A firm offers routine physical examinations as part of a health service program for its employees. The exams showed that 14% of the employees needed corrective shoes, 21% needed major dental work, and 3% needed both corrective shoes and major dental work. What is the probability that an employee selected at random will need either corrective shoes or major dental work
Answer:
0.32 = 32% probability that an employee selected at random will need either corrective shoes or major dental work.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Event A: Needing corrective shoes.
Event B: Needing major dental work.
14% of the employees needed corrective shoes
This means that [tex]P(A) = 0.14[/tex]
21% needed major dental work
This means that [tex]P(B) = 0.21[/tex]
3% needed both corrective shoes and major dental work.
This means that [tex]P(A \cap B) = 0.03[/tex]
What is the probability that an employee selected at random will need either corrective shoes or major dental work?
This is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So, from the values given by the exercise:
[tex]P(A \cup B) = 0.14 + 0.21 - 0.03 = 0.32[/tex]
0.32 = 32% probability that an employee selected at random will need either corrective shoes or major dental work.

From the above explanation, the option B statement is not correct.
From the given options we need to identify which statement is not correct.
What is an obtuse angle?An obtuse angle is any angle greater than 90° and less than 180°.
From option A:
100° angle is an obtuse angle, because which is greater than 90° and less than 180°.
From option B:
175° angle is a reflex angle because it is greater than 180° and less than 360°.
From option C:
Less than 90° lies in I quadrant, more than 90° and less than 180° lies in II quadrant and more than 180° and less than 270° lies in III quadrant.
From option D:
An 85° angle is an acute angle because it is greater than 0° and less than 90°.
From the above explanation, the option B statement is not correct.

Hana is putting in a tile floor she needs to determine the angles that should be cut in the tires to fit in the corner that angle in the corner measures 90° one piece of the tire will have a measure of 38 degrees write an equation and use it to determine the measure of the unknown angle
Answer:
x = 52°
Step-by-step explanation:
I have attached an image to depict the given angles.
From the attached image, we can see that the unknown angle is x°.
Thus, since that corner is 90°, then;
x + 38 = 90
Subtract 38 from both sides to get;
x = 90 - 38
x = 52°
1) Find the missing angle.
31°
949
? + 31° + 94° = 180°
? + 125° = 180°
? = 180° - 125°
? = 55°
Answer: 52°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
So to work out what the missing angle is, you would have to add 34 and 94 together.
34+94=128
Then you would have to take 128 away from 180.
180-128=52°
Hope this helps :)

Meghan flipped a quarter and rolled a standard six-sided die.
The probability that the coin landed on heads and the die landed on an even number is __%.
Answer:
25%
Step-by-step explanation:
right on the test
The required probability of the coin landed on heads and the die landed on an even number is 25%.
Given,
Meghan flipped a quarter and rolled a standard six-sided die. The probability that the coin landed on heads and the die landed on an even number is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Sample space of coin = { head, tail } = 2
Sample space for die = { 1, 2, 3, 4, 5, 6 } = 6
favorable outcome for coin = head = 1
favorable outcome for the die to landed on even number = {2, 4, 6} = 3
Now the probability that the coin landed on heads and the die landed on an even number is,
P = probability of head-on coin * probability of the even number on die
P = 1/2*3/6
P = 1/4
P = 0.25 and 25%
Thus, the required probability of the coin landed on heads and the die landed on an even number is 25%.

The perimeter of a square is 20. What is the length of one of the diagonals of the square? Show work or explain how you obtained your answer
Answer:
The perimeter of a square is 20
if length of the square is x
perimeter of a square = x + x+ x + x = 4x = 20
4x = 20
x= 20/4
x = 5
Let get the length of one of the diagonal is y
According to the Pythagoras low,
y^2 = x^2 + x^2
y^2 = 5^2 + 5^2
