Answer:

600

Step-by-step explanation:

We can solve the recursive formula for the previous term in terms of the present one:

a[n-1] = (a[n] +100)/1.5

Working backward, we find ...

a[4] = (a[5] +100)/1.5 = (2225 +100)/1.5 = 1550

a[3] = (1550 +100)/1.5 = 1100

a[2] = (1100 +100)/1.5 = 800

a[1] = (800 +100)/1.5 = 600

There were 600 daylilies on the farm after the first year.

A family drove a total of 5,300 miles.They drove 10 more miles in tj second half of the trip than the first half. How many did t

AVprozaik [17]

If they drove a total of 5,300 miles in 2 days, and on the second day they drove 10 more miles then the 1st day.

5,300 ÷ 2 = 2,650

they drove 10 miles less on the first day

2,650 - 10 = 2,640

They drove 2,640 miles on the first day.

Hope this helps. :)

The average monthly cell phone bill was reported to be $50.07 by the U.S. Wireless Industry. Random Sampling of a large cell pho

zalisa [80]

Answer:

The null and alternative hypotheses are:

$H_{0}:\mu= 50.07$

$H_{a}:\mu>50.07$

Under the null hypothesis, the test statistic is:

$t=\frac{\bar{x}-\mu}{\frac{s}{\sqrt{n}} }$

Where:

$\bar{x} = 52.86$ is the sample mean

$s=7.0132$ is the sample standard deviation

$n=10$ is the sample size

$\therefore t=\frac{52.86-50.07}{\frac{7.0132}{\sqrt{10}} }$

$=1.26$

Now, the right tailed t critical value at 0.05 significance level for df = n-1 = 10-1 = 9 is:

$t_{critical}=1.833$

Since the t statistic is less than the t critical value at 0.05 significance level, therefore,we fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that the average phone bill has increased.
