Answer:

3/35

Step-by-step explanation:

total bottles 7/7

4/7 are big,

7/7-4/7=3/7 remaining bottles.

4/5×3/7=12/35 are small.

you add the big bottles and small bottles

4/7+12/35=32/35

then you minus from the total which is 7/7

7/7-32/35=3/35 are tiny.

Answer:

14 is the correct answer. It is just the inverse of 5+9 but it equals the same

Step-by-step explanation:

Answer:

below

Step-by-step explanation:

First we need to find the domain.

x^2+ y^2 = 8

√x^2 + √y^2 = √8

x + y = ±2√2

So the domain is ±2√2. If you graph the circle you will see that it will in fact fail the vertical line test, mainly because its a circle. If you graph the domain onto the circle, you will see that it will have an affect on it being a relation. A graph will be shown below for a better reference. Keep in mind that ±2.828 is the decimal form of ±2√2.

0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.

-----------------------------------

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Event A: Your friend wins the first prize.

Event B: You win the second prize.

-----------------------------------

Probability friend wins first prize:

10 out of 100 tickets, so:

[tex]P(A) = \frac{10}{100}[/tex]

-----------------------------------

Probability you win second prize:

There will be 99 tickets remaining(1 has been sorted), you have then of then, so:

[tex]P(B) = \frac{10}{99}[/tex]

-----------------------------------

What is the probability that your friend wins the first prize and you win the second prize?

Multiplication of the probabilities, thus:

[tex]p = P(A) \times P(B) = \frac{10}{100} \times \frac{10}{99} = \frac{10\times10}{100\times99} = 0.0101[/tex]

0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.

Answer:

We have to use addition or subtraction property of equality to determine the value of variable involve.

Step-by-step explanation:

Example with variable term:

3x=4-x

Add x on both sides of equation:

3x+x=4-x+x

4x=4

x=1

Example with contact involve:

5y+7=12

Subtract 7 from both sides

Answer:

Step-by-step explanation:

The y intercept occurs when x = 0.

All you have to do is read the table until you come to x = 0.

When you do, read down to get the y value.

The answer is A (0,2)

Answer:

Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms

Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728

Now,

[tex]Sum = \frac{a( {r}^{n} - 1) }{(r - 1)} \\ [/tex]

So,

[tex] \frac{a( {r}^{n} - 1)}{(r - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{(3 - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{2} = 728 \\ {3}^{n} - 1 = 728 \\ {3}^{n}=728+1\\ {3}^{n} = 729 \\ {3}^{n} = {3}^{6} \\ \boxed{ n = 6}[/tex]

Therefore, number of terms is 6

Its a GP given by 2+6+18

Common ratio=r=

[tex]6.6 = 3z - 50.7 - ( - 0.6)[/tex]

[tex]6.6 = 3z - 50.7 + 0.6[/tex]

[tex]6.6 = 3z - 50.1[/tex]

[tex]6.6 - 3z = - 50.1[/tex]

[tex] - 3z = - 50.1 - 6.6[/tex]

c similarly 160

Answer:

Step-by-step explanation:

Yes, the irrational number stays irrational.

Make the assumption that this statement is false and that a rational and an irrational can produce a rational. x is irrational. Assume that a, b, c, and d are all integers.  If you like, they can be relatively prime to each other.

a/b + x = c/d                   Subtract a/b from both sides.

x = c/d - a/b                    Now put the 2 fractions over a common denominator.

x = (c*b - d*a)/(b*d)         Investigate what you have.

b*d are two integers multiplied together. multiplication of integers is closed (the answer will be an integer).

cb and da are also integers. subtracted integers are also closed under subtraction.

But

Here's the kicker. An irrational number is one that cannot be expressed as a fraction. Sqrt(2) for example cannot be shown to be rational. There is no fraction that equals sqrt(2)

So our proof is "bogus." It cannot work. An irrational number excludes the possibility of being able to be represented by a fraction by definition.
