2/9 ÷ 5/12
= 2/9 × 12/5 Reciprocal of 5/12
= 2×12 / 9×5 Multiply num. by num. and denom. by denom.
= 24 / 45 Find LCD
= 24 ÷ 3 / 45 ÷ 3 Divide num. and denom. by LCD to simplify.
= 8 / 15

Therefore the answer is 8/15

Answer:

Follows are the solution to this question:

Step-by-step explanation:

please find the complete question in the attached file.

female = 23 and male = 19 faculty members

Randomly selected member are = 6

In point 1:

The Probability to equally selecting men and women:

$= \frac{(23C3+19C3)}{42C6}$

In point 2:

The Probability of selecting at least 4 men:

$= \frac{((19C4 \times 23C2)+(19C5 \times 23C1)+(19C6))}{42C6}$

In point 3:

The probability in which no women are chosen implies that 6 selected members are from 23 women:

$= \frac{23C6 }{42C6}$

In point 4:

The Probability in which no more than 4 women are selected:

$\frac{((19C6)+(23C1 \times 19C5)+(23C2 \times 19C4)+(23C3 \times 19C3)+(23C4 \times 19C2))}{42C6}$

A toaster oven usually sells for $68. If the toaster oven is 20% off, and sales tax is 6%, what is the total price of the toaste

sertanlavr [38]

Answer:

Step-by-step explanation:

20% discount is 1/5 x 68 = 13.60

So pre-tax price is 68 - 13.60 = 54.40

Add sales tax:

54.40 x 1.06 = 57.66

so the answer is C

A certain mapping in the xy plane has the following property: Each point P with coordinates (x,y) is mapped to a point P'with co

NeTakaya

Answer:

C.The property defines a translation

Step-by-step explanation:

We are given that a certain mapping in the xy-plane

Each point P (x,y) is mapped to a point P'(x-5,y-2).

We have to find that which statement is true in given option.

It is not reflection property because reflection about any axis then the coordinate does not change only sign of x and y change depend upon the reflection about x- axis or y- axis.

Therefore,option A is false.

Rotation:it is a transformation that turns a figure about a fixed point called center of rotation.

Rotation can be 90 degrees , 180,270 and 360 degrees

If the point P rotate 90 degrees then the point P'(-y,x),If point P rotate about 180 degrees then the point P'(-x,-y), when the point P rotate about 270 degrees then the point P'(y,-x), when the point P rotate about 360 degrees then the point P'(x,y).

Therefore, it is not a rotation.

It is a translation property because in translation every point must move same distance.
