Answer:
Step-by-step explanation:
Use this formulae.(b square = a square + c square - 2acsine B )
The multiplier of her original salary to her reduced salary is ...
(1 - 10%) = 0.90
The multiplier of her reduced salary after her raise is ...
(1 +30%) = 1.30
The multiplier of her raised salary from her original salary is ...
(0.90)(1.30) = 1.17 = (1 +17%)
Her salary after the 17% raise is ...
1.17·1500/mo = $1755/mo
x=125
∠PAT=180° - ∠ATP - ∠APT
∠PAT=180 - 3x - 3 -4x -4= (173 - 7x)°
3x + 3 + 4x + 4 + 173-7x = 180
⇔x = 125
Let's first arrange it in ascending order :
340, 480, <u>560</u>, 680, 700
<u>560</u> is clearly the median.
Now add an additional score of 700 to the data :
340, 480, <u>560, 680</u>, 700 ,700
<u>560, 680</u> is separating both halves but is not the median
Median = (560+680)/2
= 1240 / 2
Median = 620
