How do you calculate this
Alexxx [7]

Answer:

y = - 2x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m = \frac{-1-1}{0-(-1)} = \frac{-2}{0+1} = \frac{-2}{1} = - 2

the line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = - 2x - 1 ← equation of line

The distribution of bladder volume in men is approximately normal with mean 550 ml and standard deviation 100 ml. what percent o
ruslelena [56]

To solve this, we use the z-test.

z = (x – u) / σ

when x = 450

z = (450 – 550) / 100

z = -1

 

We use the standard distribution tables to find for P.

P = 0.1587

 

Since we are looking for values greater than x = 450, therefore:

1 – 0.1587 = 0.8413

 

This means that 84.13% have bladder volume larger than 450 mL.

PART A

Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box

PART B

Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.
