Answer:

Step-by-step explanation:

Coordinates of midpoint are ( $\frac{x_{1} +x_{2} }{2}$ , $\frac{y_{1} +y_{2} }{2}$ )

( - 5 + x ) / 2 = - 10 ⇒ x = - 15

( 4 + y ) / 2 = - 6 ⇒ y = - 16

<em>( - 15, - 16 )</em>

<h3>Answer: Total price of all 5 cars = $35000.</h3>

Step-by-step explanation:

We are given total number of cars = 5 cars.

The mean of all of five cars = $7000.

Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.

<em>Total price = Mean × Total number of cars.</em>

According to problem, mean is 7000 and total number of cars is 5.

<h3>Therefore, Total price of all 5 cars = 7000 × 5 = $35000.</h3>

Please help asap im super confused<br> Which is the equation for BC?

Aloiza [94]

Points on BC:
(-5, 5) and (0,1)
Slope = (5-1)/(-5-0)
Slope = -4/5

y = mx + c
y = -4/5x + c

at point (0,1)
1 = -4/5(0) + c
c = 1

y = -4/5x + 1
5y = -4x + 5
4x + 5y = 5 (Answer D)

Sam and Harry are family. Sam is currently is three times Harry's age. Sam's age is also 10 more than twice Henry's age. What ar

kramer

Answer:

<em>Sam is 30 years old, and Harry is 10 years old.</em>

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, $x=3y$ ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, $x=2y+10$ ---------------2

Subtracting 2 from 1, we get

$\Rightarrow x-x=3y-2y-10$

$\Rightarrow 0=y-10$

$\Rightarrow y=10$

putting this in equation 1,

$x=3(10)=30$

Therefore, Sam is 30 years old, and Harry is 10 years old.

For the data set 6, 5, 10, 11, 13, the mean, x, is 9. What is the standard deviation?

Salsk061 [2.6K]

Answer:

your answer will be 3.4

Step-by-step explanation:

n=number of terms

{6,5,10,11,13}=5

also ∑(x-x)^2=46

$S=\sqrt{\frac{1}{5-1} *46} =$

$\sqrt{\frac{46}{4} }=\sqrt{11.5} \\\\S=3.4$

hope it helps
