A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. The mean is found to be 10.3
user100 [1]

Answer:

Confidence interval for the true mean number of reproductions per hour for the bacteria is (10.1,10.5).

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 10.3

Population standard deviation, σ = 2.1

Sample size, n = 728

Alpha, α = 0.01

Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.01} = \pm 2.58

10.3 \pm 2.58(\frac{2.1}{\sqrt{728}} ) = 10.3 \pm 0.2008 = (10.0992,10.5008) \approx (10.1,10.5)

What is m CD ?<br> Plzz help
pickupchik [31]

Given:

Arc(AB) = 78 degrees

Measure of angle CMD = 106 degrees

To find:

The measure of arc CD.

Solution:

Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.

Using secant intersection theorem, we get

m\angle CMD=\dfrac{1}{2}(Arc(AB)+Arc(CD))

106^\circ=\dfrac{1}{2}(78^\circ+Arc(CD))

Multiply both sides by 2.

212^\circ=78^\circ+Arc(CD)

212^\circ-78^\circ=Arc(CD)

134^\circ=Arc(CD)

Therefore, the measure of arc CD is 134 degrees and the correct option is C.

Three angles are labeled below with arcs the smallest angle is 3/8 as large as the 160 angle find the value of angle s
Andrej [43]
S is equal to 140.  This is because the smallest angle is 60 degrees. The biggest angle is 160 degrees. And 60 + 160 = 220. A circle is 360 degrees. 360 minus 220 equals 140.
