Divide 56 in the ratio 5 3

2 answers:

8 0

Hey there :)

The given value is 56

We need to divide in the ratio 5 : 3

We can do it this way:

5x + 3x = 56

8x = 56

$\frac{8x}{8} = \frac{56}{8}$
8 and 8 cancels out

x = 7

5(7) : 3(7)
35 : 21

I don't understand what you need.

But,

5 + 3 = 8

56/8 = 7

7*5 = 35
7*3 = 21

Hope this helps !

Find the variance of this probability distribution. Round to two decimal places.

attashe74 [19]

Answer:

Variance = 4.68

Step-by-step explanation:

The formula for the variance is:

$\sigma^{2} =\frac{\Sigma(X- \mu)^{2}}{N} \\or \\ \sigma^{2} =\frac{\Sigma(X)^{2}}{N} -\mu^{2} \\$

Where:

$X: Values \\\mu: Mean \\N: Number\ of\ values$

The mean can be calculated as each value multiplied by its probability

$\mu = 0*0.4 + 1*0.3 + 2*0.1+3*0.15+ 4*0.05=1.15$

$\frac{\Sigma (X)^{2}}{N} =\frac{(0^{2}+1^{2}+2^{2}+3^{2}+4^{2})}{5} =6$

Replacing the mean and the summatory of X:

$\sigma^{2} = \frac{\Sigma(X)^{2}}{N} -\mu^{2} \\= 6 - 1.15^{2}\\= 4.6775$

Simplity: 17 (-12 + 3)

Schach [20]

Answer:

$\Huge\boxed{\mathsf{-153}}}$

Step-by-step explanation:

$\Large\boxed{\mathsf{LESSON: ORDER \quad OF \quad OPERATIONS}}}$

$\Large\boxed{\mathsf{SUBJECT: MATH}}}$

To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.

First, do parenthesis.

17(-12+3)

(-12+3)=-9

17(-9)

Then, multiply.

17*9=153

17(-9)=-153

-153

$\Large\boxed{\mathsf{\Rightarrow -153}}$

The correct answer is -153.
