Call 911 then but the answer is $4 because 12/3 is 4
Answer:
1. 9x^2-24xy16y^2
2.
3.9y^2-246y+1681
4. 18x^2+54x-44
Step-by-step explanation:
1. (3x)^2-2*3x*4y+(4y)^2
9x^2-2*3x4y+(4y)^2
9x^2-24xy+(4y)^2
9x^2-24xy+16y^2
Ans: 9x^2-24xy+16y^2 the (*) are times
2. 912+31-20=923
ANS: 13*71
3. 1681-246y+9y^2
9y^2-246y+1681
ANS : 9y^2-246y+1681
4. 3x*(9*2+6x+4)-2(9*2+6x+4)
54x+18^2+12x-2(9*2+6x+4)
54x+18x^2+12x-36-12x-8
54x+18^2+12x-36-12x-8
54x+18x^2-36-8
18x^2+54x-36-8
18x^2+54x-44
Ans: 18x^2+54x-44
5. 3x*3x-3x*4+5*3x-5*4
9x^2-3x*4+5*3x-5*4
9x^2-12x+5*3x-5*4
9x^2-12x+15x-5*4
9x^2-12x+15x-20
ANS: 9x^2+3x-20
6. (31+2)(912-61+4)=28215
ANS : 3^3*5*11*19
7. 9.12-2414+1672
912/100-2414+1672
2^4*3*19/2^2*5^2 -2414+1672
2^4-2*3*19/5^2 -2414+1672
2^2*3*19/5^2 -742
(2^2*3*19)-5^2)742/5^2
(4*3*19)-25*742/5^2
228-18550/5^2
18322/5^2
8. 2713-8
2705
ANS: 5*541
Answer: 1.25 square feet
This converts to the improper fraction 5/4
===========================================================
Explanation:
The area of the triangle on the left is base*height/2 = 0.5*2/2 = 0.5 square feet. Note that 1/2 = 0.5
The area of the triangle on the right side is base*height/2 = 0.2*3/2 = 0.75 square feet. This converts to the fraction 3/4
Add up the two results: 0.5+0.75 = 1.25 square feet
-----------
If you need the answer as an improper fraction, then,
1.25 = 1 + 0.25
1.25 = 1 + 1/4
1.25 = 4/4 + 1/4
1.25 = (4+1)/4
1.25 = 5/4
Answer:
mean = 70000
SD = 15239
X= 95000
Z = (X-mean)/ SD
= (95000-70000)/15239
= 1.64
Now from Z-Table
% of employees = 100(1-.9495) = 5.02%

recall again, sin²(θ) + cos²(θ) = 1.
