Answer:
5/12
Step-by-step explanation:
Here, we want to select the probability that the selected student is a sophomore given that he is a boy
In this case;
P(B) = P(boy)
P(A) = P(sophomore)
What we know is that the probability for any section is simply the number of that section divided by the total number of students which is 12 + 18 = 30
From the table;
P(B) = 12/30
P(An B) = 5/30
So;
P(A|B) = 5/30 divided by 12/30
= 5/30 * 30/12 = 5/12
5. Find CD.
9x-15=7x-1
I really need help with this one.
Answer:
CD = 48
Step-by-step explanation:
Find the value of x using the two equations
9x - 15 = 7x - 1
9(7) - 15 = 7(7) - 1
63 - 15 = 49 - 1
48 = 48
Answer: x = 7
Then get the result of both equations
CD = 48
The length of CD is 48 units.
What is Isosceles Triangle?Isosceles triangles are those triangles which has the length of two sides or angles are equal to each other.
Given triangle ABC is an isosceles triangle since the length of sides AB and BC are given to be equal.
BD is the altitude of the triangle from the vertex B.
We know that, altitude of an isosceles triangle from the non equal angle bisect the opposite side, which is base.
So, AC is bisected at D.
AD = CD
9x - 15 = 7x - 1
Solving,
9x - 7x = -1 + 15
2x = 14
x = 7
Length of CD = 7x - 1 = 49 - 1 = 48
Hence 48 units is the length of CD.

Brian says that ABCD is a right triangle. Is he correct? (Round your answer to the nearest whole number) Explain.
17 m
21.7 m
С
D 13.5 m
21.7²=17²+13.5²
21.7²=289+182.25
21.7²=471.25
21.7=√471.25
21.7=21.7
22(to the nearest whole number)
Answer: Yes, it is a right triangle
But only if you rounded everything to the nearest whole number.
Otherwise, it's a bit off (but fairly close).
==========================================================
Explanation:
If that was a right triangle, then a^2+b^2 = c^2 would be the case (pythagorean theorem). The a,b,c refers to the sides of the triangle. The 'c' is always the longest side, where 'a' and 'b' can be in any order you want.
We have
a = 13.5b = 17c = 21.7Which leads to
a^2+b^2 = c^2
(13.5)^2+(17)^2 = (21.7)^2
182.25 + 289 = 470.89
471.25 = 470.89
We don't get the same thing on both sides, so we don't have a right triangle.
However, your teacher mentions to round the results to the nearest whole number. The 471.25 on the left side becomes 471, while the 470.89 becomes 471.
So while the equation 471.25 = 470.89 is definitely false, both sides are close enough that they round to 471 = 471 which is true.
In other words, this isn't a right triangle but it's close enough to one. Based on this rounding criteria, Brian is correct.

Look at the following rules for two number patterns. Both patterns start with 40.
Pattern P: "Subtract 2"
Pattern Q: "Subtract 8"
Which statement is true about the corresponding terms in the two patterns?
Starting with 0, the difference between the corresponding terms in the two patterns decreases by 4.
Starting with 0, the difference between the corresponding terms in the two patterns increases by 6.
Excluding the first term, a term in Pattern P is always 6 greater than its corresponding term in Pattern Q.
Excluding the first term, a term in Pattern Q is always 8 greater than its corresponding term in Pattern P.
Answer:
Option CStep-by-step explanation:
Pattern P, the nth term formula:
Pₙ = 40 - 2nPattern Q, the nth term formula:
Qₙ = 40 - 8nThe difference is:
Pₙ - Qₙ = 40 - 2n - 40 + 8n ⇒ Pₙ - Qₙ = 6nIt shows the difference increase by 6 as the number of terms increase.
According the the difference of nth terms, the correct statement is:
Excluding the first term, a term in Pattern P is always 6 greater than its corresponding term in Pattern Q.A right triangle has a hypotenuse of 15. What are possible side lengths?

A rectangle has an area of 24 square meters. The width of the rectangle is 4 meters. What is the length of the rectangle? meters
Answer:
6 meters
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width.
Plug in 24 as the area and 4 as the width, then solve for the length (l):
A = lw
24 = l(4)
Divide each side by 4:
6 = l
So, the length of the rectangle is 6 meters
Answer:
6 m
Step-by-step explanation:
Area = width x length
Area= 24m²
Width= 4m
A= wl
24= 4 x l
[tex]\frac{24}{4}[/tex] = l

Six kids and two adults are going to the circus. Kid's tickets are on sale for only half the price of adult tickets. The total cost is $48. How much is one kids ticket? -how much is one adult ticket
Answer:
One kids ticket is $4.80 and one adult ticket is $9.60
Step-by-step explanation:
Create a system of equations where k is the cost of a kids ticket and a is the cost of an adult ticket:
6k + 2a = 48
k = 1/2a
Solve by substitution by substituting the second equation into the first one:
6k + 2a = 48
6(1/2a) + 2a = 48
Simplify and solve for a:
3a + 2a = 48
5a = 48
a = 9.6
Find the cost of a kids ticket by dividing this by 2, since they are on sale for half the price of adult tickets.
9.6/2
= 4.8
One kids ticket is $4.80 and one adult ticket is $9.60
What expression is equal to COS B????
Answer:
A/C
Step-by-step explanation:
Since the sum of the angles in a triangle equals 180°, and angle C is 90°.
That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.
We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.

