Find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −3, 7) and
tia_tia [17]

Answer:

\vec{r}(t)=\left

In parametric form:

x=-1, y=\displaystyle\frac{1}{2}, z=4+t

Step-by-step explanation:

We first find the mid point:

\displaystyle\left(\frac{0+(-2)}{2},\frac{-3+4}{2},\frac{7+1}{2}\right)=\left(-1,\frac{1}{2},4\right)

Then, a vector parallel to the z-axis is:

\vec{v}=\left< 0,0,1 \right>

Then remember the equation of  a line passing through point (x_o,y_o,z_o) and parallel to the vector \vec{v}=\left is:

\vec{r}(t)=\left+t\left

So, in this problem we get:

\vec{r}(t)=\left+t\left

After combining the two vectors:

\vec{r}(t)=\left

In parametric form:

x=-1, y=\displaystyle\frac{1}{2}, z=4+t

Laura babysat 8 nights during the month of July. She earned $22, $30, $35, $25, $25, $20, and $27 for seven nights. How much did
Svet_ta [14]

Answer:

$28

Step-by-step explanation:

Given:

data = [22,30,35,25,25,20,27]

For eight night, the new list is:

new_data = [22,30,35,25,25,20,27,x]

Mean = 26.50

Mean Formula:

\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }

Therefore:

\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}

Multiply both sides by 8:

\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}

Solve for x:

\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}

Subtract 184 both sides:

\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}

Therefore, she will earn $28 in eighth night

The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
