Answer:
0.2 = 20% probability that a student takes Spanish and engineering
Step-by-step explanation:
We solve this question treating the probabilities as Venn sets.
I am going to say that:
Event A: Student takes Spanish
Event B: Student takes Engineering.
35% of students take spainsh or engineering.
This means that [tex]P(A \cup B) = 0.35[/tex]
30% of students take Spanish.
This means that [tex]P(A) = 0.3[/tex]
25% of students take engineering.
This means that [tex]P(B) = 0.25[/tex]
What is the probability that a student takes Spanish and engineering?
This is [tex]P(A \cap B)[/tex].
These probabilities are related by the following formula:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
Replacing the values
[tex]P(A \cap B) = 0.3 + 0.25 - 0.35 = 0.2[/tex]
0.2 = 20% probability that a student takes Spanish and engineering
Find the length of the third side. If necessary, write in simplest radical form.

Answer:
4.2 ft
Step-by-step explanation:
Reference angle = 77°
Opposite side = DE = x
Hypotenuse = CD = 4.3 ft
Apply the trigonometric function of sine. Thus:
Sin 77 = opp/hyp
Sin 77 = x/4.3
Multiply both sides by 4.3
4.3 × sin 77 = x
x = 4.2 ft (nearest tenth)

Step-by-step explanation:
42=164, 73=499, 51= 251, 29=?
Given:
The reasoning problem is
42=164, 73=499, 51= 251, 29=?
To find:
The missing value.
Solution:
In the given reasoning problem, we need to square each digit then write them combinedly.
[tex]4^2=16[/tex]
[tex]2^2=4[/tex]
On combining these two, we get
[tex]42=164[/tex]
Similarly,
[tex]73=7^23^2=499[/tex]
[tex]51=5^21^2=251[/tex]
Using this pattern, we need write the square of 2 and 9 combinedly to find the value of 29.
[tex]29=2^29^2=481[/tex]
Therefore, the missing value is 481.

f(2) = 6+5
f(2) = 11
Answer:
11
Step-by-step explanation:
→ f(x) = 3x + 5
→ f(2) = 3(2) + 5
⇒ 6 + 5
⇒11

Answer:
885.18
Step-by-step explanation:
Base = 18x18=324
triangles = 1/2(18)height
To find the height, you could divide it in half and use the 30-60-90 rule or Pythagorean theorem.
9²+b²=18²
81+b²=324
b²=324-81
b²=243
b=√243
b=15.58
So each triangle is 1/2(18)(15.58845)=140.2961.
Four of them would be 561.1845.
Now add the base.
561.1845+324=885.1844

Answer:
c must be less than 10 but greater than 4.
Step-by-step explanation:
In order to solve this problem, you have to apply the triangle inequality theorem. This theorem is used to determine whether or not you can form a triangle. According to the theorem, the sum of the two sides must be greater than the longest side of the triangle.
For instance, a triangle has side lengths 4, 5, and 7.
Can you form a triangle with these values?
Well, let's see
Since 4 and 5 are values less than 7, you are going to be adding those numbers. 4 plus 5 is 9. 9 is greater than 7. This means that you can form a triangle with those numbers.
For this question, you are given a triangle that has the side lengths of 3 inches, 7 inches, and c inches. The question wants the range of values. Make c the shortest side and the longest side.
Let's start with longest first.
take 3 and 7
Add them and you will get 10.
10 is greater than c. or c<10.
For the shortest side make 7 the longest
3 plus c is less than 7
subtract 3 from both sides
then you get c is less than 4. or c<4.
So you have c<4 and c>10.
combine them to make a long inequality.
4<c<10.
That is your answer.

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the
point B. Find the coordinates of B.
Given :
M(6,5) is the mid-point of the straight line joining A(2 , 3) to the
point B.
To Find :
The coordinates of B.
Solution :
Let, coordinates of point B is ( h , k ) .
It is given that M is the mid - point of the straight line joining points A and B.
Coordinates of M is given by :
[tex]M = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\(6,5 ) = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\\dfrac{2+h}{2} = 6 \ , \ \dfrac{3+k}{2} = 5\\\\h = 10 \ ,\ k = 7[/tex]
Therefore, coordinates of point B is ( 10 , 7 ).

What’s 8367 divided by 7
Answer:
1195.28
Step-by-step explanation:
We have a division problem which is 8,367 ÷ 7.
When it comes to division, you always look at the first number that is being split equally by the second number.
Follow the steps of the division problem :
Find how many times 7 goes into 8 :
7 * 1 = 7
Subtract 7 from 8 :
8 - 7
1
We have 1 in our thousands place, move down the number next to 8 in 8367 which is 3, and see how many times 7 goes into that number :
13
7 * 1 = 7
Therefore 7 only goes in once, put 1 next to 1 on top of the division problem, subtract 7 from 13 :
13 - 7
6
Move the 6 down from 8367 and see how many times 7 goes into that :
7 * 9 = 63
Subtract 63 from 66 :
3
Put 9 next to the one, as for now we have 119, now bring down the last value in 8367 and see how many times 7 goes into that :
37
7 * 5
35
Subtract 37 - 35 :
2
Therefore, our answer is 1195.28 , 1195 Remainder 2
Step-by-step explanation: The result of 8367/7 is a non-terminating, repeating decimal. The repeating pattern above, 285714, is called repetend, and denoted overlined with a vinculum.
This notation in parentheses is also common: 8367/7 = 1195.(285714): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 8367 / 7 = 1195.285714… .
8367 divided by 7 in decimal = 1195.285714
8367 divided by 7 in fraction = 8367 divided 7
8367 divided by 7 in percentage = 119528.57142857%

Twenty-one is greater than the sum of fifteen and two times a number
Answer:
21> 2x+ 15
Step-by-step explanation:
The expression is 21 > 15+ 2x
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Twenty-one is greater than the sum of fifteen and two times a number
let the number be x.
two times a number = 2x
and, sum of fifteen and two times a number = 15 + 2x
So, Twenty-one is greater than the sum of fifteen and two times a number
21 > 15+ 2x
Hence, the expression is 21 > 15+ 2x.
