Label the diagram correctly and then calculate the height of the wall (if necessary, round your answer to 2 decimal places. SHOW ALL YOUR WORK. on label of drawing.
Answers
Answer:
18 feetStep-by-step explanation:
As per the diagram, the triangles on the left and right are similar.
The ratio of corresponding sides is equal:
27/9 = x/6x = 6*3x = 18The height of the wall is 18 feet
Answer:
[tex]\Huge\mathtt{\underline\pink {Answer}}[/tex]
[tex] \tt \frac{27}{9} = \frac{x}{6} [/tex]
[tex] \tt \: x = 6 \times 3 = 18[/tex]
So, height is 18 feet

Answer: (a + 2)(a - 2) which is the first answer choice
=========================================================
Explanation:
Use the difference of squares factoring rule which is x^2 - y^2 = (x+y)(x-y)
In this case, x = a and y = 2
x^2 - y^2 = (x+y)(x-y)
a^2 - 2^2 = (a+2)(a-2)
a^2 - 4 = (a+2)(a-2)

A college has a total of 107 teachers 23 more female teachers than male teachers
What proportion of the teachers are female? use n as the unknown
Answers
Answer:
Female reachers = 65
Step-by-step explanation:
Given that,
Total teachers in a college = 107
Let there are n male teachers.
Female reachers = n+23
ATQ,
n+n+23 = 107
2n = 107-23
2n = 84
n = 42
Female reachers = 42+23
= 65
Hence, there are 65 female teachers.

Answer:
a) This expression is simply the average of both of their hours for a full year.
b) Honestly, I'm not sure, but mathematically, its [tex]\frac{Beth's -hours}{Arjun's-hours}[/tex], so the hours cancel out and you get the ratio of their yearly hours? Idek
c) a/12 would be the number of hours Arjun worked per month since there are 12 months in a year.
d) This one is a difference between Arjun's hourly wage to Beth's hourly wage. So, it represents how much more Arjun would have made (Arjun's hourly wage) in comparison to Beth, or vice versa (depending on who worked more hours).
c) Similar to a), this is an average of their yearly income.

According to the Stack Overflow Developers Survey of 20184, 25.8% of developers are students.The probability that a developer is a woman given that the developer is a student is 7.4%,and the probability that a developer is a woman given that the developer is not a student is76.4%. If we encounter a woman developer, what is the probability that she is a student
Answers
Answer:
0.0326 = 3.26% probability that she is a student.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Woman developer
Event B: Student
Probability that the developer is a woman:
7.4% of 25.8%(students).
76.4% of 100 - 25.8 = 74.2%(not students). So
[tex]P(A) = 0.074*0.258 + 0.764*0.742 = 0.58598[/tex]
Student and woman developer.
7.4% of 25.8%(students), so
[tex]P(A \cap B) = 0.074*0.258 = 0.019092[/tex]
If we encounter a woman developer, what is the probability that she is a student
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.019092}{0.58598} = 0.0326[/tex]
0.0326 = 3.26% probability that she is a student.
