1200,000(1+.1)=(the answer) sorry I don't have a calculator with me.
Answer:
z = 2.6
Step-by-step explanation:
<u>Use the formula for z-score</u>
This tells us that this person's score of 210 places them 2.6 standard deviations above the mean
X² + 6x -12 = 0
x = <u>-(6) +/- √((6)² - 4(1)(-12))</u>
2(1)
x = <u>-6 +/- √(36 + 48)</u>
2
x = <u>-6 +/- √(84)
</u> 2<u>
</u>x = <u>-6 +/- 2√(21)
</u> 2<u>
</u>x = -3 <u>+</u> √(21)
x = -3 + √(21) x = -3 - √(21)
Answer:
D. x to the power of nine
Step-by-step explanation:
The applicable rule of exponents is ...
(x^a)^b = x^(ab)
You have a=3/2, b=6, so ab = 3/2·6 = 9.
(x^(3/2))^6 = x^(3/2·6) = x^9
Answer:
The total amount of money Alex spends on 5 DVD = $ 35.
Step-by-step explanation:
Total number of DVD purchased by Alex = 5
The cost of each DVD = $9
So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)
= 5 x ( $ 9) = $ 45
Now , the discount if 1 DVD = $ 2
So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)
= 5 x ($ 2) = $ 10
⇒ The total amount Alex spends
= Total cost of 5 DVD - Discount on 5 DVD
= $ 45 - $ 10 = $ 35
Hence, the total amount of money Alex spends on 5 DVD = $ 35.
