viva [34]

The x-intercept of the graph is (4 , 0)

Step-by-step explanation:

Let us revise the meaning of x-intercept and y-intercept

  • x-intercept means value x when y = 0
  • That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
  • y-intercept means value of y when x = 0
  • That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0

∵ 5x - 4y = 20 is the equation of the graph

- To find x-intercept substitute y by 0

∵ y = 0

∴ 5x - 4(0) = 20

∴ 5x - 0 = 20

∴ 5x = 20

- Divide both sides by 5

∴ x = 4

The x-intercept of the graph is (4 , 0)

You buy 3 tickets for $48 total for the jazz concert on
statuscvo [17]

Answer: Friday night. Least expensive ticket

Step-by-step explanation:

Friday night.: 48/3 =16 so each ticket costs $16

Saturday night 36/2= 18 so each ticket costs $18

Brother collects 96/6 = 16. So each person had enough for a $16 ticket. They can go to the Friday night concert. They paid for the least expensive ticket.

Farmer Ed has 550 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fenc
ss7ja [257]
Let width of the rectangular plot be x meters

then total of widths = 2x 
and the length would be (550 - 2x) meters.

so the area = x(550 - 2x)  = 550x - 2x^2

to find the maximum are find the derivative and equate to zero:-

f'(x) =  550 - 4x = 0
x = 550/4 =  137.5 meters = width

length = 550 - 2(137.5) = 275

Maximum area  is when width = 137.5m and length = 275m
