The length of a rectangle is twice its width. The perimeter of the rectangle is 24 inches. Write a system of equations in 2 vari

Nadya [2.5K]

The width can be x.
so it means that the length is 2x
the equation would be
2(x+2x)=24 inches
2x+4x= 24
6x= 24
x=4 (this is the width, so the length will be 8 inches)
the area will be 4 times 8 = 32

Answer:

C. Children have much greater chance of having side effects than adults.

Step-by-step explanation:

It is known that the conditional probability for two events A and B is given by,

$P(A|B)=\frac{P(A\cap B)}{P(B)}$ .

Then, according to the table, we have,

$P(sideeffects|child)=\frac{P(sideeffects\cap child)}{P(child)}$

i.e. $P(sideeffects|child)=\frac{20}{50}$

i.e. $P(sideeffects|child)=0.40$

Moreover,

$P(sideeffects|adult)=\frac{P(sideeffects\cap adult)}{P(adult)}$

i.e. $P(sideeffects|adult)=\frac{6}{50}$

i.e. $P(sideeffects|adult)=0.12$

As 0.40 > 0.12.

Children have more chances of having side effects than adults.

Hence, option C is correct.

Complete the function table

olga55 [171]

Answer:

8, 6, 3, 2, 1

Step-by-step explanation:

g(x) = -x + 3

using g(x),

g(-5) = (-1 x -5) + 3

= 5 + 3

= 8

g(-3) = (-1 x -3) + 3

= 3 + 3

= 6

g(0) = 0 + 3

= 3

g(1) = -1 + 3

= 2

g(2) = -2 + 3

= 1

A grid shows the positions of a subway stop and your house. The subway stop is located at (7,3) and your house is located at (4-

Kryger [21]

Answer:

9 units

Step-by-step explanation:

In a coordinate plane with point P( x , y) and Q(a,b ).

distance between these are points is given by equation

distance between PQ = $\sqrt{(x-a)^2 + (y-b)^2}$ .

Coordinate of subway stop = (7,3)

Coordinate of house = (4-5)

Therefore using the above the formula to calculate distance between

house and the subway stop is given by

distance = $\sqrt{(7-4)^2 + (3-(-5)^2}\\\\=>\sqrt{(3)^2 + (3+5)^2}\\\\=>\sqrt{9 + (8)^2}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{73}\\\\=>8.544$

Therefore, distance between house and the subway stop is 8.544 units.

But it is given that distance should be to the nearest unit.

any decimal value greater than or equal to .5 is equivalent to 1 in nearest unit.

Thus, 8.544 units is equivalent to 9 units (in nearest unit)
