Answer:

D.130°

Step-by-step explanation:

An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.

-Given that AC and BC are diameters, then $\angle AOB =\angle DOC$ since they are alternate angles.

$\angle AOB =\angle dOC=180\textdegree\\\\3x-70=x+10\\\\x=40\textdegree$

#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:

$(3x-70)+m\angle BC=180\\\\M\angle BC=180+70-3\times 40\\\\=130\textdegree$

Hence, mBC=130°

A farmer would like to estimate the mean amount of

Soloha48 [4]

Answer:

0.765

Step-by-step explanation:

The dot plot shows the data

x= 20,21,22,23,24,24,25,25,25,26,26,27,28,29,31

The mean x`= ∑x/n =20+21,+22,+23,+24,+24,+25,+25,+25+,26+,26+,27+,28+,29+,31/15= 376/15

=25.067

where n is the sample size= 15

The standard deviation is σ=2.96

( using calculator)

The standard error is calculated as

SE= σ/√n

SE= 2.96/√15

SE= 0.765
