This is probably wrong but my guess is 13 so maybe verify it but that’s my best!
Answer:
78.64 feet
Step-by-step explanation:
Refer the attached figure
Height of the tall building = AC
The angle of depression from the top of one building to the foot of a building across the street is 53°. i.e.∠ADC = 53°
The angle of depression to the top of the same building is 19°.i.e.∠AEB = 19°
Height of small building = ED
The two buildings are 80 feet apart i.e. CD =BE= 80 feet
In ΔABC
In ΔABE
AC - AB = BC
106.16-27.52=BC
78.64=BC
So, BC = ED = 78.64 feet
Hence the height of the shorter building is 78.64 feet
Answer: The probability that no women are chosen to be in the committee is 2/5 or 0.40.
Step-by-step explanation:
We have two positions, and we have 6 options for those positions, 3 are men, and 3 are women.
If we want to see the probability where no women are chosen, then this means that in the first selection a man is chosen.
If all the 6 nominees have the same probability of being chosen, then the probability that in the first selection a man is chosen is equal to the number of men divided the total number of nominees, this is:
p1 = 3/6 = 1/2.
Now the same happens for the second selection, but now we have 5 total nominees and 2 are men, so the probability now is:
p2 = 2/5
And the joint probability will be the product of the individual probabilities, then we have:
P = p1*p2 = (1/2)*(2/5) = 2/5.
The probability that no women are chosen to be in the committee is 2/5 or 0.40.
The answer is c. are double the arc that they subtend.
