What is the arc measure of DBC in degrees?

Mathematics

<h2>Answer:</h2><h2 />

In this context:

\boxed{\angle DBC=x=60^{\circ}}

<h2>Explanation:</h2>

Hello! Remember to write complete questions in order to get good and exact answers. Here the figure is missing so I'll assume the arc measure of DBC is given in radian and you want it in degrees. By definition, an arc's measure is <em>the measure of its central angle </em>being a central angle an <em>angle between two radii in a circle</em>. Suppose that angle measures:

\angle DBC=\frac{\pi}{3}\ radian \\ \\ \\ So, \ by \ rule \ of \ three: \\\\ \\ \pi \ radian \rightarrow 180 \ degrees \\ \\ \pi/3 \ radian \rightarrow x \ degrees \\ \\ \\ x =\frac{180\pi}{3\pi}=60^{\circ} \\ \\ \\ Finally: \\ \\ \boxed{\angle DBC=x=60^{\circ}}

krok68 [10]

Answer:

C. 0.98

Step-by-step explanation:

Let x be the mean of Company A and B annual profit and x/2 and y are standard deviation of Company A and B annual profit.

P(B<0) = 0.9*P(A<0)

P(Z<(0-x)/y) = 0.9*P(Z<(0-x)/(x/2))

P(Z<-x/y) = 0.9*P(Z<-2)

P(Z<-x/y) = 0.0205

x/y =2.04

Or y/x = 1 /2.05

y/x =0.49

Ratio of the standard deviation of company B annual profit to the standard deviation of company A annual profit =y/(x/2)

= 2*(y/x)

= 2*0.49

= 0.98

Pedro is doing math exercises from a software program he recently purchased. In the program, you have to get at least 70% of the
Nookie1986 [14]
The inequality would be
0.75q ≥ 0.70(q+1)

q is defined as the number of questions he answers after the first one.  We are told he gets 75% of those correct; 75%=75/100=0.75.  This gives us 0.75q.

Since he gains proficiency on the exercises, the total number he gets correct has to be at least 70%.  This means the inequality would have the symbol greater than or equal to, as it cannot be less and have him gain proficiency.

He has already answered 1 question and answers q more; this gives us a total of q+1.  Since he gains proficiency, the cutoff was 70%; 70%=70/100=0.70.  This gives us the expression 0.70(q+1).

Our total inequality would then be 0.75q ≥ 0.70(q+1)
