Answer:
B
Step-by-step explanation:
The answer is b, because if 5 and 10 are in the middle, you add them (15) then divide by 2, to get 7.5
Answer:False
Step-by-step explanation:
<h3><u>
Answer:</u></h3>
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
<h3><u>
Step-by-step explanation:</u></h3>
Let A denote the event of rolling a number less than 5 in a six-sided die.
Now, we know that the Total outcomes are: 6
since, the sample space is given as: {1,2,3,4,5,6}
Also Number of favorable outcomes are: 4
since the numbers which are less than 5 are {1,2,3,4}
Now we have to find:
where P denotes the probability of an event and 
denote the complement of event A.
We know that:
Now,
Hence,
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
<span>Let ∠ ADC = 2β
Ac and BD are perpendicular bisectors of each other ⇒⇒ (Given information)
∴ BD </span><span>bisects the angle ADC
∴ ∠ADE = 0.5 ∠ADC = β
And in ΔADE:
∵∠DEA = 90° ⇒⇒⇒ from the given information
∴∠DAE = 90° - β
And AC bisects ∠DAB </span><span><span>⇒⇒⇒ from the given information
</span>∴∠EAB = ∠DAE = 90° - β</span>
Answer:
OC = 10.07 CM
BC = 9.73 cm
area triangle OAB = 97.98 cm^2
area of sector OADB = 150.05 cm^2
% of diagram that is shaded = 65%
Step-by-step explanation:
cos 44 = OC/14
0.71934(14) = OC = 10.07
sin 44 = BC/14
0.6947(14) = BC = 9.73
area of sector OADB = (88/380)(Pi)14^2) =150.05
area triangle OAB = (OC)(BC)(0.5)(2) = 97.98
% of diagram shaded = 97.98/150.05 = 0.65 = 65%
