Answer:
The test statistic is -1.00
Step-by-step explanation:
Test statistic (Z) = (sample mean - population mean) ÷ sd/√n
sample mean = 38.8miles/gallon, population mean = 39miles/gallon, sd = 2.2miles/gallon, n = 120vans
Z = (38.8 - 39) ÷ 2.2/√120 = -0.2 ÷ 2.2/10.95 = -0.2 ÷ 0.20 = -1.00 (to 2 decimal places)
Answer:
G 0.48 hour
music 12% - tennis 10% = 2%
2% x 24 hrs = 0.48 h
−<span>2.8
</span>Okay so "0.9x-1.3=-3.1" x=-2
<span><span><span>0.9x</span>−1.3</span>=<span>−3.1
</span></span>add 1.3 to both sides
<span><span><span><span>0.9x</span>−1.3</span>+1.3</span>=<span><span>−3.1</span>+1.3
</span></span><span><span>0.9x</span>=<span>−1.8
</span></span>divide both sides by 0.9
<span><span><span>0.9x/</span>0.9</span>=<span><span>−1.8/</span><span>0.9
</span></span></span>x=<span>−2</span>
So if you plug in -2 into "x-0.8" you get −2.8
<span>=<span><span>−2</span>−0.8
</span></span><span>=<span><span>−2-</span><span>0.8
</span></span></span><span>=<span>−2.8
</span></span>Hope this helps.
Given:
Principal : $6,000
Interest Rate: 5%
Term : 8 years, compounded annually.
The term compounded annually is a hint that informs us to use the compounded interest formula instead of the simple interest formula.
Compounded interest formula is:
A = P(1 + r/n)^nt
where:
A = future value of loan or investment including the interest
P = principal
r = rate
n = the number of times the interest is compounded per year
t = the number of years the money is borrowed or invested
A = P (1 + r/n)^nt
A = 6,000 (1 + 0.05/1)¹ * ⁸
A = 6,000 (1.05)⁸
A = 6,000 (1.48)
A = 8,880
The total amount Ryan will pay after 8 years is $8,880.00
