Answer:

h(- 3) = - 1

Step-by-step explanation:

Substitute x = - 3 into h(x) , that is

h(- 3) = - 3(- 3) - 10 = 9 - 10 = - 1

The hourly wages of a sample of 130 system analysts are given below.
atroni [7]

Answer: b. 30%

Step-by-step explanation:

  • A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. CV=\dfrac{\sigma}{\mu}

Given: mean =  \mu=90

Variance = \sigma^2 = 729

\sigma=\sqrt{729}=27

Now, CV=\dfrac{27}{90}=0.3

in percent , CV= 0.3\times100\%= 30\%

Hence, correct option is  b. 30%.

Write an equation that is perpendicular to and 3x+y=3 whose y-intercept 5. Anyone please help me, no link just explain how to do
Liula [17]

Answer:

y = \frac{1}{3}x + 5

Step-by-step explanation:

By definition, two lines are perpendicular if and only if their slopes are negative reciprocals of each other:  m = - \frac{1}{m_{2} }, or equivalently, m_{1} * m_{2} = -1.

Given our linear equation  3x + y = 3  (or y = -3x + 3):

We can find the equation of the line (with a y-intercept of 5) that is perpendicular to y = -3x + 3 by determining the negative reciprocal of its slope, -3, which is \frac{1}{3}.

To test whether this is correct, we can take first slope,  m_{1} = -3,  and multiply it with the negative reciprocal slope m_{2} = \frac{1}{3} :

m_{1} * m_{2} = -1

-3 * \frac{1}{3}  = -1

Therefore, we came up with the correct slope for the other line, which is  \frac{1}{3}.

Finally, the y-intercept is given by (0, 5). Therefore, the equation of the line that is perpendicular to 3x + y = 3 is:

y = \frac{1}{3}x + 5
