Answer:

probability of chosing a student that has a cat and a dog is 9/25

Step-by-step explanation:

And yes the Venn diagram is wrong because you forgot to subtract 9 from 15 and 16

This makes it

[ 3 ( 6 ( 9 ) 7 ) ]

3 + 6 + 9 + 7 = 25

Consider the equations y = 3x and y = -12- x.

jasenka [17]

Answer:

x | -7 -5 -3

y | -21 -15 -9

Step-by-step explanation:

y = 3x

If x = -7 then y = 3 × (-7) = -21

x = -5 then y = 3 × (-5) = -15

x = -3 then y = 3 × (-3) = -9

The circular opening of a vase has an inside diameter of 13.5 cm.

Sunny_sXe [5.5K]

Answer:

$Area = 143cm^2$

Step-by-step explanation:

Given

Shape: Opening of a circular vase

$Diameter =13.5cm$

$\pi = 3.14$

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

$Area = \pi r^2$

Solve for radius (r)

$r = \frac{d}{2}$

$r = \frac{13.5\ cm}{2}$

$r = 6.75\ cm$

Substitute 6.75 for r in $Area = \pi r^2$

$Area = 3.14 * 6.75^2$

$Area = 143.06625$

$Area = 143cm^2$ --- Approximated

At what value of x does the graph of the following function F(x) have a vertical asymptote? F(x) = 4x/3x-6

riadik2000 [5.3K]

Answer:

vertical asymptote at x = 2

Step-by-step explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

3x - 6 = 0 ⇒ x = 2 ← is the vertical asymptote
