write an equation of a line that is parallel to y= -1/3x+4 and passes through (6,-3) . please provide the steps and explanation

murzikaleks [220]

Answer:

The answer is y = -1/3x - 1

Step-by-step explanation:

In order to find this we first must note that parallel lines have the same slope. Therefore, since the slope in the original line is -1/3, then we know the slope in our line will be the same. Now we can use point slope form with that slope and the given point to find the equation by solving for y.

y - y1 = m(x - x1)

y + 3 = -1/3(x - 6)

y + 3 = -1/3x + 2

y = -1/3x - 1

If Benito is selecting samples of five values from the table, which row will result in the greatest mean? Population Data Row 1

Vilka [71]

Answer:

4th row will result in the greatest mean.

Step-by-step explanation:

We are asked to find the row with greatest mean from our given rows.

We will use formula $\bar{x}=\frac{\Sigma x}{n}$ , where,

$\bar{x}=\text{Mean}$ ,

$\Sigma x=\text{Sum of all data values}$ ,

$n=\text{Number of data points in sample}$

Let us find mean of each row using above formula.

$\text{Mean of row 1}=\frac{4+2+2+3+3}{5}$

$\text{Mean of row 1}=\frac{14}{5}$

$\text{Mean of row 1}=2.8$

Therefore, mean of 1st row is 2.8.

$\text{Mean of row 2}=\frac{3+3+4+3+2}{5}$

$\text{Mean of row 2}=\frac{15}{5}$

$\text{Mean of row 2}=3$

Therefore, mean of 2nd row is 3.

$\text{Mean of row 3}=\frac{2+4+3+4+3}{5}$

$\text{Mean of row 3}=\frac{16}{5}$

$\text{Mean of row 3}=3.2$

Therefore, mean of 3rd row is 3.2.

$\text{Mean of row 4}=\frac{3+4+4+7+3}{5}$

$\text{Mean of row 4}=\frac{21}{5}$

$\text{Mean of row 4}=4.2$

Therefore, mean of 4th row is 4.2.

Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.

Im stuck on this savvas realize hw thats due today and i rlly need help

IceJOKER [234]

Answer:

3152 cm²

Step-by-step explanation:

Applying,

A = bh+(a+b+c)L................... Euqation 1

Where A = surface area of the triangular prism, a, b, c are the length of the three side of the triangule respectively, L = Length of the prism, h = height of the triangle.

From the question,

Given: a = 25 cm, c = 25 cm, b = 14 cm, h = 24 cm, L = 44 cm

Substitute these values into equation 1

A = 14×24+(25+25+14)44

A = 336+2816

A = 3152 cm²