Write the equation of the line that passes through the points (-6,5) and (3,−5). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
[tex]\displaystyle y-5=-\frac{10}{9}(x+6)[/tex]
Or:
[tex]\displaystyle y+5=-\frac{10}{9}(x-3)[/tex]
Step-by-step explanation:
We want to write the equation of a line that passes through the points (-6, 5) and (3, -5) in point-slope form.
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Thus, first, we need to find the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{(-5)-(5)}{(3)-(-6)}=\frac{-10}{9}=-\frac{10}{9}[/tex]
Next, we can use either of the two given points. I'll use (-6, 5). So, let (-6, 5) be (x₁, y₁). Substitute:
[tex]\displaystyle y-(5)=-\frac{10}{9}(x-(-6))[/tex]
Or, fully simplified:
[tex]\displaystyle y-5=\frac{-10}{9}(x+6)[/tex]
Using the other point, we will acquire:
[tex]\displaystyle y-(-5)=-\frac{10}{9}(x-(3))[/tex]
Or, simplified:
[tex]\displaystyle y+5=-\frac{10}{9}(x-3)[/tex]

Answer:
(8x + 100) litres
Step-by-step explanation:
According to the question,
Given, In a village there are 8 water tanks to collect rainwater. On a particular day, x litres of rainwater is collected per tank. If 100 litres of water was already there in one of the tanks.Therefore,
Number of water tanks = 8
Rainwater collected by each tank = x litres
∴ Rainwater collected by 8 tanks = 8x litres
But, 100 litres of water was already there in one of the tanks.
So, the amount of water in the tanks = (8x + 100) litresEach year, roughly 10^6 computer programmers each make about $10^5. How much money is this all together?

A student is given the following polynomial and is asked to answer questions about it:
x5−198x+5x12+4−2x6
The polynomial contains how many terms?
List all of the coefficients of the polynomial.
What is the polynomial’s constant?
What is the leading coefficient of the polynomial?
What is the degree of the polynomial?
Answer:
Step-by-step explanation:
A term is a combination of letters and/or numbers separated by a + or a - sign. Our polynomial has 5 terms.
A coefficient is a number stuck to a letter...it HAS to be stuck to a letter to be a coefficient. Our coefficients are 1, -198, 5, and -2 (notice I let out the 4).
That's because a constant is a number NOT stuck to a letter. The 4, then, is the only constant in this polynomial.
The leading coefficient is the number that is stuck to the highest-degree variable. Our highest degree variable is a 12 in 5x^12. So the leading coefficient is 5. In order to have a polynomial in standard form, we always list the terms in order of descending powers (highest power to lowest).
The degree is also the same as the highest power in our polynomial. Ours is a 12th degree.

A ping pong ball is released from a height of 60 centimeters (cm) and bounces to a height that is 3/4 the previous height. What function estimates the height, H, in cm of the ping pong ball after x bounces?
Enter a number in each empty box to correctly complete the function.
H = ____ (____)^x
Multiply the starting height (60) by the height of each bounce (3/4) raised to the number of bounces (x)
H = (60)(3/4)^x
The answer to the given expression is:
H = 60(3/4)^x
What do we mean by exponents?A number is raised by another number which is called the power/exponent which implies that the number is multiplied by itself for that many number of times.
How do we solve for H?After every release, it bounces 3/4th of the previously released height.
After 1st bounce H = 60(3/4)
After 2nd bounce, it will be 3/4th of the previous H,
∴ H = 60(3/4)(3/4) = 60(3/4)^2
Similarly, after the 3rd bounce, it will be 3/4th of the previous H,
∴ H = 60(3/4)^2 * (3/4) = 60(3/4)^3
So it goes on like this. After x bounces,
H = 60(3/4)^x

Because AB is parallel to DC, this means the consecutive interior angles B and C are supplementary (these angles are adjacent to either parallel line). They add to 180 degrees.

We use the same idea from earlier. This time we have two pairs of parallel lines instead of one pair. Adjacent angles in any parallelogram always add to 180.
R+I = 180
If R = 70, then angle I = 180-R = 180-70 = 110
If angle I = 110, then angle N = 70 (because I+N = 180)
If angle N = 70, then angle G = 110 (because N+G = 180)
As you can see, opposite angles of a parallelogram are always congruent.
