Answer:

34.13%

Step-by-step explanation:

Given the mean score is 450 and the standard deviation is 120.

-The probability of scoring between 450 and 570 can be calculated as below:

P(450

Hence, 34.13% of the scores lies between 450 and 570

The distance of the road junction form Timpson is given as 21.57 miles.

<h3>We have to solve this using the Pythagoras theorem method</h3>

We have AT = \sqrt{TN^{2}+AN^{2}  }

√60² + 12² = 12√26

∠TMG = LN = 90 degrees

Therefore we have the system

\frac{TM}{60} = \frac{22}{12\sqrt{26} }

When we cross multiply we would have to solve for TM

TM = 21.57 miles

Hence the distance of the road junction form Timpson is given as 21.57 miles.

Which formula gives the coordinates of the midpoint of the segment connecting points (a, b) and (c, d)?
Vesna [10]

( \frac{x1 + x2}{2} ) \:  \: ( \frac{y1 + y2}{2} )
You don't multiply both of them, it's a coordinate function. There's suppose to be a comma in between

Answer:

  • See below

Step-by-step explanation:

<h3>Q13</h3>

The greater the angle the greater the opposite side

<u>Sides in ascending order:</u>

  • AB = 17, AC = 18, BC = 21

<u>Angles in same order</u>

  • ∠C, ∠B, ∠A
<h3>Q14</h3>

<u>As above, sides in ascending order:</u>

  • AB = 15, AC = 16, BC = 17

<u>Angles in same order</u>

  • ∠C, ∠B, ∠A
<h3>Q15</h3>

<u>Exterior angle equals to sum of non-adjacent interior angles</u>

  • 142° = x + 66°
  • x = 142° - 66°
  • x = 76°
<h3>Q16</h3>

<u>Same subject and isosceles triangle:</u>

  • x + x = 158°
  • 2x = 158°
  • x = 79°
<h3>Q17</h3>

<u>Same subject</u>

  • m∠QSR = m∠QPS + m∠PQS
  • 2x = x + m∠PQS
  • m∠PQS = 2x - x
  • m∠PQS = x

ΔPQS has two angles with the measure of x, hence their opposite sides are congruent and the triangle is isosceles
