Answer:
P(Hispanic or Bilingual) = 0.429.
Step-by-step explanation:
This question is solved treating these events as Venn probabilities.
I am going to say that:
Event A: Hispanic
Event B: Bilingual
Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:
This means that:
[tex]P(A) = \frac{4}{14}, P(B) = \frac{5}{14}, P(A \cap B) = \frac{3}{14}[/tex]
What is the probability that teacher is Hispanic or bilingual?
This is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the values that the exercise gives us:
[tex]P(A \cup B) = \frac{4}{14} + \frac{5}{14} - \frac{3}{14} = \frac{4 + 5 - 3}{14} = \frac{6}{14} = 0.429[/tex]
So
P(Hispanic or Bilingual) = 0.429.

Answer:
Which of the following statements is INCORRECT?
please help me this assignment is overdue
Answer:
B. DE = 58
Step-by-step explanation:
The base angles (<F and <E) of the ∆DEF are congruent/equal. This means that ∆DEF is an isosceles triangle.
This implies that, the two sides (DF and DE) that are opposite to the base angles are congruent/equal.
DE = 40 (given) => option B is INCORRECT
Therefore:
8x - 24 = 40
Solve for x
8x - 24 + 24 = 40 + 24
8x = 64
8x/8 = 64/8
x = 8 (option C is CORRECT)
Let's find DF and FE:
DF = 8x - 24
Plug in the value of x
DF = 8(8) - 24
DF = 64 - 24
DF = 40 (Option D is CORRECT)
FE = 6x + 10
FE = 6(8) + 10
FE = 48 + 10
FE = 58 (Option A is CORRECT)
The only incorrect statement is:
B. DE = 58

Step-by-step explanation:
3(x+2) simplified is equal to (3)x+(3)2 which is simplified to 3x+6.
a. 3x+2 is not the same as 3x+6 so it is false.
b. 3(2+x) is simplified to (3)2+3(x) which is simplified to 6+3x or 3x+6 which is equal to 3x+6 so it is true.
c. 3x+2x is simplified to 5x which is not equal to 3x+6 so it is false.
d. x+2x+2+4 is simplified to 3x+6 which is equal to 3x+6 so it is true.
e. x+x+x+1+1+1+1+1+1 is simplified to 3x+6 which is equal to 3x+6 so it is true.

Answer:
X = 10.7
Step-by-step explanation:
25^2 - 16^2 = 369 which squared is approximately 19.2. We need X which is the smaller side so we minus 22^2 from 19.2^2 which is 115.36 which is squared to 10.7

Answer:
Sequence: 13, 20, 27
Rule: Tn = 7n + 6
Step-by-step explanation:
The 3 other numbers that can form an arithmetic progression is 13, 20, 27...
The nth term of an arithmetic progression is expressed as;
Tn = a + (n-1)d
a is the first term = 13
n is the number of terms
d is the common difference = 20 - 13 = 27 - 20
d = 7
Substitute
Tn = 13 + (n-1)(7)
Tn = 13 + 7n - 7
Tn = 7n+13-7
Tn = 7n + 6
This gives the required rule
Beth measured a piece of wood to be 12.7 centimeters in length. Knowing that there are about 2.54 centimeters in an inch, she can use the formula below to find n , the length of the wood, in inches. 2.54n=12.7 What value of n will make this equation true?
Answer:
[tex]n = 5[/tex]
Step-by-step explanation:
Given
[tex]2.54n = 12.7[/tex]
Required
Find n
We have:
[tex]2.54n = 12.7[/tex]
Divide both sided by 2.54
[tex]\frac{2.54n}{2.54} = \frac{12.7}{2.54}[/tex]
[tex]n = \frac{12.7}{2.54}[/tex]
[tex]n = 5[/tex]

Using the tangent ratio, the value of x, to the nearest tenth, is: 5.5.
How to Use the Tangent Ratio to Solve a Triangle?Given a right triangle with a missing length, x, we have the following:
∅ = 70°
Opposite side length = 15
Adjacent side length = x
The tangent ratio to be applied is:
Tan ∅ = opp/adj
Plug in the values
Tan 70 = 15/x
x(tan 70) = 15
x = 15/tan 70
x ≈ 5.5

Answer:
x = 20
Step-by-step explanation:
Corresponding sides are proportional:
x/15 = 24/18
x = 15(24/18) = 15(4/3)
x = 20
Answer:
Solution :-According to the property of corresponding sides
x1/x2 = y1/y2
x/15 = 24/18
x/15 = 4/3
x = 4 × 15/3
x = 4 × 5

Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a = [tex]\sqrt{24}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]
2) b² + 5² = 6²
b² = 36-25
b = [tex]\sqrt{11}[/tex]
Base = 2[tex]\sqrt{6}[/tex] + [tex]\sqrt{11}[/tex]
A = 1/2 x 5· (2[tex]\sqrt{6}[/tex] + [tex]\sqrt{11}[/tex])
A = 2.5 · (2[tex]\sqrt{6}[/tex] + [tex]\sqrt{11}[/tex])
A = 2.5(8.2)
