The probability of randomly selecting two oranges from a bowl of 5 oranges and 4 tangerines if the first selection is replaced

denis-greek [22]

Answer:

25/81

Step-by-step explanation:

The probability of randomly selecting two oranges = (number of oranges in the bowl / total number of fruits in the bowl) x (number of oranges in the bowl / total number of fruits in the bowl)

total number of fruits in the bowl = 5 + 4 = 9

5/9 x 5/9 = 25/81

Which of the following lists is in order from smallest to largest?

Stells [14]

Answer:

The following list is in order from smallest to largest is $17\%,0.175,\frac{2}{11},\frac{1}{5}$

Step-by-step explanation:

Let the numbers be $\frac{2}{11},\frac{1}{5},17\%,0.175$

To find the list in order from smallest to largest:

$\frac{2}{11},\frac{1}{5},17\%,0.175$

Rewritting the above numbers as below

$0.18,0.5,\frac{17}{100},0.175$

$0.18,0.5,0.17,0.175$

Now arranging the numbers in order from smallest to largest

$0.17,0.175,0.18,0.5$

$\frac{17}{100},0.175,\frac{2}{11},\frac{1}{5}$

The arranged numbers can be written as

$17\%,0.175,\frac{2}{11},\frac{1}{5}$

The following list is the order from smallest to largest is $17\%,0.175,\frac{2}{11},\frac{1}{5}$

Choose the answer based on the most efficient method as presented in the lesson.

Mashcka [7]

Answer:

You would not subtract 3...

Step-by-step explanation:

It should be

2x- 8= 5x+3

subtract 5x from both sides,

then add 8 onto both sides, then you would get 0 on one side, and 11 on the other so you would have

-3=11 which equals

Which statement is correct?

Arisa [49]

Answer:

$2.06 \times 10^-^2 = 206$

$1.88 \times 10^-^1 = 18.8$

$206 \times 18.8 = 3,872.8$

$7.69 \times 10^-^2 = 769$

$2.3 \times 10^-^5 = 230,000$

$=\frac{769}{230000}$

= 0.00334

therefore,

3,872.80 > 0.00334

Step-by-step explanation:

Which statement is correct?

(2.06x102x1.88 x 10-1) <7.69x 10

2.3x10-5

(2.06 x 10-2)(1.88 x 10-1) 7.69x 10-

2.3x10-5

7.69 x 10"

(2.06 x 10-2x1.88x10-)>

2.3x10-5

(2.06x 10-2X(1.88x 10-1)-7.69x104

2.3x10-5

Given that;

$2.06 \times 10^-^2 = 206$

$1.88 \times 10^-^1 = 18.8$

$206 \times 18.8 = 3,872.8$

$7.69 \times 10^-^2 = 769$

$2.3 \times 10^-^5 = 230,000$

$=\frac{769}{230000}$

= 0.00334

therefore,

3,872.80 > 0.00334

The volume of a packing box is 5 – x cubic feet. The width of the box is x feet and the length is x – 2 feet. The height is give

photoshop1234 [79]

By definition we have that the volume is given by
V = h * w * l
where
V: Volume
h: height
w: width
l: length
Clearing the height we have:
h = V / (w * l)
h = (5 - x) / ((x) * (x - 2))
The expression is not defined for the values of x that make the denominator zero:
((x) * (x - 2)) = 0
x = 0
x = 2
Answer
h = (5 - x) / ((x) * (x - 2))
x = 0
x = 2
