The given is: <span>−2(x+1)≥3x+8
The first step is getting rid of the brackets using the distributive property.
The second and third steps is isolating the term containing the x on one side of the inequality using addition or subtraction property of order
The last step is getting rid of the coefficient of the x using the multiplication or division property of order.
So, the correct order of choices is:
1- </span>distributive property.
2- addition or subtraction property of order
3- addition or subtraction property of order
4- multiplication or division property of order.<span>

70 = 100 - 2•15 is 2 s.d.'s below the mean.
130 = 100 + 2•15 is 2 s.d.'s above the mean.
By the empirical rule,
Pr [70 ≤ X ≤ 130] = Pr [-2 ≤ Z ≤ 2] ≈ 95%
(where Z is normally distributed with mean 0 and s.d. 1)
Answer:
9) a) Nu 280
b) Nu 1120
10) 20%
11) a) Nu 2080
b) Nu 10080
Step-by-step explanation:
9) a) 1400 * .80 = 1120 1120-1400=280
b) 1400*.80 = 1120
10) 900/750=1.20 1.20-1=0.20 0.20*100= 20%
11) a) I = 8000*18*.07 = 10080 10080-8000=2080
b) I = 8000*18*.07 = 10080
If I assume that you merely want the simple interest, then:
i = <span>$500 (0.12) (3/2) = 90 dollars simple interest was earned.
If you want the accrued amount, with compounding twice yearly, then
A = $500 (1+0.12/2)^3 = $595.51. In this case the interest earned is $95.51.</span>
