There are 215 total students in the band.
There are 27 seniors in the band.
The probability is found by dividing the number of seniors in the band by the TOTAL number of students in the band.
P(S|B) = 27/215 = 0.1255813953
You have to round off the answer too the nearest tenth.
P(S|B) = 0.13

Enter the equation of the circle with the given center and radius.
Center: (0,3); radius: 3
The equation of the circle is
Answers
Answer:
x² + (y - 3)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (0, 3) and r = 3, thus
(x - 0)² + (y - 3)² = 3², that is
x² + (y - 3)² = 9 ← equation of circle

Answer:
Vertical angles are congruent.
Step-by-step explanation:
Angles 1 & 4 are vertical angles. They are created using only two lines that cross(intersect). Line a and the unmarked, kind of diagonal line (its the transversal) intersect to create four angles. Two of them are marked Angle1 and Angle4; they are vertical angles. They are congruent.

Step-by-step explanation:
A florist orders roses and carnations. The roses cost $16 per dozen, and the carnations cost $9 per dozen. The florist orders a total of 18 dozens of roses and carnations for a total cost of $218.
How many dozens of roses does the florist order?
A. 6 dozen
B. 8 dozen
C. 10 dozen
D. 12 dozen
Answers
Answer:
B. 8 dozen
Step-by-step explanation:
Let r = number of dozens of roses.
Let c = number of dozens of carnations.
c + r = 18
9c + 16r = 218
-9c - 9r = -162
9c + 16r = 218
7r = 56
r = 8
Answer: B. 8 dozen
Answer: Its 8 dozen
Step-by-step explanation: 1. you multiply 8 times 16 and you get $128
2. you then multiply the remaining carnations by 9. 9 times 10 is $90
3. $128 + $90 is $218

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answers
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986

Find the area of this figure.
Answers
Answer:
144 ft^2
Step-by-step explanation:
We can split this shape into a rectangle and into a trapezoid. The rectangle we can use is the one with side lengths of 12.4 and 6, and to find this area we just multiply these two to get 74.4.
The trapezoid we can make has bases of 5 and 12.4, and has a height of 8 ft. The equation representing the height of a trapezoid is \(\\\frac{1}{2} (b_{1}+b_{2} )*h\), and plugging in to this equation we get:
1/2(5+12.4)*8
1/2(17.4)*8
8.7*8
69.6
Finally, we add the area of the trapezoid and rectangle together to get 69.6+74.4=144

However, since it is still equaling to a negative exponent of 2, we must convert it into a positive fraction.
We can simply do this by putting a “1” on the top, as a numerator, and 12^2 on the bottom as a positive power.
Therefore, your answer is 1/12^2.

Answers
Answer:
2.5 cm
Step-by-step explanation:
Rectangle A L x W = 40
Rectangle B L * W = 1/2 (40)
8 * W = 20
W = 2.5 cm
Answer:
The width of B. is 2.5cm
Step-by-step explanation:
Rectangle A has 40cm^2 and a length of 8.
Rectangle B. has an area half of 40cm^2 which would be 20cm^2.
Area of B has an area of 20cm^2
Now we need to find the width of B.
All that we know is that B. has an area of 20cm and it has the same length as A, and that length is 8.
Everyone knows that you multiply the length by the width to find the area of a shape.
8 times something = 20
We can do that backward and divide 8 by 20 which is 2.5
To check this answer we multiply 2.5 by 8 which = 20
The width of rectangle B. is 2.5cm.

Answers
Answer:
Step-by-step explanation:
7x+9=2x+39
7x+9-9=2x+39-9
7x=2x+30
7x-2x=2x+30-2x
5x=30
5x/5=x
30/5=6
x=6
Answer:
X=6
Step-by-step explanation:
7x+9=2x+39
First, subtract 9 from both sides like this
7x+9 -9 =2x+39-9
equaling 7x=2x+30
Then, subtract 2 from both sides like this
7x - 2=2x -2+30
equaling 5x=30
Lastly you divide 5 from both sides like this
5x / 5 = 30 / 5
equaling x=6
