Intelligent failure occur when you experiment in order to learn under conditions of high uncertainty

It's always possible to move forward from failure stronger and wiser. To do this, we must

a) descry and accept our failures snappily,

b)Dissect what happed and how it happed effectively to maximize what we can learn,  

c)Apply our literacy to change our mindsets, behaviours, and the way we do our work, and

d)Continue to take smart pitfalls and introduce, icing we make better miscalculations on our coming bold attempt.

The probability of pulling out a red marble 3 times in a row will be 1/64.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Marbles: You have a bag with 3 red marbles, 4 blue marbles, and 5 green marbles.

Then the probability of pulling out a red marble 3 times in a row will be

The total number of events will be

Total events = 3 + 4 + 5 = 12

The favorable event will be

Favorable event = 3

Then the probability will be

P = (3/12)(3/12)(3/12)

P = (1/4)(1/4)(1/4)

P = 1/64

Answer:

Firstly, we'll apply the below identity.

[tex]{\boxed{\sf{(a+b)^{2} = a^{2} + b^{2} +2ab}}}[/tex]

Applying the above identity.

⇒ (√5 + √2)²

⇒ (√5)² + (√2)² + 2×(√5)×(√2)

⇒ 5 + 2 + 2√10

⇒ 7 + 2√10

Comparing the LHS and RHS

⇒ 7 + 2√10 = a + b√10

∴ a = 7 and b = 2.

The solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

to determine the solutions of the equation:

The equation is given as:

|2/3x + 2| − 8 = 0

Start by adding 8 to both sides of the equation.

So, we have

|2/3x + 2| = 8

Next, we remove the absolute value expression

So, we have;

2/3x + 2 = 8 and 2/3x + 2 = -8

Subtract 2 from both sides of the equation

2/3x = 6 and 2/3x = -10

Multiply the equation by 3/2

x = 9 and x = -15

Hence, the solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

285714 / 1000 000    which simplifies to 142,857 / 500,000

The correct options, in order, are:

[tex]f(n) = 3*(2)^{n-1}[/tex]

[tex]f(n) = 2*(6)^{n - 1}[/tex]

[tex]f(n) = 2*(4)^{n - 1}[/tex]

The first table is:

n   f(n)

1     3

2    6

3    12

Notice that when n = 1, all the exponents are 0, then the initial value is 3.

When n = 2, all the exponents are 1. Then we need to find the exponential equation with a base equal to 2.

So the exponential equation is:

[tex]f(n) = 3*(2)^{n-1}[/tex]

The second table is:

n   f(n)

1     2

2    12

3    72

By looking at the first pair, we conclude that the initial value is 2, and by looking at the second pair, we conclude that:

2*b = 12

b = 12/2 = 6

The base is 6.

So the exponential equation now is:

[tex]f(n) = 2*(6)^{n - 1}[/tex]

The last table is:

n   f(n)

1     2

2    8

3    32

Here we again have an initial value of 2, and the base is:

2*b = 8

b = 8/2 = 4

Then the correct option now is:

[tex]f(n) = 2*(4)^{n - 1}[/tex]

Applying the knowledge of fractions, the bigger one is: one-sixth of 138.

Fractions can be defined as a part of a digit or number, and are not whole numbers. For example, a third is 1/3, one-sixth is 1/6, which are both fractions.

Therefore, let's evaluate each statement:

1/3 of 45 = 1/3 × 45 = 15

1/6 of 138 = 1/6 × 138 = 23

Therefore, the bigger of the two is: one-sixth of 138.

The probability that he will be rejected to at least one of the colleges is 0.51.

Given probability that he will admit in A is 0.7, probability that he will not be admit in B is 0.5, probability that atleast one of his applications got rejected is 0.6.

We have to find the probability that he will be rejected to at least one of the colleges.

Probability that he will admit in A =0.7

Probability that he will not admit in A=1-0.7=0.3

Probability that he will not admit in B =0.5

Probability that he will admit in B=1-0.5=0.5

Probability  that he will be rejected to at least one of the colleges=probability that he will admit in A* probability that he will not admit in B+ probability that he will admit in B* probability that he will not admit in A+ probability that he will not admit in A* probability that he will not admit in B

=0.7*0.5+0.5*0.3+0.5*0.3

=0.35+0.15+0.15

=0.51

Hence the probability that he will be rejected to at least one of the colleges is 0.51.

Step-by-step explanation:

Answer: [tex]60cm^2[/tex]

Step-by-step explanation:

Looking at the figure, you can see that the length is 5cm + 3cm = 8cm and the width is 2cm + 5cm + 2cm = 9cm.

The formula for area is length x width, therefore you do 8x9 which is 72.

Next, we solve for the two "dips" in the rectangle. We can do that by subtracting the area of the "mini-rectangles" from the whole figure:

72-2(2x3) = 60

Thus, 60cm^2 is your answer.
