explain why any number less than 12.5 and greater than or equal to 11.5 with round 2 12 when rounded to the nearest whole number

the sum of the lengths of the sides of a rectangle is represented by 32 feet. the width of the rectangle measures 9 feet. what i

Marina CMI [18]

-- A rectangle has 4 sides.

-- Each side has the same length as the side directly across from it.

-- So there are two sides that are both the width of the rectangle,
and another two sides that are both the length of the rectangle.

-- In this particular rectangle, when you add up all four sides,
the sum is 32 feet.

-- The width of the rectangle is 9 feet. So there are two sides that are
both 9 feet. When you add those up, you have 18 feet.

-- The REST of the 32 feet belongs to the other two sides.
That much is (32 - 18) = 14 feet. That's what the other two
sides add up to when you add them.

-- The other two sides are equal. So each of them is half of 14 = 7 feet .

This rectangle, or the description of it, is slightly weird.
The length of the rectangle is shorter than the width.
But that's OK. Two sides are 9 feet, and two sides are 7 feet, and
when you add them all up, you get 32 feet, so our solution is correct.
Let them call the sides anything they want to.

Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like

blsea [12.9K]

Answer:

Total songs = 15

Liked songs = 3

Un liked songs = 15-3=12

Find the probability that among the first two songs played

(a) You like both of them.

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{2}{14} = 0.029$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{11}{14} = 0.629$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{14}+ \frac{12}{15} \times \frac{3}{14}= 0.343$

(d) Redo (a)-(c) if a song can be replayed before all

(a) You like both of them. Would this be unusual?

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{3}{15} = 0.04$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{12}{15} = 0.64$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{15}+ \frac{12}{15} \times \frac{3}{15}= 0.32$

Which of these best describes the hypotenuse-angle theorem?

Amiraneli [1.4K]

The hypotenuse angle theorem basically states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.

So I would say D is correct

Find the area of the parallelogram. 4 m 11 m

agasfer [191]

Answer:

The area of this parallelogram is $44meters^2$

Step-by-step explanation:

The formula for working out the area of a parallelogram is : $base*height$

To work out the area you would multiply the base of 11 by the height of 4, this gives you 44 meters squared. This is because a identical parallelogram and a rectangle would have the same area.

1) Multiply 11 by 4.

$11*4=44 meters^2$
