Answer:

1/8 or 5/40

Step-by-step explanation:

You need to first create a fraction which would be 5/40 since the formula of probability is number of outcomes in a / number of outcomes in the sample space.

Simplify the fraction

5/40 = 1/8

We have this function here:

f(x)=x^2-3x-14

We can differentiate this function using the power rule:

\frac{d}{dx}x^n=nx^{n-1}

We will subtract the power/exponent by 1 and multiply the original exponent to the constant in front.

f^{\prime}(x)=2x-3

The differentiated function is shown above.

Reason 1

Given

Statement 2

4x=8(x-2)

4x = 8x - 16

4x - 8x = - 16

-4x = - 16

Reason 3

You want to get at least 48 people to your costume party. Your 12 best friends will definitely be there. For every time you twee
Natasha_Volkova [10]

The number of tweets that's will be needed to send to get at least 48 people will be at least 9 tweets.

Let the number of tweets be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

12 + (4 × x) ≥ 48

12 + 4x ≥ 48

Collect like terms.

4x ≥ 48 - 12

4x ≥ 36

x ≥ 36/4

x ≥ 9

Therefore, 9 or more tweets will be needed.

∆ABC m∠B = 90° AB = 4 BC = 3<br> Find AC
lutik1710 [3]

Step-by-step explanation:

In ∆ABC, m∠B = 90°

Therefore ∆ABC is a right angled triangle with sides AB = 4 & BC = 3. AC is the hypotenuse.

Hence, by Pythagoras theorem:

AC^2 = AB^2 +BC^2  \\  \\  \therefore \: AC =  \sqrt{AB^2 +BC^2 }  \\  =  \sqrt{ {4}^{2} +  {3}^{2}  }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}  \\  = 5 \\  \\ \huge \red{ \boxed{ \therefore \: AC = 5 \: units}}
