There are 145 total pieces . you must first convert 20% to a decimal by placing a decimal point two places from the right. 20% = .20
then you mulitiply 145 x .20 = 29
So, Cathy owns 29 pieces of yellow clothing.

0.3% of a country has a certain disease. The test for the disease has a sensitivity of 92% (i.e., of those we know have the dise

butalik [34]

Answer:

0.95988 (Accuracy of the test )

Step-by-step explanation:

To determine the accuracy of this test we have to list out the given values

Prevalence rate of the disease = 0.3% = 0.003

sensitivity rate of the disease = 92% = 0.92

specificity rate for the test = 96% = 0.96

The accuracy of the test can be found using this equation

Accuracy = sensitivity * prevalence + specificity ( 1 - prevalence )

= 0.92 * 0.003 + 0.96 ( 1 - 0.003 )

= 0.00276 + 0.95712

= 0.95988

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.

faltersainse [42]

Answer:

V = 34,13*π cubic units

Step-by-step explanation: See Annex

We find the common points of the two curves, solving the system of equations:

y² = 2*x x = 2*y ⇒ y = x/2

(x/2)² = 2*x

x²/4 = 2*x

x = 2*4 x = 8 and y = 8/2 y = 4

Then point P ( 8 ; 4 )

The other point Q is Q ( 0; 0)

From these two points, we get the integration limits for dy ( 0 , 4 )are the integration limits.

Now with the help of geogebra we have: In the annex segment ABCD is dy then

V = π *∫₀⁴ (R² - r² ) *dy = π *∫₀⁴ (2*y)² - (y²/2)² dy = π * ∫₀⁴ [(4y²) - y⁴/4 ] dy

V = π * [(4/3)y³ - (1/20)y⁵] |₀⁴

V = π * [ (4/3)*4³ - 0 - 1/20)*1024 + 0 )

V = π * [256/3 - 51,20]

V = 34,13*π cubic units
