Answer: Both answers equal 198

Step-by-step explanation:

While at first this problem may look weird and even stump you. However, break it up.

What is 273-75? 198

What is 280-82? 198

The reason both equation equals each other are because both have the same answer.

Another example problem: 100-1=26+73

100-1= 26+73

100-1 = 99

26+73 = 99

The answer is 198
273-75 = 198
280-82=198
so it’s 198=198

I need to know the answer and work

Basile [38]

Answer:

$2\sqrt{17}$

Step-by-step explanation:

Given:

$\sqrt{68}$

To find:

Simplified result of the radical

Solution:

If a value is in square root and it is not a perfect square then we can solve it by finding the answer by factoring down it to smaller factors which are perfect squares and finding the square root of the smaller values

Now

68 can be written as

68 = 2 * 2 * 17

The given is

$\sqrt{68}$

It can be written as

$\sqrt{68}=\sqrt{2*2*17}$

= $\sqrt{2^{2}*17}$

Now

$\sqrt{a.b}$ = $\sqrt{a}$ . $\sqrt{b}$

so given become

$\sqrt{68}=\sqrt{2^{2}}*\sqrt{17}$

$\sqrt{68}=2*\sqrt{17}$ ∵√2² = 2

$\sqrt{68}=2\sqrt{17}$ ∵a*√b=a√b

A bag contains 4 red balls and 6 blue balls. If 3 balls are selected at random, find the probability of selecting 3 red balls?

Paha777 [63]

The probability is 4⋅3⋅2⋅1/10•9•8•7=(4/4)(6/0)/(10/4)=1/210 so the probability of selecting 3 red balls would be 1/210

4. After measuring the mass of water, the data is averaged and it is determined that the mean of 4 measurements is 122.4 g with

pogonyaev

The mass of the object would be the mean which is 122.4, which must be rounded to three significant figures, i.e 122 g.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

After measuring the mass of water,

the data is averaged and it is determined that the mean of 4 measurements is 122.4 g with a standard deviation of 1.3 g.

If the deviation is 1.3 g then, the true measurement will be

122.4g - 1.3g to 122.4g + 1.3g:

Lower limit: 122.4 g - 1.3 g

= 121.1 g

Upper limit: 122.4 g + 1.3 g

= 123.7 g

only the first two digits, hundreds and tens places, are certain.

The one digit is uncertain.

It should report the number with three significant figures:

2 certain digits + 1 uncertain digit.

The mass of the object would be the mean which is 122.4,

which must be rounded to three significant figures, i.e 122 g.
