Find the other endpoint of the line segment if:

Vesna [10]

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>

Help pls I don't know how to explain it

a_sh-v [17]

Answer: C

Step-by-step explanation:

On the left side, there are 2 triangles and 6 2's, so this equals 2x+12.

On the right side, there are 4 triangles and 2 2's, so this equals 4x+4.

Meaning 2x+12=4x+4.

12=2x+4

2x=8.

g The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 cus

vagabundo [1.1K]

Answer:

The right solution is "0.196".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1 \ minute$

Sample size,

$n=100$

Confidence level,

$c=95$ %

$=0.95$

Now,

For $\alpha=1-c$

$= 1-0.95$

$=0.05$

then,

$Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }$

$=Z_{0.025}$

$=1.96$

The margin or error will be:

⇒ $E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })$

On substituting the values, we get

= $1.96(\frac{1}{\sqrt{100} })$

= $1.96\times \frac{1}{10}$

= $0.196$
