A piecewise function g(x) is represented by the graph. On a coordinate plane, a piecewise function has 3 lines. The first line h

fenix001 [56]

Answer:

see the explanation

Step-by-step explanation:

Find out the equation of each line of the piece wise

First line

The first line has an open circle at (negative 2, negative 2) and it continues horizontally to an open circle (negative 5, negative 2)

(-2,-2) to (-5,-2)

$g(x)=-2$

$-5 < x < -2$

Second line

The second line has a closed circle at (negative 2, 0) and then continues up to an open circle at (1, 1.5)

[-2,0] to (1,1.5)

Find the slope

$m=(1.5-0)/(1+2)=0.5$

Equation in point slope form

$y-y1=m(x-x1)$

we have

$m=0.5$

$point (-2,0)$

substitute

$y-0=0.5(x+2)$

Convert to slope intercept form

$y=0.5x+1$

$g(x)=0.5x+1$

$-2 \leq x < 1$

Third line

The third line has a closed circle at (1, 4) and continues down to open circle (5, negative 4). Which functions represent a piece of the function?

[1,4] to (5,-4)

The equation of the line is

$g(x)=-2x+6$ ---> Repeat all steps that in second line

$1 \leq x < 5$

therefore

The piece wise function is equal to

$g(x)=-2$ ----> $-5 < x < -2$

$g(x)=0.5x+1$ ----> $-2 \leq x < 1$

$g(x)=-2x+6$ ---> $1 \leq x < 5$

A geologist examines 6 seawater samples for lead concentration. The mean lead concentration for the sample data is 0.903 cc/cubi

Gnesinka [82]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the mean lead concentration of sea water samples

Number of samples. n = 6

Mean, u = 0.903 cc/cubic meter

Standard deviation, s = 0.0566

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

0.903 +/- 1.96 × 0.0566/√6

= 0.903 +/- 1.96 × 0.0566/2.44948974278

= 0.903 +/- 0.045

The lower end of the confidence interval is 0.903 - 0.045 =0.858

The upper end of the confidence interval is 0.903 + 0.045 =0.948

Therefore, with 95% confidence interval, the mean lead concentration of the sea water is between 0.858 cc/cubic meter and 0.948 cc/cubic meter

Can someone help me with this math homework please!

salantis [7]

Answer: h = 14

Step-by-step explanation:

7h-5(3h-8)-56 = -128

7h -15h+40-56 = -128

or, -8h-16= -128

or, -8h = -128 + 16

or, -8h = -112

or, 8h = 112

or, h = 112/8

so, h = 14
