14-6y=44
-14 Both sides
-6y=30
÷-6 both sides
Y=-5

Y=5
Ok so first you minus 14 from 44
44-14
then divide the answer 30 by 6
30/6
and you get your answer 5

When it comes to airport security, when in come to passengers going through security and being flagged as a risk, what kind of p

romanna [79]

Answer:

Correct option: (A) Someone with dangerous material that pass through security.

Step-by-step explanation:

Before boarding a flight every person has to pass through airport security.

The security checks every person thoroughly before they are confirmed as safe to go.

The security checks every person for some harmful substances like, weapons, chemical,etc.

If a person is caught with any of these objects the security stops them from boarding the plane.

So if a person is flagged as a risk by the airport security, he/she should have been carrying any kind of harmful substances.

Thus, the correct option is (A).

PQ and QR are 2 sides of a regular 12-sided polygon. PR is a diagonal of the polygon. Work out the size of angle PRQ. You must s

dmitriy555 [2]

Answer:

15°

Step-by-step explanation:

A regular polygon is a polygon in which all the sides and angles of the polygon are equal to each other.

A regular 12-sided polygon is a polygon with 12 equal sides and angles.

The sum of interior angles of a polygon is given as:

sum = (2n - 4)90; where n is the number of sides of the polygon

For a 12 sided polygon:

Sum of interior angles = (2 * 12 - 4)90 = (24 - 4)90 = 20 * 90 = 1800°

Therefore since all the angles are equal, each angle = 1800° / 12 = 150°

Therefore in the question, ∠PQR = 150° (angle of a 12 sided polygon), ∠PRQ = ∠QPR = x

Therefore in triangle PQR:

∠PQR + ∠PRQ + ∠QPR = 180°

150 + x + x = 180

150 + 2x = 180

2x = 30

x = 15°

∠PRQ = 15°

Answer:

Hello your question is incomplete attached below is the complete question

answer : 1596 ± 2.861 $\sqrt{\frac{1580^2 }{20 } +\frac{2350^2 }{20 } }$ ------ ( A )

Step-by-step explanation:

I will use excel function to resolve this question

<u>Determine the 99% confidence of interval for the difference in mean number of steps by all people</u>

∝ = 0.01

critical value ( t ) = 2.861 ( = TINV ( 0.01, 19 )

Given that :

S1 = 1580

S2 = 2350

n1 = 20

n2 = 20

Difference in mean = x1 - x2 = 1596

Margin of Error = t * $\sqrt{\frac{S^2_{1} }{n_{1} } +\frac{s^2_{2} }{n_{2} } }$

∴ 99% confidence of interval

= 1596 ± 2.861 $\sqrt{\frac{1580^2 }{20 } +\frac{2350^2 }{20 } }$ ------
