Answer:
3.3
Step-by-step explanation:
Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
Based on a yearly rate (which is the norm) I give you my answer ..
Your principle is at 745$
Annual Rate 9%
For the first year your principle will grow by 67.05 $ if untouched (9%) up to 812.05 $
2nd year .. 9% of the 812.05 $ is 73.0845 $ .. So by the 2nd year you reach 885.1345 $
3rd year .. 79.662105 $ .. Total 964.796605 $
4th year .. 86.83169445 $ .. <u>Final</u><u> 4 Years </u><u>Total 1051.62829945 $</u>
Answer:
16000 = <u>2 × 2 × 2</u> ×<u> 2 × 2 × 2</u> × 2 × <u>5 × 5 × 5 </u>
16000 = 2³ × 2³ × 2 × 5³
if we mutiply 2³ × 2³ × 2 × 5³ by 2 × 2 , it becomes perfect cube , like it becomes 2³ × 2³ × 2³ × 5
therefore we have to multiply 2×2 = 4 with 16000 to make it perfect cube
<h2>
Answer with explanation:</h2>
Let 
be the population mean.
Null hypothesis : 
Alternative hypothesis : 
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic: 
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
