A 30-gram sample of bacteria has some unknown disease that is killing the bacteria. The amount of bacteria is measured each day
Firdavs [7]
For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease factor
 t: time
 Substituting values:
 y = 30 * (b) ^ t
 To calculate t we use a point in the table.
 We have:
 (t, y) = (1, 28.5)
 Substituting:
 28.5 = 30 * (b) ^ 1
 b = 28.5 / 30
 b = 0.95
 Answer:
 
a. Decay factor is 0.95

From a random sample of 41 teens, it is found that on average they spend 43.1 hours each week online with a population standard
Nadusha1986 [10]

Answer:

Step-by-step explanation:

We want to determine a 90% confidence interval for the mean amount of time that teens spend online each week.

Number of sample, n = 41

Mean, u = 43.1 hours

Standard deviation, s = 5.91 hours

For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

43.1 ± 1.645 × 5.91/√41

= 43.1 ± 1.645 × 0.923

= 43.1 ± 1.52

The lower end of the confidence interval is 43.1 - 1.52 =41.58

The upper end of the confidence interval is 43.1 + 1.52 =44.62

Therefore, with 90% confidence interval, the mean amount of time that teens spend online each week is between 41.58 and 44.62

In which quadrant does O lie if the following statements are true:<br> cos 0 &lt; 0 and cscO &gt; 0
Olin [163]

Answer:

2nd quadrant.

Step-by-step explanation:

\text{Given that,}~ \cos \theta < 0~ \text{and}~ \csc \theta > 0.}\\\\\text{So,}~\cos \theta ~ \text{is negative and}~ \csc \theta ~ \text{is positive.}\\\\\text{In Quadrant II, all other ratios are negative except}~ \sin \theta ~ \text{ and}~ \csc \theta.\\\\\text{Hence, the angle lies in the 2nd quadrant.}~
