Round 8.87689068442 to 2 decimal places.

Marizza181 [45]

Answer:

The answer is 8.88; You look at the number that comes after the second number (the second place after the decimal) and if that number is 5 or above then you round the second number up. (Sorry if it doesn't make sense, but that's the best I can explain it).

In a bag of m&m's there are 5 brown 6 yellow 4 blue 3 green and 2 orange. What's the probability of getting 3 yellow m&m

olasank [31]

There are 5+6+4+3+2=20 m&m's in the bag.
Calculate in how many ways you can choose 3 m&m's from 20:
$_{20} C _3=\frac{20!}{3!(20-3)!}=\frac{20!}{3! \times 17!}=\frac{17! \times 18 \times 19 \times 20}{6 \times 17!}=\frac{18 \times 19 \times 20}{6}=3 \times 19 \times 20= \\
=1140$

There are 6 yellow m&m's.
Calculate in how many ways you can choose 3 m&m's from 6:
$_6 C _3 = \frac{6!}{3!(6-3)!}=\frac{6!}{3! \times 3!}=\frac{3! \times 4 \times 5 \times 6}{3! \times 6}=\frac{4 \times 5 \times 6}{6}=4 \times 5=20$

The probability is the number of ways of choosing 3 m&m's from 6 m&m's divided by the number of ways of choosing 3 m&m's from 20 m&m's.
$P=
\frac{20}{1140}=\frac{20 \div 20}{1140 \div 20}=\frac{1}{57}$

The probability is 1/57.

Select the correct answer from each drop-down menu. Andy is designing a dice tray in the shape of a rectangular prism to use dur

-BARSIC- [3]

Answer:

w = 7 cm

Step-by-step explanation:

Volume = 252 cm³

Height, h = 3cm

Let width = w

Length, l = w + 5

Volume of rectangular prism, V = l * w * h

252 = (w + 5) * w * 3

252 = (w + 5) * 3w

252 = 3w² + 15w

3w² + 15w - 252 = 0

w² + 5w - 84 = 0

w² + 12w - 7w - 84 = 0

w(w + 12) - 7(w + 12) = 0

(w + 12) = 0 or (w - 7) = 0

w = - 12 or w = 7

w cannot be negative

Hence, w = 7 cm

If in drawing your vector you are required to use a scale such that 25 grams represent 1 cm, and if your resultant vector measur

Aleks04 [339]

If we multiply the ratio

... 25 g : 1 cm

by 5, we get

... 125 g : 5 cm

The number on the left is 75 g more than 50 g.
