2 friends share 3 fruit bars equally. How much does each friend get?

2 answers:

7 0

Each friend would get 1 bar. This would leave an extra bar. Simply divide that third bar in half to give the 2 friends equal amounts. The 2 friends would get 1.5 or 1 1/2 fruit bars each.

The probability that a high school student in in the marching band is 0.47. The probability that a student plays a varsity sport

IrinaK [193]

The probability that a high school student in in the marching band is 0.47

so, $P(M)=0.47$

The probability that a student plays a varsity sport is 0.32

so, $P(V)=0.32$

the probability that a student is in the marching band and plays a varsity sport is 0.24

so, we get

P(M∩V)=0.24

a student plays a varsity sport if we know she is in the marching band

so,

P(V|M)=(P(V∩M))/(P(M))

now, we can plug values

and we get

$P(V|M)=\frac{0.24}{0.47}$

$P(V|M)=0.51063$

So,

the probability that a student plays a varsity sport if we know she is in the marching band is 0.51063......Answer

For each of the described curves, decide if the curve would be more easily given by a polar equation or a Cartesian equation. Th

Reptile [31]

Answer:

(a) (x-2)^2 +(y-2)^2 = 16

(b) r = 2

Step-by-step explanation:

(a) When the circle is offset from the origin, the equation for the radius gets messy. In general, it will be the root of a quadratic equation in sine and cosine, not easily simplified. The Cartesian equation is easier to write.

Circle centered at (h, k) with radius r:

(x -h)^2 +(y -k)^2 = r^2

The given circle is ...

(x -2)^2 +(y -2)^2 = 16

(b) When the circle is centered at the origin, the radius is a constant. The desired circle is most easily written in polar coordinates:

r = 2

Select all quantities that are proportional to the diagonal length of a square.

horsena [70]

Answer:

B. Perimeter of a square and

C. Side length of a square

Step-by-step explanation:

if n= side length of square then

Area of square is $n^{2}$
Perimeter of a square is 4×n
diagonal length of a square is $\sqrt{2}$ × n

Thus,

Perimeter of square can be expressed as

$2\sqrt{2}$ ×diagonal length of a square

Side length of a square can be expressed as

$\frac{1}{\sqrt{2} }$ ×diagonal length of a square

but Area of square is

$\frac{1}{\sqrt{2} }$ ×n×diagonal length of a square

As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
