The numbers inside the parenthesis is the value of x, uses the equation associated with the value of x and solve.

H(1) Since 1 fits 1≤x≤3 use x^3

x^3 1^3 = 1

h(1) = 1

h(4) 4 fits x >3, so use 5

h(4) = 5

How do you find the slope.and y-intercept of y= 1/3-2
NikAS [45]

Answer:

The slope in that equation is 1/3 so you would go up on the coordinate plane one, and over three. The y intercept, is 2. Any linear equation in slope intercept form, y=mx+b,  will be set up that way, so hopefully this helps, it's the easiest way to find the slope and y intercept, m is always the slope, and b is always the y intercept. :)

The bass in Clear Lake have weights that are normally distributed with a mean of 2.2 pounds and a standard deviation of 0.6 poun
Papessa [141]

Answer:

Step-by-step explanation:

(a) What is the mean fish weight of your catch of 6? Round your answer to 1 decimal place.  =Total weight/no of fish in sample

_\frac{15.9}{6} =2.65_____ pounds

(b) If 6 bass are randomly selected from Clear Lake, find the probability that the mean weight is greater than the mean of those you caught. Round your answer to 4 decimal places.

___P(mean >2.65)=P(Z>\frac{2.65-2.2}{\frac{0.6}{\sqrt{0.6} } } \\=P(Z>0.18)\\=0.5-0.0714=0.4286_____

Sample mean follows a normal distribution with mean = 2.2 and std error = 0.6/sqrt 6

(c) Which statement best describes your situation?

_____ This is not particularly unusual because the mean weight of your fish is only 0.5 pounds above the population average.

What is the approximate volume of the tube? Round to the
vladimir2022 [97]

Answer:

The approximate volume of the tube  is 1,005 cm³

Step-by-step explanation:

To find the volume of the tube, we will follow the steps below:

First, write the formula for calculating the volume of a cylinder

volume of a cylinder = πr²h

where r is the radius and h is the height of the cylindrical cardboard tube

from the question given, height is equal to 20 centimeters    and             diameter = 8 centimeters  but diameter = 2r, this implies that r = d/2   hence radius r =8/2 = 4 centimeters

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a cylinder = πr²h

                                 ≈ 3.14 × 4²× 20

                                   =3.14 × 16× 20

                                    ≈1,005 cm³ to the nearest whole cubic centimeter.

The approximate volume of the tube  is 1,005 cm³
