Can you help me solve my math problem here it is <br>f(x)=4x-9

Leokris [45]

f(1) = 4(1)-9 = 4-9 = -5

f(2) = 4(2)-9 = 8-9 = -1

f(3) = 4(3)-9 = 12-9 = 3

f(4) = 4(4)-9 = 16-9 = 7

Set would be {-5, -1, 3, 7 .....}

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:

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

What two whole numbers is the quotient between 37 divided by 6

Nitella [24]

Answer:

6 and 7

Step-by-step explanation:

To do this, we need to look at the two closest numbers that are divisible by 6. These are 36 and 42.

$36/6=6\\42/6=7$

As 37 is between 36 and 42, the quotient must be between 6 and 7
